Should I Paint Over Dark Grout Lines?

What Is Grout?

Using an adhesive / mortar mix when laying tiles on walls or floors is necessary. Once it has dried and become secure, the space in between the tiles must be filled. This is where you use grout. It’s a dense fluid used to bond and seal the joints between tiles, creating a seamless appearance.

An added benefit is that grout makes everything look appealing after it’s applied. When applied, a compressible joint is created to alleviate minor stresses within the installation (not to be confused with movement joints, which are still required) and provides a neat transition between adjacent tiles to accommodate manufacturing tolerances within tiles.

Why Do You Need It?

Grout is a necessary and integral part of many tile jobs. It keeps moisture out of the substrate, helps keep tile lines straight and prevents tiles from rubbing against one another and cracking.

Grout is porous and lower than the surface of your tile floors or counters. This makes it highly susceptible to staining and discoloration. Many home and business owners believe painting the grout lines is the best solution to restore the appearance of their tile surfaces.

There are many products such as grout pens, epoxy paint, traditional paint, and other grout colorants that are advertised as a quick fix for your unsightly stains, but are any of these actually a good idea for your home?

The honest answer is no. Applying the grout paint over dark and dirty grout lines is just placing a thin layer over germs and bacteria. Our team are tile and grout cleaning experts.
