How Often Should You Re-seal Grout?
Cement grout should always be sealed upon installation. It should also be re-sealed on a regular basis. Most recommendations suggest re-sealing grout lines once a year. Depending on where the grout is, it might be necessary to do it more often. Moist areas or areas where the grout lines are subjected to harsh weather conditions might require more frequent maintenance. Grout lines outside, in the shower, or around sinks are likely to suffer more damage from moisture, so more frequent re-sealing is required. If you are ever in doubt about the state of the sealant on your grout, you can test the seal by placing a few drops of water on the grout lines. If the water gets absorbed, the grout lines need to be sealed again.
Typically, epoxy grout doesn't require sealing. Epoxy grout is far superior to cement-based grout and less prone to the effects of weather, heavy traffic, and other damage from outside sources. That being said, you don't need to seal epoxy grout. Other types of grout, though, has to be sealed, as a measure of protection and to help enhance the grout by adding a layer of sealer that can extend the time between maintenance sessions.
How to Seal Grout
It's important to know how to seal grout properly. There's more to sealing grout lines than simply applying the sealant. Knowing how to seal grout properly will ensure you extend the life of your grout dramatically.
First, ensure you have the right kind of sealant at your disposal. There are sealants specifically for epoxy grout, sealants designed for cement grout, and versatile products that work well for both applications. The important thing is to use a high-quality grout product you can rely on to provide maximum protection.
Make sure your tile and grout lines are clean. If not, you will seal the dirt into the grout lines. Use a damp cloth to remove any dirt, grime, or excess grout from the tiles. Next, apply the grout sealant. Use small amounts of the sealant at a time. You can apply the grout sealer with a paintbrush, paint pad, paint roller, or clean towel. Evenly distribute the sealant over the grout lines and saturate the surfaces. When you've completed the first coat of grout sealer, let it dry for 10 to 15 minutes. This allows it to penetrate the grout for maximum protection. Apply a second coat of grout sealer following the same steps. Let the grout sealer cure. In most cases, 2 to 3 hours is sufficient. To ensure the sealant is working, you can test it by applying a few drops of water on the grout line. The water should form a puddle on the grout. If the water is absorbed, you will need to reapply the sealer. It's a good idea to apply this test at various locations on the grout lines to ensure you've applied the grout consistently throughout.
