ADVANTAGES

Situations requiring stronger, more durable compositions, where excellent adhesion is critical, where thin screed applications are required or prepared, Impact provides:
1) Unequalled bond strength to a wide variety of substrates including concrete, masonry, brick, glass, metal, wood and polymeric foam products.
2) Superior mechanical strength, tensile strength, flexural strength and impact resistance are significantly improved.
3) Excellent water resistance and abrasion resistance.
4) Unequalled resistance to discoloration on exposure to U.V. light.
5) Superior freeze, thaw resistance and proven long term durability in exterior situations.
6) Good chemical resistance for use in general purpose applications
7) Low Maintenance - no flaking, cracking or peeling. Simple cleaning only required.
8) Player Satisfaction - excellent ball response with consistent bounce.

BUILDING STANDARD

This should comply with the Squash Rackets Association (SRA) Squash Court Specification. Another acceptable standard is the court specification put out by the International Squash Racket Federation (ISRF). In general the SRA standard specification recommends the walls be constructed plumb to within 10mm over 4000mm and joints of block and brickwork should not be racked, but left flush-struck. Only suitable trained and approved applicators are permitted to apply the Impact squash wall coating system. Approved applicators will precisely follow the mixing and application procedures provided by the manufacturer.

PRODUCT DESCRIPTION

1. Impact Primer: A single component acrylic coating applied directly to the prepared substrate either by brush, roller or spray. To seal an otherwise porous surface and to provide a prime coat for the following procedure.
2. Impact Base Coat: Comprising two components, Impact Powder and Impact Liquid to be mixed at the ratio of 5 to 1 by weight i.e. 30kg powder to 6 litres of liquid. To a suitable size container first pour in liquid agitate slowly (avoid frothing) and gradually introduce powder. Continue mixing to achieve a consistent trowelable blend. Can be applied in a simple application up to 10mm thick or alternatively in hot climates it is preferable to apply two applications.
3. Impact Top Coat: A graded variation of Impact Base Coat.
4. Impact Finish Coat: A single component water based, polyurethane/acrylic coating applied direct from the container either by brush, roller or spray.

APPLICATION

1. Primer - Sealer - Apply one coat of Impact Primer @ 5 to 6m2 per litre.
2. Base Coat - Apply a scratch coat of Base Coat blend to level out uneven baseworks @ approx. 2 to 3mm thick. - Apply render finish of Base Coat @ approx. 6 to 7mm thick.
   Alternative Method (Hot Climates)
   - Apply first layer of Base Coat blend @ approx. 4 to 5mm thick.
   - Apply second layer of Base Coat blend @ approx. 4 to 5mm thick.
3. Top Coat - Apply one layer of Top Coat blend @ approx. 2 to 3mm thick.
4. Finish Coat - Apply two coats of "Impact Finish Coat" @ 10m2 per litre per coat.

COVERAGE

The playing area of squash court walls total approximately 110m2 (glass back courts = 95m2). Allowing for waste and a degree of surface imperfection the quantities used on average are:

SUBSTRATES

Blockwork, brickwork and concrete are suitable materials for the construction of playwalls. Blocks should be dense aggregate, Class A with a minimum compressive strength of 7N/mm2 and well cured. Bricks should be preferably plain to ensure minimum shrinkage. Sand-lime and other "commons" may be used. It is essential that all backgrounds be as dry as possible and free from soluble salts. Cement should be G.P. Portland grade. Sand should be sharp, clean river or pit sand washed to ensure free of salts and other contaminants.

PRE-INSTALLATION CHECKLIST

1. The court walls must be plumb, true and free from surface irregularities.
2. The surface must be clean, dry and free from all foreign matter including grease, oil, mould and dirt.
3. Suitable building facilities must be available including sufficient lighting, power, clean water and waste disposal facilities.
4. Door frames should be fixed 6mm from the face of the backwall to also act as a plaster stop. Where glass backwalls are specified the fixing jam should protrude 6mm from the side walls and also act as a plaster stop.
5. The wooden court flooring should not be installed until after the application of Impact.
6. Suitable building equipment should be available including festo mixer, trowels, screeds etc and mobile scaffolding.
