Sports Floor Coating Selection: Acrylic and Cementitious Systems for Singapore Courts
Comparison of water-based acrylic sports floor coatings (Berger) and cementitious sports court systems (Weberfloor) for outdoor and indoor courts in Singapore, with surface preparation notes.
Choosing the right sports floor coating is one of the most consequential decisions on a court marking project. The coating determines how the surface looks, how slip-resistant it feels under foot, how the line paint adheres and how long the markings remain readable. This article compares two systems whose datasheets we work with on Singapore court projects: a water-based acrylic sports floor coating (Berger Sports Floor Coating) and a cementitious sports court system (Weberfloor sports court system).
Water-based acrylic sports floor coating (Berger)
From the Berger Product Specifications — Sports Floor Coating (Revision 3, April 2014):
- Product type: single-pack, reinforced waterbased acrylic, with a special non-skid aggregate.
- Suitable for: internal and external sports floors, including tennis and basketball courts.
- Volume solids: 40%.
- Dry film thickness: 25 μm per coat; wet film thickness 63 μm per coat.
- Number of coats: 2.
- Theoretical coverage: 16 m² per litre per coat at 25 μm DFT.
- Finish: matt; colours on request.
- Standard packing: 5 litres.
- Application: roller recommended; brush for small or inaccessible areas. Maximum thinning 10% with water.
- Drying: at 25 °C, touch dry in 1 hour, hard dry in 4 hours, minimum overcoat 8 hours; intervals shorten at higher temperatures.
- Surface prep highlights: new concrete cured for at least 21 days; moisture content checked and confirmed below 6% with a reliable meter; algae or grease cleaned and rinsed; sealer applied prior to topcoat; pressure-washing of any old coatings before overcoating.
This system suits outdoor concrete or asphalt courts in Singapore where slip resistance, water resistance and a colour finish are the main needs. The non-skid aggregate provides the playing-surface texture, and lines are then painted on top.
Cementitious sports court system (Weberfloor)
From the uploaded technical data sheet TDS — Weberfloor sports court system (Weber/Saint-Gobain product literature), the system is a cementitious sports court base for new external courts where a durable, level base layer is required before the coloured topcoats and line painting are applied. Cementitious systems are typically chosen when:
- The existing substrate needs significant levelling and a stronger base layer than a simple acrylic primer can give.
- The court is being built up from a new slab and the specifier prefers a cement-based intermediate layer for dimensional stability.
- The court must take heavier dynamic loads than a thin acrylic system would normally absorb on its own.
The Weberfloor system datasheet supplied to us is image-only on certain pages. For specific mixing ratios, thicknesses and compressive strength figures, refer to the manufacturer's current published TDS. We assess each project individually before specifying.
Selecting between acrylic and cementitious systems
| Factor | Acrylic (Berger) | Cementitious (Weberfloor) |
|---|---|---|
| Typical use | Repaint/recoat of existing courts; new courts on sound concrete | New courts needing a built-up base layer |
| Build-up | Sealer + 2 coats acrylic (thin film) | Cementitious base + acrylic topcoats |
| Slip resistance | From non-skid aggregate in coating | From topcoat applied over cementitious base |
| Substrate cure / drying | 21-day cure on new concrete; <6% moisture target | Manufacturer-specified cure of the cementitious layer first |
| Repaintability | Easy to overcoat after pressure washing | Easy to repaint top layer; base layer is long-term |
Implications for line marking
Whichever base system is chosen, the line paint must be compatible with the topcoat. We typically use an acrylic line paint over the Berger system and a matched line paint over Weber-based sports systems. Drying intervals, total coat thicknesses and recoat times are all set by the topcoat datasheet. We follow those drying times rather than rushing through the job.
For details on preparing the substrate before either system goes down, see our companion article on surface preparation for court marking.
