What is the purpose of grout sealer?

Since grout is typically made of porous cement and sand, grout sealer is used to prevent it from soaking in damaging elements such as stains, moisture, and microbes. The sealer, which is waterproof, works by coating the surface to keep off the aforementioned element from coming into contact with your sanded and unsanded grout.

In doing so, grout sealer helps to maintain the sparkling appearance of your flooring. The last thing you want is an unsightly floor with unevenly-colored grout lines due to the absorption of water and food stains. What’s more, microbes/ fungal organisms like mold spores tend to make habitats out of unsealed grout. As you may be aware, the smell of mold within your house is usually unpleasant, and mold also presents a human health hazard. You can prevent mold growth on your grout by sealing it with a grout sealer. But, can I seal tiles before grouting?

Does all grout need to be sealed?

No! Not all types of grout have to be sealed. Epoxy grout- for instance- is non-porous, hence negating the need for a sealant. The fact that it’s also flexile minimizes epoxy grout’s susceptibility to chips and cracks.

How often should you seal grout?

Ensure to re-seal your grout at least once a year, as the old sealant is likely to wear down in various parts within that time period, depending on foot traffic within the house. However- for rooms that aren’t used that frequently like the bathroom- you can re-seal the grout lines every couple years; as the sealant takes longer to wear out in such areas.

If in doubt whether your grout needs a new sealer coating, you can always use the water-test; whereby you spray water onto the surface of the grout and take mote of what happens next. If the water beads up on the surface of the grout lines, then your sealant is still intact.

If it however soaks in/ drains into the grout, it means your old sealer has been worn down and it’s time to re-seal. Alternatively, you can always contract the services of a professional at It’s All Clean San Diego to determine whether resealing is necessary, depending on the type of grout you have installed and its quality.
