S-100 Finish Remover is an environmentally friendly water-based solvent that removes many oil and water-borne finishes from logs, siding, and decks. Perma-Chink Systems developed a finish remover using new technology originally developed for removing paint from aluminum aircraft surfaces.

Supplied as a ready-to-use gel, it is easily applied with a short bristled brush, paint roller, or airless sprayer. Within a few minutes it begins to soften the finish and since it is a gel, it stays wet and active for a fairly long period of time. Once the finish has sufficiently softened, it can be removed by simply pressure washing.
