concrete deep crack filler 500g

A 500g concrete crack repair package is a ready-to-use, quick-drying, and waterproof sealant or putty designed to fill gaps in driveways, floors, and walls. Most formulas feature gray coloring to match standard masonry, self-leveling or paste options, and a 24-hour full curing time.

Surface Preparation

• Clean out debris: Use a wire brush, screwdriver, or scraper to dig out loose dirt, old caulk, and crumbling edges from the crack.
• Remove dust: Vacuum or blow out remaining fine particles so the adhesive sticks well.
• Dry completely: Ensure the crack is totally free of moisture unless the specific product instructions state otherwise.
  
  Concrete crack repair products can be used on a wide variety of indoor and outdoor masonry surfaces, depending on whether the formula is self-leveling (for floors) or a thick paste (for walls).
