Joint Design
| Maximum gap width1: | 50 mm |
| Positive horizontal joint movement2: | +30 mm |
| Negative horizontal joint movement3: | -20 mm |
| Positive vertical joint movement4: | +15 mm |
| Negative vertical joint movement5: | -15 mm |
1Width of the gap in the concrete below Sika® FloorJoint PDRS during installation.
2Positive horizontal joint movement is the amount the gap can horizontally open, compared to its original width during installation of Sika® FloorJoint PDRS.
3Negative horizontal joint movement is the amount the gap can horizontally close, compared to its original width during installation of Sika® FloorJoint PDRS.
4Positive vertical joint movement is the amount the gap can vertically open, compared to its original width during installation of Sika® FloorJoint PDRS.
5Negative vertical joint movement is the amount the gap can vertically close, compared to its original width during installation of Sika® FloorJoint PDRS.
Note: To provide a waterproof joint, first, install Sikadur® Combiflex® SG System below the Sika® FloorJoint PB-30 PDRS.
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® Wear Layer on Sikadur®-30/-31 CF Normal + Sika®-FloorJoint PDRS allow:
| Substrate Temperature | Minimum | Maximum |
| +10 °C | 24 hours | 14 days |
| +20 °C | 12 hours | 10 days |
| +30 °C | 8 hours | 7 days |
Before grinding and applying Sikafloor®-359 N on Sikafloor®-375 allow:
| Substrate Temperature | Minimum | Maximum |
| +10 °C | 24 hours | 48 hours |
| +20 °C | 15 hours | 24 hours |
| +30 °C | 8 hours | 16 hours |
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 | 24 hours | 72 hours | 7 days |
| +20 °C | 12 hours | 30 hours | 5 days |
| +30 °C | 5 hours | 24 hours | 4 days |
Note: Times are approximate and will be affected by changing ambient conditions.
Consumption
| Coating | Product | Consumption |
| Adhesive | Sikadur®-31 CF Normal | ~ 3–5 kg/linear meter (dependingof the depth of the cut-out) |
| Waterprofing | Sikadur®-31 CF Normal + | Adhesive: ~ 1.2 kg/linear meter; Combiflex tape: 1 m/linear meter |
| Floor Panel | Sika® FloorJoint PDRS + Rubber Seal gummed up with | 1 panel = two pieces of polymer panels + rubber seal: 1.2 m. ~ 70 g/linear meter |
| Activator | Sika® Activator 205 is used to prime the panel and the back side of the rubber seal | ~ 5 g/linear meter |
These figures are theoretical and do not allow for any additional material due to surface porosity, surface profile, variations in level or wastage etc.
