NexusPro is a silicone-based sealant for joints and cracks specially formulated to provide long-lasting flexibility and to stand up to harsh weather conditions. Unlike traditional polyurethane sealants, NexusPro resists UV rays, which means it won't crack, bubble, or dry out. That means a single application can seal the joints and cracks in your concrete driveway, patio, pool deck, or sidewalk for years to come, protecting it from damage caused by soil erosion and washout.
