Old Masters Gel Stain, Red Mahogany, Half Pint
Old Masters Gel Stain in Red Mahogany, Half Pint, adds oil-based color to prepared interior wood and compatible nonporous surfaces. For practical wood coverage, plan about 19–31 sq ft from this half-pint can, depending on porosity, texture and application. Its thick alkyd formula works on vertical surfaces; test your complete stain-and-clear-finish process first.
Features
- A thick gel supports control on vertical surfaces.
- Works on difficult-to-stain wood such as pine and maple.
- Can update properly prepared existing finishes.
- Gel colors can be intermixed for a tested custom shade.
Best for
Interior wood furniture, trim, cabinetry and compatible fiberglass, primed metal or composition surfaces. Exterior entry or garage doors require a protective exterior clear finish. Manufacturer maple and oak samples are approximate references; your surface affects appearance.

How to apply
- Start with a clean, dry surface free of wax, grease, glue and dirt. Sand wood smooth, repair defects and remove dust with a tack rag or lint-free cloth dampened with mineral spirits. Scuff sand an existing finish and remove dust. Follow lead-dust precautions before disturbing old paint.
- Stir to a uniform consistency. On bare wood, apply liberally with a brush or soft rag, then remove excess along the grain. On fiberglass or composition, work one panel at a time with a firm synthetic brush or lint-free rag, feathering streaks while wet and wiping excess from the brush.
- Let dry about six to eight hours; apply an optional second coat after at least eight hours and only when dry. Ideal conditions are 70–75°F and 35–50% humidity. Temperature, humidity, airflow and excess stain can delay drying.
- Use a compatible clear finish, testing the full process first. The February 2025 TDS directs complete stain drying followed by an additional 24 hours before a water-based finish. Test lacquer compatibility. Exterior doors need an exterior clear finish.
Good to know
DANGER: Flammable liquid and vapor; may cause allergic skin reaction, genetic defects, cancer and fertility or unborn-child harm; prolonged or repeated exposure damages organs; swallowing followed by entry into airways may be fatal. Read the exact manufacturer-code safety sheet, wear its specified protection and keep ignition sources away. Work with adequate ventilation and avoid breathing vapors. Used rags, steel wool and sanding waste can ignite spontaneously: immediately place in a sealed, water-filled metal container and dispose under local fire rules. Do not thin. Mixing Natural Gel Stain can lighten other Gel colors; test proportions.
Questions
