Nu-Cryl WRS Extra is a unique hydrophobic oil and water repellent treatment and a terrific stone and masonry sealer that keeps your structure looking as good as new, thanks to its clear application. A non-glossy appearance and resistance to stains means your structure will retain its aesthetic. Not only does the coating repel water, but also reduces the penetration of oil and stains into masonry. This is fantastic news for brickwork exposed to oily or messy environments, whilst offering fantastic protection against weathering, UV, frost damage and organic growth.

For use on dense, low porosity substrates such as polished concrete & GRC and blockwork, marble and terrazzo, and also compatible with concrete surfaces treated with Silane.

Product Use in the Workplace

• Garage - Concrete flooring in garages is a breeding ground for oil, grease and other substances that can leave stains. 
• Shopping centres - Walkways in shopping centres have to contend with enormous amounts of footfall within the course of a year. Each seasonal change brings its own challenges: in the summer, warm chewing gum gets stuck to visitor's footwear and brought inside; in winter, wet mud, dirt and the general humdrum wetness of wintertime is brought indoors, particularly at entrances. There is no footwear dress code for shopping centres, so there will be young kids who have been jumping in muddy puddles and there'll be workmen coming-in to run errands before heading back home, and everything in between. Stain and water repellency is your new friend.
• Paved driveway - A beautifully-laid driveway is as decorative as it is useful. When not being driven, a car needs to be stored somewhere, and on these paved driveways, oil, grease, water and other pollutants drip from the car and leave black and greasy stains on the driveway. Other than being potentially dangerous, it looks unsightly, taking away the appeal of the decorative appearance.

Application

Application by low pressure spray or by brush/roller taking care to avoid any sagging. Application on vertical surfaces should be to full saturation commencing at the bottom and working upwards. One application is normally required, however, on porous substrates a second application may be required. Apply the second application in the same manner immediately after the first application, taking care not to allow the first application to dry out. Do not apply at temperatures below 5°C.  Allow 72 hours to lapse before overcoating surfaces treated with Silane. Shake container well before use. The figures quoted below are average coverage rates and given only as guidance:
