{"title":"Log Home Caulk \u0026 Sealant","description":"\u003ch2\u003eLog Home Caulk \u0026amp; Sealant\u003c\/h2\u003e\n\u003cp\u003eLogs are in constant motion — expanding, contracting, settling, and checking as the seasons and moisture levels change. That movement opens gaps, cracks, and checks that let in water, air, and insects. The right log home caulk and sealant flexes with your logs to keep that seal tight for years. At Wasatch Timber, we carry the Sashco sealant line built specifically for log structures, including Log Builder, Conceal Textured Caulk, Big Stretch, and the backer rod you need behind every joint.\u003c\/p\u003e\n\n\u003ch3\u003eWhich Sealant Is Right for Your Job?\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eLog Builder\u003c\/strong\u003e is the sealant made for log structures. It stretches up to 500% of its original size while keeping a tenacious bond to the wood, making it ideal for checks, cracks, and joints in log walls. \u003cstrong\u003eConceal Textured Caulk\u003c\/strong\u003e is formulated to disappear into the woodwork — its textured finish blends seamlessly so you can't tell where the wood ends and the caulk begins, perfect for a natural look. \u003cstrong\u003eBig Stretch\u003c\/strong\u003e is a high-performance elastomeric sealant for general gaps around the home: trim, baseboard, crown moulding, and siding.\u003c\/p\u003e\n\u003cp\u003eBehind every joint, \u003cstrong\u003ebacker rod\u003c\/strong\u003e does the quiet but critical work: it controls how deep the sealant sits, prevents three-sided adhesion, and lets the caulk stretch properly as logs move. Skipping backer rod is the most common reason sealant fails early.\u003c\/p\u003e\n\n\u003ch3\u003eWhen to Caulk Your Log Home\u003c\/h3\u003e\n\u003cp\u003eBecause most logs move significantly in the first few years after construction due to moisture loss and shrinkage, it's important to caulk early with a product designed to move with them. On a first finish, the general best practice is to stain first and caulk last — the stain acts as a primer that helps the sealant adhere and adds a protective barrier behind the joint.\u003c\/p\u003e\n\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eWhat's the difference between caulk and chinking?\u003c\/strong\u003e\u003cbr\u003eCaulk and sealant are for narrower gaps, checks, and cracks — typically under 1 inch. Chinking is for the wide joints between logs and creates the signature textured mortar look. Many log homes use both.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHow much sealant do I need?\u003c\/strong\u003e\u003cbr\u003eMeasure the total linear feet of gaps and the average gap width and depth. Tube and bulk coverage varies with joint size, so estimate generously and keep extra on hand.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCan I caulk over old caulk?\u003c\/strong\u003e\u003cbr\u003eOnly if the existing sealant is clean, sound, and well-bonded. Remove any cracked, peeling, or failing material first.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDo I really need backer rod?\u003c\/strong\u003e\u003cbr\u003eYes, for most joints. It sets the proper depth and prevents the sealant from bonding to the back of the joint, which is what allows it to stretch as your logs move.\u003c\/p\u003e\n\n\u003cp\u003e\u003cem\u003eNot sure which sealant fits your project? \u003ca href=\"\/pages\/contact\"\u003eGet a free quote\u003c\/a\u003e and we'll help you spec it.\u003c\/em\u003e\u003c\/p\u003e","products":[{"product_id":"conceal-textured-caulk-for-wood","title":"Conceal Textured Caulk for Wood","description":"\u003cdiv class=\"wp-block-group is-layout-constrained\"\u003e\n\u003cdiv class=\"wp-block-group__inner-container\"\u003e\n\u003ch4 class=\"wp-block-heading\"\u003eEasy to Use – Hard to See.\u003c\/h4\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cp\u003eKeep out weather, bugs, and moisture without seeing it.
