Two component, fast-reactive primer for asphalt surfaces Sikalastic® Rapid Asphalt Primer is a fast reactive primer used as a barrier on asphalt substrates in preparation for the later application of Sikalastic® Rapid waterproofing or surfacing products. - Very good adhesion to asphalt substrates
- Fast curing
- Can be applied at sub-zero temperatures
- Hydrolysis and alkali resistant
- Easy and fast application
- Solvent-free
|
Usage - Used for the pre-treatment (primer and barrier coat) of asphalt substrates (eg mastic asphalt)
- For new construction and refurbishment projects
Advantages - Very good adhesion to asphalt substrates
- Fast curing
- Can be applied at sub-zero temperatures
- Hydrolysis and alkali resistant
- Easy and fast application
- Solvent-free

Application Information Ambient Air Temperature -5 °C min. / +35 °C max Relative Air Humidity The relative humidity must be ≤90% Dew Point Beware of condensation. Surface temperature during application and cure must be a minimum of 3°C above dew point. The substrate temperature must not be less than +3°C if a topping is applied to the surface. Reaction problems can occur at lower temperatures. Substrate Temperature -5 °C min. / +50 °C max Substrate Moisture Content The surface to be coated must be dry and ice-free
The surface must be protected from moisture until the coating has hardened Pot Life The material in opened containers should be applied immediately. At 20°C, 2% catalyst the pot life is approximately 15 minutes Curing Time | Temperature | Catalyst | Rain Resistant | Can be trafficked/overcoated | Full cure | | 20°C | 3% | 30 minutes | 45 minutes | 3 hours |
Note: Times are approximate and will be affected by changing ambient conditions. Higher temperatures or greater proportions of Sikalastic® Rapid Catalyst will reduce reaction times, while lower temperatures and smaller proportions of Catalyst will increase reaction times. The following table indicates the recommended amount of Sikalastic® Rapid Catalyst required to adjust the curing reaction to the temperature. Substrate temperature in °C; required amounts of Sikalastic® Rapid Catalyst in % w/w (guide) | -10 | -5 | +3 | 5 | 10 | | - | 6% | 6% | 6% | 4% |
| 15 | 20 | 25 | 30 | 35 | | 2% | 2% | 2% | 2% | 2% |
Return-to-service times are provided as a guide only and may vary as a result of conditions. Newly installed balconies should be protected from exposure to heavy traffic by overlaying with an appropriate protective covering. This is particularly critical where early access is needed by other construction related traffic. Sika Liquid Plastics will not be held responsible for damage to balcony surfaces that results from failures to adequately protect newly laid areas.
