What You Need

• Putty knife

With Flex Paste, there is no need to shake or stir, it’s already ready to go! Grab a putty knife, trowel or similar tool, and remove an even layer of material from the top of the tub. Don’t scoop too deep! Scooping too deep can cause air pockets that dry out the Flex Paste.
