How to easily patch holes in a wall

Do you have holes in your wall? Here's how to fix them

If there's a hole in your wall that bothers you and you never find the right time to fix it, now is the time to act. Holes in walls can have different causes and, depending on the size and depth, you'll need different solutions. Whether you're preparing the wall for painting, wallpapering or simply leaving it in perfect condition, we'll explain how to cover those holes and get your wall looking good again.

Step 1: Prepare the hole

Before you start covering the hole, it's important to prepare it well. If the hole is very small, we recommend making it a little bigger with the help of a triangular spatula. This will allow the putty to adhere better and properly cover the damaged area, especially if the edge of the hole is cracked. Slightly widening the hole ensures that you completely cover any fractures that may extend.

Step 2: Clean the Area

Once the hole is prepared, it's essential to thoroughly clean the affected area. Remove any dust and debris that may have been left in the hole, as failure to do so may result in the putty not adhering properly. Use a clean rag or vacuum to thoroughly clean the area, which will ensure a better finish when applying the putty.

Step 3: Apply the Putty

Now it's time to fill the hole with putty. For this step, we recommend using a putty that doesn't shrink when it dries, so you don't have to repeat the process. Using a medium-sized putty knife, take a small amount of putty (about the size of a hazelnut) and apply it to the hole. Make sure to smooth out the putty with the putty knife so that it is as even as possible with the surface of the wall. Then, let the putty dry according to the time indicated by the manufacturer.

Step 4: Sand and paint

Once the putty is completely dry, it is time to sand. This step is crucial to achieve a completely smooth surface. Use appropriate sandpaper, depending on the size of the area to be sanded. If the hole is large, an electric mouse sander will be the best option, while for smaller areas a sanding block will suffice. If when sanding you notice that the hole is not completely covered, apply another layer of putty, let it dry and sand again.

Finally, wipe off the dust with a rag and proceed to paint the repaired area with the same color as the wall. Make sure to protect the floor and furniture well before you start painting.

What if the hole is deeper?

When the holes in the wall are deeper than 5 millimetres, you will need a specific putty that will cover the thickness of the damage well, without cracking or shrinking when drying. In these cases, it is advisable to use a putty with a higher density that guarantees a durable and resistant finish.

Done! Now all that's left to do is enjoy your wall as good as new

With these simple steps, you already have everything you need to cover the holes in the wall and leave it as good as new. It is a simple process that you can do yourself in a short time and without major complications. Go ahead and repair those little imperfections and renew your spaces!
