USES

Extensive water repelling of exposed porous roof tiles, concrete rooftop, cement plaster, brick, gypsum, limestone, terra-cotta, clay tile, outdoors stone monuments, historical buildings, temple statue, bridge girder, drain culvert etc.
Reducing sulphurous gases and acid that penetrate the building material by capillary action. Reducing salt formation & damages.

FEATURES

W4 is a water miscible solvent-based micro-emulsion concentrate based on silane / siloxane.
W4 works by penetration and micro-crystallisation, expanding and filling itself in the pores. At the same time, it allows breathing, so that trapped moisture can escape, reducing salt formation that causes con-crete spalling, efflorescence, cracking and fungus growth.
W4 will impart water droplet effect to the treated surface, reducing water absorption by up to 99%.
W4 has been giving long-term performance of up to 20 years (with slight yellowing on white marble sur-faces). It is not affected by UV and abrasion
W4 is a good concrete sealer before painting. It seals against alkaline breaching and improves paint ad-hesion. Extending paint service life by 2 to 3 years. It can also be added into emulsion paint at 1% level before painting. W4 is water miscible, and is environmentally friendly.

APPLICATION METHOD

W4 is a highly concentrated solution.
Dilution: W4 + Clean Water = 1 + 50 (use it within 24 hours)

Stone is sensitive, test apply on a small area, to check on the changes in shade. Before full application.

CAUTION

Avoid naked fame. Do not apply by mist spraying. Use in a well-ventilated area.
Do not use W4 to waterproof the bottom surface of the marble and stone tiles as it will lead to de-bonding.
Do not allow W4 to form a wet puddle as it produces a dark and oily silicone stain. Stain can be removed by burning it with a gas torch and scrubbing.
Highly polished light coloured tight grain granite and marble tiles have to be handled with care. Do not over coat to avoid wet looking silicone stain. Silicones Stain can only be removed by polishing.
