PART 3 – EXECUTION

3.1   INSPECTION

A. Inspect concrete or asphalt substrate for dryness. Report any discrepancies to general contractor.

B. Surface of substrate shall be cleaned by general contractor as required.

C. Surfacing contractor to approve site and surface conditions prior to proceeding with application of any coatings.

PREPARATION

A. New Concrete

1. Concrete surface to have light broom finish.

2. The workmanship of other contractors including the sub-base shall be level and compacted. The field dry density shall be a minimum of 95%. The concrete base must have a maximum deviation of 1/8 inch below a 10-foot straight edge when measured by any random path.

3. New concrete shall be cured for a minimum of 30 days before proceeding.

4. All surfaces shall be checked to ensure a level surface. The surface shall be flooded with water, any area that retains 1/8” of water in depth after 20 minutes should be leveled with the approved product. All cracking should be filled with the correct sealant.

5. Surface cleaning – All surfaces must be clean, dry, and free from any bond inhibiting contaminants and foreign residue. Pressure-wash the surface to remove any residues. The surface area should also be scraped and then brushed with a broom. When an acid wash is required follow the manufactures instructions thoroughly, wash area with water using a stiff bristle broom.

6. The polyethylene vapor barrier application shall be applied by additional contractors. The application of the barrier shall be installed preceding any cables or steel. The vapor barrier shall be applied at a minimum of 6-mil and where overlap is required or at any taped joints a minimum of 6 “. Once the installation is completed do not allow any traffic (including vehicular) onto the surface.

B. New Asphalt

1. The workmanship of other contractors including the sub-base shall be level and compacted. The field dry density shall be a minimum of 95%. The asphalt base must have a maximum deviation of 1/8 inch below a 10-foot straight edge when measured by any random path.

2. New asphalt shall be allowed to cure for a minimum of 30 days before proceeding.

3. All surfaces shall be checked to ensure a level surface. The surface shall be flooded with water, any area that retains 1/8” of water in depth after 20 minutes should be leveled with the approved product. All cracking should be filled with the correct sealant.

3.3 INSTALLATION

A. Primer Coat: Must be used when installing Laykold Masters 8 system over new concrete substrates where RH value exceeds 75% according to ASTM F 2170. Laykold Epoxy Concrete Primer is mixed by pouring the “B” component into the “A” component and mixing using a low speed jiffy mixer (400 to 600 rpm) for 2 minutes. Scrape down the sides of the bucket and mix for an additional minute. Do not incorporate air when mixing. Spread the mixed primer on the substrate using a high-quality, medium nap roller to achieve a total coverage of approximately 0.025 gal/yd2 (0.12 kg/m2 – 360 ft2/gal). The working time for Laykold Epoxy Primer is approximately 40 – 50 minutes and is reduced in high temperatures. Lightly broadcast 40 to 60 mesh silica sand onto the wet primer at the rate of 5 pounds per 100 sq. ft. (0.24 kg/m2) to create a rough texture. Allow 5 to 7 hours drying time before proceeding

B. Patching: Once the surface has been thoroughly cleaned and is free of all loose material, dirt, or dust, the court shall be flooded and allowed to drain a minimum of 20 minutes and a maximum of 1 hour. Any area that holds water (birdbaths) in a depth greater than 1/8 inch shall be outlined and patched.

1. Surface Leveling: Birdbaths shall be leveled using a Laykold Acrylic Deep Patch court patch binder slurry. Prime area with a 50/50 mixture of Laykold Acrylic Deep Patch and water. Primer shall be brushed into place and allowed to dry prior to patching. Patch mix shall consist of Laykold Acrylic Deep Patch, 50-mesh sand and Type 1 Portland Cement. Mix as per manufacturer directions.

2. Crack Filling: Cracks shall be cleaned, primed, and filled using Laykold Acrylic Resurfacer if cracks are 1/16 inch or less. If greater than 1/16 inch, Laykold Acrylic Deep Patch court patch binder slurry should be used to fill cracks. Mix as per manufacturer’s directions. Refer to Laykold Deep Patch technical data sheet for additional mixing details and application instructions for filling various sized cracks.

3. All areas that are repaired/leveled/corrected using a court patch binder mixture shall be allowed to fully cure and then ground smooth and level with the substrate by stone or an acceptable mechanical method.

C. Install Laykold Masters 8 system according to guidelines provided.

3.4 PROTECTION

A. Cure Time. No traffic or other trades shall be allowed on the surface for a period of one week following completion to allow for complete and proper cure of the finish.

B. Other Trades. It is the responsibility of the general contractor to protect the surface from damage by other trades before acceptance by the owner or the owner’s authorized agent.

C. Do not allow surrounding sprinkler systems to spray water on the newly applied court surface for a period of one week after completion.

D. Do not place any benches, chairs, ball baskets, or any other type of court equipment on the newly applied court surface for a period of one week after completion.

E. Do not allow black-soled shoes, bicycles, rollerblades, etc. on the court surface. Black scuffmarks cannot be removed!

3.5 MAINTENANCE

A. Dirt Contamination.

1. Broom, wash or blow dirt off court on a regular basis.

2. Annual pressure washing of court surface is recommended.

3. Most dirt and stains can be removed with a neutral pH cleaner used in proper dilution. Pre-test cleaner on small area in corner of court.

B. Proper maintenance procedures and housekeeping practices should be performed on a timely as needed basis.
