How To Cover Holes In The Wall?

The appearance of cracks and holes in the walls is more common than we may think. These damages occur after a plumbing or electrical work, but also with the passage of time some deterioration can occur due to small accidental knocks.

Placing decorative elements and artwork on the walls is a good way to change the look of a space. However, we often dismiss the idea for fear of damaging the walls in the process. This is why it is worth learning how to fill holes in the wall, in order to make all the necessary modifications without doubting us.

The best product to cover holes in the walls


Plugging holes and other defects can make a big difference when repairing walls, which is why it is a very common practice in homes. Some years ago, plaster or plaster was used to cover holes, especially in ceilings made of this material. In that case, the powdered plaster had to be mixed with water to create a consistent mass and thus repair the problem areas.

Currently, there are many products that serve this purpose, some are ready to use and others are very easy to prepare, but it is important to know that each one has been manufactured for specific uses, according to the composition and properties. of the material , therefore, it is necessary to review the characteristics well before making the purchase.


In this sense, we can say that the putty to cover holes is the most practical solution to use on walls, since most of the cracks and holes that appear in houses are small and this product comes in minimal quantities, it is relatively cheap and it is ready to be used immediately.

The key to choosing a good putty is its ability to hold volume after drying time. Generally, the putty tends to shrink, therefore, once it dries, you have to reapply another layer and repeat the process as many times as necessary to completely cover the hole. However, if we choose a putty that does not decrease in size, the process is faster and easier, since we only have to apply once.


Step by step: plug a hole in the wall


If you are wondering how to plug a large hole in the wall, you should know that you need to buy a pot of putty that has an adequate amount depending on the damage to the wall. In extreme cases, it is preferable to fill a hole in the wall with cement, for this we must prepare a mortar with sand and water, so that we only have to use the putty for finishing.

However, here are a series of steps on how to plug a hole in the wall without cement, in case it is a minor repair job. For this DIY project we need a putty knife , fine-grit sandpaper, and a high-quality non-sagging putty.

Check the actual size of the hole


Both cracks and holes in the walls can fool the naked eye, since they sometimes seem small, but it is possible that a larger area has been affected. In this sense, it is best to check with the tip of the triangular spatula, to check the real magnitude of the damage to the wall .

In addition, although it may seem difficult to believe, a too small hole in the wall can be more difficult to cover, so it is advisable to open a little, making circles with the tip of the metal spatula. If it’s a crack, you can go all the way with the tool several times until you check for a deeper crack in the wall.

Clean the surface


Regardless of the type of putty you have, this product generally adheres better when the surface is completely clean, but the use of the spatula can generate excess dust, so it is necessary to clean with a dry brush . This step can be streamlined if you use a vacuum cleaner, in addition, this guarantees a deeper cleaning for a better fixation of the putty on the wall.


Apply putty


This is the most important part when repairing a hole in the wall. The first thing to mention at this point is that if you have powdered putty, you have to use 500 ml of water for every kilo and mix until you get a homogeneous mass. For this, it is not necessary to use a concrete mixer ( here you will find some purchase options ), since you can do it with the same spatula. If, on the other hand, you have bought ready-to-use putty, it is good to stir it well before applying.

On the other hand, it is advisable to add the putty in small quantities, to avoid excess and protrusions. In the case of cracks, it must be applied first in a perpendicular way and then along the fault, in order to fill in a uniform way.

Sand and paint


If when drying you notice that the putty has diminished, you just have to sand the surface a little, clean and apply a second coat . When it is completely dry, it must be sanded again to smooth. The best way to hide these types of repairs is to paint the entire wall, to avoid the difference between the new and old paint. However, in some cases it is enough to paint the repaired area.

As we can see, covering wall cracks can be quite simple if we use the right product, but for this it is important to take into account the type of surface to be repaired and the size of the hole.
