Interior Color Coats and Topcoats

Last modified on Monday, 01 January 2026 23:48

For years, Lifeline Advance™ Topcoats have been an essential part of our exterior finish systems. In addition to extending the life of the finish, Advance helps keep exterior wood surfaces cleaner by reducing the buildup of dust and dirt, making routine maintenance and washdowns much easier.

That’s because Advance is engineered specifically to perform as a true topcoat. Unlike many “clear” products on the market, it isn’t simply a non-pigmented version of a Lifeline™ stain. Stains are formulated for maximum color retention and strong adhesion to bare wood, while a clear topcoat must meet a completely different set of performance demands. That’s why we use an entirely separate formulation to deliver the durability, cleanability, and long-term protection you need from a high-performance topcoat.

For interiors, we follow the same approach: A pigmented finish designed for adhesion and color fastness, covered with a clear topcoat specially formulated for protection. Let’s go through the options homeowners have to best achieve their desired look.

Choosing a Pigmented Interior Stain & Clear Topcoat

The same concept applies to our Lifeline Interior stains as well. Acrylic Gloss and Satin (G/S) and PCS Clear ShieldGloss and Matte (G/M) are completely different formulations than Lifeline Interior.

Lifeline Interior, Lifeline Accents, and Prelude™ use a polymer system that provides distinct adhesion advantages when applied to bare wood. However, if these products are left exposed without a protective topcoat, they can be more susceptible to dirt pick-up and often making the surface harder to keep clean over time.

When topcoated with Acrylic G/S or Clear Shield G/M, the finished surface becomes far more resistant to dirt and grime. And because the topcoat creates a smooth, slick surface, it can typically be cleaned with much less effort.

Bottom line: Lifeline Interior, Lifeline Accents, and Prelude are strongly recommended to be topcoated with either Acrylic G/S or PCS Clear Shield G/M for the best long-term appearance and cleanability.

The Difference of Interior-Specific Topcoats

Whenever a house is over one or two years old, or you are sure your logs are dry, be sure to obtain samples of both PCS Clear Shield G/M and Acrylic G/S to try. If Acrylic G/S does not result in the smooth, slick surface that you may be expecting, try PCS Clear Shield G/M.

Choosing a Natural Finish on Interior Logs

What if you don’t want a pigmented stain on your interior wood? Do you need to apply Prelude or Lifeline Interior Clear before applying PCS Clear Shield G/M or Acrylic G/S? From a technical and performance standpoint it does not matter, although Prelude does include an additive called UV Boost that will help prevent the picture frame effect that occurs over time. Although UV Boost can be added to Lifeline Interior Clear, Acrylic G/S and PCS Clear Shield G/M, most people prefer not to spend more money than they need to, and using Prelude as a primer on bare interior wood will significantly decrease the amount of more expensive Acrylic G/S or Clear Shield G/M you will require.
