StoneCare4U Essential Matt Finish Sandstone Sealer 5L

Protect your natural sandstone, limestone, and slate surfaces with StoneCare4U Essential Matt Finish Sandstone Sealer. This fast-drying, 5L sealer delivers a durable matte finish that powerfully resists stains and provides exceptional water resistance for long-lasting protection. Its unique formula prevents efflorescence and inhibits algae growth, creating a self-cleaning surface that minimizes maintenance. The environmentally friendly composition offers outstanding water repellency and stain resistance by significantly reducing water absorption without blocking pores, allowing the material to breathe. For best results, ensure the surface is completely clean and dry for at least 72 hours in clear, dry weather before application (13-23°C). Wear appropriate safety gear (gloves, eyewear, mask, clothing). Apply two "wet-on-wet" coats using a low-pressure sprayer, roller, natural fibre brush, or sponge. Do not dilute. The surface will be dry in 45-60 minutes. Stop application immediately if rain threatens and protect freshly treated areas, keep the surface dry for at least 6 hours after application. Test in an inconspicuous area first, as colour change may occur. Protect unsealed areas with masking material. Clean sealed surfaces with a mild, pH-neutral cleaner or a low-concentration outdoor cleaner, avoid harsh or abrasive agents. Coverage: 4-6 sq m per litre.
