Mapei Plastimul Primer is a solvent free bitumen primer for evening out and improving bonding to substrates before applying a waterproofing product from the Mapei Plastimul range.

Best Uses

Mapei Plastimul Primer is best used to even out and improve bonding to the substrate before applying waterproofing products from the Plastimul range. Plastimul Primer is a single component, solvent-free bitumen emulsion with good workability properties. Plastimul Primer may be applied by brush or roller and is resistant to aggressive substances in the ground.

• Plastimul Primer dries quickly
• Plastimul Primer consolidates and improves bonding of Plastimul waterproofing treatments applied later
• Plastimul Primer is resistant to ageing and adheres to dry substrates
• Plastimul Primer may be applied both internally and externally

Mapei Plastimul Primer is ideal for substrates such as vibro-compressed concrete blocks, solid terracotta bricks, breeze blocks, cellular concrete blocks, lightened bricks and solid pumice bricks.

Application

Do not use for waterproofing without a successive application of products from the Plastimul range. Do not use for waterproofing structures with water in counter pressure. Do not lay on old screeds and layers of bitumen. Do not lay on substrates containing tar.

Before applying Mapei Plastimul Primer on substrates such as vibro-compressed concrete blocks, solid terracotta bricks, breeze blocks, cellular concrete blocks, lightened bricks and solid pumice bricks, make sure that the surface is perfectly clean, solid and sufficiently even. Carefully remove traces of installation mortar protruding from between the bricks or blocks. Grout any empty spaces in the joints using either Mapei Mapegrout Fast-Set, quick-setting fibre-reinforced cementitious mortar if waterproofing is required quickly, or Mapegrout Thixotropic, shrinkage compensated, fibre-reinforced mortar. Cavities and cracks deeper than 5 mm must be smoothed over with Mapegrout Fast-Set or with the chosen mortar.

As an alternative, if cavities are less than 5 mm deep, the surface may be smoothed over with a bitumen waterproofing product, to avoid entrapment and the formation of blisters. As an alternative, mortar made using sand and cement with added Planicrete, rubber for cementitious mixes latex. Create a fillet to blend in the foundations with the side walls using Mapegrout Fast-Set or Mapegrout Thixotropic.

Shake Plastimul Primer well in its own tub to make sure that it is perfectly homogenous. Apply using a brush or roller on dry surfaces in a single coat. The product dries in approximately 30 minutes.
