As the warm weather arrives, many of us start thinking about home improvement projects, such as painting or making minor repairs. Before applying a new coat of paint, it is essential to fix any imperfections, such as chips or holes in the walls. In this post we explain how to use putty properly depending on the type of repair you need to make.

How to use putty according to the type of repair

Repairing holes in the wall:

If you need to fill a hole in the wall, it is best to use a tube of putty. An easy-to-use option is the ready-to-use RATIO paste putty. This putty is ideal for both interiors and exteriors and dries in just 15 minutes, allowing for quick sanding.

Steps to fill the hole:

1. Clean the area of the hole well to remove dust or dirt.

2. Knead the tube of putty, cut the nozzle and apply directly to the hole.

3. Use a spatula to remove the excess and smooth the surface.

4. If the putty shrinks as it dries, repeat the process to completely fill the hole.

Repairing chipped walls:

For chipped walls on interior walls, it is important to choose a putty that will not crack when dry. RATIO putty is perfect for these cases, as it adheres very well to porous surfaces and is easy to apply.

Steps to repair a chip:

1. Clean the affected surface.

2. Apply the putty with a spatula directly onto the chip.

3. Smooth the putty as you apply it, ensuring an even finish.

Covering small cracks

To cover small cracks on interior walls, we recommend using a fiberglass crack-covering tape, which offers high adhesive power and will serve as a base for the putty.

Steps to repair a crack:

1. Clean the crack, removing any loose material.

2. Place the crack-sealing tape along the crack.

3. Apply a powder putty diluted with water on the tape, smoothing it with a spatula.

4. Sand the surface once dry to make it ready for painting.

Repairing dents on lacquered surfaces

For dents on lacquered surfaces or those exposed to moisture, use a putty suitable for indoor and outdoor use. RATIO repair putty is perfect for surfaces exposed to moisture, as it offers a strong and durable finish.

Steps to repair lacquered surfaces:

1. Clean the affected area well.

2. Apply the putty with a putty knife, straight from the container.

3. Smooth the putty to achieve a smooth, even finish.

Now that you know how to use each type of putty depending on the repair you need, you're ready to start fixing those small imperfections at home. With these simple steps, your walls will be in perfect condition in no time. Let's get to work!
