DUROFLOOR-BI

DUROFLOOR-BI is a two-component, colorless epoxy system with solvents. Thanks to its low viscosity, it can penetrate deep into the substrate and fill pores and hairline cracks. The impregnated surfaces become stable and durable, resistant to abrasion, frost and chemicals, especially to waste, mineral oils and petroleum products. Certified according to EN 13813 and classified as SB-B2,0. CE marked.
DUROFLOOR-BI is used for in-depth impregnation treatment of cement-based substrates, e.g. old and new concrete, cement screeds or plaster, etc. Suitable for floors in car parks, warehouses, laboratories, industries, gas stations, auto repair shops, etc. Also used as a primer for EPOXYCOAT, EPOXYCOAT-VSF and EPOXYCOAT-S epoxy coatings.

Substrate preparation
The flooring surface should be:

  • Dry and stable.
  • Free of materials that might impair bonding, e.g. dust, loose particles, grease, etc.
  • Protected from negative water pressure.

Depending on the nature of the substrate, it should be prepared by brushing, grinding and cleaning with a high-suction vacuum cleaner, etc.

Mixing of components
Components A (resin) and B (hardener) are packaged in two separate, pre-measured containers with fixed mixing ration by weight. The two components are mixed in a clean and dry container – a mixing time of about 5 minutes with a low-speed mixer (300 rpm) is recommended. It is important to stir the mixture thoroughly near the sides and bottom of the container to achieve uniform dispersion of the hardener.

Application – Consumption
DUROFLOOR-BI is applied with a roller, brush or spray in one or two layers, depending on the absorbency of the substrate. The second layer is applied 15 min after the fist one.
Consumption: 150-250 g/m2/layer.
DUROFLOOR-BI may be applied on new concrete (approx. 3 days old) because curing is not disturbed. It may also be applied to slightly wet substrates (moisture content up to 6%) In both cases a low impregnation depth is achieved. If an impregnation depth of about 5 mm into concrete is required, moisture content should be less than 3%.

  • The workability of epoxy materials is affected by temperature. The ideal temperature of application is between +15 oC  and +25 oC, for which the product obtains optimal workability and curing time. Room temperature below +15 oC will extend curing time while temperatures above +30 oC will reduce it. It is recommended to midly preheat the product during winter and store the product in a cool room before application during summer. 
  • DUROFLOOR-BI contains solvents. In case of application in confined spaces, measures for good ventilation should be taken.
  • Non-uniform abrobency of the substrate may cause a non-uniform surface appearance after impregnation.
  • Bonding between succesive layers may be severely affected by moisture or dirt present between them.
  • Epoxy layers should be protected from moisture for 4-6 hours after application. Moisture may whiten the surface or/and make it sticky. It may also hinder hardening. Faded or sticky layers in parts of the surface should be removed by grinding or millin and then laid again.
  • In case recoat time (between successive layers) is longer than expected or in case old floors are to be overlaid again, the surface should be thoroughly cleaned and ground before applying the new layer.
  • After hardening, DUROFLOOR-BI is totally safe for health.
  • Please consult the safety instructions written onthe packaging before use.
