Painting Grout How-To

painting grout before applying floor decalsTwo weeks ago I showed you how I updated my tiled bathroom floors with these amazing floor stickers. The existing brown grout in the space was not going to go well with this gray and white pattern. I did some research on painting grout and decided that was the way to go.

Painting grout isn’t difficult, you just need to have a little patience. Luckily, this is a small room so it didn’t take me long to do. I debated between using white or gray grout paint, but decided to go with gray because it’s easier to keep clean and would also cover the existing brown grout better.

I started with the tapered one, but found it was too messy so I switched to the flat bristled brush. To buy just one of these little brushes can be expensive, I bought an inexpensive set of artists brushes awhile back that always come in handy for projects. You can find a similar set of artist brushes here.

My existing tile is textured so it wasn’t possible to get a perfectly straight line, though from a standing position it does look perfectly straight.

That’s really all there is to it! I spent about an hour and a half on painting grout this day,  to do a larger room would obviously take much longer. Here is what it looks like completed with the floor stickers. I’m really happy with the results! You can see the whole before and after floor project here.
