6 15ECS-MI-01WA / TCN Page 6 of 10.7 Install net hold-down ring anchors accurately to be plumb and flush with the finished court surfacing..8 Protect the work until final set has occurred. 3.3 ASPHALT PENETRATION COURT.1 Set grade stakes on the court and all around the perimeter..2 Place specified granular and compact to 100% Standard Proctor Maximum Dry Density in accordance with ASTM D698-00ae1. Finished depth of granular shall be as shown on the drawings and details. The granular material will be placed in lifts of no more than 150mm and compacted to specification..3 On the approved compacted smooth granular base, spread 19mm dia. clear stone to a uniform depth of 25mm with allowances for subsequent layers below the established finished grade of the court. This material shall be placed with the assistance of a laser level and hydraulic receiver on the spreading equipment. High and low spots shall be levelled by removing or adding stone and re-rolling..4 After the 19mm dia. clear stone layer has been approved, apply R.S.1 asphalt emulsion at the rate of 0.6 L per m2 and immediately spread 9.5mm dia. HL 3 coarse aggregate to a depth of 16 mm until a uniform gradient has been established.

Check and confirm the surface with a 6 m straight edge..5 After the 9.5mm dia. HL-3 coarse aggregate layer has been approved, remove grade stakes and apply RS 1 asphalt emulsion at the rate of 0.9 litres per square metre and immediately spread 6.4 mm dia. coarse aggregate to a depth of 10 mm until a uniform gradient has been established. Broom in thoroughly until all voids are filled and roll lightly. Check and confirm the surface with a 6 m straight edge..6 After the 6.4 mm clear stone layer has been approved, apply RS-1 asphalt emulsion at a rate of 0.3 litres per square metre and immediately thereafter spread sand at a rate of 2.3 kilograms per square metre. Broom in thoroughly until all voids are filled and no excess sand remains on the surface. Roll lightly..7 After the sand operation has been approved, apply RS-1 asphalt emulsion at a rate of 0.25 litres per square metre and immediately thereafter spread trap rock screenings at a rate of 7.8 kilograms per square metre. Broom with a fine hair broom until the entire area is uniformly covered and perform final light rolling..8 When the traprock has thoroughly set, broom off excess, remove and dispose of all loose material from the court surface, around net posts, fence posts and net anchors and from perimeter concrete pad.

7 15ECS-MI-01WA / TCN Page 7 of 10.9 Thoroughly sweep the courts to remove all dirt, dust and other loose material completely from the surface. Vacuum if necessary..10 Examine the entire court surface for unevenness, irregularities, minor depressions, or excessive roughness. Roll the surface with a tandem steel wheel roller as necessary to achieve a true level surface. Roller must adhere to reservoir weight restrictions..11 Dynamic rollers will not be permitted for compaction..12 After rolling, check surface with a 3m straight edge and mark all depressed areas greater than 3 mm in depth. Patch and level all such areas and around all posts as necessary to achieve the tolerance with the patching mix specified..13 Pay careful attention to the feathering of the edge of the patches so that the patch blends completely with the surrounding surface. All patches shall be finished neat and even to the satisfaction of the City of Toronto s Representative. Allow all patches to dry sufficiently and then roll to ensure evenness with the surrounding surface. Allow patches to set completely before proceeding..14 Temporary Playing Lines: The playing lines on the courts shall be accurately laid out by survey and temporarily marked on the court to ensure coordination with the final court surface. 3.4 GENERAL TACK AND FIBREGLASS INSTALLTION.1 The tack coat material, as specified and mixed with the specified coat application amount of water, shall be applied over the entire surface. Avoid excessive application and or ponding which may cause bleeding through the successive coatings. The fibreglass shall be rolled out into the Plexibond or approved equal and stretched tightly over the entire surface. Adjacent panels shall be overlapped 3 minimum. Wrinkles in the fibreglass membrane shall be corrected prior to application of Acrylic Resurfacer or approved equal. 3.5 FILLER COAT/RESURFACING UNDERLAYMENT APPLICATION.1 Two (2) coats of filler shall be applied over the entire court surface, and only when all areas of the underlying surface are thoroughly cured as per the Manufacturer's specifications..2 The filler may be diluted with clean, potable water. No other thinning agents shall be permitted. Dilution shall be in strict accordance with the Manufacturer's directions. Over dilution shall not be accepted. Silica sand may be added in minor amounts to properly fill all surface voids and even out any surface unevenness.

8 15ECS-MI-01WA / TCN Page 8 of 10.3 The coating shall be applied by broom or squeegee in multiple applications to achieve a total application rate of 40 to 74 litres of undiluted material per 100 sq m of surface area. No successive coat shall be applied until the preceding coat is thoroughly cured..4 Each application of the filler coat shall be permitted to dry thoroughly. The surface, prior to the application of the colour coat, shall have a uniform appearance and be free from ridges and tool marks. 3.6 COLOUR COAT.1 Ensure that net post footings and hold-down rings are installed as detailed and set to Finished court elevation prior to finished coatings or final surfacing..2 Application of colour coat shall be in accordance with the recommendations of the Manufacturer..3 Thoroughly mix colour surfacing material and apply using squeegee, soft haired brooms, short-napped rollers, or a combination of these to obtain a surface of uniform texture, thickness and colour, free from tool marks. Thick films shall not be left on the surface to prevent shrinkage cracks or shiners.4 The colour coat system shall consist of minimum of two applications of the appropriate material specified, diluted as per Manufacturer's specification. The second application shall be at right angles to the previous to achieve a total coverage of surface. Avoid excessive application that would result in cracking and alligatoring. Add sufficient silica sand to produce desired texture. If necessary an additional coat of colour coat without sand shall be applied to reduce or soften the texture to that specified. The finish surface shall be uniform in texture thickness and colour..5 Care shall be taken not to leave any ridges in the material when spreading. If any ridges are left or found, the material will be allowed to thoroughly dry and ridges will be scraped off with the edge of steel trowel. All scrape marks must then be hidden/covered by a subsequent application Provide personnel to protect the finished surface from traffic until thoroughly cured. Any damages or defects occurring as a result of failure to comply with this requirement shall be repaired by the Contractor at no extra cost to the Owner. 3.7 PLAYING LINES.1 Playing lines shall be painted on the courts only after the colour has thoroughly dried. All lines shall be uniformly 50 mm wide, accurately located (± 3 mm) marked, and painted with white line paint. The edges of the lines shall be well defined and sharp.
