Application works shall be carried out at ambient air and substrate temperatures from +5 °C to +35 °C.
It is recommended to prime the surface with SPEKTRON EPS-120 primer prior to application, using a brush or roller, at a consumption rate of 0.200–0.400 kg/m². The primer consumption depends on the quality and absorbency of the concrete substrate. The primer shall be allowed to fully cure and dry before application of the waterproofing compound.
The PUH-1K compound shall be applied in two cross-coats using a brush or roller. The second coat shall be applied after the first coat has dried (fully cured), but not earlier than 1 hour. Before applying the waterproofing layer, wait at least 4 hours and no more than 24 hours.
