Olympic WaterGuard 1 Gal Acorn Brown Semi-Transparent Wood Stain and Sealer | Waterproofing & UV Defense

Protect and enhance exterior wood with a subtle, lasting finish

OLYMPIC WATERGUARD Semi-Transparent Wood Stain + Sealer is an all-in-one solution that colors and seals exterior wood in a single, ready-to-use coat. The Acorn Brown shade offers a soft, natural tint that lets the wood grain breathe while adding a protective layer against the elements.

Designed for a variety of outdoor surfaces, this product works on decks, fences, siding, railings, outdoor furniture, and other wood—including weathered or previously coated pieces. The semi-transparent color preserves texture and grain, so your wood retains its natural character while receiving waterproofing protection. The finish typically dries within one day, making it easier to plan staining around weekend projects. The water-based formula cleans up with soap and water, reducing mess and odors compared to solvent-based alternatives.

What you may notice in real life is a richer, more even tone that still reveals wood texture. Acorn Brown adds warmth to outdoor spaces, helping boards blend together with a cohesive look without hiding original character. Over time, UV defense helps resist sun fading, while SCUFF GUARD Technology contributes to a tougher surface against light wear from foot traffic or furniture movement. The product is built to deliver durable color for exterior wood keepsakes, decks, fences, and siding across seasons.

Key benefits and practical details you’ll find helpful:

• Ready mix, ready to use semi-transparent stain and sealant in one
• Waterproofing protection for exterior wood surfaces, with a typical dry time of 24 hours
• UV defense helps resist sun fade and color change on sunny days
• Exclusive SCUFF GUARD Technology provides a tougher surface against light wear
• Long-lasting color: protection claims up to 3 years on decks and up to 4 years on fences and siding
• Water-based formulation for easy cleanup and low odor
• Coverage around 250-350 sq ft per gallon, depending on wood texture and porosity

Practical application notes and use cases: on decks, it can deepen a warm, natural tone while preserving grain; on fences and siding, it can create a cohesive, inviting exterior that ages gracefully; and on outdoor furniture, it offers a protective layer that can be refreshed with future coats. Because the finish is semi-transparent, the wood’s texture remains a visual feature rather than a flat surface, allowing you to enjoy the character of your outdoor spaces over time.
