Thompson's WaterSeal Multi-Surface Waterproofer Stain — Clear 1 Gallon, UV-Resistant Water Repellent

Thompson’s WaterSeal Multi-Surface Waterproofer Stain (Clear, 1 gallon) is a clear, UV-resistant sealer that preserves and repels water on exterior wood, concrete, brick and masonry while keeping natural texture visible.

Designed for decks, fences, patios and walkways, this one-gallon clear waterproofer stain enhances natural color without hiding surface texture and provides long-lasting protection from moisture and sun exposure. Its advanced polymer formula resists fading and is intended to be simple to apply for DIYers and professionals alike. Use it to refresh older outdoor surfaces or finish new projects with a durable, low-profile protective layer.

How does this product protect different outdoor surfaces?

The formula creates a water-repellent barrier that helps prevent moisture penetration on wood, concrete, brick and other masonry. It does not form a thick film; instead, it soaks in to preserve texture while reducing water-related damage and staining potential.

• Suitable for exterior wood decks and fences to reduce water absorption.
• Works on concrete and masonry to minimize water seepage and superficial staining.
• Clear finish means underlying grain or texture remains visible.
• Advanced polymers increase resistance to UV fading over time.

Will the clear stain change the look of my deck or patio?

The clear formula subtly enhances the surface’s natural tone without masking grain or texture. It provides a slight sheen and enriches color depth while remaining transparent, so the original appearance is maintained rather than replaced.

• Enhances natural color without opaque coverage.
• Does not hide surface texture or wood grain.
• Gives a uniform, low-profile finish across mixed materials.

Is application difficult and what preparation does it need?

Application is straightforward for anyone comfortable with basic exterior painting or sealing tasks. Key to performance is preparing clean, dry surfaces: remove dirt, mildew and loose material, and allow the surface to dry fully before applying the sealer.

• Clean surfaces thoroughly—power wash or scrub as needed.
• Allow surfaces to dry completely before sealing.
• Apply with brush, roller or sprayer according to conditions and coverage guidelines.
• One-gallon size covers moderate areas; check label for coverage rates.

How long can I expect the protection to last and how should I maintain it?

Longevity depends on climate, traffic and exposure; the fade-resistant polymers help extend visual life compared with untreated surfaces. Periodic inspection and reapplication when water no longer beads or color looks dull will keep surfaces protected.

• Resists UV fade for improved seasonal durability.
• Reapply when surface repellency or appearance declines.
• Regular cleaning extends the finish life between coats.

Who is this for: Thompson’s WaterSeal Clear Multi-Surface Waterproofer is aimed at homeowners, contractors and outdoor DIY enthusiasts who want a simple, clear protective coat for wood, concrete, brick and masonry. If you need a low-visibility sealer that preserves texture, reduces water penetration and resists UV fading, this product offers an easy-to-apply option for routine maintenance or finishing new exterior projects.
