Temperature resistance
| Short-term, maximum 7 days | +60 °C |
IMPORTANT
No simultaneous mechanical and chemical strain
While the product is exposed to temperatures up to +60 °C, do not also subject it to chemical and/or mechanical strain, as it may cause damage to the product.
Application
Mixing ratio
| Part A : Part B | 75 : 25 (by weight) |
Product temperature
| Minimum | +10 °C |
| Maximum | +30 °C |
Ambient air temperature
| Minimum | +10 °C |
| Maximum | +30 °C |
Relative air humidity
80 % r.h. max
Dew point
Beware of condensation. The substrate and uncured applied floor material must be at least +3 °C above dew point to reduce the risk of condensation or blooming on the surface of the applied product. Low temperatures and high humidity conditions increase the probability of blooming.
Substrate temperature
| Minimum | +10 °C |
| Maximum | +30 °C |
Substrate moisture content
< 4 % part by weight
Pot Life
| +10 °C | ~60 minutes |
| +20 °C | ~30 minutes |
| +30 °C | ~20 minutes |
Waiting time to overcoating
Before overcoating the product, allow:
| Substrate temperature | Minimum | Maximum |
| +10 °C | ~45 hours | ~4 days |
| +20 °C | ~36 hours | ~3 days |
| +30 °C | ~24 hours | ~18 hours |
Note: 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 | ~3 days | ~5 days | ~10 days |
| +20 °C | ~48 hours | ~3 days | ~7 days |
| +30 °C | ~24 hours | ~48 hours | ~5 days |

| Applied as a seal coat on Sikafloor®broadcast substrates | ~0,6–0,9 kg/m2 |
Note: These figures are theoretical and do not allow for any additional material due to surface porosity, surface profile, variations in level, wastage or any other variations. Apply product to a test area to calculate the exact consumption for the specific substrate conditions and proposed application equipment.
EQUIPMENT
MIXING EQUIPMENT
- Electric single paddle mixer (300 to 400 rpm)
- Electric double paddle mixer (> 700 W, 300 to 400 rpm)
- Forced action mixer
MIXING
MIXING PROCEDURE
- Mix Part A (resin) for ~10 seconds with a single paddle mixer (300–400 rpm).
- Add Part B (hardener) to Part A.
- Switch to an electric double paddle mixer (300–400rpm, > 700 W).
- While mixing Parts A + B, gradually add the required filler or aggregates.
- Mix for a further 2 minutes until a uniform mix is achieved.
- To ensure thorough mixing, pour materials into another container and mix again to achieve a smooth and uniform mix.
- During the final mixing stage, scrape down the sides and bottom of the mixing container with a flat or straight edge trowel at least once to ensure complete mixing.
APPLICATION
IMPORTANT
Protect from moisture
After application, protect the Product from damp, condensation and direct water contact for at least 24 hours.
IMPORTANT
Temporary heating
If temporary heating is required, do not use gas, oil, paraffin or other fossil fuel heaters. These produce largequantities of both carbon dioxide and water vapour, which may adversely affect the finish. For heating, use only electric powered warm air blower systems.
BINDER
- Pour the Product onto the surface.
- Apply the Product evenly over the surface with atrowel.
SEAL COAT
- Pour the mixed Product onto the surface. Note: The consumption is specified in Application Information.
- Apply the Product evenly over the surface with a squeegee.
- Back roll the surface in two directions at right angles with a short pile roller. Note: A seamless finish can be achieved if a "wet"edge is maintained during application.
CLEANING OF EQUIPMENT
Clean all tools and application equipment with Sika® Thinner C immediately after use. Hardened material can only be removed mechanically
