When It’s Time To Grout

There are many different types of grout and it’s important that the right one is used for the type of tile that’s being installed, whether it’s for a backsplash, kitchen floor, bathroom, shower or fireplace. An expert opinion never hurts.
Some grouts have sealants in them, some don’t; some are sanded, some aren’t; and they come in different colours, too. (Try to stay away from whites and lighter colours because they will get dirtier, faster!)
Then there’s ready-mix grout that comes in a pale or the powder kind that requires water. Every grout has its own set of rules and instructions, and they must be followed to a tee. But a general rule of thumb is that grout should be the consistency of peanut butter.
To Seal Or Not To Seal
Grout is porous, so it will absorb vapour and moisture. In order to prevent this moisture from being trapped behind the grout and tiles, which can lead to mould and rot, grout needs to breathe. For this reason, Mike always recommends not sealing grout.
If the grout comes with a sealant or the homeowner insists on the grout being sealed to prevent stains or it looking dirty, it is crucial to make sure the sealant is breathable.
But what’s Mike’s bottom line? DO NOT SEAL GROUT!
