Description
USES
- Waterproofing of toilets, wet areas, roofs and cement substrates.
- To stop rising dampness.
- Hardening of concrete floor surface to improve wear resistance.
- To increase acid resistance of concrete.
- To reduce dusting due to the micro-pitting causes by the soft Calcium hydroxide.
FEATURES
- W7 reacts with free calcium and water to form a non-water soluble Calcium Hydrate gel complex in pores, capillary tracts and cracks. This gel creates a sub-surface barrier against ingress of water and contaminants.
- W7 seals crack and porosity up to 1 mm permanently and reseals future hairline cracking.
- W7 reduces water transmission, stabilizes the Calcium particles and reduces efflorescence.
- Reduction of chloride diffusion coefficient by 89%.
- W7 is resistant to extreme weathering elements.
- W7 allows 50 % moisture vapor permeability and is able to take positive hydrostatic pressure.
- W7 hardens the surface thus improving wear resistant.
- W7 increases acid resistance for concrete.
- W7 reduces dusting due to the micro-pitting . W7 is non-toxic.
