Log home caulking can be used on the exterior of your logs or between them as they are being stacked. Log caulking materials are designed to expand and contract as your logs take on and give off moisture. Log home caulking can be applied on the interior, exterior or both sides of your home. Typically, it is applied in widths that range from 1/4'' up to 3/4''. The installation of backer rod is important prior to the application of caulking as this allows the material greater flexibility. Mountain Home Building Products is proud to handle such products as UV Guard Textured Caulk, UV Guard Premium Caulk, TimberMatch & TimberSet. Please call us to discuss your log home caulking needs.
