How to Quickly Repair Cracks and Crevices in Walls

Apply the grout a little at a time, until the inside of the crack is completely filled.

Using a spatula, spread the coulis over the surface and smooth it as much as possible, then wait 24-48 hours for it to dry completely.

After the pre-set time, smooth the sandpaper. Finally, dust off the excess powder and then apply one or two coats of paint in the same color as the wall.
