Wecryl 420

Roller-applied Coating

Brief Description

Wecryl 420 is designed as a versatile PMMA coating for application to bituminous substrates and as part of the Wecryl systems. Offering excellent abrasion‐resistance and non‐skid properties, Wecryl 420 was developed specifically as heavy‐duty surfacing and can be applied to asphalt substrates without a primer. The product is used as a prime surfacer, a topping layer and final course on external surfaces that are subject to pedestrian and vehicular traffic, such as roads and plazas; urthermore it is used for coloured road markings as well as for coating mastic flooring incorporating toppings. The surface can be of any colour and this coating can even be used to create patterns or car park markings and traffic guidance.
