Extend the lifespan of your brickwork and conquer moisture with StoneCare4U Essential Brick Waterproofer. This high-performance, deep-penetrating masonry cream delivers exceptional water repellency, creating a robust barrier against damp penetration for up to 20 years-far surpassing the effectiveness of standard paints and coatings. Suitable for brick, stone, and most unprotected masonry, it maintains the original dry appearance of the substrate while providing long-lasting protection. The formula works by filling porous voids without blocking them, allowing the surface to breathe and release trapped moisture. This easy-to-apply cream offers effective protection against flooding and boosts energy savings through improved thermal efficiency, especially beneficial for older properties prone to costly dampness. For hassle-free application, simply remove loose debris, wear appropriate safety gear (gloves, eyewear, mask, clothing), and ensure a minimum temperature of 10°C. A test application in an inconspicuous area is recommended before full application to a clean, dry surface. Apply generously using a low-pressure sprayer, roller, or natural fibre brush, one coat usually suffices, though porous substrates may require a second. Do not dilute. Drying time is typically 30-90 minutes, but avoid application if rain is forecast within 24 hours. Note: While colourless when cured, slight darkening may occur on some substrates-always test first. Protect unsealed areas with masking material. Coverage: 5-10m² per litre per coat (depending on surface texture and porosity). Size: 3L.
