BIF EP Flow
BIF EP-Flow is a medium duty flow applied epoxy floor topping for use on concrete and polymer modified cementitious screeds. BIF EP-Flow provides excellent levels of durability, impact, abrasion and chemical resistance.
It's easy to clean, smooth, gloss finish makes the product ideal for environments such as the food, beverage, engineering and chemical industries. BIF EP-Flow is ideal for clean rooms, retail showrooms, dry manufacturing process areas, warehousing & other areas where a flat, smooth working surface is needed.
Seamless, smooth, gloss finish. Synthetic resin flooring will generally follow the profile of the underlying substrate because of their method of application and their relatively low thickness. This system should only be installed by experienced installation teams.
- Flow applied - rapid installation
- Resistant to general chemical spillages
- High wear & abrasion resistance
- Easy to clean
Nominal 2 – 3 mm
Ideal ambient and substrate temperature range is 15 - 25 ºC. 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 3 ºC 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 assessed using a rebound hammer in accordance with BS 1881-202 should be above 25 and the surface tensile strength should exceed 1.5 N/mm2 . 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.
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. The substrate should be finished to a surface regularity when tested according to BS 8204-1 of class SR2 otherwise a scratch coat will be required.
Priming should be carried out using BIF EP-Primer 100 or 110 at approx 5m2 /kg depending on substrate porosity. Apply using a medium nap roller ensuring complete coverage and avoiding pooling. Surfaces must be fully sealed, so when cured, if there are dry patches, 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 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 25 oC. 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 1 - 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, lumpfree 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. Extended or vigorous mixing should be avoided in order to minimize air entrapment.
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. The cured product should be protected from other trades (polythene should not be used, as protection sheets must be breathable - Corex Sheets recommended).
Protect the installed floor from dust, traffic, damp, condensation and water for at least 24 hours or longer.
