How to Use a Caulking Gun?
1.There are two factors to consider in choosing caulk. The first is chemistry. Generally, any brand of exterior silicone caulk will give excellent results. Don’t use interior-grade products for outside applications. The second factor is the warranty. The longer the warranty period of the caulk the better quality it is. Caulk with a 40-50 year warranty is better than that with a 25-30 year warranty; and 25-30 years is better than 15-20. Higher quality caulk will seal better and stay more flexible,and is worth the extra cost. 2.To load the caulk gun, use your thumb to press the release on the rear of the gun, and pull the plunger all the way back. Slip the cartridge into the gun and push the plunger in snugly. Take your thumb off the release. 3.Cut the end of the nozzle on the cartridge so the opening matches the size of the gap or seam you’re sealing. Then use a screwdriver or length of stiff wire to puncture any inner seal in the cartridge. 4.Place the nozzle at a 45° angle to the seam
