FAQ

What are the benefits of sealing grout joints? How do I seal grout joints?

Generally, most grout joints are filled with materials made from cement, making the filling material porous and absorbs liquid readily. Consequently, grime, water and moisture can seep through it and under the tile. After a prolong period, problems such as debonding of tiles and hollowness may occur.

Sealing grout joints will reduce/prevent the growths of mold and mildew. It also prolongs the tile lifespan and minimize damage to a considerable extent by keeping water and moisture out.

Before sealing grout joints, carry-out a simple test by releasing droplets of water onto the grout. If it absorbs water, it is a tell-tale sign that the grout joint needs sealing.

Normally, grout joint sealing materials comes in liquid form. To seal grout joints, apply 2–3 layers of the sealing material onto the tile grout.
