Exterior Caulking Instructions

  • Exterior Caulking

    You should apply exterior caulking to seal against drafts. It also prevents moisture from entering your home and keeps heated or air-conditioned air inside. Properly caulking helps keep your house weather-tight, lowers heating and cooling bills, and prevents damage to structural elements. You should also caulk before painting with a paintable caulk, as it eliminates edges where the paint may start to peel and creates a better edge.

    Be sure that you exercise care on ladders and follow the precautions and warnings on your ladder.

  • Overview

    In caulking, you need to consider the type of caulk you will use, prepare the caulk gun, practice to get a smooth bead, and caulk all the gaps in your house exterior.

  • Choosing Caulk Type

    There are two factors to consider in choosing caulk. The first is how the caulk will be used. Don’t use interior-grade products for outside applications, as they will not last very long against the elements.

    The second factor is the warranty. The longer the warranty period of the caulk the better quality it is. Higher quality caulk will seal better and stay more flexible under various conditions. It is definitely worth the extra cost.

  • Installing the Caulk Tube

    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. Then, take your thumb off the release.

    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 long nail to puncture the inner seal of the cartridge.

  • Applying a Caulk Bead

    To make your caulk the smoothest, remove all old caulk and make sure the surface where you apply the new caulk is clean and dry. Place the nozzle at a 45° angle to the seam being sealed. Gently squeeze the handle of the caulk gun and draw the gun backwards, toward yourself. Do not move the gun away from you, or your caulking will be sloppy. Practice matching the pressure on the handle and the speed at which you move the gun to get a smooth, even flow. Wipe up any drips with a rag or paper towel.

  • Sealing Large Gaps

     

    There is no need to flatten or shape the bead of caulk to get it to look concave, or depressed. As the caulk cures, it will shrink to form a concave seal.

    To seal an especially large or deep gap, you will need to place filler material in the opening. Wood, fabric, insulation, or even rope will work well until the opening can be sealed at the surface. Then apply caulk to seal the hole and cover the material.

  • Caulking All Areas

    In order to effectively caulk, be sure that you get to all the areas that should be caulked. 1) where siding meets doors and windows, 2) along the house trim, 3) at corners of the house, 4) around outside faucets and dryer vents, and 5) where the siding meets the foundation. Once you have caulked all these areas, your house will be sealed tight, and you will be able to prepare for any exterior painting project you have.
