Stonecare4U Colour Boost All Stone Sealer 5L

Give your outdoor stone a boost with Colour Boost All Stone Sealer. This sealer creates a long-lasting shield against stains and dirt, enhancing your stone's natural beauty. It works on most exterior natural stone (exceptions apply), including limestone, slate, and granite. Prep is key: Clear away loose debris. Safety first – grab your gloves, eye protection, mask, and appropriate clothing. Let the stone dry completely (at least 72 hours) in dry weather. Apply only when the temperature is between 15°C and 23°C. Application's a breeze: Use a low-pressure sprayer, roller, natural fibre brush, or sponge. Don't dilute! After 20-30 minutes, remove any excess sealer. For best results, apply a second coat 45-60 minutes later. Keep the stone dry during the 72-hour curing process to avoid unsightly white patches. Heads up: This sealer changes the stone's colour and appearance. Test it in an inconspicuous spot first. Protect unsealed areas with masking material. Not for use on Kandla Grey (mid & light grey) sandstone or non-porous surfaces. Post-sealing care is simple: Use a mild, pH-neutral cleaner or a very low concentration of our outdoor cleaner range. Avoid harsh or abrasive cleaners. Coverage varies depending on the stone's porosity. Expect 4-6 sq m per litre on textured and riven surfaces, and up to 15 sq m per litre on smooth, honed, or polished surfaces.
