How It Works

A standard 10.3 oz caulk tube fills about 90-100 linear feet of a 1/8-inch bead. Wider gaps need exponentially more caulk. Use paintable acrylic latex caulk for interior trim. Silicone caulk is for bathrooms and kitchens but is NOT paintable. Cut the tube tip at a 45-degree angle for a clean line. Smooth with a wet finger.
