Centrecoat Armourcoat PUFlex 3-500

Centrecoat Armourcoat PUFlex 3-500 is a two part flexible polyurethane floor coating with a gloss finish, suitable for medium duty traffic with occasional fork lift use.

Best Uses

Centrecoat Armourcoat PUFlex 3-500 is suitable for the protection of concrete floors subject to medium duty traffic (regular foot traffic, occasional fork lift truck traffic, occasional hard plastic-wheeled trolleys).

• Easy to apply
• Low odour
• Hard wearing, tough and resilient
• Seamless
• Hygienic / easy to clean and maintain

This polyurethane floor coating is suitable for application onto concrete, polymer modified cementitious screeds, steel, timber and some asphaltic surfaces. Typical environments include hospital flooring, pharmaceutical manufacturing, cafeterias and canteens, offices, school, hotels, retail outlets, leisure facilities, health clubs, sports arenas, multi-purpose halls, exhibition areas and museums.

Application

Inadequate preparation will lead to loss of adhesion and failure. In coating systems, there is a tendency for the finish to minor imperfections in the substrate. For concrete substrates, grinding or light vacuum contained shot-blasting is therefore preferred over planing for these systems.

A primer is not usually required. On extremely porous substrates, apply Centrecoat Armourcoat Multi-Use Primer. See separate data sheet. If, when cured, there are dry patches, a further primer coat is may be required. Allow to cure between coats. If the primer or previous coats have been left to cure for >48 hours, then the primer surface should be mechanically abraded and the area re-primed. Failure to do so may result in loss of adhesion.

Prior to mixing, the temperature of the two components must be between 15 and 25°C. Add the hardener component to the coloured resin component and mix using a low speed electric mixer (300 - 400 rpm) for at least 3 minutes until homogeneous. Keep the mixing paddle fully submerged to avoid the entrapment of air, and scrape the sides and bottom of the vessel several times. Decant the mixed material to a second mixing vessel and mix as above for a further minute.

Distribute the mixture immediately onto the surface using a medium pile roller and apply evenly. Plan the work area to ensure a constant wet edge and work within the working time of the material.

Centrecoat Armourcoat PUFlex 3-500 reacts with water, causing foaming. During application, take care that no sweat drops fall into the uncured material. Wear head and wrist bands during application.
