Choosing Your Caulk Gun


Play Video

We are presenting a simplified table which shows the various levels of viscosity each gun can handle.  Viscosity is the resistance of a fluid to flow; its “thickness” (i.e. low viscosity material means it is thinner). These are just general rules of thumb; when it comes to specifics about materials, we suggest you contact the material manufacturer for the best results. Each category presents a link to the section where you can find the individual model with a thumbnail and description.
