SCALING:

Primary Causes:

• Low air content

•Freezing and thawing of immature Concrete

•Floating in bleed water

•Hard troweling air-entrained concrete

•Aggressive de-icing salts

•Insufficient curing

•Lack of sealing/Moisture proofing

The deterioration of the surface of concrete.

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.
