Nutech NuCourt Fill Coat – High Build Sports Surface Leveling Sealer
Nutech NuCourt Fill Coat is a high-solids, water-based acrylic build coat designed specifically for levelling surface inconsistencies less than 20mm deep on asphalt and concrete hard sports surfaces. Applied prior to finishing with NuCourt Pro Coat or NuCourt Roll Coat, it creates a smooth, level foundation that eliminates low spots and prevents water ponding on tennis, basketball, and netball courts.
Formulated for all-weather durability on both interior and exterior substrates, NuCourt Fill Coat is low VOC (<2%), easy to apply using a squeegee or broom, and contains built-in resistance to bacteria and mould to preserve court integrity.

Colour accuracy disclaimer: We have taken care to display the most accurate visuals of our products. However, we are not responsible for the colour accuracy of the device you are viewing our swatches on. These variations arise due to different computer monitors and devices (make, model and technology, as well as resolution, contrast and brightness control settings) in much the same way a scan will differ from an original image and a colour photocopy. Furthermore, coatings can exhibit variation in perceived colour depending on gloss level and application method. If you require a very specific colour match, please make your selection via actual swatches and colour boards available at our showroom.
