How to replaster a wall
With the increasing costs of professional plasters, why not give it a go yourself. You'll be supprised that with a little practice you can do a good plastering job.
What you'll need:
Large Paint brush
Preperation of the wall: Brush down the wall and pva the wall. If the wall has large chunks of plaster missing roughly fill with plaster. Leave to dry
Mix the plaster in a bucket. Add water to the bucket then pour in the plaster, using the mixer mix until you get a smooth thick creamy consistancy. When the plaster is at the correct consistancy the plaster won't fall off the hawk, but will be smooth enough to easily apply.
Get some clean water into a bucket. Wet the ply-board and pour the plaster onto the board. Scoop some plaster onto the hawk with a flicking action. Move the plaster between the hawk and the trowel, don't worry if you drop the plaster on the wall, practice makes perfect.
Start at the top left hand side of the wall and slowly apply the plaster to the wall. You are looking for a thinkness of no more than 2-3mm. Don't worry about it being not to even at this stage. Continue until all the wall has a coat of plaster on.
Give the plaster a quick smooth over with the trowel to get rid of some of the unevenness, if the plaster feels a bit dry flick fome clean water on. Then leave go and make a cup of tea! You need to leave the plaster to set so when you touch the plaster with your finger there is some resistance. Times differ depending on the heat of the room, it could be as quick as 5 minutes or up to 20.
Smoothing the first layer: Get a wet paintbrush and flick some water onto the plaster, smooth with the trowel, you are not looking at getting a finished look but not too far off.
Mix up some more plaster, and apply a second coat to the wall. This coat should be a very thin coat as approx 1mm. This coat only fills holes and even out depressions. Again leave to set, this could be up to 30-40 minutes. Get another cup of tea.
Again get some clean water in a bucket. Start again at the top left hand side flick some water onto the wall using the brush, smooth the plaster out with the trowel. Be careful not to over do it as you will start ruin the smoothness. If you are still not happy with the end result repeat the process.
That's it your done! Leave to dry before adding a coat of paint, Remember if there are still some small imperfections you can fill using polyfilla.
Go for - it give it a go, following these steps you will be surprised at your end result. Buy a decent trowel, I use a marshalltown as the edges have already being ground out.
