Moisture saturation in your basement is serious. Every homeowner should use waterproof paint to protect against this. Before applying waterproof paint, remember that the surface should be dry. To assure complete dryness, set up a dehumidifier, and use a wet and dry vacuum. Before applying any paint, make sure your basement walls are in good condition. Painting over damaged areas with waterproof paint is a waste of time. Make sure to fill any holes with fresh mortar, then allow time to cure before applying any paint. Also, make sure to thoroughly apply the paint, as many homeowners skip the spaces where the home settles, causing small gaps. Concrete is a porous surface that absorbs moisture and paint like a sponge. One coat of waterproofing paint won’t be enough protection, so apply several coats, allowing each to dry before applying another.
