Lifeline Ultra-7 is the most durable exterior stain that Perma-Chink Systems has ever developed. After multiple exposure tests in harsh weather areas across the country (think snow country, the sunny southeast and extreme mountain locations), Ultra-7 stands out as THE top-of-the-line, long-lasting finish.
The secret behind Ultra-7’s durability is its state-of-the-art resin that creates a flexible and tough seal on your home’s logs. Perhaps more importantly than the seal’s strength, the resin also ensures that the seal is continuous, providing protection from holes and gaps that might otherwise develop with a lower-quality finish. In addition, it has an impressive and unsurpassed adhesion to wood, ensuring industry-leading longevity.
Ultra-7 has proven to be much more resistant to UV degradation, color fading and adhesion loss, resulting in a long-lasting, vibrant color for your log home. And just like all Lifeline finishes, the water-resistant film breathes (just like a Gore-Tex® clothing treatment) to allow trapped moisture to evaporate from your logs.
We’re so confident in the performance of our Ultra-7 that we’re offering it with a 5-year warranty against UV exposure when applied to bare wood and covered with Lifeline Advance clear topcoat and then a maintenance coat of Lifeline Advance during the third year.

Perma-Chink Stain Calculator
Measured Square Footage
Take each wall and multiply length x height. Example 40' long x 10' high= 400 sq. ft.
Add each wall together 400 + 400 + 250 + 250 = 1300 sq. ft. Example 400 sq. ft. x 4= 1600 sq. ft.
For each of your gable ends (the triangles) use Base x Height/2
Example 30' x 15' = 450'/2 = 225 sq ft. Add all areas together.
Adjust for Type of Log
A round log has a different surface area than a flat timber. We must account for the curvature and size of the log so we don't end up short on stain. Select your log type
Most maintenance coats are done with one coat, often clear. If you plan to add a coat of color and a clear, feel free to ask one of our specialists for some advice.
Rough logs will take more stain than smooth logs. If your logs are rough, check off the box and it will calculate based on a rough surface.
Note: All calculations are estimated. Actual coverage will vary based on surface condition, species and moisture content.
