StoneCare4U Essential Matt Finish Sandstone Sealer 5L 3 Pack

Protect your natural sandstone, limestone, and slate surfaces with StoneCare4U Essential Matt Finish Sandstone Sealer. This fast-drying sealer delivers a durable matte finish that powerfully resists stains and provides exceptional water resistance for long-lasting protection. Its unique formula prevents efflorescence and inhibits algae growth, creating a self-cleaning surface that needs less maintenance. The sealer significantly reduces water absorption without clogging pores, minimizing soiling and algae while allowing the stone to breathe. It offers outstanding water repellence and stain resistance. Before application, ensure the surface is completely clean and dry (allow at least 72 hours of dry weather). The ideal application temperature is between 13°C and 23°C. Apply two coats "wet on wet" using a low-pressure sprayer, roller, natural fibre brush, or sponge. Don't dilute! The surface will be dry in 45-60 minutes. Protect freshly treated areas from rain for the first 6 hours. Always test in an inconspicuous area first, as colour change may occur on some surfaces. Mask areas you don't want sealed. Remember your safety gear: gloves, eye protection, face mask, and suitable clothing. For cleaning, use a mild, pH-neutral cleaner or a low concentration of our outdoor cleaner. Avoid harsh chemicals. Coverage is approximately 4-6 sq meters per litre, varying by surface porosity. This pack contains 3 x 5L containers.
