Triblock P
Three-component epoxy-cementitious primer for damp substrates.
Three-component, epoxy-cementitious primer for damp substrates
- Triblock P is used as a waterproofing treatment for damp substrates
- 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
- By adding 0.25 Quartz o 0.5 Quartz sand at a ratio of 1 : 0.5 for smoothing over uneven surfaces
- Consumption
- 250-500 g/m² per coat, two coats
- Pack we stock
- 5 kg
Coverage calculator
How much you need.
The arithmetic uses Mapei's published consumption for Triblock P and the pack sizes we stock. Set your own wastage allowance.
You need
x 5 kg kit (A + B + C)
- Data sheet quantity
- 10-12 kg
- With 10% wastage
- 11-13.2 kg
The figures behind it.
- 250-300 g/m² per coat on non-absorbent surfaces.
- 400-500 g/m² per coat on absorbent surfaces.
- 1.5 kg/m² per mm of thickness for smoothing applications.
The data sheet applies Triblock P in two criss-cross coats.
Consumption on site depends on the substrate, the tool and the applicator, which is why wastage is yours to set. The result is a quantity to plan and quote with, not a guarantee of coverage. Confirm the system against the current Mapei technical data sheet before ordering.
Application
Where it is used.
In Mapei's own words, from the technical data sheet.
- 01Triblock P is used as a waterproofing treatment for damp substrates
- 02Old ceramic or terrazzo floor dressings on substrates with excessive residual humidity
- 03Highly-compact cementitious substrates with a residual humidity content higher than the level recommended for laying wooden, resilient and resin floors
- 04Treating damp concrete surfaces before applying protective and anti-corrosion epoxy products, or polyurethane dressing systems which are impermeable to water vapour
- 05Dressing concrete channels, drains and pipe-work
- 06By adding 0.25 Quartz o 0.5 Quartz sand at a ratio of 1 : 0.5 for smoothing over uneven surfaces
Where it is not the right product.
- 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
- Do not use the product if the surrounding temperature or the temperature of the substrate is lower than +5°C
