Using this DYNAFLEX 230® Premium Elastomeric Sealant is easy. First, make sure the surface is clean and dry. Apply the sealant evenly to the joints you want to seal, whether it's indoors or outdoors. Since it's ready to paint in 2 hours, you can add a fresh coat of paint soon after application. Remember, it can seal joints up to 2 feet wide, so it's suitable for a variety of projects. When it comes to clean - up, just use water. It has a low odor, so you won't have to deal with any strong smells. As for maintenance, there's not much to do. Thanks to its 100% waterproof and weatherproof seal, it should last a long time. And don't forget, it comes with a lifetime warranty. However, always check the joints occasionally to make sure the seal is still intact.
