Application Guide

NuCourt on Concrete Surfaces

• New concrete must be cured for a minimum of 14 days under summer conditions before coating. Any existing coating must be removed before surface preparation as follows.
• The surface of the court must be clean and free of all grease, oil, chewing gum and other foreign matter. Clean the surface with a high pressure water blaster > 2500 PSI. Remove any grease, oil, food or stains with a strong detergent, caustic cleaner or hot water pressure cleaner as required. Flush thoroughly with clean water. After the surface is dry test the surface for porosity. Apply droplets of water and observe. If the water droplets are not immediately and completely absorbed into the concrete the surface is not adequately clean. After degreasing apply a dilute hydrochloric acid solution (1 part acid to 15 parts clean water) by broom over the whole surface. Leave for several minutes and rinse thoroughly. On very smooth steel trowelled surfaces use a stronger acid solution (1 part acid to 10 parts water). Apply acid in areas of approximately 25-50 square metres.
• Repair all non-structural cracking and any surface damage. Seek professional advice regarding any structural problems, particularly relating to any drainage problems. Any areas where ponding of water occurs deeper than the width of a twenty cent coin (30 mm) will require patching before coating.
• Allow the surface to fully dry. Apply one saturation coat of NuPrime Sealer using rollers or airless spray application at 4 square metres per litre. Do not apply in very hot conditions or mist spray a light coat. It is very important to flood the surface with NuPrime during application.
• If the concrete surface is very rough, patch the surface as required with NuCourt Filler Coat using a 70 Durometer Flexible Rubber Squeegee or two broom technique to obtain a smooth even level surface. Some shrinkage of the filler may occur in thicker films. If the concrete is new and level the filler may not be required. Ensure that all bird baths on the surface are filled to prevent water ponding.
• On a smooth concrete surface you do not need to apply the NuCourt Filler Coat.
• Apply two coats of NuCourt Rollon Formulation TopCoat using a 460mm wide short nap roller to obtain a smooth even level surface. Pour a windrow of coating parallel to the court edge and spread with the roller to obtain an even cover. Do not use a roller tray. Maintain a wet leading edge at all times for the best finish. Work quickly and in cooler weather not in direct sunlight if possible to achieve this. You can add a maximum of 1.5 litres of clean water per 20 litres of Rollon Formulation TopCoat to assist roll application. After adding water always stir thoroughly before applying.
• After applying the first coat allow to dry fully then inspect the surface and scrape off any excess lumps or irregularities before applying the second coat. Do not over dilute.
• Approximately 6 x 20 litres (120 litres) of NuCourt Rollon Formulation TopCoat is required for an average 540 square metre court per coat. If a two colour court is required 60 litres of each colour will be required per coat. Therefore to apply two coats on a 540 square metre court you will need a minimum of 12 x 20 litres (240 litres).
• Always mix thoroughly before application. Do not apply NuCourt products in very hot weather above 35°C or in cooler weather under 18°C. NuCourt products cure very slowly and rain may affect the surface up to 5 days after application.

NuCourt on Asphalt Surfaces

• The surface of the court must be clean and free of all grease, oil, chewing gum and other foreign matter. Clean the surface with a high pressure water blaster > 2500 PSI. Remove any grease, oil, food or stains with a strong detergent and flush thoroughly with water. Allow to fully dry. New asphalt must be allowed to cure for 28 days before coating.
• Repair all non-structural cracking and any surface damage. Seek professional advice regarding any structural problems, particularly relating to any drainage problems. Any ponding of water deeper than the width of a twenty cent coin (30 mm) will require patching.
• Apply one coat of NuCourt Filler using a 70 Durometer Flexible Rubber Squeegee or two broom technique to obtain a smooth even level surface. It may be necessary to apply a second coat of filler subject to the surface conditions. Some shrinkage of the filler may occur in thicker films. Application rates will vary subject to the open or closed nature of the asphalt surface and the application technique. A coverage rate between 2 and 3.3 square metres per litre will be required per coat. Between 160 and 280 litres of filler are required for an average 540 square metre court.
• Apply two coats of NuCourt ProCoat TopCoat using a 70 Durometer Flexible Rubber Squeegee or two broom technique to obtain a smooth even level surface. Pour a windrow of coating parallel to the court edge and spread with the applicator to obtain an even cover by walking in the direction of the windrow and then reversing direction. Do not overwork areas and always maintain a wet leading edge. After the coating is dry, inspect the surface and scrape or grind off any excess lumps or irregularities before applying additional coats. Apply an even downward pressure and avoid leaving thick film sections on either side of the applicator. If using a two broom method spread the coating with a stiff bristle broom and then follow up with a soft bristle to obtain a smooth and even finish. Broom application usually uses 10% more coating material than squeegee application, however on undulating surfaces squeegee application will not be suitable. A coverage rate between 3.4 square metres per litre is recommended. 160 litres of NuCourt ProCoat TopCoat is required for an average 540 square metre court per coat. If a two colour court is required 80 litres of each colour will be required for each topcoat.
• When using the Rollon Formulation topcoat system apply with a 460mm wide short nap roller. Pour a windrow of coating parallel to the court edge and spread with the roller to obtain an even cover. Always maintain a wet edge. Approximately 120 litres of NuCourt Rollon Formulation TopCoat is required for an average 540 square metre court per coat. If a two colour court is required 60 litres of each colour will be required for each topcoat.
• In very warm weather up to 1.5 litres of cold clean water may be added per 20 litres of NuCourt Filler, ProCoat TopCoat or Rollon Formulation TopCoat to slow the rate of drying. Mix thoroughly before application. Do not apply NuCourt products in very hot weather above 35°C or in cold weather under 18°C. NuCourt products cure very slowly and rain may affect the surface up to 5 days after application. Avoid application under 15°C.

Recoating NuCourt

• The existing acrylic surface must be stable with no signs of delamination. Remove all loose or damaged existing coating to expose a stable asphalt or concrete surface.
• The surface must be clean and free of all grease, oil, chewing gum, silicon and other foreign matter. Clean the surface with a high pressure water blaster > 2500 PSI. Remove any grease, oil, food or stains with a strong detergent and flush thoroughly with water. Allow to fully dry.
• Repair all non-structural cracking and any surface damage. Seek professional advice regarding any structural problems, particularly relating to any drainage problems. Any ponding of water deeper than the width of a twenty cent coin (30 mm) will require patching. Where the existing coating has been removed patch the surface using NuCourt Filler Coat. Several coats may be required to achieve a level surface.
• Apply two coats of NuCourt ProCoat TopCoat using a 70 Durometer Flexible Rubber Squeegee or two broom technique to obtain a smooth even level surface. Pour a windrow of coating parallel to the court edge and spread with the applicator to obtain an even cover by walking in the direction of the windrow and then reversing direction. Do not overwork areas and always maintain a wet leading edge. After the coating is dry, inspect the surface and scrape or grind off any excess lumps or irregularities before applying additional coats. Apply an even downward pressure and avoid leaving thick film sections on either side of the applicator. If using a two broom method spread the coating with a stiff bristle broom and then follow up with a soft bristle to obtain a smooth and even finish.

Pour a windrow of coating parallel to the court edge and spread with the roller to obtain an even cover. Always maintain a wet edge. Approximately 120 litres of NuCourt Rollon Formulation TopCoat is required for an average 540 square metre court per coat. If a two colour court is required 60 litres of each colour will be required for each top coat.
• In very warm weather up to 1.5 litres of cold clean water may be added per 20 litres of NuCourt Filler, ProCoat TopCoat or Rollon Formulation TopCoat to slow the rate of drying. Mix thoroughly before application. Do not apply NuCourt products in very hot weather above 35°C. In cold weather under 18°C. NuCourt products cure very slowly and rain may affect the surface up to 5 days after application. Avoid application under 15°C.

Line Marking Paint

To apply two coats of NuCourt Line Marking requires 4 litres per colour. For example, if a multi use court has basketball, netball and volley ball lines 4 litres of white, yellow and red will be required. The two coats should be applied within one hour to enable easy removal of the masking tape. Between 6 and 8 rolls (50m) of masking tape will be required per set of lines. Remove masking tape immediately after applying the second coat.
