Extreme Roof Tile Paint and Sealer for Durable Protection 20.0 kg

Q: What types of roof tiles can this paint be used on?

It is designed for porous surfaces such as concrete roof tiles, clay tiles (excluding delicate rosemary types), fibre-cement sheets, artificial slate, and sound masonry parapets.

Q: Does the product need a primer before application?

No primer is required. The advanced acrylic formula penetrates and bonds directly to porous tiles, ensuring strong adhesion and long-lasting protection.

Q: How many coats are recommended for best results?

Two thin coats are recommended to achieve full waterproofing, vibrant colour depth, and a uniform satin finish that resists cracking and fading.

Q: How quickly does it dry between coats?

At around 18 °C, the first coat is typically touch-dry within 2–4 hours and ready for recoating within the same timeframe, allowing most roofs to be completed in a single day.

Q: Is the coating fully waterproof once dry?

Yes, once cured it forms a breathable, waterproof barrier that repels rain while allowing vapour to escape, protecting the roof from moisture damage and moss growth.

Q: Will it help prevent moss and algae regrowth?

By sealing micropores and reducing water absorption, the coating creates a surface that discourages moss, algae, and lichen from re-establishing.

Q: Is it UV-stable to resist colour fading?

The paint is engineered with UV absorbers that lock in colour and protect against sun bleaching, keeping roofs looking fresh for years.

Q: Can it be applied with a sprayer as well as a brush or roller?

Yes, it can be applied by brush, medium-nap roller, or airless sprayer. For spraying, you may dilute up to 5% with clean water for smoother flow if needed.

Q: What is the average coverage per litre?

Coverage is typically 4–6 m² per litre per coat, depending on tile texture and porosity. Ordering enough paint in one batch ensures colour consistency across the roof.

Q: How long before the roof can be walked on after painting?

Foot access with safety planks is possible after about 24 hours. Full weatherproof curing takes around 7 days for maximum durability.

Extreme Paints Roof Tile Paint & Sealer is a premium, quick-drying acrylic roof coating formulated to revive faded concrete, clay, and fibre-cement roof tiles while creating a breathable, waterproof barrier. Designed to withstand the UK’s harsh climate, this advanced polymer anchors securely into porous tile surfaces without the need for a separate primer, ensuring strong resistance to cracking, flaking, and blistering.

Engineered with UV absorbers, it locks in colour and prevents sun fade, while its flexible satin film expands and contracts with seasonal temperature changes to prevent premature failure. Sealing micropores helps block water ingress that encourages moss, algae, and lichen growth, yet remains vapour-permeable so trapped moisture can escape critical for long-term roof integrity.

Made in the UK under ISO 9001 quality controls, it is available in 5 L, 10 L, and 20 L packs, providing a reliable and long-lasting solution for roofers, property managers, and homeowners seeking to enhance curb appeal and extend roof life with minimal downtime.

Suitable Substrates

Concrete roof tiles: Durable and commonly used for residential roofing, providing longevity and strength.
Clay roof tiles (except delicate rosemary type): Traditional, natural clay tiles known for their aesthetic appeal and weather resistance, excluding the fragile rosemary variety.
Fibre-cement sheets: Versatile building material made from a mix of cement and fiber, suitable for roofing and siding.
Artificial slate and asbestos cement: Synthetic alternatives to natural slate, with asbestos cement being an older material now largely phased out due to health risks.
Sound masonry parapets: Structural elements that provide safety and aesthetic value at roof edges, designed to be solid and stable.

Not suitable for plastic, composite, or resin-bonded synthetic tiles: These materials are incompatible due to weight, bonding, or structural issues.

Available Colours

Red • Charcoal • Black • Mid Grey • Terracotta • Brown • Dark Green
(Custom BS/RAL hues available for bulk orders of ≥100 L.)

Artificial slate & parapet masonry: enhances aesthetics while sealing against rain penetration.
Outbuildings & garages: extend roof life and reduce moss and algae growth.

This roof tile paint is widely used by roofing contractors, property managers, landlords, and homeowners looking for a cost-effective roof renovation without the expense of full replacement.

Application Instructions

1. Surface Preparation

Biocidal cleaning: Treat the roof with a biocidal wash to kill moss, algae, and lichens.
Pressure wash: Thoroughly pressure-clean to remove all dirt, growth residues, and loose material.
Drying: Allow the roof to dry fully (minimum 24–48 hours).
Repairs: Replace broken or cracked tiles, and repoint mortar along ridges if needed. Ensure the surface is sound and dust-free before painting.

2. Mixing

Stir the paint for two minutes using a paddle mixer to ensure pigments are reincorporated and consistency is achieved. Pour the paint into trays or spray units. Thinning is only necessary if required for spray application.

3. First Coat

Apply by brush, medium-nap roller, or airless sprayer, starting from the ridge and working downward to prevent overspray onto cleaned areas.
Keep coverage even and thin to allow proper penetration and bonding.

4. Second Coat

Once the first coat is touch-dry (typically 2–4 hours at 18 °C), apply a second coat at right angles to the first.
Two thin coats will achieve ~50 µm DFT (dry film thickness), ensuring long-term waterproofing and UV stability.

5. Curing & Reopening

Protect coated surfaces from rain for at least 4 hours.
Foot access (boards/planks only) is permitted after 24 hours.
Full waterproof performance and chemical resistance are achieved after 7 days.

6. Pro Tips for Best Results

Avoid application during frost, heavy dew, or direct intense sunlight.
Mask off windows, gutters, and glass to prevent overspray.
Work systematically across roof pitches to maintain uniform colour.
Always order the full paint volume in one batch to ensure shade consistency.

7. Clean-Up

Wash rollers, brushes, and spray equipment with warm, soapy water before the coating dries.
Dispose of waste responsibly in line with local environmental regulations.
