&MAPE!Three-component epoxy-cementitiousprimer for damp substrates WHERE TO USE 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. RECOMMENDATIONS • Do not apply Triblock P directly on: - surfaces with free-standing water; - dusty, flaky, irregular surfaces with bleeding; - anhydrite or gypsum-based substrates; - old, cementitious or gypsum-based smoothing layers. • Do not apply Triblock P on cracks which are subject to movement, as the product is rigid and may also crack. APPLICATION PROCEDURE Preparation of the substrate The cementitious substrate must be solid, mechanically strong, perfectly clean, free of crumbling parts and standing water. It must be sufficiently cured and have completed most of the shrinkage phase. Preparation may be carried out by sand-blasting, hydro sand-blasting, sanding, shot-blasting or grinding, according to the condition of the substrate and the successive applications. Old ceramic and terrazzo floors must be well-bonded to the substrate and not have residual materials on the surface, such as wax, oil, grease, etc.

If the surface to be treated is particularly uneven, it must be repaired and levelled off prior to treatment with a suitable damp-resistant product, or with Triblock P mixed with 0.25 Quartz or 0.5 Quartz sand. Preparation of the product Triblock P is made up of three components, of which two are liquids and one is a powder. To prepare the product, mix component A with component B until a homogenous, uniform-coloured, mix is obtained. Then slowly add component C (powder) while mixing until a smooth, lump-free paste is obtained. The mixing ratio between the three components is 12 : 38 : 50...
