Industrial Flooring

Surface preparation

The surface of the concrete to be repaired 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. 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.

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.

Mixing

EPOFLOOR ECT is composed of three components that must be mixed at the moment of use and applied at the specified pot life. Stir the base (Component A) and pour onto the empty 20 Liter pail. Add the curing agent (Component B) and mix both liquids thoroughly. Sand (Component C) should then be added to the mixture while stirring continuously.

Application

Pour the mixture onto the prepared substrate at a consumption rate of 0.33 m²/Liter at a thickness of 3.0 mm. Spread the product evenly using steel trowel or squeegee. Divide the deck into approximately 2 meter wide strips masked with 2 inches tape or timber battens. This enables to achieve clear edge whenever masking tape or timber battens are removed while the coating is still soft. The next strip could be applied alongside.

The use of wet film gauge is recommended to make sure the correct thickness and material usage. The surface dressing aggregate, ALUGRIT must be applied immediately after laying EPOFLOOR ECT. The slurry coating is blinded to saturation by allowing ALUGRIT aggregate to fall vertically until no slurry is visible.

Masking tape must be removed before the coating has cured.

Allow EPOFLOOR ECT to cure for the period of 24 hours at +25°C before opening to foot traffic.

Cleaning

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

Recommendations

• Do not throw aggregate across the slurry as this may cause ridges.
• EPOFLOOR ECT should not be applied when the relative humidity is greater than 80% or the ambient temperature is expected to fall below +5°C.
• EPOFLOOR ECT slurry should not be applied on ramps with a slope greater than 5%.

Chemical resistance

Fully cured ECT samples have been tested in a wide range of aggressive chemicals commonly found in industrial environments. Tests were performed in accordance to ASTM D543 standards over 7 days at +25°C.
