Overview

Bedec Extra-Flex Masonry Paint is a high-performance, elastomeric coating designed for exterior walls. Its flexible, microporous formula delivers a smooth, professional finish while bridging hairline cracks to prevent the common issues of flaking and peeling seen with traditional masonry paints.

Formulated with a modified acrylic blend, Extra-Flex expands and contracts with the building, providing long-term durability in all weather conditions. Certified as an anti-carbonation coating, it offers superior protection against moisture, weathering, and structural movement.

Suitable for both new projects and renovation work, Extra-Flex can be applied to a wide range of masonry surfaces, including previously painted walls (with suitable preparation). Manufactured in the UK, it remains a trusted choice for professional and DIY applications alike.

Preparation

For the best results always thoroughly prepare the surface. Ensure the surfaces to be painted are clean dry and free from dust, dirt, grease, and wax.

• Remove any loose, flaking, or defective paint.
• Treat algae, moss, or fungal growth with a suitable fungicidal wash before painting.
• On untreated render, plaster, brickwork, or any porous substrate, thin the first coat with approximately 30% clean water to ensure proper penetration.
• Where there is a risk of staining (extractive discolouration), apply Bedec Stain Block before painting.
• Always test a small area first to check for staining before proceeding with full application.
• Large cracks: Cut out and repair with a flexible exterior filler, ensuring a smooth finish.
• Hairline cracks: Apply Extra-Flex directly into the cracks and feather out to blend with the surrounding surface. One or two additional coats may be required to fully bridge the crack.

Proper preparation is essential for durability and performance, taking extra care at this stage ensures a smooth, long-lasting finish.

Application

We always recommend testing a small inconspicuous area to ensure you are happy with the finished results. Please be aware colours can vary on screens.

• Ensure all cracks are properly treated and the surface is clean, dry, and sound before painting.
• Apply two to three full coats of Extra-Flex over the entire area for maximum protection and durability.
• Suitable for application by brush, roller, conventional spray, HVLP, or airless spray.
• Stir thoroughly before use and confirm the colour is correct prior to application.
• Do not apply at air or surface temperatures below 10°C.
• Avoid painting in foggy conditions or if rain is likely before the coating has fully dried.
• On sealed surfaces, apply two to three coats, allowing each coat to dry completely before applying the next.
• Apply evenly and avoid over-spreading, as this will reduce performance.

Aftercare & Storage

Ensure to clean the rim of the paint tin and firmly replace the lid before storing in a cool , dry area that will protect the paint from low temperatures. Do not store in a shed or by hanging on a hook.
