Exposure to Direct Sunlight

Note: When the product is exposed to direct sunlight, there may be some discolouration and colour variation. This has no influence on the function and performance of the coating.

Technical Information

Tensile adhesion strength

> 1.5 N/mm² (failure in concrete)

(EN 1542)

Service Temperature

IMPORTANT

Simultaneous Mechanical and Chemical Strain

While the Product is exposed to temperatures up to +60 °C, simultaneous mechanical or chemical strain may cause damage to the Product.

Do not expose the Product to chemical or mechanical strain at elevated temperatures.

Application Information

Mixing Ratio

Part A : Part B (by weight)

85 : 15

Sikafloor-54 Booster

Note: Add between 2 % and 4 % of Sikafloor-54 Booster, by weight of the mixed resin, to the Product to decrease the waiting times.

Product Temperature

Minimum	+8 °C
Maximum	+23 °C

Ambient Air Temperature

Minimum	+8 °C
Maximum	+30 °C

Relative Air Humidity

Maximum	80 % r.h.
Minimum	20 % r.h.

Dew Point

Beware of condensation. The substrate and uncured applied product 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	+8 °C
Maximum	+23 °C

Substrate Moisture Content

Refer to the Product Data Sheets of the individual primer
