Enhance the natural colours of all internal stone types with the StoneCare4U Essential Gold Colour Boost Stone Sealer 1L. This formula creates a durable and stain-resistant coating that brings out the beauty of your stone surfaces. It is a highly effective multi-purpose indoor stone sealer that offers excellent sealing and oil and stain resistance to all types of indoor stone surfaces. Suitable surfaces include slate, limestone, granite, quartz, sandstone, travertine, and more. How to apply: Above all, before use, remove any loose debris from the work surface and ensure you have adequate safety wear, i.e. gloves, suitable protective eyewear, face mask and clothing. A small test application in an inconspicuous area before use is recommended. This will indicate the suitability and effectiveness of the product for your surface. Importantly, please make sure the surface is completely clean and dry before applying, apply an even coat with a low-pressure sprayer, roller, natural fibre brush or sponge. Certainly, any excess sealer must be completely removed from the surface after 20 to 30 minutes. Finally, apply a second coat approximately 45 to 60 minutes later. Above all, the stone surface must be kept completely dry throughout the curing process, which can take up to 72 hours. Any moisture or water left on the surface within this time may result in the sealer drying inconsistently, showing white patches which can be hard to remove. Please Note: Areas not to be sealed must be protected with masking materials. It is strongly recommended when using coloured grouts that a stain test is completed before proceeding. This product is not suitable for Kandla Grey (mid and light grey) sandstone.
