Lifeline Interior Semi-Transparent Finish and Sealant
Wood Stain for Interior Surfaces
Enhance the beauty of all your interior wood and seal out household odors and contaminants. Lifeline Interior can be used as a color coat or sealing coat on walls when you want to apply an interior clear coat for additional protection or luster.
Perma-Chink interior log stain breathes, allowing trapped moisture to evaporate. It also unifies the tone throughout the space without overwhelming the natural grain. The addition of UV Boost to the first coat significantly reduces the ‘picture frame effect’ in sun-exposed locations.
Our entire line of interior wood stain colors will not turn yellow. You can apply multiple coats to develop the right color and film thickness. Each option is compatible with our other interior finishes.
Lifeline Interior Available Sizes
Project size and room layout will determine how much is necessary for the job. This wood stain for interior use is available in sample sizes, 1-gallon containers, and 5-gallon pails.
Sample sizes help compare interior wood stain colors under actual lighting conditions. For touch-ups, the smaller size works well. However, larger projects typically need five-gallon pails.

How to Store
Closed containers hold up better over time. Air exposure quickly changes consistency, so keep it in a clean, dry space. Temperature swings can weaken interior log stain, especially between uses.
A shelf inside the home usually works better than a poorly insulated garage. Before re-using, confirm product integrity for best results.
Application Steps
Interior surfaces tend to reveal inconsistencies more clearly, so preparation is critical.
- Clean all surfaces thoroughly and allow to dry
- Apply the wood stain for interior use in thin, even coats using a brush or cloth
- Work with the grain
- Use a consistent application pattern
- Allow the first coat to seal before continuing
Maintenance
Interior surfaces experience wear in different ways. High-contact areas require light cleaning to protect the finish. Occasional touch-ups may be necessary in areas with repeated use. Addressing visible changes early helps maintain a consistent appearance across the space.
