PREPARING AN ASPHALT
SURFACE COURT

NEW ASPHALT COURTS

New asphalt courts must be completely cured (minimum of 3 weeks) prior to application of GENKEM SPORT SURFACE systems.

Once the surface is clean, check the pavement for “birdbaths” by flooding it with water. Allow court to drain for one hour at a minimum temperature of 20 degrees Celsius. If there is any remaining water that cover a R1 coin (South African), that area should be outlined with chalk and filled with patch mix. If the standing water does not cover a R1 piece, it is considered within tolerance and will evaporate within a reasonable time. Re-flooding and patching may be necessary until birdbaths are properly minimized. Use a blower to remove all dust. Surface is now ready for application.

IMPORTANT:

  • Do not mix more material than will be used in 45 minutes.
  • It is imperative to scrape off any old coatings that may be flaking or peeling.
  • Check for “birdbaths” by flooding the surface and make any corrections as in new work procedure. Minor cracks must be cleaned out and repaired with a suitable crack repair material.
  • Surface must be clean and free of all dirt and other foreign matter before the application of any coatings.
  • Use a solution of 1 cup of HTH or similar chlorine and 1 Tablespoon liquid hand detergent to 3.7 litres of hot water to wash away mould, fungus and mildew. Apply liberal amount of solution to the surface with a deck type scrub-brush, allow this to remain on the surface for 5 minutes, scrub briskly with brush, then flush completely with water. When all repairs are completed and surface has been cleaned, the surface is ready for coating to be applied.
  • We recommend you consult an approved applicator should you have any queries regarding preparation.
EXISTING ASPHALT COURTS

Existing asphalt courts needs to be clean and free of all foreign matter such as oil, grease, dirt and other debris. Use a high-pressure cleaner.  Removal of grease and oil requires the use of a strong detergent. After using detergents, it is important to completely flush the surface with water. If oil or grease has softened the pavement, it is necessary to remove the damaged asphalt and repair it with a suitable patch.
