Tile grout Weber.18kg

• High resistance to the chemical used in cleaning agent and the chemical
• Resist to the water pressure in swimming pool
• Suitable for joint width between 2 to 10 mm without cracking. 

Q: Why is pool grout so much more expensive than ordinary grout? 

A: Chemicals added to pool water tend to degrade cement-based grouts. This is minimised if the water is maintained at the ideal levels but the choice of grout and its chemical resistance are important factors for the durability of the installation.

When the adhesive and grout in used are not specifically designed for swimming pool, the grout will be affected by chemicals added to the pool water. This allows water infiltration into adhesive layer and will cause tiles being dislodged.
