We Highly Recommed the Fix-A-Floor Professional Caulk Gun 10:1 Thrust Ratio Non-Dripless for application of our Fix-A-Floor Adhesives. It’s very important to squeeze gently on the trigger allowing for minimum of an 8-10 second stoke each time. If you move too fast or press down too hard with the gun, adhesive can escape out the back of the tube; so nice and slow. No Rush!
