1. Dependant on environmental conditions. Values attained at 23 °C and 50% rel humidity. Times given are reduced with higher (and increased with lower) surrounding and work surface temperatures.

Application Conditions

Apply only when atmospheric and substrate temperatures are greater than 5 °C. The surface of the substrate should be clean and dry and must be 3 °C above the dew point. If the surface is below or at dew point temperature then moisture can form at the surface and affect coating adhesion and curing.

Application Method

Prime in one operation and distribute the primer with a perlon roller to avoid accumulation of material.

Once Sealoflex Prima TPO Primer is dry and tack-free, the Sealoflex Prima LWS waterproofing system can be applied after 15-30 minutes depending on atmospheric conditions. Ensure the Sealoflex Prima LWS waterproofing system is applied within 24 hours, otherwise separation effects can occur.

Personal Protective Equipment (PPE) should be worn.
