Stonecare4U Colour Boost Limestone Sealer 5L

Give your limestone a vibrant new look with Stonecare4U Colour Boost Limestone Sealer. This high-performance sealer protects limestone and other porous stones like sandstone (exceptions apply) and slate from stains, while enhancing their natural colour. Before you begin, make sure the surface is completely dry—allow at least 72 hours of dry weather after cleaning away any loose debris. Work in temperatures between 15°C and 23°C. Apply the first coat using a low-pressure sprayer, roller, natural-fibre brush, or sponge. Don't dilute! Remove any excess sealer within 20-30 minutes. For best results, apply a second coat 45-60 minutes later. Keep the stone dry during the 72-hour curing process. Important: This sealer will change the stone's colour, so test it in an inconspicuous area first. Protect unsealed surfaces with masking material. Not for use on Kandla Grey (mid & light grey) sandstone or non-porous surfaces. Clean sealed areas with a mild, pH-neutral cleaner or a very low concentration of our outdoor cleaner range—avoid harsh chemicals. Coverage: Up to 15m²/litre per coat (coverage varies by surface). Remember your safety gear: gloves, eye protection, face mask, and appropriate clothing.
