Water-Based PU Bituminous Waterproofing Membrane
Pentens T-100 is a single component which is newly developed polymer of MMA, natural rubber, and polyurethane combines with the reaction with asphalt and then being modified and further emulsified to form elastic waterproof membrane.
To provide a better water and vapor-proof in complicating application surface compare to membrane-type and ensure better integrity between applied surfaces and waterproofing coating.
Areas of application include:
Floor slabs, Suspended floors, Terraces and balconies, Patios, Bathrooms, RC gutters and planter boxes, Swimming pools, Water tanks, Basements and fountains, Retaining walls
All the surfaces must be clean, free from grease, oil, laitance, and remove all the dirt and contaminants, which might affect adhesion. The impurity outside the structure body should be cleaned thoroughly.
Any crack or water leakage area should be pre-treated and reinforced with Pentens Repair System (for more detail, please refer to our Technical Department) before the waterproofing.
For some difficult areas, such as the position of cracks, secondary joint, right angle of wall and the boundary shall be strengthened first with one layer of Pentens T-100.
Generally it is not required but for smoother application, not more than 1kg of clean water can be added into 20kg of Pentens T-100.
When used as a sand mortar, the amount of sand added to Pentens T-100 will determine the plasticity of the mortar and the hardness of the set material.
Substrate should be primed with a 1:3 mixture of Pentens T-007 and water. Brush on at the approximate rate of 0.3kg/m2.
On areas exposed hot drying winds. 2 to 3 thin coats of paint may be more successful than 1 thick coat. For indoor areas, it is recommended that allow approximately 30 minutes or after the primer becomes tacky then apply T-100.
With brush, roller, or spray method apply the first coat of Pentens T-100 on the application surface. The first coat should be applied in one direction only. If possible the second coat should be applied at right angles to the first. Leave to cure for approximately 8 hours before applying second coat.
-Bathroom and kitchen: 1KG/M2 2 coats.
-Roof, planter box, balcony, water tank and basement: 1.5KG/M2 2 coats.
For optimum performance, Pentens T-100 should be allowed to cure for 24 hours before the finishing concrete, tiles etc and during this time precautions must be taken in order to prevent damaging to the coating.
The best method to assure good penetration of the first coat into the surface is by application with a nap roller. The succeeding coats may be spray or roller applied.
Tools and equipment just can be clean with clean water immediately after use.
Impervious gloves and barrier cream should be used when handling these products. Eye protection should be worn. In case of contact with eyes, wash thoroughly with plenty of water and seek medical advice if symptoms persist. If contact with skin occurs, it must be removed before curing takes place. Wash off with an industrial skin clearer followed by plenty of soap and water. Do not use solvent. Ensure adequate ventilation when using these products.
1. Thoroughly agitate contents before use.
2. Minimum ambient and substrate temperature is 5°C.
3. Never apply more than 1 kg/m2 of Pentens T-100 in one single layer.
4. Apply only to clean, sound substrates where surfaces should be well dampened but free of surface water and leaks.
- Ease of application directly from container.
- High elasticity.
- Superb adhesive strength.
- Can apply directly on damp or wet surfaces.
- The softening point will not be further softened due.
- To hot and humid climate in tropical countries.
- Resistant to any bubbling or side osmosis
- Phenomenon even submerge in water for a long time.
