Our take on the DAP Polyurethane Construction Adhesive Sealant 18810

DAP Polyurethane Construction Adhesive is a single-component, moisture-curing polyurethane sealant in a 10.1 fl-oz cartridge. It bonds to most building materials, spans gaps up to 1/2 in. by 1/2 in., and stays flexible across a wide temperature range. It suits exterior and interior structural sealing where a paintable, long-lasting joint matters. Against silicone and acrylic caulks, it offers stronger grab and wider gap filling, but it cures slower and skins over in hours, so plan around the wait.

Questions and answers

How long before I can paint over it?
Let it cure fully, typically 24 to 48 hours. It dries to the touch in 3 to 6 hours, but paint adheres best after full cure.
Can it be used on wet or damp surfaces?
It cures with moisture and handles damp conditions, but surfaces should be clean and free of standing water for a reliable bond.
Does it work on concrete and masonry?
Yes. It bonds to concrete, brick and masonry, and its flexibility handles the small movement those joints see.
Will it hold up outdoors in freezing winters?
Yes. The cured sealant is rated for service from -40 F to 185 F, so it handles freeze-thaw cycles.
Can I use it below 40 F?
No. Apply it only when surfaces and air are between 40 F and 110 F.
Is it sandable or overpaintable?
It is paintable after cure. It is a flexible sealant, not a wood filler, so it is not meant for sanding.
Where is the DAP Polyurethane Construction Adhesive Sealant 18810 cheapest?
At Amazon, for $8.59, as of our latest check.
