StoneCare4U Essential Matt Finish Slate Sealer 5L

Protect your natural slate surfaces with StoneCare4U Essential Matt Finish Slate Sealer, a high-performance 5L sealer designed for lasting protection. This quick-drying formula provides excellent water repellence, preventing efflorescence, green growth, and algae. Its attractive matt finish creates a self-cleaning surface, reducing maintenance. Suitable for porous natural stones like sandstone and limestone, this sealer significantly extends the life of your outdoor surfaces. For optimal results, ensure the surface is clean, dry (allow 72 hours in clear, dry weather), and at a temperature between 13-23°C. Apply two coats "wet on wet" using a low-pressure sprayer, roller, natural fibre brush, or sponge. Do not dilute. Allow 45-60 minutes drying time between coats. Protect unsealed areas with masking material. Stop application immediately if rain is forecast or begins, keep the surface completely dry for the first 6 hours after application. Note: This finish may alter the colour of some surfaces, test in an inconspicuous area first. Clean sealed areas with a mild, pH-neutral cleaner, avoid harsh or abrasive agents. Coverage: Up to 15m² per litre per coat (coverage may vary). Always wear appropriate safety gear (gloves, eye protection, face mask, and clothing) during application. Not for use on highly polished, ceramic, glazed, dense, or non-porous surfaces.
