Dap 18387 Premium Elastomeric Sealant, Crystal Clear, 5 Oz.

DAP Premium Elastomeric Sealant is a crystal-clear, all-purpose synthetic rubber-based sealant designed to seal, patch, and waterproof a wide variety of indoor and outdoor surfaces. This flexible sealant creates an invisible, durable seal that stays clear, making it ideal for projects where appearance matters. Whether you're sealing roofs, gutters, RVs, windows, or other building materials, this sealant provides reliable protection against air, water, and moisture infiltration.

The unique elastomeric formula allows the cured sealant to remain flexible and crack-proof even in cold weather, preventing the seal from breaking as materials expand and contract. It adheres strongly to wet or damp surfaces without losing bonding ability, and it can be applied across a wide temperature range for all-weather use. The cured sealant is mold- and mildew-resistant, providing long-term protection.
