You can have a look at the grouts available in the photo attached. These grouts materials are many more times better than cement grouts which are normally used in Singapore. These new grouts materials are completely anti-stain, anti-mold, waterproof, no cracking and no discoloring. Even if you had already put the grout, it can be removed and then replaced by these new grout materials. The grouting craftsmanship is guaranteed!
