Getting rid of unsightly holes on your wall can seem like a daunting task, but it can be done with relative ease with the right tools and know-how.
In this article, I’ll introduce you to various ways to repair dry holes in your walls and have it looking sparkling again.
We’ll start with the simplest and work our way up to the complex ones.
Small Screw Holes
This is by far the easiest fix for wall holes.
To start, use the filler knife to clean off the debris on the hole, so the filler compound will have a good surface to stick to.
Then use a clean filler knife to apply the filler compound to the hole. It's not a problem if the compound bulges out a bit when applied. Once it's dry, you can sand it down to shape with Sanding Pads.
Doorknob size holes to 5-inch dents and holes
There are two approaches to cover wall holes that are up to 5 inches large. The first method is to use an Adhesive Mesh Patch to cover the hole. The mesh patch should provide a reasonable solid surface to apply filler compounds like Polyfilla. Then you can work the filler with a Trowel to get a smooth surface.
The second way of doing this is called a California patch. You'll need a piece of plasterboard for this.
Unfortunately, Amazon doesn't do small pieces at the time of writing this. So your best bet is to check out your local hardware store. They are more likely to do smaller pieces at a reasonable price.
To get started with a California patch, you’ll first need to Mark out a square covering the hole. Then use a Jab Saw to cut out the plasterboard ready to fit a new piece.
With the new piece of plasterboard, create a square that will fit inside the hole but has one side where the paper is 2 inches bigger than the hole. This will act as a lip that will stick on the wall with the compound. This can be achieved using a Trimming Knife. Just run the knife at the backside of the plasterboard following the size of the square you created; then peel off the excess core of the plasterboard, leaving you with a square and some paper flaps.
Next, you will need to add a filler compound like Polyfilla. It will act as the glue for the patch. Use the Filler Knife to remove any excess compound and air bubble from the hole's edge and leave it to dry. Then you sand and paint to complete the project.
Above 5 inch dents and holes
To start, you will need to mark out a square covering the hole. Then using a Polyfilla, cut out the plasterboard ready to fit a new piece.
Fit pieces of wood inside the hole. They will act as bases for the new piece of plasterboard. You should make the wood slightly longer than the hole so that it can be screwed to the existing plasterboard.
Finally, screw the new piece of plasterboard to cover the hole. Then use filler compound to cover any gaps. Once it dries, sand to level and paint to complete the project.
