Stormdry XR Mortar 310ml Cartridge x 3 Pack - Express Mortar

This bundle contains 3 packs of Stormdry XR-Mortar (310 ml) - enough to repair 900 cm3 of wall volume or 300 damp-proof course holes. Stormdry XR-Mortar is a semi-flexible, polymer-modified crack filler designed for small-scale repairs to brick & masonry. It seals cracks and damaged pointing to prevent rain penetration and forms a long-lasting, water-resistant barrier once cured. The warm grey mortar is supplied ready-to-use in a 310 ml cartridge for application by standard mastic gun. Suitable for interior or exterior use, it fills cracks between 1 mm and 15 mm wide and can also be used to plug damp-proofing cream holes. It is ideal for repairing weathered mortar joints, reinstating isolated damage or prepping cracks ahead of waterproofing treatments. Apply to clean, pre-raked joints 15-25 mm deep. For cracks wider than 10 mm or for thick applications, build in two layers for better cure & bond. The mortar skins over in 1 day and fully cures within 2-4 days under normal conditions. In cold or damp weather, curing may take up to 14 days. Once surface drying begins, excess can be scraped back and tooled for a neat finish. Keep protected from rain for at least 24 hours post-application. One cartridge fills approx. 100 damp-proof course holes or repairs 300 cm3 of wall volume. Clean tools with water before the mortar dries.
