Then once you are a bit more familiar with plastering the fixing of angle beads will be a lot easier.Īll rights reserved. If you have a wall with no external corner plaster this first – angle beads are explained later. If you have an external corner on your wall then your first job is to fix an angle bead on the corner – this will give you a straight edge to work to whilst also setting the thickness for the whole. Sometimes the thickness will be set for you – if you have a door lining in the wall, then the backing coat should finish flush with this lining. The thickness of backing coat will depend upon the wall you are working on. If the wall you’re plastering is flat and has no cables that need to be buried you may be able to apply a coat of 10mm or less. Therefore a skim coat should be sufficient.Īverage thickness of a backing coat is 10 to 12 mm thick. Previously Plastered Surfaces - for example – when the wallpaper has been removed in old houses the wall behind although flat may be in too poor a condition to apply paint. If for some reason the plasterboard is not flat then a backing coat of ‘Bonding Coat’ can be applied. Plasterboard walls - the plasterboard acts as the backing coat as it is totally flat.

Very few have drywall, and some with drywall have since been plastered over by the previous owner.This plastering guide will take you through each stage of plastering. What is skim coating and WHY did we need it? Well, most of the walls in our house are plaster. So, the plan was to remove the wall paper so we could have our trusty skim-coating team come in and take over. But, there was no rush to finish this project and LOL we still don’t have floors in our kitchen, but priorities I guess?! BUT, it was an easy project, and we were just SUPER over that obnoxious red wallpaper. In the future these two rooms will likely serve as a guestroom, and an office for Dan. However, as it turns out, multiple bedrooms are a benefit to future homeowners. Currently, those two rooms serve zero purpose to us #nokids #noroomies. As I mentioned in our #housegoalz post a few weeks ago, one of the items on that list was to finish up the two spare bedrooms upstairs.
