Sportcoat Fibretex

Scope
Surface cracking of tennis courts is a common problem whose causes are many and varied. For the repair of cracked court surfaces, there are several means of reducing the problem and improving the crack free life of renewed surfaces the most suitable repair method however depending on the cause of the problem. What is probably the most common pattern of cracking, caused by shrinkage of the volume of pavement can be remedied by the use of a textile membrane incorporated in a new surface overlay. Such systems rely on the tensile strength of textile cloth in surface overlays, to retard or prevent reflection of pre-existing cracking in the existing surface through a new surface. The membranes can be installed at various heights in the pavement, from subgrade through to surface coating.

Description
This document describes Fibrertex 2000r a fibreglass woven fabric embedded in a coating system over the existing cracked surface, or surface that may be prone to cracking. It is generally an appropriate treatment for new asphalt or previously coated surfaces which display minor surface cracking. Experienced opinion from the company should be sought prior to specifying Fibrertex 2000r.

SURFACE PREPARATION
Any minor depressions, gouges and uneven areas should be repaired prior to commencing coating, using either SPORTCOAT Crack and Patching compound, or Asphalt Filler Coat depending on the nature of the repair. Deep depressions should be repaired in multiple coats to ensure thorough curing of the patching material. Preparation for the installation of membranes should be meticulous in regard to cleanliness of the surface prior to bonding of the membrane. The surface should be thoroughly sanded and blown off to ensure no nibs, sand, or other loose particles are on the surface. The use a high pressure water cleaner after preliminary cleaning is advisable. N.B. The coating system is not generally intended to be a levelling course, and if a job is correctly constructed little work of this nature should be necessary. In the case of excessive unevenness, poor levels or surface texture, refer to the contract Engineer. The manufacturer should be consulted if required for advice on re-levelling old courts for re-coating. Fibretex 2000 Installation On the thoroughly clean surface, the glass cloth should be cut to length and laid on the surface.

Fibretex Special Binder should then be applied to bond the cloth to the surface. Successive strips of the cloth should be bonded to the surface in a similar manner, lapping one strip over its neighbour as specified until the entire surface is covered Wrinkles and folds in the cloth should be avoided.

fibreduring The dry surface should be thoroughly examined to discover any minor imperfections which should be corrected to avoid blemishes showing through the final Sportcoat surfacing. One coat of Sportcoat filler coat should be applied to the entire area and sanded when dry. The surface should is then ready to receive the normal Sportcoat surface system.

Variations in coverage rates particularly with filler coat are dependent on surface texture of the surface being coated. Other factors include operator experience and prevailing weather during the coating operation. Coating should not proceed when the temperature either falls below 100C. or raises above 350C. or when rain threatens.
