Minwax 402140000 Wood Effects Age Accelerator Quart Gray

Product Description

The MINWAX COMPANY, THE 402140000 is a brush-on wood age accelerator formulated to produce a weathered gray appearance on bare wood surfaces. It works by reacting chemically with the natural tannins already present in the wood, creating an aged look without staining or painting over the grain. Sold in a quart container, this product is suited for finish carpenters, woodworkers, and contractors working on interior or exterior wood surfaces where a weathered aesthetic is specified. The chemical reaction-based process means results vary with wood species and tannin content, making application planning an important step before full-scale use.

This product is used on bare, unfinished wood where a naturally aged or weathered gray finish is the design goal. Typical applications include accent walls, barn wood effects, decorative trim, furniture, and architectural millwork. Because the formula relies on the wood's own tannins, species with higher tannin content such as oak, walnut, and cedar tend to produce more pronounced results. Low-tannin species may require a tannin pre-treatment to achieve consistent color. This product is appropriate for both residential and light commercial finish work.

Installation Notes

Application should be performed by finish carpenters, woodworkers, or contractors familiar with wood finishing products. Always test on a small, inconspicuous area of the same wood species before full application to evaluate the tannin reaction and final color. Ensure the work area is well ventilated and follow all safety precautions on the product label regarding skin and eye protection. Do not apply over sealed, stained, or previously finished wood surfaces.
