Centrecoat Armourcoat WB 2-200

Centrecoat Armourcoat WB 2-200 is a two part virtually solvent free epoxy resin coating offering excellent abrasion and chemical resistance. Provides a tough, hard wearing coating for light & medium duty traffic giving high performance at an economical cost.

Best Uses

Centrecoat Armourcoat WB 2-200 is formulated for use on light and medium duty flooring areas requiring an easy to clean, tough and durable coating with excellent chemical resistance. This 2 part floor coating is ideal for flooring in areas such as factories, warehouses, workshops, showrooms, packing and storage areas.

• Protects concrete from oil and chemical spillages
• Medium build
• Excellent wear resistance
• Virtually solvent free
• Gloss, easy to clean finish
• Low viscosity - easy to apply
• Non-dusting

BS 8204 Part 6 Synthetic Resin Flooring Type Categorisation

LD – light foot traffic, occasional rubber tyre vehicles, MD – regular foot traffic, frequent fork lift truck traffic, occasional hard plastic-wheeled trolleys, HD – constant fork lift truck traffic, hard plastic wheeled trolleys, some impact, VHD – severe heavily loaded traffic and impact

Application

Two coats are normally sufficient but on very porous substrates, an initial coat of Centrecoat Armourcoat 3-350 Primer may be required.

Concrete

Concrete substrates must be a minimum of 28 days old, dry, clean and free of surface laitance and contaminants such as dirt, oil, grease, poorly bonded coatings and surface treatments. 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 planing for these systems. Concrete must include a functional damp proof membrane.

Oil and Grease

For large areas of contamination, use hot compressed air treatment. Small, isolated contamination should be removed using an appropriate degreaser, rinsed thoroughly and allowed completely to dry. A coat of Armourcoat Oil Tolerant Primer should be applied (see separate data sheet).

Mixing

Materials should be stored at 15°C - 25°C for a minimum of 8hrs prior to use. Premix the coloured resin component before use. Add the hardener component to the coloured resin component and mix using a low speed electric mixer (200-500 rpm) for at least 3 minutes until homogeneous. Use a spatula to scrape the sides & bottom of the mixing vessel several times as unmixed material will result in uncured patches in the final finish. Mixed material must be used immediately.

Application

Best results are obtained in warm conditions (minimum 15°C). Apply with a medium pile simulated sheepskin roller working well into the surface taking care not to exceed the coverage rate. Edges & difficult to reach areas may be applied thinly by brush.An anti-slip finish may be achieved by fully broadcasting the first coat with 0.3 - 0.6mm kiln dried silica sand at 2 - 4 Kg/m2. Allow the first coat to fully cure (24hr 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. Coverage rate will depend on surface profile but will be greater than the first coat.Slip Resistance of System Detailed Above BS 7976 75 (Dry), 65 (Wet) The typical physical properties given above are derived from testing in a controlled laboratory environment. Results derived from testing field-applied samples may vary dependent upon site conditions. The slip resistance figures given above are affected by application techniques & prevailing site conditions. Slip resistance can reduce over time due to poor maintenance, general wear or surface contaminants. Good house keeping practices should be observed.
