Rust-oleum 337037 Varathane Stain Polyurethane Dark Walnut Qt

Product Description

The RUST-OLEUM 337037 is a water-based stain and polyurethane in one, sold under the Varathane line in a Dark Walnut tone with a semi-gloss finish. This single-product formula applies stain color and a protective polyurethane topcoat in one step, eliminating the need for separate products. It is rated for interior wood finishing and delivers coverage in one coat versus the three coats typically required by traditional stain and poly systems. The formula is reported to be two times more durable than conventional stain polyurethane products. Cleanup requires only soap and water. The quart size suits mid-scale projects handled by finish carpenters, cabinetmakers, and experienced DIYers.

This product is intended for interior wood surfaces including furniture, trim, cabinets, doors, paneling, and decorative craft items. The combined stain-and-finish formula shortens project timelines on residential interior work where color and protection are both required. It is not formulated for exterior use or for surfaces exposed to standing water or heavy abrasion. The water-based carrier provides lower VOC output compared to oil-based stain poly alternatives, making it suitable for use in enclosed interior spaces with adequate ventilation.

Installation Notes

Application is performed by finish carpenters, cabinetmakers, or experienced DIYers using a quality brush, foam applicator, or lint-free cloth. Ensure the substrate is clean, dry, and free of wax, grease, and loose finish before applying. Work in a well-ventilated interior space and allow adequate dry time between inspection coats as directed on the product label. Do not apply over oil-based finishes without proper preparation, and do not thin with solvents — this is a water-based formula.
