Boscoseal BLOCK A550 (RC2) is a high-performance, single-component acrylic waterproofing coating designed to create a durable, seamless, and flexible waterproofing membrane. Once cured, it forms a tough elastic film capable of accommodating minor structural movement, thermal expansion, and shrinkage cracks in the substrate.
This advanced acrylic formulation provides excellent adhesion to concrete, cement mortars, blockwork, and various mineral-based substrates, ensuring long-term waterproofing protection.
Boscoseal BLOCK A550 (RC2) is suitable for a wide range of internal and external waterproofing applications, including retaining walls, foundations, balconies, façades, wet areas, and any surface requiring a durable moisture barrier. Its single-component, ready-to-use nature makes it easy to apply without mixing, offering reliable waterproofing performance for both professional contractors and building maintenance work.
