Product Description

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 as 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.

BS 8204 Part 6 Synthetic Resin Flooring Type Categorisation

FeRFA No Type Description Duty Typical Thickness
1 Floor Seal Applied in 2 or more coats. Generally solvent or water borne LD > 150μm
2 Floor Coating Applied in 2 or more coats. Generally solvent free LD / MD 150 - 300μm
3 High build floor coating Applied in 2 or more coats. Generally solvent free. MD 300 - 1000μm
4 Multi-layer flooring Aggregate dressed systems based on multiple layers of floor coatings or flow-applied flooring, often described as sandwich systems MD / HD > 2mm
5 Flow-applied flooring Often referred to as ‘self-smoothing’ or ‘self-levelling’ flooring and having a smooth surface MD / HD 2 - 3mm
6 Resin screed flooring Trowel-finished, heavily filled systems, generally incorporating a surface seal coat to minimise porosity MD / HD > 4mm
7 Heavy duty flowable flooring Having a smooth surface HD / VHD 4 - 6mm
8 Heavy duty resin flooring Trowel-finished, aggregate filled systems effectively impervious throughout their thickness. VHD > 6mm

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


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.

It is your responsibility to read and understand all aspects of the data sheets before you place an order and prior to application. Please pay special attention to the preparation, mixing and application temperatures of the product, cleaning of substrate and environmental factors such as temperature, rain etc. Quoted coverage rates are based on the manufacturers theoretical rates and may vary depending upon substrates absorption, texture and application. We always recommend a test is carried out to ensure suitability.
