    Frequently Asked Questions
    Why did my Adhesive Nail fall off the wall?

    You may not have used a silicone-free window cleaner, methylated spirit or isopropanol to clean the surface (other detergents may render the adhesive ineffective). It could also be that the surface is insufficiently smooth and firm.


    How do I apply an Adhesive Strip?

    To see how easy it is to apply an Adhesive Strip for Tiles & Metal, have a look at our step-by-step guide tesagroup.net/consumer_new/smart-mounting-system/how-to-use">here.
    To find out how to apply Adhesive Strips to Wallpaper & Plaster, see our step-by-step guide tesagroup.net/consumer_new/smart-mounting-system/how-to-use">here.


    How do I remove an Adhesive Nail?

    In a word: slowly. Gently pull the non-adhesive tab at the end of the strip downwards in parallel to the surface (NOT away from it) to stretch it. Take care not to press the nail against the surface as this can stop the strip from stretching.


    Why do I have to stretch an Adhesive Nail to remove it?

    The Adhesive Strip holds your object with flexible polymer U-shaped chains. When they’re holding your object these chains can hold up to XKG. When you stretch them to remove, the chains adjust and do not hold on to the substrate anymore, so the strip can be removed.


    What if the tab breaks when I pull it?

    This rarely happens. As long as the surface is strong (like glass or tiling) you can gently but firmly twist the hook. The flexible polymer U-shaped chains adjust and do not hold on to the substrate anymore, so you can remove the hook.


    What surfaces are suitable for Adhesive Nails?

    Please make sure the surfaces you want to apply the Adhesive Nails to are sufficiently strong. They work best on smooth, flat surfaces like glass, ceramics (tiles), wood and most plastics. Varnished and lacquer surfaces are fine, too, though it can be difficult to remove the strip without damaging the surface if it’s porous.


    Can I use Adhesive Nails on varnished or lacquer surfaces?

    The short answer is ‘yes’. The slightly longer answer is ‘it depends on the quality of the lacquer’. If it’s slightly porous or if it’s non-stick then the adhesive won’t be effective.


    Can I use Adhesive Nails on dispersion paint?

    Mounting an Adhesive Nail on dispersion paint is fine – but if the paint is very delicate or porous then removing it later on without damaging the finish can be tricky. It’s important to test the load-bearing quality of your surface before applying an Adhesive Nail.


    How do I prepare a surface before using Adhesive Nails?

    Use a silicone-free window cleaner, methylated spirit or isopropanol to clean the surface. Steer clear of regular domestic detergents and they can affect the adhesive’s power.


    Can I use Adhesive Nails on ingrain wallpaper and plaster?

    That’s why we’ve developed Adhesive Strips for Wallpaper & Plaster with a foam core and a less viscous adhesive, this results in a larger bonded area and it’s less likely to damage delicate surfaces when removed.


    Can I use Adhesive Strips on coated paper (e.g. specialized art papers)?

    No, we don’t recommend it! There can be a reaction between the coating and the adhesive that may discolour the paper.


    Can I use Adhesive Nails on brick walls?

    We don’t recommend it – but you should have a look at our range of Adhesive Screws, Mounting Glue and Mounting Tape for Brick & Stone.


    Can I use Adhesive Nails on sheetrock?

    We’re afraid not – when it comes to wall mounting, sheetrock is too sensitive even for a product as adaptable as Adhesive Nails.


    Can I use Adhesive Nails on natural wood?

    Natural woods may be waxed or oiled, and we don’t recommend using Adhesive Strips on such surfaces.


    Can I use Adhesive Nails on roof slopes?

    It can get hot under roofs during the summer and this heat – combined with the fact that sloping surfaces exert forces that Adhesive Nails were not designed to withstand can severely reduce the load-bearing ability of Adhesive Nails.


    Can I use Adhesive Nails on vehicles?

    We can’t recommend it. Cars go through a lot – extremes of heat and cold, not to mention condensation. They’re also made of a variety of plastics (e.g. PE or PP), some of which may not be suitable for Adhesive Strips.


    Will the Adhesive Nails work on rough surfaces?

    Rough or uneven surfaces reduce the Adhesive Nail’s sticking power, so whilst it won’t do any harm to the surface, it may not be worth the risk. We don’t recommend it and advise you to better try our Adhesive Range for Brick & Stone for this purpose.


    Can I use Adhesive Nails outside?

    No. Extremes of temperature, generally rough surfaces and rainfall mean that outdoor application isn’t recommended.


    Can Adhesive Nails handle the cold?

    Yes. The optimal temperature for application is between 20°C and 25°C (min. 15°C), but after the adhesive has taken hold then it won’t mind the cold at all.


    Can I use Adhesive Nails in hot climates?

    That depends on how hot you mean. They’ll work perfectly up to 35°C and even up to 40°C for short periods, but temperatures in excess of this will impact their
    effectiveness.


    How do I apply mounting tape?

    You’ll find a step-by-step guide here.


    What surfaces are suitable for the various types of mounting tape?

    The clue’s in the title. Perhaps it’s best to say which tapes are unsuitable for which surfaces!


    What surfaces can’t I use Mounting Tape for Wallpaper & Plaster on?

    Non-stick surfaces like silicon, stain resistant paint and PTFE are a problem for almost all adhesives – and this Mounting Tape is no different. It is also ineffective on vinyl wallpaper.


    What surfaces can’t I use Mounting Tape for Transparent & Glass on?

    We can’t think of any transparent surfaces that this won’t stick to like glue. But if you do manage to find one that’s made of silicone, PTFE or one that’s been painted with stain-resistant paint, then we’re afraid it’s not going to work.


    What surfaces can’t I use Mounting Tape for Brick & Stone on?

    This Mounting Tape can bear a lot! But if the surface you want to mount something on is too rough or uneven, the Mounting Tape won’t work to its full potential.


    What surfaces can’t I use Mounting Tape for Tiles & Metal on?

    It’s stick to pretty much anything that’s not non-stick, so steer clear of silicon, stain resistant paint and PTFE.


    How do I prepare a surface before using Mounting Tape?

    For perfect results ensure both the object you are mounting and the surface it’s being mounted on are clean of dust, dirt and grease. Use a lint-free cloth with alcohol or a silicone-free detergent on smooth surfaces, and if the surface is rough then use a brush.


    FAQs to help you find out which of the tesa® Mounting Tapes is the right tool for the job – and what impact the elements may have on their efficacy.

    The tesa® Mounting Tape mounting system comes in a variety of forms to match the variety of wall mounting tasks. Here are some commonly asked questions that’ll help you decide which tape is right for your intended environment.


    Can I use Mounting Tape for Brick & Stone outside?

    Our weather-resistant Mounting Tape for Brick is tailor made for brickwork, whether it’s inside or outside. The other varieties are designed to be used inside, however.


    Can Mounting Tapes be damaged by UV radiation?

    Mounting Tapes for Brick & Stone, for Tiles & Metal, and for Transparent & Glass are all UV resistant.


    Are Mounting Tapes effective in cold climates?

    Yes – absolutely, though their adhesive power will be affected by temperatures below -10°C.


    Are Mounting Tapes effective in hot climates?

    Generally, yes. They’ll all work perfectly up to 40°C, and Mounting for Tiles & Metal works perfectly in even hotter conditions – up to 80°C.


    Will two Adhesive Screws work better than one?

    In theory, two adapters will hold twice as much as one - but make sure that the load is distributed equally. We don’t recommend using more than two at a time.


    Can I use the system with objects other than those supplied?

    Absolutely – though we can’t guarantee that you’ll get the perfect fit, of course. So we recommend using products designed for the nie wieder bohren. Technology, which is why we’ve developed adapters of various shapes and sizes and a range of covers.


    The adapter from my Adhesive Screw fell off the wall. Why?

    In our experience there are very few reasons why an Adhesive Screw may fall off due to:
    1. Cavities in the adhesive layer: Sometimes people press down on the screw after they’ve applied the adhesive, forcing it out of the cavity and producing air pockets that diminish the screw’s grip.
    2. Insufficient curing time (give it 12 hours minimum). For very rough surfaces the adhesive layer is a little thicker, so it can take longer for the adhesive to set.
    3. Conventional household cleaner being used on the surface prior to application. Conventional household cleaners often contain de-greasers or water-resistant components on which the adhesive has no hold.
    4. Unsuitable surfaces
    Although our Smart Mounting System is suitable for almost all common wall-mounting jobs, there are certain plastics on which the adhesive is ineffective such as polyethylene (PE), polypropylene (PP) and Polytetralfluorethylen (PTFE, Teflon).


    Is the adapter reusable?

    Sadly not. Even if you’re able to remove it without damaging it, it would be impossible to remove every trace of the hardened adhesive and thus make it permeable to air again – and it’s the moisture in the air that reacts with the adhesive and makes it so strong.


    How and why is the Adhesive Screw removable?

    We’ve designed the Adhesive Screw to be removable so that, unlike with other mounting systems, there’s no need to damage the surfaces. Simply grip the screw using an adjustable wrench and twist to release the bond.


    How can such a strong mounting system be so easy to remove?

    Our adhesive solution is highly resistant to load bearing forces like the one that a hanging object exerts on it but not to torsion (twisting), which is why you can twist the Adhesive Screw off the wall when you’re finished with it.


    What types of surfaces are the Adhesive Screws suitable for?

    Adhesive Screws work on most common household surfaces where you might want to mount something and where drilling might be impossible or undesirable. These include stonework, tiles, glass, wood, concrete and most plastics. Adhesive Screws aren’t designed to be used on use on soft plaster, wallpaper or fabrics, however.


    Will the Adhesive Screws work on rough surfaces too?

    Adhesive Screws are great for wall mounting on smooth surfaces but they’re even better on slightly rough ones. The surface does need to be flat, though, so that the adhesive doesn’t seep out under the adapter ring.


    Can the adhesive in Adhesive Screws damage my surfaces?

    We’ve never found a load-bearing surface that will be damaged by the chemicals in the NWB adhesive. However, it can be difficult to remove the adhesive completely from some porous surfaces, so it’s wise to carry out preliminary tests first.


    Are Adhesive Screws suitable for outdoor use, too?

    Absolutely – but it’s important to apply them between 5°C and 40°C and, once applied, it’s a good idea not to keep them permanently under water. Otherwise, because the adhesive is resistant to UV light and doesn’t mind freezing conditions, Adhesive Screws are effective whatever the weather.


    Does the adhesive in the Adhesive Nails contain formaldehyde?

    No, the adhesive in Adhesive Nails does not contain formaldehyde.


    Is the adhesive in Transparent Adhesive Hooks toxic?

    No, don’t worry the adhesive we use in our Transparent Adhesive Hooks isn’t toxic.


    Does the adhesive in the Transparent Adhesive Hooks contain formaldehyde?

    No – we’ve developed the adhesive in Transparent Adhesive Hooks without using formaldehyde.


    Why did my Adhesive Hook fall off the glass?

    Perhaps you didn’t use a silicone-free window cleaner, methylated spirit or isopropanol to clean the surface (other detergents may render the adhesive ineffective), or it could also be that the surface is insufficiently smooth and firm.


    How do I apply an Adhesive Hook?

    How do I remove an Adhesive Hook?

    Take hold of the hook with one hand and grab the clear tab at the end of the strip with the other. Then, without pressing the hook to the glass, gently stretch the strip downwards, parallel to the surface.


    How does stretching the strip behind the hook remove it?

    The Adhesive Strip holds your object with flexible polymer U-shaped chains. When they’re holding your object these chains can hold up to XKG. When you stretch them to remove, the chains adjust and do not hold on to the substrate anymore, so the strip can be removed.


    What if the tab breaks when I pull it?

    This rarely happens. As long as the surface is strong (like glass or tiling) you can gently but firmly twist the hook. The flexible polymer U-shaped chains adjust and do not hold on to the substrate anymore, so you can remove the hook.


    What surfaces are suitable for Adhesive Hooks?

    Please make sure the surfaces themselves that you want to apply the Adhesive Hooks to are strong enough to take the weight of the object you’re mounting. Our hooks adhere best to flat, smooth surfaces like ceramic tiles or glass. Varnished and lacquer surfaces are also okay, though it can be a bit tricky to remove the strip without damaging the surface if it’s porous.


    Can I use Adhesive Hooks on varnished or lacquer surfaces?

    The short answer is ‘yes’. The slightly longer answer is ‘it depends on the quality of the lacquer’. If it’s slightly porous or if it’s non-stick then the adhesive won’t function properly.


    Can I use Adhesive Hooks on dispersion paint?

    Absolutely, but bear in mind that if the paint is very delicate or porous then removing the Adhesive Hook without damaging the surface can be difficult. And again, please also make sure the surface itself is strong enough to take the weight of the item you’re mounting.


    How do I prepare a surface before using Adhesive Hooks?

    Use a silicone-free window cleaner, methylated spirit or isopropanol. Avoid using regular domestic detergents because they can affect the adhesive’s strength.


    Can I use Adhesive Hooks on ingrain wallpaper and plaster?

    No, we don’t recommend it – that’s why we’ve developed Adhesive Strips for Wallpaper & Plaster with a foam core and a less viscous adhesive. This results in a larger adhesive surface and it’s less likely to damage sensitive surfaces when removed.


    Can I use Adhesive Strips on coated paper (e.g. specialized art papers)?

    We don’t recommend it! There can be a reaction between the coating and the adhesive that can discolour the paper.


    Can I use Adhesive Hooks on brick walls?

    Rough or uneven surfaces have an adverse affect on Adhesive Hook’s sticking power so, although it won’t do any harm to the bricks, we don’t recommend it, you’ll be better off using our Adhesive Screws.


    Can I use Adhesive Hooks on sheetrock?

    We don’t advise it – when it comes to wall mounting, sheetrock is simply too sensitive.


    Can I use Adhesive Hooks on natural wood?

    Natural woods are often waxed or oiled, so we can’t recommend using Adhesive Hooks on these surfaces.


    Can I use Adhesive Hooks on vehicles?

    We can’t recommend it. Cars go through a lot – extremes of heat and cold, not to mention condensation. They’re also made of a variety of plastics (e.g. PE or PP), some of which may not be suitable for Adhesive Strips.


    Can I use Adhesive Hooks outside?

    No. Extreme heat, generally rough surfaces and rainfall mean that we don’t recommend using Adhesive Hooks outside.


    Can Adhesive Hooks handle the cold?

    Yes. The optimal temperature for application is between 20°C and 25°C (min. 15°C), but after the adhesive has taken hold then it won’t mind the cold at all.


    Can I use Adhesive Hooks in hot climates?

    Transparent Adhesive Hooks will work perfectly in environments up to 35°C and – for short periods even up to 40°C. Higher temperatures will impact their effectiveness.


    Can I use Adhesive Strips outside?

    No. Due to changing temperatures (hot and cold), generally rough surfaces and rainfall, outdoor application is not recommended.


    Can transparent Adhesive Strips be damaged by UV radiation?

    Their UV resistance depends on the level of UV radiation and UV exposure time. Very high exposure might affect the removability of the die-cuts, though the adhesive bonding itself is not affected by the UV conditions.


    Are Adhesive Strips effective in cold climates?

    Yes – absolutely. The optimal temperature for application is between 20°C and 25°C (min. 15°C), but after the adhesive has taken hold then the cold won’t harm it at all.


    Are Adhesive Strips effective in hot climates?

    Yes and no. How hot are we talking? They’ll work perfectly up to 35°C and even as far as 40°C for short periods, but temperatures in excess of this will impact their effectiveness.


    Why do I have to stretch an Adhesive Strip to remove it?

    The Adhesive Strip holds your object with flexible polymer U-shaped chains. When they’re holding your object these chains can hold up to XKG. When you stretch them to remove, the chains adjust and do not hold on to the substrate anymore, so the strip can be removed.


    How do I remove an Adhesive Strip?

    If you’re using an Adhesive Nail or Adjustable Adhesive Screw, take hold of the head with one hand and grab the clear tab at the end of the strip with the other. Then, without pressing against the surface, gently stretch the strip parallel to the surface – not away from it. You can see how it’s done tesagroup.net/consumer_new/smart-mounting-system/how-to-use">here.


    I’m having trouble removing the strip. What should I do?

    If the surface is solid and the object strong, you can gently but firmly twist to break the bonds, and then remove the strip from the back of the object afterwards.


    What if I pull too hard and the strip breaks?

    Don’t panic! So long as the surface is strong (like glass or tiling) you can gently but firmly twist the object to break the bond and then remove the remainder of the strip afterwards.


    What should I consider before removing an Adhesive Strip?

    To release the object from the surface, simply take hold of the clear tab at the end of the strip and – without pressing the nail or object to the surface, gently stretch the strip in parallel to the surface. Don’t forget to support the object that’s about to come unstuck! But never press it against the wall.


    Why is the tesa® Adhesive Strip longer than it used to be?

    Especially when it comes to sensitive surfaces like plaster and wallpaper, we need to balance the strength of the adhesive with ease of removal. Making the Adhesive Strip just a little longer enabled us to do that without compromise.


    Does an Adhesive Strip contain toxic or acidic chemicals?

    Absolutely not – each tesa® Adhesive Strip is made of non-toxic synthetic rubber.


    Is an Adhesive Strip appropriate for mounting a smoke alarm?

    We don’t recommend overhead bonding. After all, smoke alarms come with their own specially-designed mounting system enclosed.


    How much weight will an Adhesive Strip support?

    It depends on which product you choose but also how far from the wall your item sticks out - holding power is a combination of weight and leverage, so the more it sticks out, the more pressure it exerts on the strip! For example, the Adhesive Strip for Tiles & Metal 3kg can hold objects up to 3kg which have a depth of up to 5cm. The Adhesive Strip for Wallpaper & Plaster 2kg can hold objects up to 2kg which have a depth of up to 1cm.


    How does a tesa® Adhesive Strip work?

    The Adhesive Strip holds your object with flexible polymer U-shaped chains. When they’re holding your object these chains can hold up to XKG. When you stretch them to remove, the chains adjust and do not hold on to the substrate anymore, so the strip can be removed.


    Why might I need the new tesa® Adhesive Strips for Wallpaper & Plaster?

    Three reasons.
    1 – The foam core helps overcome any unevenness of the surface.
    2 – The adhesive is less viscous so you get a closer bond.
    3 – It’s also softer, so there’s even less chance of damaging delicate surfaces when you come to remove it.


    How do I apply an Adhesive Strip?

    To see how easy it is to apply an Adhesive Strip for Tiles & Metal, have a look at our step-by-step guide tesagroup.net/consumer_new/smart-mounting-system/how-to-use">here.

    What are Double-Sided Adhesive Pads useful for?

    These little Adhesive Pads are great for mounting paper and postcards (up to DIN A3 format) on smooth, firm surfaces like tiles, glass, metal and acrylic. They’re not suitable for rough surfaces, however, or non-stick surfaces such as vinyl wallpaper, PE and PP.


    What kind of things should I use an Adhesive Strip for?

    It maybe easier to ask what wall-mounting tasks an Adhesive Strip can’t handle! Therefore, see the question below. But to give you some idea on how to use it: Try fairy lights, door wreaths, pictures, led strip lights, flags. We could go on and on…


    What wall mounting tasks can’t an Adhesive Strip handle?

    This is a pretty short list - but not comprehensive: Smoke alarms, soap dishes, toilet paper holders, lamps, roller blinds. For all these there’s probably tesagroup.net/consumer_new/smart-mounting-system/mounting-solution">another tesa® Smart Mounting System solution that’ll do the job.


    What happens if I use Adhesive Strips for Wallpaper & Plaster on tiles, glass, brick etc.?

    Our Adhesive Strips are highly effective adhesive solutions even in the hands of subversives like you! Go ahead – use the wallpaper-optimized Adhesive Strips on different materials: They work just fine, but they won’t be quite as strong, because their holding power depends on both weight and dimensions of the object you want to stick to the wall. Click tesagroup.net/consumer_new/smart-mounting-system/faq/adhesive-strips">here to see how much each type of strip can hold and why.


    What surfaces are suitable for Adhesive Strips?

    They work best on smooth, flat surfaces like glass, ceramics (tiles), wood and most plastics, and the Wallpaper & Plaster ones are great for many more sensitive surfaces (not suitable for vinyl wallpaper or non-stick surfaces e.g. silicon). Varnished and lacquer surfaces are usually fine, though if they’re porous it can be difficult to remove the strip without damaging the surface.


    Can I use Adhesive Strips on windows?

    Adhesive Strips Transparent will work just fine for a certain amount of time. Their UV resistance depends on the level of UV radiation and UV exposure time. The Adhesive Strips For Tiles & Metal and those for Wallpaper & Plaster are not suitable for windows as they are not UV resistant. Very high exposure might affect the removability of the die-cuts, though the adhesive bonding itself is not affected by the UV conditions.


    Can I use regular Adhesive Strips on ingrain wallpaper?

    No, we don’t recommend it – that’s why we’ve developed dedicated Adhesive Strips Wallpaper & Plaster with a foam core and a less viscous adhesive, this results in a larger bonded area and it’s less likely to damage delicate surfaces when removed.


    Can I use Adhesive Strips on Varnished or Lacquer Surfaces?

    The short answer is ‘yes’. The slightly longer answer is ‘it depends on the quality of the lacquer’. If it’s slightly porous or has non-sticky characteristics then it does not stick.

    Here you will find all our removable adhesive strips.


    Can I use Adhesive Strips on dispersion paint?

    Generally speaking, wall mounting on dispersion paint is fine – but if the paint is a little bit porous then removing the Adhesive Strip later on without damaging it can be difficult.


    Can I use Adhesive Strips on my car windows?

    Transparent Adhesive Strips may be used in the short term as they have a limited UV resistance. However, due to the likelihood of temperatures inside a car rising beyond 40°C, we don’t generally advise it.


    How do I prepare a surface before using an Adhesive Strip?

    Use a silicone-free window cleaner, methylated spirit or isopropanol to clean the surface and allow to dry. Do not use regular detergents and they may render the adhesive ineffective.


    Can I use Adhesive Strips on in-grain wallpaper and plaster?

    The surface needs to be sufficiently smooth and firm, otherwise the adhesive power is strongly reduced. We recommend using Adhesive Strips for Wallpaper & Plaster for such delicate surfaces.


    Can I use Adhesive Strips on coated paper? (e.g. specialized art papers)

    We don’t recommend it! There can be a reaction between the coating and the Adhesive Strip that can discolour the paper.


    Can I use Adhesive Strips on brick walls?

    Rough or uneven surfaces reduce the Adhesive Strip’s effectiveness significantly, so whilst it won’t do any harm to the surface, it may not be worth the risk. Click tesagroup.net/consumer_new/smart-mounting-system/mounting-solution">here to see out range of smart wall-mounting solutions for brick and stone.


    Can I use Adhesive Strips on sheetrock?

    Alas, no – when it comes to wall mounting, sheetrock is too sensitive even for our Adhesive Strips.


    Can I use Adhesive Strips on glass windows and doors?

    Only our Adhesive Strips Transparent have some protection against the degrading effects of UV light.


    Can I use Adhesive Strips on natural wood?

    Since many natural woods are waxed or oiled, we can’t recommend it.


    Can I use Adhesive Strips on ceilings?

    We don’t advise overhead bondings – they exert a directional pressure on the strips that they aren’t designed to handle.


    Can I use Adhesive Strips on roof slopes?

    It can get really hot under roofs in the summer and this heat – combined with the fact that sloping surfaces exert forces that Adhesive Strips were not designed to withstand - can cause the bond to be broken.


    Can I use Adhesive Strips on vehicles?

    We don’t advise it. Cars go through a lot – extremes of heat and cold, not to mention condensation. They’re also made of a variety of plastics (e.g. PE or PP), some of which may not be suitable for Adhesive Strips.


    Can I apply Double-Sided Adhesive Pads to in-grain wallpaper?

    No – the surface simply isn’t smooth and firm enough for Adhesive Pads to get a proper grip.
