Technical Information
Product Description

EPOFLOOR E250 is a two components solvent free epoxy system consisting of a colored base resin, hardener. It is suitable for chemical protection coverings of industrial pavements, reinforced concrete and metallic structures.

EPOFLOOR E250 adheres perfectly to a variety of supports like: concrete, metal, wood, stoneware, etc. Once cured, the product transforms to an anti-dust, chemical resistant continuous membrane. The applied coating is characterized excellent abrasive resistance and mechanical strength.

Advantages

Solvent free and odorless

Durable and low maintenance cost

Excellent resistance to a wide range of chemicals

High mechanical strength, with excellent abrasion resistance

Excellent adhesion to the substrate. Bonding strength is greater than cohesive strength of concrete

Less labour cost to achieve the required thickness (250 micron per coat)

Packaging, Coverage / Consumption

EPOFLOOR E250 is supplied 4 and 15 Liter Kits.

Consumption: 5-6 m² / liter according to the porosity of support

Shelf Life & Storage

Keep in tightly closed containers and in sheltered and dry place with a temperature between +5°C and +35°C. Shelf life is 12 months from date of production if stored properly.

Application Information
Instructions for use

Priming

Highly porous concrete or concrete containing micro-silica must be treated with PRIMER POXY FF, a Solvent-free high performance Epoxy primer.

In that case the primer should be applied by brush or roller on to the cleaned surface area (particularly hidden surfaces) at a rate of 5-6 m²/Liter.

The primer should be left to achieve a tack-free condition before applying the top coat. A second coat of primer may be required if the substrate is excessively porous.

In case of Metal substrates, the surface shall be treated with one coat of PRIMER POXY before the oxidation process occurs.

Mixing

EPOFLOOR E250 is supplied in two pre-weighed packs (Component A – Base and Component B – Hardener) which are ready for immediate in-situ use. Stir in both components before use.

Transfer the entire contents of component B (Hardener) into the component A (Base) can and mix with low speed drill and paddle (200 – 300 rpm) for 2-3 minutes till obtaining a mix with uniform consistency. Scrape the sides and bottom of the can during mixing to ensure homogeneity.

Application

Apply two coats of EPOFLOOR E250 with a roller, squeegee or airless spray to the primed tack free surface at a consumption rate of 5-6m2/Liter.

Each coat will be a minimum of 200-250 microns thick. The second coat shall be applied after the first coat is completely dry.

The total dry film thickness of the coating shall be a minimum of 500 microns.

For anti-slip flooring, silica sand (with suitable size) can be broadcasted on first coat in order to achieve leatherette like finish.

For heavy traffic areas such as drive lanes, ramps, turn areas, or other areas subjected to high abrasive traffic, apply a third coat EPOFLOOR E 250.

Cleaning

Tools and equipment should be cleaned with SOLVENTE 10 immediately after use. Hardened material should be removed mechanically.
Spillages should be absorbed with sand or sawdust and disposed of in accordance with local regulations.

Recommendations

  • EPOFLOOR E250 should not be applied onto surfaces likely to suffer from rising dampness or relative humidity > 70%
  • EPOFLOOR E250 should not be applied at temperature below +5°C
  • EPOFLOOR E250 should not be applied at asphalt floors or PVC tiles
  • EPOFLOOR E250 should be applied internally. If used exteriors it is strongly recommended to cover with one or two coats of EPOFLOOR E250
Surface Preparation

Concrete Substrates

The surface of the concrete to be prepared shall be sound, clean and uncontaminated.

This preparation shall be such as to leave a sound exposed concrete surface free from dust, loose particles and any deleterious matter. If the concrete surface is defective or has laitance, it must be cut back to a sound base. Excess laitance deposits are best removed by light mechanical scrabbling, grinding or grit/captive blasting followed by vacuum cleaning to remove dust debris.

Any blowholes, chipping or similar surface imperfections shall be repaired using EPOFINISH C, a solvent free epoxy resin repair mortar. Allow the repair material to harden.

Expansion joints shall be repaired using EPOMORT HS, a High strength solvent free epoxy mortar.

New concrete or cementitious surfaces should be allowed to cure and have moisture content not exceeding 5%. Old or existing floor should be refurbished mechanically to ensure clear sound substrate.

Metal Substrates

All metal substrates should be blast cleaned to achieve a minimum of Sa2 ½ standard of roughness, an angular amplitude of at least 75 microns for pedestrian traffic and 100 microns for vehicular traffic. The coating system must be applied over the blasted steel surface immediately. If the standard of the surface falls below Sa2 ½ then the steel must be reblasted.

Additional Information
Health & Safety

During application, wear appropriate protective clothing, goggles, gloves and respiratory equipment if necessary.

 

In case of contact with skin, rinse with water and again wash thoroughly with soap and water. In case of contact with eyes, rinse with plenty of water and seek medical advice accordingly.

 

If ingested, obtain medical attention immediately. Do not induce vomiting.
