Building an average 2000-sq.-ft. home requires about 24 large tubes of subfloor adhesive, but you can do the same job with only three 29-oz. cans of Tytan aerosol subfloor adhesive. The “collapsing gel formula” expands less than other brands of aerosol polyurethane adhesive, so the subfloor stays tight to the framing. Once you’ve applied it, you have about 15 minutes of working time before you have to lay down and fasten the subfloor, which compares favorably to conventional solvent-based construction adhesives. As the product cures, it expands to fill any gaps that could cause squeaks later. You can use Tytan on wet and frozen lumber and in temperatures down to 23°F. The 29-oz. gun-dispensed can costs $18. Straw-dispensed cans sell for $7 (12 oz.) and $10 (20 oz.). Tytan foam guns start at $16 for an economy model and reach $77 for a top-of-the-line version with a 39-in. barrel. Five other guns are priced in between.
