Product Description

Please note, this product has now been discontinued. Contact our technical team for a suitable alternative.

PPG EP4501 is a medium duty, flow applied epoxy floor topping for use on concrete and polymer modified cementitious screeds. PPG EP4501 is formulated to give the user a floor that has excellent durability, impact, abrasion and chemical resistance.

Best Uses

PPG EP4501 has an easy to clean, smooth, gloss finish. This makes the product ideal for use in environments such as the food, beverage, engineering and chemical industries. PPG EP4501 can also be used in clean rooms, retail showrooms, schools, hospitals and hotels.

  • Flow applied - rapid installation
  • Resistant to general chemical spillages
  • Non-dusting
  • Seamless
  • High wear & abrasion resistance
  • Easy to clean

This is a professional grade product. Promain recommend use of qualified professional application only.

Application Conditions

Ideal ambient and substrate temperature range is 15 - 25ºC. Localised heating (electric powered warm air blower) or cooling equipment may be required outside this range to achieve ideal temperature conditions. The aggregate can be stored in a cool area (or warm area in the case of low ambient temperature) in order to control product temperature and working life. The substrate and uncured floor must be kept at least 3ºC above the dew point to reduce the risk of condensation or blooming on the surface, from before priming to 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. For further information on PPG EP001 see the appropriate Product Data Sheet.


Inadequate preparation will lead to loss of adhesion and failure. In flow applied systems 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. Percussive scabbling or acid etching is not recommended. The substrate should be finished to a surface regularity when tested according to BS 8204-1 of class SR1 otherwise a scratch coat or other method of levelling may be required. If the floor requires levelling or repairing then please choose a suitable product from the PPG Cementitious Flooring Range. Refer to PPG Extra if further
information on suitable floor preparation methods is required.


Priming, and sealing of the surface is essential when laying this type of product. Priming should be carried out using PPG EP002 Epoxy Floor Primer at 4 - 8m2/Kg depending on substrate porosity. Apply using a medium nap roller ensuring complete coverage and avoiding pooling. If, when cured, there are dry patches, or voids in the coating, a further primer coat is required. Allow to cure completely before proceeding. If the primer has been left to cure for >48 hours then the primer surface should be lightly mechanically abraded and the area re-primed. Failure to do so may result in pin-holing of the surface topping.


Prior to mixing, the temperature of the three components must be between 15 and 25ºC. 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 (200 - 500 rpm) for 2 minutes until homogeneous. Decant the mixture into a suitable mixing vessel and gradually add the aggregate component whilst continuing the mixing action. When all the aggregate has been added, mix for a minimum
of 3 minutes until a uniform coloured, lump-free mix is obtained. Care should be taken to ensure that any material adhering to the sides, bottom and corners of the mixer is thoroughly blended in. Unduly extended or vigorous mixing should be avoided in order to minimize air entrainment.

Apply the mixture immediately onto pre-primed areas, spread to the required thickness using a steel float then de-aerate using a spiked roller. Continue spiked rolling until air is released finishing well before the material begins to gel. An anti-slip system may be achieved by applying EP301 to the surface and whilst still wet apply the appropriate grade of kiln dried silica sand at 3-4 Kg/m2 to the surface. Allow to fully cure then remove all excess sand with a stiff broom and vacuum. Apply a coat of PPG EP301 High Build Epoxy Floor Coating to encapsulate the aggregates using a squeegee followed by back-rolling with a short pile roller. The coverage rate of the PPG EP301 will depend on surface profile.
