Extreme Seal Block Paving Sealer – Ultimate Protection 21.0 kg

Extreme Seal Block Paving Sealer is a single-pack, solvent-based block paving sealer formulated to stabilize jointing sand and protect block paving, concrete setts, and porous stone. The low-viscosity resin penetrates deep into the surface; as solvents evaporate, it binds sand particles, creating an elastomeric joint that resists rutting, weed ingress, and wash-out while leaving a premium clear protective film.

Two finish options are supplied:

1. Matt Look – subtle, natural satin.
2. Wet Look – richer color enhancement and a gentle surface sheen.

Add the enclosed silica sachet for a micro-textured anti-slip paving sealer coat on slopes or commercial walkways. 100% UV absorbers stop yellowing, while the tough polyurethane matrix shrugs off diesel, oil, and de-icing salts - ideal for high-traffic driveways, patios, logistics yards, and retail car parks.

Made in the UK to ISO 9001 standards, Extreme Seal dries touch-free in 3 to 4 hours, enabling two-coat same-day application and rapid reopening of sealed areas.
