3 P r e m i r P Two-component polyurethane primer in solvent WHERE TO USE Primer P3 is a two-component primer in solvent used to promote adhesion of polyurethane finishing products to membranes from the Purtop line and to promote adhesion of Purtop membranes to existing bitumen membranes. Primer P3 is also used as an adhesion promoter for Mapeslope levelling cementitious mortar when applied on bitumen membranes. TECHNICAL CHARACTERISTICS Primer P3 is a primer in solvent according to a formula developed in the MAPEI research laboratories and is compatible with waterproofing membranes from the Purtop line and Mapeslope levelling cementitious mortar. Advantages • Low viscosity. • Reduced covering times. • Easy to apply. APPLICATION PROCEDURE Preparation of the substrate The surface to be treated must be clean and dry and have no traces of loose material, dust, dirt, grease, oil or any other material or substance that could affect adhesion of the product. When used to promote ad

hesion to bitumen membranes proceed as follows. Clean the bitumen membrane to remove any substance or material that could affect adhesion of the waterproofing system. The membrane must be perfectly dry inspect the surface and any damage to the membrane, such as blisters, tears or detached areas, must be repaired before applying the primer. Preparation and application of the product Primer P3 is a polyurethane primer made up of two pre-dosed components. To prepare the product, mix each of the two components for a few minutes and then pour component B into the container of component A. Mix the two components together with an electric mixer at low-speed to thoroughly blend them together (at least 3-4 minutes). To reduce overlaying times for the product to around 4 hours add 1% in weight of PU Catalyst (catalyst for polyurethane products) and mix for several minutes. Apply an even coat of Primer P3 with a brush, roller or by spray (for application by spray, bear in mind the short pot-life
