Product Description
Carbopol Acrylic Roof Coating is a premium, solvent-based acrylic coating that incorporates synthetic fibres to provide a tough yet flexible seamless coating for industrial and domestic roofs. Designed for long-term maintenance, excels in all weather conditions, including damp environments, making it a reliable choice for the remedial repair of leaking roofs.
Features and Benefits for Carbopol Acrylic Roof Coating:
- Damp Weather Application: Can be applied even in wet conditions, resisting water wash-off and curing to form a water-impermeable membrane.
- Fibre Reinforced: Enhanced durability and strength due to the incorporation of synthetic fibres.
- Excellent Adhesion and Flexibility: Bonds well to a wide range of materials including asphalt, bitumen, concrete, brickwork, slates, metals, and plastic guttering.
- Single Coat Application: Simplifies the application process, saving time and effort.
- Ready to Use: No mixing required, making it convenient and easy to apply.
Typical Uses:
- Industrial Roofs: Ideal for maintaining and repairing large industrial roofs, providing a durable and long-lasting solution.
- Domestic Roofs: Suitable for residential properties, ensuring protection against leaks and weather damage.
- Leaking Roofs: Effective for the remedial repair of leaking roofs, even in wet weather conditions.
- Various Materials: Adheres well to a variety of materials including asphalt, bitumen, concrete, brickwork, slates, metals, and plastic guttering.
Fill holes and imperfections with Roofing Mastic, stick down loose felt with Felt Adhesive.
Surface Preparation:
Ensure the surface is free from loose dirt, oil, grease, stone chippings, lichen, moss, and standing water. Treat fungal growth with a fungicidal wash.
Although Carbopol Acrylic Roof Coating can be applied to damp surfaces, dry surfaces will ensure optimum adhesion
Metal surfaces should be wire brushed to remove loose scale or dust.
Fill holes and imperfections with Roofing Mastic, stick down loose felt with Felt Adhesive. Blisters in felt must be cut, dried, re-bonded and sealed.
Priming:
Generally, no priming is needed, but for very porous surfaces, a primer may be used to enhance adhesion.
For most applications Carbopol Acrylic Roof Coating can be applied direct to the substrate without priming. However with very porous surfaces such as concrete or asbestos sheeting, adhesion can be improved by first applying a coat of Bitumen Primer or a stabilising solution.
Application:
Apply to the prepared substrate by brush or roller at the recommended rate of 0.5-1L/m2per coat, ensuring an even coverage free from pinholes. Apply two coats allowing the first to skin before applying the second. The product will fill and bridge cracks up to 3mm wide, but where wider cracks are present these should be covered with a suitable flexible scrim bedded into the coating.
On damp substrates Carbopol Acrylic Roof Coating should first be worked into the surface with a brush or roller to disperse excess moisture and ensure a good bond. Immediately afterwards, further material is then brushed onto the surface.
Cleaning: Clean equipment immediately with white spirit after use.
Storage: Store in a cool, dry place away from ignition sources. Shelf life is a minimum of 12 months in unopened containers.
Q: What is Acrylic Roof Coating and how does it protect my roof?
A: Acrylic Roof Coating is a water-based, flexible waterproof membrane that provides long-lasting protection against UV rays, weathering, and water ingress. It forms a seamless coating that helps extend roof life, reduce heat absorption, and seal minor cracks or imperfections.
Q: What surfaces can I apply the Acrylic Roof Coating to?
A: This coating can be applied to a wide range of roof types, including concrete, bitumen, metal sheets, weathered roofing felt, and previously coated surfaces. Ensure the substrate is clean, dry (or slightly damp), and free from dust, algae, oil, and loose debris before application.
Q: How much coverage does it provide and how many coats are needed?
A: The typical coverage rate is 0.5 – 1 litre per m² per coat, depending on the surface condition and porosity. Two coats are generally recommended for full waterproofing protection. Always allow the first coat to dry completely before applying the second.
Q: How long does it take to dry and when can it be exposed to rain?
A: Under normal conditions (around 20 °C and good airflow), the coating is touch-dry within 4–6 hours and fully cured within 24–48 hours. Avoid applying if rain is expected before the coating has fully dried, as moisture can affect adhesion and finish quality.
Q: What precautions or limitations should I consider before using Acrylic Roof Coating?
A: Do not apply to areas where standing or ponding water occurs.
Avoid application in cold (below 10 °C) or very humid conditions.
Stir thoroughly before use and apply evenly using a brush, roller, or airless spray.
For best results, inspect the roof periodically and recoat every few years to maintain performance.
