Sika® FloorJoint PS-30 S
CARBON FIBRE PREFABRICATED FLOOR JOINT SYSTEM
Sika® FloorJoint PS-30 S is a carbon fibre reinforced polymer (CFRP) composite, prefabricated, floor joint system with high mechanical resistance for normal up to medium wear loading conditions. Its sinusoidal surface tooth profile allows for an improved load distribution and results in minimum vibrations under direct car and forklift traffic. Gap widths: 0 – 30 mm.
- Grindable profile for level integration into the floor surface
- Reduced vibrations under direct car and forklift traffic
- Thermal expansion coefficient similar to resin based floors
- Easy to install
- Easy to repair
- Short down time - Trafficable after only 24 hours
- Waterproof system design possible
- High chemical resistance
- Non corroding
- High mechanical resistance

System Structure
Sika® FloorJoint PS-30 S:
| 1. Backing rod | Screed edge stripping. Height: 80 mm–100 mm, thickness 5 mm. |
| 2. Adhesive | Sikadur®-31 EF / Sikadur®-31+ Slow |
| 3. Floor joint panel | Sika® FloorJoint S |
| 4. Floor coating | e.g. Sikafloor®-264/-263 SL |
Composition
Floor joint panel: Carbon fibre reinforced polymer.
Shelf Life
Refer to individual Product Data Sheet.
Storage Conditions
Refer to individual Product Data Sheet.
Reaction to Fire

| 0 mm | +20 mm 4 | -0 mm |
| 5 mm | +17.5 mm 4 | -5 mm |
| 10 mm | +15 mm 4 | -5 mm |
| 15mm | +12.5mm 4 | -5 mm |

| 25 mm | +7.5 mm | -5 mm |
| 30 mm | +5 mm | -5 mm |
- Width of the gap in the concrete below Sika® floor Joint panel during installation.
- Positive joint movement is the amount the gap can open, compared to the original width during installation of Sika® floor Joint panel. Do not exceed the maximum positive joint movement capacity, otherwise the teeth of the Sika® floor Joint panel become unsupported and may be damaged.
- Negative joint movement is the amount the gap can close, compared to the original width during installation of the Sika® floor Joint panel.
- The sealant may break at a positive joint movement of ~10 – 15 mm, however this does not affect the technical performance of Sika® FloorJoint PS-30 S. The purpose of the joint sealant is the reduction of dirt pick-up in the joint, not to provide water tightness. Install Sikadur® Combiflex® SG System below Sika® FloorJoint PS-30 S if a waterproof joint design is required.
Application
Ambient Air Temperature
The ideal installation temperature is approx. +15 °C min. / +25 °C max. Refer to the product data sheet of the individual product for specific information.
Relative Air Humidity
80 % r.h. max.
Dew Point
Beware of condensation!
The substrate and uncured floor must be at least 3 °C above dew point to reduce the risk of condensation or blooming on the floor finish.
Substrate Temperature
The ideal installation temperature is approx. +15 °C min. / +25 °C max. Refer to the product data sheet of the individual product for specific information.
Substrate Moisture Content
<4 % pbw moisture content.
Test method: Sika Tramex Meter, CM-measurement or Oven-Dry-Method. No rising moisture according to ASTM (Polyethylene-sheet).
Waiting Time / Overcoating
Before grinding and applying Sikafloor®-Top Coat on Sikadur® adhesive and Sika®-FloorJoint S allow:
| Substrate Temperature | Minimum | Maximm |
| +10 °C | 24 hours | 14 days |
| +20 °C | 12 hours | 10 days |
| +30 °C | 8 hours | 7 days |
Times are approximate and will be affected by changing ambient conditions particularly temperature and relative humidity.
Applied Product Ready for Use
| Temperature | Foot Traffic | Light Traffic | Full Cure |
| +10 °C | 72 hours | 6 days | 10 days |
| +20 °C | 24 hours | 4 days | 7 days |
| +30 °C | 18 hours | 2 days | 5 days |
Times are approximate and will be affected by changing ambient conditions particularly temperature and relative humidity.
Consumption
Sika® FloorJoint PS-30 S System:
| Component | Product | Consumption |
| Adhesive | Sikadur®-31 EF / Sikadur®-31+ Slow | ~3–5 kg / linear metre (depending on the depth of the cut-out) |
| Floor joint panel | Sika® FloorJoint S | 1 piece for 1.2 linear metre |
| Top coat | Sikafloor®-Top Coat | Refer to relevant system data sheet |
These figures are theoretical and do not allow for any additional material due to surface porosity, surface profile, variations in level or wastage etc.
