Product Details

STI WF310 Intumescent Firestop Caulk, Red, 10.1oz Cartridge

WF300 Caulk is a latex-based, high solids firestop caulk. This material, when properly installed, effectively seals penetration openings in wood frame construction against the spread of fire, smoke and combustion byproducts.

WF300 Caulk is a single-stage intumescent. When exposed to elevated temperatures, WF300 expands rapidly to seal off voids left by the burning or melting of combustible materials.

WF300 Caulk is storage stable (when stored according to manufacturer’s recommendations) and will not separate or shrink when dried. WF300 adheres tenaciously to common construction materials such as lumber and gypsum board as well as typical penetrant materials.

Features:

  • Installer friendly, easily applies with standard caulking gun
  • Suitable for combustible and non-combustible penetrants
  • Tested for up to 3 Hours of fire exposure when tested to ASTM E814/UL1479
