In addition to concrete floor joint repair measures, every day wear and tear on a concrete floor can cause the surface to chip and crumble. This effectively means your concrete surface breaks into small pieces that create pock marks, nooks and crannies, deterioration, etc. However, surface spalling can be repaired using these steps.
Tools & Equipment
- For structural epoxy mortar, use Metzger/McGuire Armor-Hard
- For rapid access, use Metzger/McGuire Armor-Hard Extreme
- If you’re working in a freezer or cooler, use Metzger/McGuire Spal-Pro 2000 or Armor-Hard Extreme
Step 1. Make cuts with blade or chip out section at outer edges of spalling with a chisel to at least ¾-inch deep, creating a vertical edge.
Step 2. Grind out or chisel any spots of the floor with the work area that are higher than the level of the edges. Vacuum, brush and wipe the area clean with a rag.
Step 3. Overfill the area with repair material and trowel smooth and slightly higher than the floor surface.
Step 4. Once repair material is cured, remove any overfill to create a smooth, flush surface by grinding with a high quality polishing pad.
