Learn the tricks to sealing up leaks around your home with rubber sealant. It’s the fastest and least expensive way to protect your home from the elements.
What is rubber sealant?
Rubber sealants bond to common building materials around your home and keep out rain, moisture, cold air, and insects. These sealants are excellent adhesives and cling tightly to surrounding materials.
The flexibility of the rubber allows them to stand up to the expansion and contraction of adjacent materials without cracking or separating. This makes rubber adhesive sealant the perfect product to fill gaps and cracks in gutter systems, roofing materials, windows, and other areas.
How to use silicone rubber sealant to stop gutter leaks
Gutter leaks are annoying and can lead to stains down the wall or even water damage to your home. Repairing gutter leaks with rubber sealant isn’t difficult. Here are the basic steps:
- Locate the leaking joint. For example, look for signs of water stains or observe your gutters while it’s raining.
- Remove all debris, leaves, and dirt near the leaking area and allow the gutter to dry.
- Apply the waterproof rubber seal to the inside of the gutter, along any leaking seams, screw holes, or gutter connections.
- If necessary, use a smoothing tool, disposable paint brush, or gloved finger to smooth out the sealant and allow it to dry.
Always work safely. We recommend wearing work gloves or nitrile gloves when working with sealants. Wear eye protection if working overhead or with materials that may splash or spray into the eyes. Use caution when working on ladders. Place them only on stable, level ground. Never place the ladder on boards, bricks, or other objects. Make sure the angle of placement is within the manufacturer’s recommendations.
Using black rubber sealant to seal roof leaks
Roofing shingles, tiles, and even metal roofing can develop cracks or gaps, allowing water to leak in. Sealing these as soon as possible is important to prevent further damage.
The steps for using rubber roof sealant are simple:
- Clean away old sealant, dirt, grit, or anything else that may inhibit the bond.
- Make sure the area is dry before applying sealant.
- Using a caulk gun, fill the crack or gap with roof sealant. If necessary, smooth the sealant with a putty knife or disposable brush.
Don’t forget about your windows. Silicone rubber sealant is also highly effective at stopping drafts, moisture, and insects from entering through windows.
It’s a good idea to inspect the exterior of your windows periodically. Give special attention to where the window trim meets the siding, brick, or masonry. Seal up any gaps with a silicone rubber sealant.
While you’re doing this, you might as well check other possible problem areas for gaps. For example, inspect the ductwork, plumbing or drain pipes.
If you keep up with this essential maintenance, you'll be amazed at your home's energy savings and increased comfort level.
Choosing the right rubber adhesive sealant
Always choose a rubber sealant designed for the area of your home that you wish to repair. Read and follow the label and the manufacturer’s instructions.
Roofing sealants are extra durable and will stand up to the full brunt of the weather and keeping out water. Though most rubber roof sealants are black, there are also clear roof sealants that will not be as visible.
Gutter sealants should be extremely flexible and adhere tightly to the metal to prevent leakage. You’ll likely have a choice between a silicone rubber sealant or a synthetic rubber sealant for this type of repair.
If you just have a minor repair to make, don’t bother getting out the caulk gun or putty knife. Try Loctite Super Glue Power Gel Control. The unique gel formula is rubber-infused and remains flexible. Yet it forms an extremely strong and durable bond. It is weather and shock resistant and dries transparent. It bonds quickly to wood, metal, porcelain, and most plastics.
