Sikafloor® MultiFlex PB-54 UV
Broadcast, high performance polyurethane floor covering with UV stable top sealer over elastic membrane
Sikafloor® MultiFlex PB-54 UV is a dynamic crack-bridging, waterproofing and slip resistant polyurethane flooring system and is part of the Sikafloor® Multiflex flooring range.
Sikafloor® MultiFlex PB-54 UV is especially designed for use in car park UV exposed decks where seamless, weather, UV resistant, colour stable and hardwearing floors are required.
Sikafloor® MultiFlex PB-54 UV consists of a high elastic spray applied, very fast curing polyurethane/polyurea hybrid membrane, a crack bridging polyurethane base coat over which a UV stable flexible top coat is applied, in order to provide a well-defined surface profile.

Application
Material temperature
+10 °C min. / +30 °C max. For the spray applied membrane refer to the individual Product Data Sheet.
Ambient air temperature
+10 °C min. / +30 °C max. For the spray applied membrane refer to the individual Product Data Sheet.
Relative air humidity
80 % max.
Dew point
Beware of condensation!
The substrate and uncured floor must be at least 3 °C above dew point to reduce the risk of condensation or other disturbance of the surface on the floor finish
Substrate temperature
+10 °C min. / +30 °C max.
Substrate moisture content
Sikafloor® MultiFlex PB-54 UV can be installed on substrates with moisture content of max. 4 % (checked by Tramex). The substrate needs to be visibly dry and have an adequate pull-off strength min 1.5 N/mm2. Check for rising moisture.
