5 painting tricks to remove wall defects

Detect wall damage

The first thing we must do is to detect all the damages to the walls. For this, we will turn off all the lights of the room in which we are, we will close the blinds. So that no light enters, and with a flashlight or lamp as the of the image, we are lighting up parallel to the wall. In this way, we can find the flaws quickly and easily. When we find one, we can mark it with a bodybuilder’s tape.

Cover small holes and cracks

Fill the small holes with putty, using a spatula, spreading it well on the wall. Smooth the putty with the spatula. The objective is to make the connection between the wall and the fill hole as continuous as possible. Using a damp cloth, clean any remaining putty that may have been left on the wall, around the hole.

You have to apply several layers, and let it dry. To know exactly the drying times, look at the instructions of the putty or joint compound.

For the small cracks in the wall, we can follow the same execution as with the holes, but first, we can pass the tip of a spatula along the entire path of the crack, to clean it, and that the putty sits correctly.

Large holes in plaster walls

To fix a large hole, you will have to cut a piece of wall on each side of the hole. In this way, you can attach a new piece of plasterboard.

Cut along the damaged contour of the hole with a drywall saw and remove the remaining pieces. Next, make a cut with a cutter in the center of the crossbar. In this way, you can join the new piece of plasterboard to the crossbar.

Cut another piece of plasterboard the size of the hole you’ve made.

Apply a thin layer of joint compound to the joint between the hole and the wall.

Place the plasterboard tape over the entire contour of the hole. You must press the tape to smooth it completely on the putty and scrape the excess putty with the spatula or the trowel.

Apply putty or joint compound forming a straight line along the used tape and let it dry 12 hours.

Pass a sandpaper or a 120-grit sandpaper sponge. Sand the putty until the surface of the filler is smooth and even.

Prepare and paint the surface of the repaired hole so that it does not clash with the rest of the wall. In the case of large areas, such as entire walls of plasterboard and rooms, it is advisable to prepare the surface very well to achieve a lasting and uniform result. Preparing the surface well, in addition, will help you save money on the paint finish.

Wall in poor condition or with ancient stains of moisture: plastering the wall again

If there are parts of the wall in very bad condition, with bags, or in those places where there has been a humidity, it must be plastered again. To do this, remove all the old plaster with a spatula and in poor condition with a spatula.

Then, apply a primer with a brush in the area and let it dry.

Then we apply putty and plastering, with a wide spatula, to match the rest of the wall.

Rasp the surface with a fine sandpaper and remove the dust. Finally, we give a second layer of putty for laying and plaster. After drying the wall, and with a fine sandpaper, and remove the dust again.

After this, we apply a layer of primer to the wall and let it dry. And we have repaired the wall and ready to paint!

Remove the glue

The mirrors, or different elements, can be adhered to the wall with glues. Very much, when you see these, do not try to pull them to remove them, since you will also take the plaster layer and make a mess on the wall. Instead, cut around the perimeter of the glue with a cutter or knife.
