- Excellent adhesion to most building substrates.
- Improves flexural, tensile, and thin section fragility of cementitious systems.
- Allows breathing, thus preventing peeling and scaling.
- Gives a tough, hardwearing surface with effective waterproofing.
- Reduces chloride salt penetration in marine environment.
- Self-curing & non-toxic and thus can be used for coating structures storing potable water.
- Is non-toxic and thus can be used for coating structures storing potable water.
- For concrete repairs - Spalled concrete of floors, columns, beams, chhajja, slabs, parapets, etc.
- For waterproofing – Small roof terraces, sunken portions of toilets & bathrooms, chhajja & lift pits, balconies.
- As a bond coat – For bonding of new concrete to old concrete, masonry stone work, plastering.
- For cladding – Fixing or re-fixing of slip bricks, tiles, stones & marble bedding.
- As external rendering – Weatherproof & frost resistant render.
- As bonding slurry coat for pinhole treatment on concrete surface.
