Substrate Pre-Treatment
Normal intended use of the floor
The one part acrylic primer Sikafloor®-01 Primer is recommended for a pore free surface with very good surface adhesion. Refer to the relevant PDS for the recommended application details etc.
High loads intended use of the floor
Priming with epoxy resins such as Sikafloor® -155WN, Sikafloor® -150 or Sikafloor® -151 fully broadcast with quartz sand 0.3–0.8 mm.
Pot Life
Temperature and Relative Air Humidity | Time |
+23 °C / 50% | ~ 25 minutes |
The temperature will affect the pot life.
Application at temperatures above +23 °C will reduce the pot life and the working time. Temperatures below +23 °C will increase the pot life and extend the working time.
Waiting Time / Overcoating
| Covering | Layer Thickness | Waiting Time |
| Impermeable or moisture sensitive coatings | ≤ 15 mm | 24 hours1 |
| Impermeable or moisture sensitive coatings | ≤ 30 mm | 48 hours1 |
| Cermanic covering | ≤ 30 mm | 24 hours |
- Times are approximate and at +23 °C and 50% r.h. and thus will be affected by changing substrate and ambient conditions, particularly the temperature and relative humidity.
When overcoating Sikafloor® Level-30 always ensure the moisture content has achieved the required value for the coating product, as the waiting time will vary with the application thickness and ambient humidity. (Refer to the coating product data sheet)
Applied Product Ready for Use
At +20 °C and 50% r.h.
Foot traffic | ~ 3 hours |
Lightly serviceable | ~ 24 hours |

MIXING
By Hand
For 25 kg Sikafloor® Level-30 is required 5 to 5.25 l water. When mixing manually add the dry powder (25 kg) into a container with the clean water.
Mix thoroughly for a minimum of 3 minutes, by use of an electric stirrer, recommended is the use of a double disc stirring paddle or a spiral mix paddle (< 500 rpm).
maturing time: After mixing leave the material to stand in the container for ~ 2 minutes until the majority of air bubbles have dispersed.
Pumping
When using a mortar pump with appropriate equipment (Putzmeister MP 20/25, DuoMix 2000 or PFT G5 FE) set the machine in a way that a uniform mixture is achieved. The use of a remixer is recommended.
Control the water dosage to achieve the required flow, measuring the final average flow diameter on a flat, clean, dry flow table.
| Tool | Flow | Standard |
| Ø = 30 mm H = 50 mm | 130 mm ± 5 mm | EN 12706 |
| Ø 70 / 100 mm H = 60 mm | 355 mm ± 10 mm | ASTM C 230-90 EN1015-3 |
| Ø = 60 mm H = 120 mm | 290 mm ± 10 mm | Sika AT method |
APPLICATION
Pour the mixed material onto the primed surface and apply by trowel or pin screed rake to the required thickness. Roll thoroughly with a spiked roller in two directions to remove any entrapped air. Best application time would be during falling temperatures.
CLEANING OF TOOLS
Clean all tools and application equipment with water immediately after use. Hardened / cured material can only be removed mechanically.
