DEWALT Expansion Foams TRIGGERFOAM PRO WIND&DOOR 29oz

TriggerFoam Pro is a one part polyurethane expanding foam which sets into its final form by using moisture present in the air. When installing the foam， consideration should be given to the additional expansion of the foam after it leaves the nozzle. The surface of the foam initially dries within 1-5 hours and becomes fully cured in 12-15 hours. Low pressure formula will not distort windows and door frames. TriggerFoam Pro sets well on ordinary surfaces such as concrete， brick， metal， etc. Surfaces do not require preparation and can also be damp. After installation， it is recommended that a full 24 hours elapse prior to scraping， sanding， staining or painting. The foam has a R-5 equivalent value when used in place of traditional installation methods.
