Have you just embarked on tile installation and now realized there is a myriad of choices beyond that in the form of grout? Not sure what the difference between Sanded and Non-Sanded grout is? In simple terms, Sanded grout with stronger. The strength of the sand makes it a better option for larger grout lines. While, Non Sanded grout has no sand, as the name suggests. It is idea for wall tile and tiles that use small grout lines like marble or rectified porcelain.
Here are some guidelines to help you decided which to use:
Most stone requires non-sanded grout to protect from scratches (exceptions include: Cobblestone and Slate).
Spacer sizes 1/16 – 1/8 require a NON-sanded grout. This spacer size is used for natural stone, polished stones, rectified porcelains and some wall tile. The non-sanded grout will not scratch your product during grouting application. This gives a smooth and elegant look.
Ceramic and porcelain floor tiles MUST have 1/8th inch grout line unless they are rectified.
Any spacer size larger than a 1/8th should have Sanded Grout.
Make sure to add Grout Admix when mixing your grout for a non permeable bonding seal that last the life time of your floor! Or Seal your Grout 3 days after application and continue to reseal once a year.
