How to Seal Tile Grout

I get asked all of the time, do I really need to seal grout?

The answer is yes. 

Yes, you do.

Grout is generally made from a mix of water, sand, and cement (unless you are installing tile with small grout lines like mine which required unsanded grout.) Which means the finished product will dry with microscopic spaces in between the sand/cement and is porous. Water and liquids can seep through and cause mold and mildew on your subfloor and trust me when I say this, it is NOT a fun thing to remove and replace.



This is only one small part of the moldy bathroom subfloor I had to remove and replace. 0/10 do not recommend.


Not to mention, even when dry, if the grout is not sealed it is very easy to remove by getting it wet. That's great when you need to clean hazy tile after grouting it but not great for long term wear and tear. This is why you need to add a sealant to protect the grout from liquids and such.

Fortunately, sealing grout lines couldn't be easier. Here's how to do it.
