Whether your tile is installed on the floor, walls or countertop, sealing the grout is the last step in the project. Grout is a mortar-like substance used to fill in areas between tiles, help secure them and create a finished look. Standard cement-based grouts are porous and can stain easily when left unsealed. Grout sealer also makes regular cleaning of grout joints easier and can make them more water-resistant. It is imperative that you again allow grout to dry completely before applying a sealer.
Things to remember about grout sealing
Grout should remain slightly damp as it hardens to prevent dark spots. You will need to monitor your grout to ensure that it cures properly and all in one colour. If the sun comes through a window and shines on a particular part of your grout for hours each day, block the window with a thick curtain. Grout near a heating or air register can dry too quickly, so mist with a little water each day to keep drying at the same rate as the rest of the grout. The grout will still cure properly even if you keep it a little damp.
How long to wait for group sealing
Follow the grout manufacturer’s directions for curing time. Some need grout only three days before closing, while others may need two weeks. Seven days is an often-recommended waiting period. Curing time is affected by humidity, temperature and other environmental factors; adjust your wait time based on current conditions. Ideally, you should avoid using and prevent traffic on cemented areas before they are sealed, to minimize the risk of staining or soiling the grout.
Why should you wait
Several things can go wrong if you seal the grout too early. Premature sealing traps moisture in the grout, delaying curing and creating colour variations. Grout that contains trapped moisture is not as strong as grout and the tiles as properly cured can start to loosen or fall off. This is why patience is imperative when waiting for the grout to heal.
Not all groups are meant to be sealed, and not all hunters are suitable for all types of grout and tile. Choose your sealant carefully depending on the type of grout and tile in the installation. Sealers on natural stone tile installations can be designed for application to both tile and grout. Epoxy grout does not require a sealer. And some modified latex grouts can resist the absorption of certain types of sealants. If in doubt, consult the grout (and tile) manufacturer or an expert tile supplier.
How Long Does Ceramic Grout Floor Take To Dry?
When you install cement over ceramic flooring, you must make sure that you allow plenty of time to dry before walking on it. In most cases, you should allow the grout to dry overnight before walking on the tile. It can take up to 24 hours in some cases. If you are thinking about sealing the grout after you have installed it, you have to wait even longer than that so that all the moisture has had time to be released. In most cases, this process will take as long as 72 hours to complete. To make sure you allow the grout ample time to dry, check the directions on the package.
