This video will show you how to seal your tile grout to help prevent mildew, mold and stains. You can seal tiles in your bathrooms, kitchens, and tile floors. In this video I’m using Aqua Mix Sealer’s Choice Gold Professional sealer, but there are also many other brands of sealers on the market. You should apply grout sealer in a well-ventilated area, while wearing protective gloves and eye gear.
