Triblock P is a three-component epoxy-cementitious system designed to adhere to damp surfaces, including smooth materials like ceramic tiles, porcelain, and marble. This product creates a durable layer suitable for various floor coverings, such as parquet, PVC, linoleum, ceramic, epoxy, polyurethane, and cementitious smoothing layers. Manufactured using a formula developed in MAPEI’s research laboratories, Triblock P can be applied directly or diluted with water. Additionally, by incorporating 0.25 or 0.5 Quartz sand, it can be transformed into a smoothing mortar ideal for uneven concrete surfaces requiring high mechanical strength.
Key Points
Three-Component System: Triblock P is an epoxy-cementitious system that effectively adheres to damp surfaces.
Versatile Applications: It is suitable for laying a variety of floor coverings, including parquet, PVC, linoleum, and ceramic tiles.
Customizable Mixing: The product can be used as is or diluted with water, with the option to add Quartz sand for enhanced performance.
High Mechanical Strength: It is particularly effective for smoothing uneven concrete surfaces that require high strength.
5 kg kits (A + B + C): component A: 0.6 kg; component B: 1.9 kg; component C: 2.5 kg.

Triblock P is utilized as a waterproofing treatment for damp substrates, particularly in the following scenarios: it effectively addresses old ceramic or terrazzo floor coverings on substrates with excessive residual humidity; it is suitable for highly compact cementitious substrates with moisture levels exceeding the recommended limits for installing wooden, resilient, and resin floors; it is also used to treat damp concrete surfaces prior to the application of protective and anti-corrosion epoxy products or polyurethane systems that are impermeable to water vapor; in addition, it is ideal for dressing concrete channels, drains, and pipework. Furthermore, by incorporating 0.25 or 0.5 Quartz sand at a ratio of 1:0.5, it can be used for smoothing uneven surfaces.
Preparation of the Substrate
The cementitious substrate must be solid, mechanically strong, and completely clean, free from crumbling parts and standing water. It should be sufficiently cured and have completed most of the shrinkage phase. Preparation can be performed through sandblasting, hydro sand-blasting, sanding, shot-blasting, or grinding, depending on the substrate’s condition and the subsequent applications. Old ceramic and terrazzo floors should be well bonded to the substrate and free from residual materials such as wax, oil, or grease. If the surface is particularly uneven, it should be repaired and levelled before treatment with a suitable damp-resistant product or with Triblock P mixed with 0.25 or 0.5 Quartz sand.
TRIBLOCK P
Three-component, epoxy-cementitious primer for damp substrates.
Preparation of the Product
Triblock P consists of three components: two liquids and one powder. To prepare the product, mix component A with component B until a homogeneous, uniform-coloured mixture is achieved. Slowly add component C (powder) while mixing until a smooth, lump-free paste is obtained. The mixing ratio for the three components is 12:38:50 by weight. If you do not need the entire contents, ensure strict adherence to the mixing ratios to avoid poor catalysis of the product. A low-speed drill is recommended for mixing to prevent overheating, which can reduce workability and cause air entrapment. Depending on the application method, water can be added as follows: 5-10% for brush application, 10-15% for roller application, and a maximum of 20% for spraying. For grouting, smoothing, repairing surface defects, or filling cracks not subject to movement, mix Triblock P with a maximum of 5% water and a ratio of 1:0.5 of dry 0.25 or 0.5 Quartz to create a mortar suitable for trowel application. Once prepared, Triblock P remains workable for 30-40 minutes at +23°C, so it must be applied within this timeframe.
Application of the Product
Apply Triblock P, diluted as required, to the surface in two coats using a brush, roller, or airless spray system. If applied on particularly hot substrates, it may be beneficial to dampen the substrate beforehand. The product should be applied in two criss-cross coats, ensuring each coat is even, with the second coat applied approximately 4-6 hours after the first. For grouting, smoothing, repairing surface defects, and filling cracks not subject to movement, use a trowel mixed with 0.25 or 0.5 Quartz. If there is a high level of humidity in the substrate, an additional coat of Triblock P diluted with 5-10% water may be necessary after smoothing. Small cracks should be opened into a “V” shape, and any dust or loose material removed. Treat these with a coat of Triblock P diluted with 5-10% water and fill with Triblock P mixed at a 1:0.5 ratio of 0.25 or 0.5 Quartz. The product should not be used if the surrounding temperature or substrate temperature is below +5°C, and floors or smoothing compounds must be applied within 7 days.
Laying Wooden or Resilient Floors
After approximately 24 hours (at +23°C and 50% relative humidity), the floor can be installed using a two-component epoxy-polyurethane adhesive, single-component polyurethane adhesive (such as Ultrabond P902 2K, Lignobond, Ultrabond P990 1K, or Adesilex G19), or a silylated polymer-based adhesive (like Ultrabond Eco S940 1K).
Laying Protective Epoxy and Polyurethane Dressing Materials
Triblock P can be painted over after about 24 hours. The hardened layer may be covered with any type of epoxy or polyurethane dressing product, with or without solvents. If necessary, apply the specific primer beforehand, as indicated in the relevant Technical Data Sheets.
