CRES®PROTECT REP 200
Solvent based masonry water repellent
Ready to use surface water sealer based on a mixture of silane/siloxane polymer, Dilute solution of CRESPROTECT REP 200 in organic solvents serve as high quality general purpose water repellents for impregnating and priming mineral and highly alkaline substrates. It reacts with atmospheric moisture or pore water in the substrate, thereby generating the active ingredient while liberating alcohol. The active ingredient greatly lowers the water absorbency of the substrate, which nevertheless retains a very high degree of water vapour permeability since neither pores nor capillaries are clogged.
Properties:
- Good depth of penetration
- Tack free drying
- High resistance to alkalis
- Rapid development of water repellency
- Reduces efflorescence
- Protects surface from discoloration and weathering
- Breathable, allows interior moisture to escape without damaging the sealer
Uses:
It is suitable for imparting water repellency to absorbent, porous, mineral construction minerals like brickwork, all kinds of concrete, aerated concrete, sand-lime brickwork, cement fibreboards, mineral plasters, mineral based natural and artificial stone & mineral paints.
