Triblock P 5kg Special Primer

Triblock P is used as a waterproofing treatment for damp substrates, and especially:

• old ceramic or terrazzo floor dressings on substrates with excessive residual humidity;

• highly-compact cementitious substrates with a residual humidity content higher than the level recommended for laying wooden, resilient and resin floors;

• treating damp concrete surfaces before applying protective and anti-corrosion epoxy products, or polyurethane dressing systems which are impermeable to water vapour;

• dressing concrete channels, drains and pipe-work; and by adding 0.25 Quartz o 0.5 Quartz sand at a ratio of 1 : 0.5 for smoothing over uneven surfaces.

TECHNICAL CHARACTERISTICS Triblock P is a three-component epoxy-cementitious system which has the capacity of reticulating on damp surfaces, even if they are very smooth (ceramic tiles, porcelain, marble, etc.), and of forming a compact layer suitable for laying parquet, PVC, linoleum, ceramic, epoxy and polyurethane dressing coats and cementitious smoothing layers. It is manufactured according to a formula developed in MAPEI’s own research laboratories. The product may be used as it is, by diluting it accordingly with water, or by adding 0.25 Quartz or 0.5 Quartz sand, to obtain a smoothing mortar for use on uneven concrete surfaces when a high mechanical strength of the dressing material is required.
