StoneCare4U Essential Matt Finish Slate Sealer 25L

Protect your natural slate surfaces with StoneCare4U Essential Matt Finish Slate Sealer, a high-performance, quick-drying formula designed for lasting protection. This 25L sealant 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 minimizes maintenance. For best results, ensure the surface is completely clean, dry (allow 72 hours in dry weather), and at a temperature between 13-23°C before application. 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. Stop application immediately if rain is forecast or begins, protecting freshly treated areas until completely dry (6 hours minimum). Note: This finish may subtly alter the surface colour, test in an inconspicuous area first. Protect unsealed areas with masking material. Not for use on polished, ceramic, glazed, dense, or non-porous surfaces. Clean with a mild, pH-neutral cleaner. Avoid harsh or abrasive agents. Coverage: Up to 15m²/L per coat (coverage may vary). Always wear appropriate safety gear (gloves, eye protection, face mask, clothing.
