ALCOLIN Exterior Crackfiller is an off-white, cement-based repair compound designed for filling, sealing, and weatherproofing cracks in masonry and concrete surfaces. Its anti-slump, non-sag formula makes it ideal for vertical repairs, while special additives improve workability and water resistance.
The product offers low shrinkage across a wide crack width range and dries to a durable finish that can be sanded and painted to blend seamlessly with surrounding surfaces.
