The Quarter System

The quarter system refers to the rough thickness of a board in 1/4″ increments.
Rough thickness refers to the thickness of a board before it was surfaced, or planed. For example, a 4/4 board was 1″ thick before it was surfaced.

Fire & Flame Retardant

Product can be applied to Teak that protects exterior and interior application such as flooring, decking, paneling that is a water-base Post-treatment fire retardant and wood preservative. Non-toxic, non-combustible, non-carcinogenic, that bonds with the cellular structure and contains no PBDEs, which are toxic to humans and the environment. Because it does not alter the structural integrity of the wood the way pressure treatment does, it also functions as a wood preservative, dries clear, and can be easily applied.
