Description
Product Overview
PROSOCO 55086-05GAL deck sealant is a high‑performance, water‑repellent coating designed for exterior wood applications. Formulated with advanced polymers, it creates a breathable barrier that allows moisture to escape while preventing water, dirt, oil and organic stains from penetrating the surface. The sealant deepens the natural grain, enhances color, and provides excellent resistance to scuffing, black heel marks and blushing. Suitable for decks, fences, pergolas and any treated wood that requires long‑term protection without trapping moisture.
Usage
This sealant is ideal for residential and commercial outdoor projects. Apply to clean, dry wood after sanding and allow to dry for optimal adhesion. Perfect for new deck installations, refurbishing existing decks, fence maintenance, and any exterior wood structure exposed to weather, foot traffic and spills.

FAQ
Can this sealant be used on previously painted wood?
Yes, as long as the existing paint is fully cured, clean, and sanded to a smooth surface, the sealant can be applied over it for added protection.
How many coats are recommended for optimal performance?
Two coats are recommended. Apply the first coat, allow it to dry according to the label (typically 2‑4 hours), then apply the second coat for maximum durability.
Is the sealant safe for pets and children?
PROSOCO deck sealant is low‑VOC and non‑toxic once cured. Keep the area well‑ventilated during application and allow full cure before allowing pets or children on the surface.
What is the recommended drying time before foot traffic?
Foot traffic can resume after 24 hours, but full cure for maximum chemical resistance may take up to 7 days depending on temperature and humidity.
Does the sealant require reapplication?
For most exterior wood surfaces, reapplication is recommended every 2‑3 years, depending on exposure to harsh weather and foot traffic.
