Long lasting basement moisture barrier
- Effective waterproof polymer cement: Apply this TEC7 coating to seal damp basement walls and floors against water pressure and salt efflorescence.
- Elastic crack bridging formulation: You maintain a durable protective layer because the flexible composition accommodates subtle structural movements.
- Flexible direct surface finishing: Once fully cured, you can immediately plaster, tile, or paint directly over the coated surface.
With the TEC7 WP7-501 polymer cement coating, you reliably protect damp basement walls and floors against water pressure and salt efflorescence. This elastic sealing barrier bridges fine structural cracks, effectively preventing crumbling plaster, mold growth, and musty odors in your cellar. One 10 kg and 1 l kit covers 5 to 6 m² of wall area in the required two coats of approximately 1 mm applied with a brush. It also serves as a dependable waterproof barrier for water reservoirs, ponds, and concrete bases. Once fully cured, you can immediately paint, tile, or plaster directly onto the breathable surface.
Product description
POLYMER CEMENT COATING
- 100% waterproof
- Simple application
- Waterproof and salt-resistant from 2 mm
- Also on wet walls
- A hard but elastic coating for damp basement walls, basement floors and utility rooms
- Can be tiled, plastered and overpainted
- Can be applied by brush after mixing with water, with perfect adhesion to porous materials and fast curing
- Resistant to salts and water pressure on stable, receptive substrates
- Crack bridging ability and resistant to permanent immersion
- Prevention or strong reduction of salt efflorescence, waterproof but vapour permeable
Instructions
- Remove as much old paint and loose plaster as possible
- Dilute sealant primer 1:1 with clean water and apply saturated with the spray pump on clean, receptive and stable substrates
- Mix the required amount of polymer cement for the first coat (1 kg per 1.2 m²) with pure water. Mixing ratio 400 ml water per kg
- Mix with a slow-running mixer (500 rpm) until a thick liquid, lump-free mass is obtained and allow to rest for 2 minutes. Stir again before use. The mixture is workable for 35 to 45 minutes, depending on the ambient temperature
- When stiffening up in the pot, never add water to respect the mixing ratio: so mix as much product as you can apply within the processing time at most
- Apply the first coat of +/- 1 mm with a broad, stiff brush on the still wet primer
- Allow to dry for 3 to 5 hours before applying the second layer (the first should feel hardened)
- Moisten the first layer with water using a sprayer and apply the second layer of +/- 1 mm at right angles to the direction of brushing the first layer
- Clean material and spilt product immediately with clean water. Can only be removed mechanically after curing
- Complete curing after 7 to 14 days, depending on temperature. Air humidity during this period: 50 to 80 %.
- Ensure ventilation to avoid condensation. Do not use a construction dryer or dehumidifier in the first month after application
- Can be repainted after curing with breathable paint
- Consumption: 1 10 kg bag for 6 m² (2 mm thick in 2 layers on a plain wall)
