Spray glue for EPS to brick?

guillow | Posted in Green Products and Materials on

Hi, trying to glue some EPS panel to brick. Was wondering what kind of glue would be efficient to do that over 800 sq ft?

Could you use a spray insulation product like Sika Boom AS-PRO?

    I would use a foam board adhesive like the one in Loctite's PL line (PL300). A lot adhesives will react with (chemically "melt") foam board, so you have to be careful what you use. You also need something fairly thick since you're trying to glue to a less than ideal surface here. Spray adhesives tend to be very thin, so they don't work well on very rough and irregular surfaces.

    You might need to press the foam to the wall with some type of temporary brace while it is setting up. Or you could use a fastener such as

    Thanks. It seems like the building science company created a nice document for the DOE, and they had recommended using a spray gun foam adhesive versus normal building adhesive. But I can't seem to find that easily.

    Is there significant difference in the building adhesives to the great stuff pro wall and floor spray adhesive?

    Def will be looking for using some kind of brace to get it set. Hopefully can find a good way to use some 2x4 and stubs to make a brace...
