Essential Slate Sealer Matt Finish - 25L

Essential Slate Sealer Matt Finish is a specialist sealant designed for external natural slate surfaces, producing a matt appearance. The non-toxic, environmentally friendly formula provides outstanding water repellency and stain resistance. This unique formula significantly reduces capillary water absorption without clogging pores or capillaries, thereby reducing the likelihood of organic soiling, moss, and algae growth while allowing the surface to "breathe" and transfer moisture vapour. Coverage varies depending on the surface type but should be up to 15m² per litre per coat. HOW TO APPLY: Preparation : Remove any loose debris from the work surface. Ensure you have adequate personal protection, such as gloves, protective eyewear, a face mask, and appropriate clothing. Cleaning : Ensure the surface is completely clean and dry before application. Use a low-pressure sprayer, roller, natural fibre brush, or sponge for application. Application : For complete coverage, apply two coats of Essential Slate Sealer Matt Finish to saturation. Do not dilute. After 45-60 minutes, the surface should be dry. If rain is forecasted or begins, stop treatment immediately and cover newly treated areas. The surface must remain completely dry for the first 6 hours after application. PLEASE NOTE : Essential Slate Sealer Matt Finish may cause colour changes on some surfaces; always test the product in an unnoticeable area before using it. Use masking tape to protect surfaces that are not to be sealed. This product is not recommended for use on highly polished, ceramic/glazed, dense, or non-porous surfaces.
