Dap Inc 18860 Latex Sealant 5.5 Oz Clear Paintable

Product Description

The DAP INC 18860 is an advanced indoor and outdoor premium latex sealant formulated for permanent, flexible sealing against water infiltration, air leaks, and insect entry. Sold in a 5.5-ounce cartridge in a clear finish, this product is waterproof and paintable, making it suitable for finish-sensitive applications. It delivers outstanding adhesion and flexibility while remaining easy to tool. Cleanup requires only water, and the low-odor formula reduces disruption during occupied-space work. The cured seal resists mold and mildew, supporting long-term performance in moisture-prone areas.

This sealant is intended for residential and light commercial applications where a durable, flexible seal is required at building envelope transitions. Typical installation points include window and door frames, exterior siding joints, trim, molding, and baseboards. It performs in both interior and exterior environments, making it a single-product solution for multi-zone sealing tasks on the same job. Trade professionals use it during new construction, renovation, and weatherization work to reduce energy loss and seal pest entry points.

Installation Notes

Installation is typically performed by general contractors, weatherization technicians, or plumbing and HVAC trades during rough-in or finish stages when sealing penetrations and joints. Surfaces should be clean, dry, and free of dust, grease, or loose material before application. Apply sealant within the recommended temperature range indicated on the product packaging and tool the bead before skinning begins. Water cleanup should be performed promptly before the product cures.
