Easy Steps for Exceptional Results:
- Preparation: Clean and brighten the surface thoroughly using SEAL-ONCE Multi-Surface Cleaner and All Wood Brightener.
- Wet-on-Damp Application: Apply the first coat using a synthetic brush, roller, or sprayer, ensuring even coverage with back brushing. Follow with a second coat within 20–30 minutes or less. The product can also be tinted with SEAL-ONCE Tint, available in 9 colors.
- Drying Time: Drying Time: Rain-ready in 4 hours, and fully cured in 24-48 hours.
- Maintenance: Reapply as needed to maintain optimal protection and color vibrancy.
With its clear finish, CLEAR WATERPROOFER lets wood age naturally, developing a rich silver-gray finish over time while remaining strong, water-resistant, and protected from decay, delivering up to 4 years of protection.
MARINE GRADE Premium Clear Wood Sealer & Semi-Transparent Wood Stain:
Recommended for: Docks, decks, fences, siding, and more including wood surfaces near water.
Why Choose MARINE GRADE?
Engineered for all environments, including the harshest high-moisture areas and locations near open water, MARINE GRADE Premium Wood Sealer and Stain provide unparalleled waterproofing and protection. Its clear wood sealer enhances the wood's natural beauty, allowing it to age and gray gracefully, and doubles as an independent end-grain sealer. The semi-transparent stain, enriched with trans oxide pigments, delivers a rich, oil-like finish while resisting abrasion.
Both the clear sealer and stain are water-based, ultra-low VOC, and eco-friendly. They guard against water decay and create a flexible, breathable barrier that allows moisture to evaporate while enabling the wood to expand and contract with changing weather conditions.

- Preparation: Clean and brighten the surface thoroughly using SEAL-ONCE Multi-Surface Cleaner and All Wood Brightener.
- Wet-on-Damp Application: Apply the first coat using a synthetic brush, roller, or sprayer, ensuring even coverage with back brushing. Follow with a second coat within 20–30 minutes or less.
