Extreme Seal Pattern-Imprinted Concrete & Patio Sealer Gloss 20.0 kg

Extreme Seal Pattern-Imprinted Concrete & Patio Sealer is a high-concentrate, solvent-borne acrylic sealer designed to protect and enhance pattern-imprinted (stamped) concrete, exposed-aggregate slabs, block paving, and porous paving stones. The low-viscosity resin penetrates textured surfaces to bind loose colour hardener and fines. 

It locks in decorative detail while laying down a durable, easy-clean gloss film that repels water, oil, dirt, and common automotive fluids. On new or previously coloured decorative concrete, it deepens pattern depth and colour, reviving tired areas and unifying the finish across large driveways and patios.

Choose the Standard version for a rich, clear, or tinted gloss. Where extra grip is required—on slopes, steps, or pool surrounds add the pre-measured silica to create a subtle anti-slip texture without dulling the finish. Formulated and manufactured in the UK under ISO 9001 quality assurance, 

Extreme Seal is tack-free in under five hours, enabling same-day second coats and minimal downtime for homeowners and contractors. The result is a hard-wearing, weather-resistant film that helps resist tyre scuffs, de-icing salts, and everyday staining while keeping decorative concrete easy to maintain.

Suitable Surfaces:

• Pattern-imprinted/stamped concrete driveways and patios

• Exposed-aggregate slabs and decorative concretes

• Concrete patios and walkways

• Block paving, concrete flags/slabs, and porous stone

Not suitable for asphalt or non-porous dense granites. Always test on an inconspicuous area. Texture, age, and porosity affect final appearance and coverage.

Available Colours & Finishes:

• Colours: Mid Grey, Charcoal Grey, Black, Red, Sandstone, Terracotta, Brown, Dark Green, Clear Top-Coat

• Finishes/Variants:

• Standard: clear or tinted gloss sheen

• Anti-Slip: add supplied silica for a micro-textured safety finish

• Custom shades: RAL/BS colours available on orders of ≥ 100 L orders

• Pack sizes: 5 L, 10 L, 20 L

Coverage & Spread Rate:

• First coat: ~ 5 m²/L on porous, patterned, or exposed-aggregate concrete (apply thinly and evenly)

• Second coat: ~ 7 m²/L (substrate already sealed, lower absorbency)

Coverage varies with texture, jointing, and porosity. Over-application can trap solvent and prolong cure.

Drying & Curing Times (@ 18 °C):

• Touch-dry: 3–5 hours

• Recoat: 4–6 hours

• Light foot traffic: 12 hours

• Vehicle traffic: 48 hours

• Full chemical cure: 7 days

Keep sealed areas dry for at least 6 hours after coating. Cooler or humid conditions will extend drying.

Storage & Clean-Up:

• Store sealed between 5–30 °C, away from flames/ignition; reseal between uses

• Clean rollers, brushes, and spray gear immediately with white spirit or standard thinners

• Thinning: Ready-for-use; for spray, thin up to 10% xylene-based acrylic thinner (over-thinning reduces film build)

Finish & Appearance:

Leaves a clear, decorative gloss that enhances colour hardener and pattern depth while helping to dust-proof and waterproof the surface. For high-traffic zones, an optional third clear coat can increase depth and durability, especially on Wet-Look projects.

Batch & Packaging Notice:

For large areas, order the total required quantity in one batch to ensure uniform shade/finish. During peak demand, products may ship in plain tins with a Trade Supplies UK label; performance and specification are identical.

Safety Notice
