Many contractors are finding they need to apply firestop products as part of a passive fire protection system in new construction projects or during major renovations. Lemmer has several pumps that work very well with products specified as sprayable, provided that appropriate accessories are used. A listing of those pumps and accessories is shown below.
When spraying fire stop materials, contractors should remove the high pressure filter element & core along with the gun filter and spring to prevent unnecessary plugging. For some of the thicker products, the ‘rock stopper’ intake filter should also be removed for best results.
It is very important for the user to follow all recommendations from the coating manufacturer regarding preparation, application and cleaning when using firestop products.
