Sikafloor -31 NA PurCem is state-of-the-art, high-build coating with a matte finish, based upon pthalate-free, water dispersed polyurethane/cement and aggregate technology applied at 10 mils per coat. It is designed as a standalone coating for concrete, as primer/sealer for Sikafloor -24 NA PurCem and as a top coat for Sikafloor PurCem broadcast textured systems. It is an economical and versatile material that improves adhesion and mitigates outgassing of substrates as a primer, while providing excellent chemical resistance properties and very good durability against abrasion and mechanical damage. Sikafloor -31 NA PurCem represents superior polyurethane/cement technology, combining easier application, resistance to blistering and improved performance.

• Can be applied onto 7 to 10 day old concrete after adequate preparation and where substrate has tensile bond strength in excess of 1.5 MPa (218 psi).
• Economical and easy installation requiring less labour to install than traditional Sikafloor PurCem materials.
• Versatile material suitable for application as a primer, standalone coating and top coat for other PurCem systems.
