How to Repair Holes in Concrete Floors
More in Floors
Here's How It's Done:
If only a small area is damaged, patch the hole only and level it off. For large holes, patch with a strong mortar mix before applying self-leveling compound.
Remove Dust and Debris
Dust out any loose material or debris from the hole using a dusting brush.
Dampen the Hole
Dampen the hole with some glue solution made up of four parts water to one part glue.
Add Mortar
Once the glue is tacky, press some mortar into the hole and use a gauging trowel to smooth it over.
Concrete Floor Solutions
- It is possible to improve a rough floor surface by adding a self-levelling compound to fill in cracks and gaps.
- After removing an old floor covering, such as cork tiles, use floor scrapers and commercial solutions to remove adhesive remains and bitumen-based products before laying a new floor covering. Otherwise, most self-leveling materials laid over a bitumen base will fail to adhere properly and may cause further problems.
- To protect a new concrete floor, seal it with a concrete sealer.
