PROTECT TILING AREAS AND GROUTED JOINTS FROM EFFLORESCENCE

Problems of white stain, salt stain, limewater stain, and rusty stain on tiles and grouted joints are normally found on external areas where being covered with granite, marble, or natural stone. Places where these stains are likely to occur are like fountain, big sign of the buildings or hotels, and the places where there is the overflow of water.

CAUSES OF EFFLORESCENCE

1. Water-soluable salt from hydration reaction of cement and water migrating through porous surfaces reacts with CO2 in the air and then form the deposit of CaCO3 on tiling and/or grouting surfaces.

2. The migration of underground water through porous structures and then through covering materials.

FACTORS OF EFFLORESCENT EFFECTS

FACTORS OF EFFLORESCENT EFFECTS ARE FROM THE USE OF

1. Ordinary Portland Cement

2. Porous substrates/surfaces

3. Ambient temperature and humidity

4. Salt-bearing water

5. Underground water or water from the source being near agriculture areas

Solution

SOLUTIONS FOR TILING AREAS AND GROUTED JOINTS FROM EFFLORESCENCE

When there are upward and/or downward movements of water through structures, and then through the layer of tile adhesive
