Surface Preparation:• The suface to be patched should have a rough profile.
• Expose at least the top portion of the coarse aggregate.
• The surface to be patched must be clean, hard and dense.
• Pre-soak all surfaces with water for a minimum of 2 hours . just before placement.
• At the time of placement the surface should be saturated . and damp, without standing water present.
• If a bonding agent is used, follow the manufacturer’s . recommendation for surface moisture content.
• For best results choose one of L&M’s bonding agents.
