- Air sealing
- Filling gaps
- Exterior sealing
A high-density polyurethane foam for air-sealing and filling gaps up to 1 inch, indoors or out. It dries a bright, paintable white that blends with trim, goes tack-free in about 8 minutes, and its UV-resistant density beats budget foams outside. Keep in mind it is rated only to 1-inch gaps, and the white yellows somewhat if left unpainted in sun.
Pros
- Dries a bright white that blends with trim and is easy to paint over, unlike orange/yellow foams
- Fast tack-free time of about 8 minutes speeds up multi-spot sealing jobs
- High-density, UV-resistant foam holds up better than budget foams on exterior use
Cons
- Rated only to 1 in gaps, so it is not a substitute for a big-gap or 3 in foam
- White color still yellows somewhat with long UV exposure if left unpainted
- Like all straw-applied cans, the tube clogs and the remainder is usually one-and-done

Frequently Asked Questions
- Why does the foam color matter?
- Because it shows. This one dries bright white, which blends with trim and paints over cleanly, unlike the orange and yellow foams that telegraph through a finish coat. It still yellows somewhat under long UV exposure if left unpainted.
- How big a gap can Tite Foam fill?
- Up to 1 inch. It is not a substitute for a big-gap or 3-inch foam, so measure the opening before buying — overreaching on gap size is where foam jobs sag and fail.
- How fast can you work with it?
- Tack-free in about 8 minutes and trimmable in roughly 50-70 minutes, which speeds up a multi-spot sealing session. Plan to use the whole can: like all straw-applied cans the tube clogs and the remainder is effectively one-and-done.
