Waterbased, natural-effect, stain resistant water and oil repellent. It is applied indoors and outdoors for the stain-resistant treatment of terracotta and brickwork, stone, marble and unpolished granite, grit and cementitious composites. It reduces the absorption of aqueous, oily and greasy substances. Suitable for food contact, it can be used on all floor and wall surfaces, worktops, kitchen and bathroom counters. Non film-forming, it does not alter the original colour or breathability of the material. NATPROT is ready to use. Apply at least 12 to 24 hours after washing (or treatment with deep penetrating water repellent) on clean, dry or evenly moist material in one or two coats with a brush, cloth or wax spreader, wetting the surface evenly. After drying (1 – 2 hours), any subsequent coat can be applied. After at least 4-6 hours, any finishing products can be applied. Approximate consumption: 10 sqm/1 litre. Avoid application on very hot or very cold surfaces (> 35°C or < 5°C).
