Your log home has a stunning exterior that is at once both striking and inviting. Yet the natural wood that makes your log home so beautiful also makes it vulnerable. Rain, snow, hail and wind can all break down and dull the surface of the wood over time, causing the exterior to become cracked, discolored, faded or even rotted. Perma-Chink Lifeline Exterior Semi-Transparent Wood Finish has offered proven protection for wooden exteriors for over 20 years. Just a thin coat of this sealant is all you need to protect your home from the elements. The solution is breathable and flexible to allow the wood to expand and contract throughout the year with seasonal changes. At the same time, it allows the wood to stay dry to prevent mold and rotting. Protect the beauty of your home while also saving on the cost of maintenance and repair over the years. 

Proven for over 20 years on thousands of log and wood homes across the globe, original Lifeline Exterior has stood the test of time. Lifeline Exterior forms a thin film at the surface of logs where the protection is needed. 

Its breathability and flexibility allows logs to go through seasonal expansion and contraction while drying out to their core. Apply a clear topcoat of Lifeline Advance to maximize durability and minimize maintenance cost and labor.
