Everything you need to know about rendering tools.
The best render jobs are those that you are most prepared for. Here are our essential tools that any installer should have on-site to apply your EWI Pro render.
When rendering external walls there are many different tools and equipment that is needed to get the best finish.
One of those tools you need includes a trowel – there are many different types of trowels for example a plastering trowel can be used for applying the the base coat layer in any render or external wall insulation system. A notch trowel is typically used for applying the first layer of the base coat to create a textured surface to increase the adhesion of the second coat. The bucket trowel is used for mixing, scooping and scraping product in the bucket. There are many other trowels including; a corner trowel and pointing trowel and a pebble dashing trowel. Another important piece of equipment used is rendering tape!, and yes this is just as important as any of the other tools. The rendering tape helps you create smooth lines and a clean finish around any windows. Along with tape you can also use other things such as a swifix satellite plate fitting and a swifix tap fitting etc to protect the other exterior parts of you home.
Adding EPS First
If, before you render you home, you’re going to externally insulated it then you need a few extra tools. Your’e going to need a bucket trowel to apply the adhesive onto the EPS, then using a spirit level to push the board into lace evenly. Mechanical fixings are then added to the insulation using a drill and hammer. The whole surface will then be made smooth and flat using the rasp.
How to achieve a clean finish
Once you have added the base coat, corer beads and mesh, using a trowel, to reinforce the system you can start the rendering process. First you will use a roller or brush to apply your primer, then use a flat edge trowel to apply your render. To achieve a nice even texture you can use aplastic float to smooth out any lumps and bumps and finally, once dry you can use a sponge float to really get a clean finish.
