Masking when Spraying Plaster
Spraying plaster instead of applying it in the traditional manner with a hawk and trowel, can save you time and reduce waste. We have a range of tapes specifically for this application where a need to withstand heavy materials is required
Decorators are increasingly turning their hand to applying plaster or spray filler with a heavy duty spray machine, but why would you want to spray plaster instead of apply it in the traditional plastering way?
Spray plaster, or as it is also known as spray filler, can be applied quicker and cleaner than traditional methods and by using spray plaster, you can also reduce waste - compared to unused traditional plaster mix that can go hard once the bag has been opened, spray plaster comes ready mixed (wet) and in plastic drums with a long shelf life which can be stored away ready for the next job.
Along with these benefits, spray plaster is less brittle than traditional plaster, the filler cures quicker, the spray plaster can be tinted to the final colour, some fillers may not need a mist coat and as the decorator is now in control of this process without having to wait for the plasterer this means they can turn the job around even quicker. Despite the high initial cost of purchasing the machinary, the quicker turnaround time of the job means you can re-coup the cost of the machine in no time at all.
Paper masking tapes are perfect for painting but they can come up short when dealing with the thicknesses and heavy weight of spray plaster. Think of the surfaces that you wish to apply the plaster too brick, breeze block or concrete, in their nature these are not smooth, they can be dusty and are pourous which can cause some adhesive tapes to fail.
Our range of masking tapes for spraying plaster are based on waterproof, hand tearable cloth, PVC and now our new environmentally friendly PE tapes. They can be applied on cold or damp brickwork or concrete, for eample if you are looking to create a new room by converting an old basement.
What separates these products from normal duct tapes that are commonly used in these applications?
Our cloth backed tapes for plastering are all UV resistant so the adhesive is not cooked to the surface when working outdoors or near windows and doors, furthermore all out plastering tapes are waterproof, have strong adhesives to make sure they reliably stay bonded to the surface and furthermore can be removed without leaving residues or damaging the brickwork or concrete.
The new tesa 4845 not only has impressive performance stats:
- Temperature resistance during use: -40 °C to 60 °C.
- Application temperature: -15 °C to 30 °C.
- Residue-free UV: 12 weeks
It also has impressive environmental stats:
- Polyethylene (PE) is a thermoplastic, more environmentally friendly plastic that is recyclable and burns without leaving any residue
- PE is also used often for plastic bottles, kitchenware, plastic bags, foils, plastic tubes etc.
- During the production of PE films, there are no unpleasant odours or waste water. The use of raw materials, energy consumption in production, water consumption, weight and space requirements in landfills are lower with PE films than with comparable materials.
Aswell as tape, we now have tesa Easy Cover® 4369 - 2 in 1 tape and film solution for spraying plaster around windows or doorways or just protecting areas that you want to protect from overspray indoor and out. The film on our tesa® 4369 is stronger than the tesa Easy Cover® film you will find for spraying paint which you would expect considering the weight and pressures that it would need to withstand during the spraying process.
