Centrecoat Armourcoat 3-350

Centrecoat Armourcoat 3-350 is a 2 part, 100% solids epoxy floor coating offering excellent abrasion and chemical resistance. Provides a tough, hard wearing coating for medium duty traffic, giving high film build and wear resistance.

Best Uses

Centrecoat Armourcoat 3-350 is formulated for medium duty flooring areas requiring an easy to clean, tough and durable coating with excellent chemical resistance. Centrecoat Armourcoat 3-350 is ideal for warehouses, factories, workshops, showrooms, packing and storage areas. Suitable for application onto concrete and polymer modified cementitious screeds.

• Protects concrete from oil and chemical spillages
• High build with excellent wear resistance
• 100% solids
• Easy application - no need for solvent/thinners
• Gloss, easy to clean finish
• Non-dusting
• Slip-resistant options available
• Nonyl phenol free - reduced hazard

Centrecoat Armourcoat 3-350 can also be used as a seal coat for broadcast systems such as intermediate car park decks. Armourcoat 3-350 is suitable for regular foot traffic, light duty fork lift truck traffic and occasional hard plastic-wheeled trolleys.

Application

Concrete substrates must have a minimum compressive strength of 25 N/mm2 and a minimum pull-off strength of 1.5 N/mm2 and be dry (≤ 4% by weight), clean and free of surface laitance and contaminants such as dirt, dust, loose material, oil, grease, poorly bonded coatings and surface treatments. Concrete must include a functional damp-proof membrane and be free of rising moisture.

Inadequate preparation will lead to loss of adhesion and failure. In coatings, there is a tendency for the finish to mirror imperfections in the substrate. Grinding, or light vacuum-contained shot-blasting, is therefore preferred over planning for these systems. Weak concrete must be removed and voids filled with a suitable repair material. High spots must be removed, e.g. by grinding. Excessively porous concrete should be primed using Armourcoat 3-350 Primer. If in doubt, apply a test area first.

Materials should be stored at 15°C to 25°C for a minimum of 8 hours prior to use. Mechanically premix the coloured resin component before use. Add the hardener component to the coloured resin component and mix using a low speed electric mixer (300 - 500 rpm) for at least 3 minutes until homogeneous. Use a spatula to scrape the sides and bottom of the mixing vessel several times during mixing, as unmixed material will result in uncured patches in the final finish. Pouring the mixed material into a second mixing container and mixing again will greatly reduce the possibility of soft spots. Do not add solvent/thinners to the product.

Best results are obtained in warm conditions (minimum 15°C). Apply with a short pile roller, working well into the surface, taking care not to exceed the coverage rate. Edges and difficult to reach areas may be applied thinly by brush. The second coat should be applied at right angles to the first. An anti-slip finish may be achieved by fully sprinkling the first coat with kiln dried silica sand at 3 - 4 kg/m2. Allow the first coat to fully cure (24 hours at 15°C or longer in colder temperatures) then remove all excess sand with a stiff broom and vacuum. Apply a second coat to encapsulate the grains, using a squeegee, followed by back-rolling with a short pile roller.
