Quick Answer
To seal an ice house against wind and water, use a combination of weatherstripping and sealants such as caulk and spray foam to fill gaps and crevices, and apply a layer of waterproof coating to the exterior surface. This will create a tight seal that prevents air and moisture from entering the structure. Regular maintenance is also crucial.
Weatherproofing Gaps and Crevices
Weatherstripping is a crucial component in sealing an ice house against wind and water. For traditional ice houses, apply weatherstripping around doors and windows to prevent air leaks. Use metal or foam weatherstripping, which can withstand extreme temperatures and last for several years. For example, use 1-inch wide foam weatherstripping with a thickness of 1/8 inch to fill gaps between the door and the frame. Apply it using a staple gun.
Sealing with Caulk and Spray Foam
To seal gaps and crevices beyond the reach of weatherstripping, use a high-quality caulk or spray foam. For caulk, choose a type that is specifically designed for use in cold temperatures and has a high level of flexibility to accommodate expansion and contraction. Apply it using a caulking gun, making sure to fill gaps completely and smooth out the surface. For spray foam, use a 2-part spray foam with a 1:1 ratio for best results. Spray it into gaps and crevices, allowing it to expand and harden before trimming excess.
Waterproof Coatings
To protect the exterior surface of the ice house from water damage, apply a waterproof coating. Choose a coating that is specifically designed for use on wood and can withstand extreme temperatures. For example, use a 100% acrylic latex coating with a 300 PSI rating to ensure it can withstand snow and ice loads. Apply the coating according to the manufacturer’s instructions, using a roller or brush to ensure even coverage.
