Coatings available include:
- Water based acrylic colour coatings
- Polyurethane colour coatings
- Proflex court
- Proflex cushion acrylic
It is important to remember that the painted coating forms the playing surface. If it is applied incorrectly the performance and durability of the court can suffer.
The use of binders has become popular in recent years. They are clear coatings that are applied to new or old macadam surfaces to provide enhanced strength to the playing surface. They also aid the adhesion of the paint coating to the macadam surface, acting as a form of tack coat. Binders are available in either water or solvent-based acrylic or polyurethane formulations and are spray applied.
- close to trees – the binders will help resist the effects of tree sap and bird droppings on the court surface;
- subjected to high levels of use or where non-tennis shoes are likely to be worn;
- subjected to prolonged periods of shade leading to damp areas;
- used by wheelchair players.
- On older macadam surfaces, where the original bitumen binder incorporated in the macadam mix has aged and noticeably started to weaken, the application of a binder coat may prolong the life of the macadam surface.
- On very weak macadam, however, the quantity of binder required to hold the surface together may be such that it seals or partly seals the surface resulting in a significant loss in porosity. As a rule of thumb, if an old court starts to break-up during power washing the level of deterioration is likely to be so great that an application of binder will not be effective, and resurfacing is therefore required.
- As binders do not have any form of texturing agent in their formulation the resulting film coating will be slippery when wet or damp. If a binder coat is applied a court must also be colour-coated.
- Applying a binder will not improve the texture of the macadam surface.
- Heavily pitted macadam will still be heavily pitted after a binder coat is applied.
