How To Fix Holes In Concrete Walls Inside?

Small holes in concrete walls can be easily fixed using a putty knife and an all-purpose wall filler like Everbuild All Purpose Ready Mixed Filler. To repair small cracks or holes in cinder block walls, clean the area and mix quick-setting cement and pour it. Basement wall crack repairs can fall into two categories: non-structural and structural repairs. Non-structural repairs focus on rehabbing the appearance of the concrete wall and preventing moisture. Timbermate 500g Concremate Expanding Cement is a stronger option than plaster filler, but it should be avoided drilling. Concrete patch in a tube can be used to stick it in the hole and squeeze until it comes out. UNi-PRO 500g Multi Purpose Interior Filler can be applied to fill the hole and then a skim coat over the area with a damp/wet sponge. Cracks can be repaired with cement patching material, while corrosion holes require something more substantial, like epoxy putty or steel mesh reinforcement.

To prepare the area for fixing holes in concrete walls, start by cleaning the hole and removing any debris. Mix quick-setting cement and pour it over the area. A damp/wet sponge can be used to smooth out concrete patches into the surrounding material, making it easier to apply. Watco Concrex Vertical, Bio-D, Tack Coat Trowels, and Floats are recommended tools for repairing holes in concrete walls and pillars.
