Grow Squash

Squash was invented in Harrow school around 1830, when the pupils discovered that a punctured Rackets ball, which “squashed” on impact with the wall, produced a game with a greater variety of shots and required much more effort on the part of the players, who could not simply wait for the ball to bounce back to them as with Rackets. The variant proved popular and in 1864 the first four Squash courts were constructed at the school and Squash was officially founded as a sport in its own right.

Squash is played in more than 185 countries, on nearly 50,000 courts, and the WSF now has 147 Squash playing National Associations in membership. It is the sole International Federation for the sport, as recognised by the International Olympic Committee (IOC), and maintains responsibility for the Rules of the Game, Court and Equipment Specifications, Refereeing and Coaching. The WSF maintains a World Calendar of events, organises and promotes World Championships for Men, Women, Junior Men, Junior Women and Masters age groups in both singles and doubles Squash; and leads its Member Nations in programmes for the development of the sport. Squash has been played for over 140 years, grown sensationally in the last forty and is now poised to become one of the largest and best loved of all sports.

Squash is played in an enclosed court which is a rectangular box with four vertical walls of varying height

Painting Squash Court Wall

For a good job you need the proper paint contact  Pat McDonnell Paints for advice. Go onto their website HERE  for your local store. They will call out to your courts to offer free advice. Squash Court Paint should be at a cost of no more than €75 per 5 litre tin plus VAT. Two tins will do a single coat but you should give it a second coat for a proper job. Maybe you can do 2 courts with 6 or 7 tins rather than 8 tins. You can apply with brush or roller and if some of your members are ‘handy’ and cover the floor properly you should be able to do the painting yourself. Of course a painter will do a better job.

Floor Sanding

Most floors will take a sanding a few times before it becomes problematic to do so. However, you should use a professional (carpenter) who will use a belt sander lengthways and not across the grain. The carpenter should be asked to make good any ‘dodgy’ floorboards as part of the job. You should be able to get this done for anything around €250 / €300 per court . It takes a day to do a court . You will need a lot of voluntary work from your members to vacuum the courts and surrounding area once the sanding is done. Remember to wipe down the walls and light fittings before you start vacuuming! It will have to be done many times before using the courts again as it takes days for the dust to settle. You should then clean off the courts with something like white spirits.You are better off not to apply any floor varnish when the sanding is done but club members have to be told to use court shoes in future and not simply non-marking shoes. The difference is that you want them going on court only with shoes used exclusively for squash! If you are lax in this area it will result in marked courts and a recurrence of the problem.The court markings should be renewed using some strong and quick drying paint.

New Floor

If your floor is very old and needs to be replaced we recommend a specialist SylvaSquash Beech floor system and New Era Cradle System supplied by Junkers, a Danish company who specialist in floors. Contact: Junkers Ltd., email:

Cleaning the squash courts: The first point to stress is that brushing squash courts is not a good idea. It causes the dust and dirt to be moved about thereby smearing the surface and dust will lodge between the floorboards only to rise again once the players run about the court. It also causes a greasy film to be formed on the surface and, over time, the courts become slippery.Ideally the courts should be vacuumed a couple of times per week and a damp cloth wrapped around the brush head should be applied to the courts maybe weekly to remove any dirt.

Squash Shoes: Players should be required to use non-marking squash shoes that are not worn anywhere else. (Merely requesting non-marking shoes will not keep your courts clean if the players use them for other sports or indeed use them outside the squash courts. The shoes become dirty and then mark the courts)

Other information: England Squash do a very comprehensive manual for care of squash courts and it costs about £40. They also have a number of technical information sheets on the site
