Rendering can involve lots of pushing and shoving, if you use a ladder, but hire a scaffold tower and you will be able to enjoy the experience as you evolve from a beginner to a rendering artist as you go from wall to wall Find heras fencing panels.
Whether you create art or not from your scaffold tower is very much down to how prepared and practised you are.
Let’s get the niggly little questions answered first.
What is the Difference Between Rendering and Plastering?
Only internal walls are plastered, because the plaster contains gypsum that will crumble when it’s exposed to moisture. Consider what happens to plaster when the damp gets in… not really ideal for outside, is it?!
Rendering is a far stronger material, which will resist water on outside walls. Rendering is a very old practice, originating in Australia where settlers protected their houses against the elements with a mix of cement, lime and sand. Rendering has come a long way since its humble beginnings and is now a popular way to protect houses worldwide.
Of course the industry has moved on and developed renders that use acrylics, polystyrene and colour to create more durable, flexible render limes and cements. Render no longer just protects houses, it decorates them too!
Make sure you take advice when you shop for your render; check that the render you buy is appropriate for the substrate: get the wrong one and you’ll be doing it all again in a few months.
Initially hire a scaffold that accesses all of your wall. For a 2-storey house you need a 5.2 metre tower. Hiring scaffold tower is exceedingly beneficial as it allows you to reach larger sections of the wall, so you’ll get a smoother, more even application; you won’t have to shunt and push a stepladder around, which wastes time and energy.
Hired scaffold towers are quick to assemble and lock securely into position, making it easy for you to have quick access to your rendering materials: rag, scoop, plastic float, wire brush, container for mixing the render (wheelbarrow or cement-mixer) and enough render lime or cement to cover your wall.
If you have paint on your wall, use a gel or paste remover, then use a low-pressured washer to clean the rest of the walls.
Once you have a completely cleaned wall, you’re ready to apply the undercoat (two if you live in a particularly exposed area, or none if you have a ‘monocouche’ render, which doesn’t require an undercoat). Your undercoat should be about 8 – 12 mm thick.
