  Acrylic

A non-turf, artificial, surface used for some tennis courts; it allows for play to take place 12-months of a year. The court is constructed with a macadam base and the surface is made of numerous layers of coloured acrylic material (Acrylic Colour Coat), several millimetres in thickness, and which helps to seal the surface. Acrylic material can be either sprayed onto a surface creating a porous layer, or liquid applied with a squeegee creating an impervious surface.

  Adhesive

A glue used for sticking synthetic carpets together. Underneath the join on a carpet will typically be a thin strip of synthetic material (often called a ‘Seaming Tape’) to which the adhesive is placed, and the carpet firmed down.

  Air Jetting

A major and infrequent renovation activity carried out on artificial carpets to eject sand, or rubber crumb, through the use of compressed air.

  All Weather Surface

There is nothing of the sort. This is a bit of a misnomer because there is no surface which is all weather. A frozen or snow-covered surface would, or should, not be played on, particularly from a health and safety perspective. A surface which is exposed to extreme heat temperatures would not also be suitable for playing on due for example to potential heat burn from the surface or heat exhaustion of players. This is a term which is often, incorrectly used to describe a range of artificial non-natural turf surfaces. More correctly they should be called ‘extended weather’, ‘most weathers’, or similar, surfaces.

  Asphalt

A black petroleum based solid mixture composed of bitumen, sand and crushed rock. It is typically used for general play areas and some non-turf tennis courts. It is also commonly referred to as Macadam.
