Larsen Acrylic Primer | Ready to Use Primer for Tiling, Screeding & Porous Substrates

Acrylic Primer from Larsen Building Products is a high-performance ready-to-use acrylic primer developed to improve adhesion and surface preparation before tiling, screeding, and flooring installations. Designed for use on porous and difficult substrates, this water-based polymer emulsion helps stabilise surfaces while enhancing the bond strength of cement-based adhesives and levelling compounds.

Ideal for sealing gypsum plasters and screeds prior to the application of cement-based tile adhesives, Acrylic Primer reduces substrate porosity and promotes improved adhesion across a wide range of internal flooring and wall preparation projects. The coloured formulation provides clear visual indication during application, helping ensure consistent coverage.

Suitable for use either neat for sealing highly porous substrates or diluted 1:1 with clean water for general priming applications, Larsen Acrylic Primer delivers versatile professional performance for domestic and commercial installations.
