Overview

KingProof C25 is a two-component, acrylic-modified
cementitious coating that requires only on-site mixing to
form an ideal product for waterproofing and resurfacing
concrete, masonry and most other construction
substrates. Simply applied by stiff brush, roller or trowel, it
forms a waterproof, flexible coating that provides an
effective barrier to waterborne salts and atmospheric
gases. Once applied, it forms a hard-wearing, seamless,
waterproof membrane suitable for roofs and foundation
protection.
