Weather Master Exterior Acrylic Masonry Weatherproof Paint 20L 1.0 kg

Manufactured by Trade Supplies UK

Premium Protection for Exterior Walls

Weather Master Exterior Acrylic Masonry Paint is a high-performance, weatherproof coating designed to protect and beautify exterior surfaces such as brickwork, concrete, render, and stone. It is formulated with premium all-acrylic resins and offers exceptional adhesion, flexibility, and resistance against harsh UK weather conditions. Whether for domestic homes, commercial façades, or large-scale developments, this advanced masonry paint ensures long-lasting performance with a smooth, professional matt finish.

Long-Lasting Weather Resistance

Built to endure heavy rain, wind, snow, and intense sunlight, this masonry paint creates a durable, waterproof barrier that prevents moisture penetration and surface degradation. The formula infuses UV-resistant pigments and elastomeric resins that protect against fading, cracking, and peeling, keeping your property looking freshly coated for years. Its superior elasticity allows it to move with the substrate, reducing the risk of blistering or hairline cracks over time.

Superior Adhesion and Coverage

Thanks to its advanced acrylic formulation, Weather Master Exterior Masonry Paint adheres powerfully to both porous and non-porous surfaces. It can be used on bare masonry, previously painted walls, or repaired render, forming a uniform coating that resists flaking and chalking. Each litre covers approximately 8–10 square metres, delivering exceptional spread and hiding power that minimises labour and material costs.

UV and Colour-Fade Resistance

Enjoy vibrant, long-lasting colour with fade-resistant pigments designed for all weather exposure. From subtle creams and greys to bold modern shades, this paint maintains its tone even under prolonged UV exposure. The rich matt finish enhances architectural detail and ensures that façades retain their aesthetic appeal season after season.

Breathable & Anti-Mould Performance

Unlike traditional solvent-based coatings, Weather Master’s breathable acrylic technology allows trapped moisture and air to escape while blocking rain and dirt ingress. This micro-porous film reduces condensation, helps prevent damp patches, and supports healthy wall conditions. Integrated fungicide and anti-algae protection keep surfaces clean, reducing discolouration, moss, and mould growth.

Easy Application & Quick Drying

With a smooth, creamy texture, this masonry paint applies effortlessly by brush, roller, or spray. Its quick-drying formula allows two-coat applications within a single day, making it ideal for professionals and homeowners. It levels beautifully without streaks or patchiness and offers reliable coverage on new plaster, stucco, or old painted walls.

Drying & Recoat Times (@ 18 °C):

Touch Dry: 2–4 hours
Recoat: 6–8 hours
Complete Weatherproof Cure: 7 days

Eco-Friendly and Low Odour

Formulated with low VOC content and minimal odour, Weather Master Exterior Masonry Paint ensures a safer, more comfortable painting experience. Its water-based composition makes clean-up simple, just rinse tools with warm, soapy water. The low environmental impact also makes it ideal for use in sensitive or populated areas where traditional solvent paints would cause disruption.

Storage & Handling

Store between 5 °C and 30 °C, protected from frost and direct sunlight. Always reseal tins tightly after use to prevent skinning and maintain product quality. Dispose of waste responsibly according to local environmental guidelines.

Safety Information

This product is water-based and low-odour, but it’s recommended in a well-ventilated area. Avoid contact with the eyes and prolonged skin exposure. Keep out of the reach of children and pets. Always wear protective gloves and eyewear when handling large applications. For detailed information, consult the product’s Safety Data Sheet (SDS).

Surface Preparation

Before applying Weather Master Exterior Acrylic Masonry Paint, ensure the surface is clean, dry, and sound. Using a stiff brush or power washer, remove dirt, dust, algae, loose paint, or efflorescence. Repair cracks or damaged render and allow any new plaster or masonry to cure completely. Avoid painting in freezing conditions or when rain is expected within 24 hours.

Priming

Apply a suitable masonry stabilising primer or thinned first coat (mixed with up to 10% clean water) on bare, porous, or powdery surfaces to seal and stabilise the substrate. This step ensures consistent absorption, prevents patchy finishes, and improves long-term adhesion.

Mixing

Stir thoroughly before use to ensure full pigment and resin distribution. For spray applications, dilute with up to 5% clean water to achieve a smooth, even flow. Do not over-thin, as this will reduce film build and protection performance.

Application Methods

Brush: Ideal for cutting in and detailed areas such as corners, edges, and around windows.
Roller: Use a medium-pile roller to maintain a consistent, even film for broad wall sections.
Spray: Suitable for large façades or commercial applications; maintain proper distance for uniform coverage.

Apply two thin, even coats at right angles for the best coverage, colour depth, and weatherproof protection. Avoid heavy build-up or reworking areas that are already drying.

Drying & Curing Schedule (@ 18 °C)

Touch Dry: 2–4 hours
Recoat Time: 6–8 hours
Light Rain Resistance: After 6 hours
Full Cure: 7 days

Ensure adequate ventilation during drying. Cooler or damp conditions will extend the drying time.

Curing & Reopening

Allow freshly coated surfaces to remain dry and undisturbed for the first 6–8 hours. Protect from rain or condensation during early curing. The surface becomes fully weatherproof after seven days of normal drying conditions.

Clean-Up

Clean brushes, rollers, and tools immediately with warm, soapy water. Do not allow paint to dry on equipment. Dispose of leftover material and wash water responsibly according to local environmental guidelines.

Maintenance Tips

Inspect painted surfaces annually for signs of wear, algae, or dirt. Clean gently with a mild detergent and soft brush to preserve appearance. Recoat every 8–10 years to maintain long-term protection and colour vibrancy.
