Loctite Tite Foam Big Gaps Spray Foam Sealant, 12 fl oz Can, 1 Pack - Polyurethane Expanding Insulation

The best foam sealer.Was referred to this product for a repair behind old plaster, needed to fill a void and was told this was the best product for my task.It is remarkably sticky and you must wear gloves. But found that misting it with a bit of water allowed me to push back the foam that overflowed and smooth the surface. I was able to chip away the access foam once it dried and plaster over for a perfect finish. Highly recommended.

Cling Wrap, AND Gorilla tape WORK! When you don't want anything to stick when shaping.I used the gorilla tape to contour the shape of the hull where a fish finder would normally go; too much wear & tear was being created on the edges from rocks & sand.Used Cling Wrap to keep the Foam expansion to a minimum Why did you pick this product vs others?:Research, it's closed cell foamUse:After sanding to create a rough surface, used acetone to clean, then SHAKE 60 sec & spray😉

Worked perfectly thank you so much

It is as described.

This stuff is denser and better than the great stuff. This foam actually lifted a 4" thick (4X4 ft) slab higher than the set slope and maintained it. I used over 20 cans to lift over 100ft of sidewalk concrete slabs!

I bought two cans, one worked great the other must’ve been old because only a little came out then nothing. The can that worked worked great!

awesome
