*PPG EP301 High Build Epoxy Floor Coating

Please note, this product has been discontinued. See Centrecoat Armourcoat 3-350 as a potential alternative.

PPG EP301 is a two-component solvent free epoxy resin floor coating offering excellent abrasion and chemical resistance. Provides a tough, hard wearing coating for medium duty traffic giving excellent wear resistance.

Best Uses

Suitable for use in medium duty areas requiring an easy to clean, tough and durable resin floor coating with good resistance to chemicals. Ideal for use in areas such as warehouses, factories, workshops, showrooms, packing and storage areas. PPG EP301 is suitable for regular foot traffic, light duty fork lift truck traffic and occasional hard plastic-wheeled trolleys.

• Protects concrete from oil and chemical spillages
• High build with excellent wear and abrasion resistance
• Easy application - no need for solvent/thinners
• Gloss, easy to clean finish
• Non-dusting
• Slip-resistant options available

This product should only be applied by professional, competent and experienced users of epoxy resin flooring systems due to the careful application and preparation these products require.

Substrate Information

PPG EP301 is suitable for concrete and polymer modified cementitious floor screeds. Two coats are normally sufficient but on very porous substrates, an initial coat of PPG EP002 Epoxy Floor Primer should be applied.

Substrate and ambient temperature should be in the range of 10°C to 25°C. In extreme high or low temperatures localised heating or cooling equipment may be required outside this range to achieve ideal application temperature conditions. For heating, use only electric powered systems. Fossil fuel powered heaters emit undesirable amounts of water vapour and CO2. The maximum air relative humidity is 75%. To reduce the risk of “blooming” caused by condensation, the climate above the uncured floor should be maintained at least 3°C above the dew point for at least 48 hours after application.

The surface strength of the concrete base or screed should be assessed using a rebound hammer in accordance with BS EN 12504-2 and should be above 25, and the surface tensile strength should exceed 1.5 N/mm2. Substrates should be clean and free of surface laitance and contaminants such as dirt , dust, loose material, oil, grease, poorly bonded coatings and surface treatments.

An effective structural damp proof membrane should be present and the relative humidity at the surface no more than 75% when measured by the method of BS 8203. New concrete should be a minimum of Grade C35 with a minimum cement content of 300 Kg/m3 and should not contain a water repellent admixture. If the concrete is not dry then PPG EP001 DPM Floor Primer may be used.

Preparation

Inadequate preparation will lead to loss of adhesion and potential failure. With coatings, there is a tendency for the finish to reflect imperfections in the substrate. Grinding, or light vacuum-contained shot-blasting is therefore preferred to planing for these systems. Percussive scabbling or acid etching is not recommended. Weak concrete must be removed and voids filled with a suitable repair material. High spots must be removed e.g. by grinding. If the floor requires levelling or repairing then please choose a suitable product from the PPG Cementitious Flooring Range. Excessively porous concrete should be primed using PPG EP002 Epoxy
Floor Primer. If in doubt, apply a test area first and check subsequent adhesion using appropriate testing methods. Refer to PPG Extra if further information on suitable floor preparation methods is required.

Application

Materials should be stored at 15°C to 25°C for a minimum of 8 hours prior to use. Mechanically pre-mix 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 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.

For best results we recommend that the temperature in the area of installation is kept at a minimum of 15°C. Apply the fully mixed product with a short pile roller and ensure it is worked well into the surface. Take care during application 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 broadcasting the first coat with the appropriate grade of 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 aggregates using a squeegee followed by backrolling with a short pile roller. The coverage rate will depend on surface profile but will be significantly greater than for the first coat.
