If you’re new to plastering, there are a few problems you might encounter. See this here.
Here are 14 of the most common ones:
1. Not Enough Plaster On The Wall
This is probably the most common problem for new plasterers. You need to make sure you apply enough plaster to the wall so that it’s evenly covered. Otherwise, you’ll end up with patchy areas where the plaster isn’t thick enough.
2. Applying Too Much Plaster
On the other hand, applying too much plaster can also be a problem. This can happen if you try to spread the plaster too thin or if you don’t smooth it out properly. Too much plaster on the wall can make it difficult to sand down later on.
3. Not Using A Primer
If you’re not using a primer, you’re likely to encounter problems with the plaster not sticking to the wall properly. This can cause it to crack and flake off, leaving patches of the bare wall behind.
4. Applying The Plaster Too Thick In One Go
Another common mistake is applying the plaster too thick. This can make it difficult to level out and can also lead to cracks forming as the plaster dries.
5. Not Waiting For The Plaster To Dry Before Sanding
If you try to sand down the plaster before it’s completely dry, you’ll create a lot of dust and potentially damage the surface of the wall. It’s important to wait until the plaster is completely dry before sanding it down.
6. Not Using Enough Joint Compounds
If you’re not using enough joint compounds, you’ll find that the plaster doesn’t adhere properly to the wall and can start to crumble. This can create gaps and holes in the plaster surface.
7. Applying Joint Compound Too Thick
Just like with plaster, applying joint compound too thick can also be a problem. This can make it difficult to spread evenly and can cause it to crack as it dries.
8. Not Using A Wet Sponge When Sanding
When you’re sanding down the joint compound, you should always use a wet sponge. This will help to avoid creating too much dust and will also help to keep the joint compound from drying out too quickly.
9. Apply Paint Before The Joint Compound Is Completely Dry
If you try to paint over the joint compound before it’s completely dry, you’ll find that the paint doesn’t adhere properly and can start to flake off. It’s important to wait until the joint compound is completely dry before painting over it.
10. Not Using A Sealer
If you don’t use a sealer, you’ll find that the plaster can start to absorb moisture from the air. This can cause it to expand and contract, which can lead to cracks forming.
11. Not Enough Joint Compound.
When you’re plastering, you need to make sure there’s enough joint compound to cover the entire surface. Otherwise, you’ll end up with patches of a bare wall.
12. Dents In The Plaster
This can be caused by using too much pressure when applying the plaster or by not allowing the plaster to dry completely before sanding. Be sure to apply the plaster evenly and give it plenty of time to dry.
13. Wallpaper Not Adhering To The Surface
This can be caused by not allowing the plaster to dry completely before wallpapering. Make sure you give the plaster plenty of time to dry before wallpapering.
14. Cracks In The Paint Or Wallpaper
This can be caused by an incorrect mixing of the plaster or poor application. Make sure you mix the plaster correctly and apply it evenly.
These are just some of the most common problems you’ll encounter when plastering. By following these tips, you can avoid them and ensure a smooth, professional finish.
