Stop Wasting Foam
You can't beat spray foam for sealing around windows and doors or sealing large gaps and cracks in old house walls, foundations and attics, but how often have you run a can empty when you were so close to being finished? And how disappointing is it to use
a partial can, knowing you'll have to throw the rest away? If you're a regular spray foam user, it might be time to step up to a foam dispensing gun.
A dispensing gun allows you to save foam if the job requires less than a full can. Once the job is finished, just set the gun aside until the next time you need it. Leave the can on the gun if you know it will be used in less than 30 days, or pull the can off, cap it and then clean out the gun with cleaning solution. Besides saving you money on foam, the dispensing gun provides much greater control because you're not working with a flimsy straw, and the trigger can be adjusted with a turning setscrew to control the rate of flow—nice!
