StoneCare4U Essential Matt Finish Slate Sealer 5L 2 Pack

Protect your natural slate surfaces with StoneCare4U Essential Matt Finish Slate Sealer, a high-performance, quick-drying formula designed for lasting protection. This 5L two-pack sealer is perfect for external natural slate, and also works on porous stones like sandstone and limestone. Its attractive matt finish provides excellent water repellence, preventing efflorescence, algae, and green growth, creating a self-cleaning surface that reduces maintenance. For best 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. Don't dilute! Allow 45-60 minutes drying time between coats. Stop application immediately if rain threatens and protect freshly treated areas, the surface must remain dry for 6 hours post-application. Note: This finish may subtly alter the surface colour—test in an inconspicuous area first. Protect unsealed areas with masking material. Not suitable for polished, ceramic, glazed, dense, or non-porous surfaces. Clean with a mild, pH-neutral cleaner, avoid harsh chemicals. Coverage is up to 15m² per litre per coat, varying by surface type. Remember to wear appropriate safety gear (gloves, eye protection, mask, and clothing) during application.
