Description of the product
USE:
Primer/Finish rust preventive coating for metal sheets and claddings.
FEATURES:
Single component coating for the protection of metallic objects. RD-Metal Unicoat is an excellent choice for the renovation of metallic objects located in low to moderate corrosive environments and can be applied directly on steel and weathered galvanized steel without having to blast the surface.
RD-Metal Unicoat is water-based, easy to handle, safe and has no fire risks.
It is a fast-drying coating system that greatly reduces downtime during installation.
Virtually odour free, it does not affect neighbouring occupants and can therefore be used in occupied buildings.
RD-Metal Unicoat is UV resistant, has a good resistance against weathering and can therefore be applied as primer and/or as finish. When applied by airless, RD-Metal Unicoat easily covers large flat surfaces with no overlaps and will protect the coated objects neat and tidy for numerous years. It is therefore is an excellent, fast and easy renovation system for claddings and coated metal sheets.
RD-Metal Unicoat is part of the SCS – Single Coating System - product group.

(*) New or recent side wall claddings : it is imperative to perform an adhesion test beforehand. New sidings are usually covered with special coatings that limit dirt pick up. These kind of finishes sometimes prevent the good adhesion of a paint system applied on top. The effect of these finishes fades over time, making it easier to apply paints on sidings that are more than 10 years old. However, even on older sidings, it is still advisable to do an adhesion test beforehand.
(**) In case of corroded surfaces or when the objects are located in a more corrosive atmosphere (C4 or C5), it is advised to use RD-Elastometal as a prime coat.
Aesthetical fresh-up:
A single coat is possible on previously painted surfaces in need of an aesthetic refreshment.
Risks of chemical spills, graffitis or nearby aggressive exhaust fumes/pollution:
The system can be top coated by one or two coats of RD-Hydrograff HP Clear High Gloss.
Indicated consumption is theoretical and does not consider potential losses during application. It can also be influenced by the porosity of the substrate.
Application instructions
