Spray More Foam With Less Mess
New, improved dispensers and formulas are making the job easier—and cleaner
Polyurethane spray foam has long been our favorite way to seal up gaps and cracks around the house to keep out drafts. Here’s a guide to the latest products to hit home-center shelves.
1. Single-Use Can
Still the most common choice among homeowners for sealing around pipe penetrations and cracks, this product’s new straw solves the problem of extra insulation oozing out of the tip.
Great Stuff Big Gap Filler, 12-oz. can, about $5
The new straw clicks closed to stop foam overflow.
2. Pro-Style Dispenser
Look for new foam blends, like this one made to seal out pests (it has a bitter taste), and guns that offer more precision; they won’t clog when idle.
Great Stuff Pro Pestblock 20-oz. can, about $21, and Pro 14 Dispensing Gun, $55
The gun’s narrow tip sprays foam into tight spots.
3. 2-Part Tank
For medium-size jobs, like insulating a wall or ceiling, try this DIY kit—the foam and propellant mix in the nozzle. Yields enough to cover about seven standard stud bays.
Touch ’n Foam Pro System 200, $333
