General damages would normally be in the form of cracks, chunks or damaged corners. One cause could be from stripping wallpaper you can end up with wall that looks like it’s had a little bullet holes and entered into the wall. If there are so many it would be better to call us and get it done professionally.
If it’s only a couple of cracks or small jobs you can do it yourself here’s how.
To start you need to sit down cos it’s going to be quite dusty and messy and you don’t want any mess on furniture or other valuables. Moving forward you’ll need to dig out the crack a bit wider with the blade therefore making it more flush and easier to apply the plaster. then vacuum out the dust so that its nice and clean. lightly dampen the areas that have been affected, then when you are ready to move over the filler or plaster you have to fill the cracks but remember to remove the filler before it dries on places you do not desire it to be necessary.
To finish off you will need to sand down and and make sure it’s nice and smooth so when painting or decorating over the top it will look more level and not as sand like texture.
Now if it is corner damage which is pretty common you will need to apply filler. However because of gravity it will just fall over time so you will need to put masking tape or sellotape around all sides once you have roughly gauged the shape so that it will stay quite fixed to the corner and will not fall, as long as you have mixed the filler nicely like the others section it should be all good. Then just like the first paragraph to finish off and have a presentable look ,give it a nice sand down to deliver the perfect finish.
Chunks of missing plaster
If you have had chunks of plaster fall out of your wall for any reason, there could be a number of reasons for this. Then this is how you would fix this problem. If this has happened in your home then it’s better to not just put loads of filler in because it will look unprofessional and you will not be satisfied with the result. This needs to be actual plaster because it will last longer and creates a much smoother finish. Once you have removed all chunks that need to be gone get rid of the debris by place a vacuuming in the hole, then move on to applying a PVA mix so that it gives it the highest chance to bond with the existing wall. Next, mix the plaster well so it’s not too runny and apply 2 to 3 mm on the right area. once you have done that it’ll start to dry then scratch in the diagonal lines ready for when you put another coat on so it bonds together.
