Frequently Asked Questions
When should I use unsanded grout?
Use it for joints 1/8 inch and narrower, and on scratch-prone surfaces like polished marble and glass tile regardless of joint size. It packs tightly into fine joints where sanded grout would leave voids.
Can I use unsanded grout on floors?
Yes, as long as the joints are 1/8 inch or narrower — common with rectified tile. For wider floor joints, sanded grout resists cracking better.
Why does unsanded grout come in smaller bags?
Narrow joints use far less material, so unsanded grout ships in 9.75 lb bags versus 25 lb for sanded. One bag typically handles a standard backsplash or shower wall.
