In one sentence, describe what the following article is about: Silicate sealers soak into the concrete and create a hard barrier that is waterproof. They can be painted over once they have dried. You can find these sealants at big box home care stores. Silicate-based sealers do not work on walls or areas that have already been treated or painted over. If you are planning on sealing new concrete, wait until it has cured fully, which usually takes around 4 weeks. Silicate and siliconate sealers can be applied as soon as the concrete can support your weight. Check the label on the product to determine the temperature range when it should be applied. If the temperature is hotter than listed, the sealer may crack or bubble, making it less effective. If applying the sealer outdoors, check the weather to make sure rain is not expected for the next 24 hours. If you're covering a large area, a sprayer is suggested. Otherwise, use a paint roller with in to in (6.35 mm to 9.5 mm) nap. Allow the first layer of sealer to dry for 2 to 4 hours before applying the second coat. The second coat should be applied in an opposite direction, or perpendicular, to how you put on the first coat. Avoid using too much sealer on one coat or else you will have puddles and bubbling. Try your best to avoid foot or vehicle traffic over your freshly sealed concrete. Areas with heavy traffic should be given the most time, about 3 days, to set before they are walked on again.
Summary: Purchase a silicate-based concrete sealer. Wait until the concrete has cured for 30 days. Apply when temperatures are between 50F (10C) or 90F (32C). Use a paint roller or pump sprayer. Apply 2 thin coats of the sealer to the concrete. Allow the sealant to dry for up to 3 days.
