Bostik ULTRA MULTIPRIME A530 – General Purpose Primer

Bostik Ultra Multiprime A530 is a high-performance, general-purpose primer designed to prepare porous surfaces prior to tiling and waterproofing. Its advanced acrylic formulation penetrates and seals substrates, creating a consistent surface that enhances adhesion and overall system performance.

Ideal for use on surfaces such as concrete, render, fibre cement, plasterboard, and timber, A530 helps reduce surface dusting and minimises pin-holing in membranes. It is fully compatible with Bostik tile adhesives and most waterproofing systems, making it a reliable choice for both residential and commercial applications.

Suitable for internal and external use, this easy-to-apply primer ensures a strong, durable bond—helping you achieve professional results every time.
