TechFin® 2K
Two Component Elastomeric Cementitious Waterproofing Coating System
TechFin® 2K is a two component elastomeric acrylic emulsion modified cementitious coating system incorporating a blend of cementitious powders combined with proprietary activating chemicals and high grade quality aggregate fillers with selected bonding agents.TechFin® 2K provides positive and negative water repellency against dampness and ground water as well as hydrostatic pressure. It can simply be applied by stiff brush, roller or trowel to obtain the desired thickness. The slurry coating forms a moisture barrier, significantly reducing the water absorption into dry surfaces, allowing moisture to migrate out of protected areas and avoiding moisture build up and dampness.
Features:
- Allows water vapour to escape from the structure.
- Suitable for water retaining structures.
- High resistance to the effect of long-term weathering.
- Durable in all climate conditions.
- Nontoxic – Ideal for potable water tanks.
- Flexible with thermal expansion similar to concrete.
- Excellent bond to concrete and masonry.
- Good crack accommodation capacity.
- Blocks passage of water – seals pores.
APPLICATION:
- Concrete structures like sunken portion, toilets, balcony, basement, chajjahs, terrace & small podium slab
- Pools and fountains
- Reservoirs and channels
