Ressi EPO Roll Coat Plus

Ressi EPO Roll Coat Plus

Solvent Based Epoxy Coating

Ressi EPO Roll Coat Plus is a solvent based pigmented epoxy coating material mainly designed for concrete and cementitious surfaces of both floors and walls. Ressi EPO Roll Coat Plus is based on diluted Bisphenol-A based resins and a diluted polyamide based curing agent. The recommended thickness for Ressi EPO Roll Coat Plus is from 50 to 200 microns in a single coat. It is also suitable for a variety of substrates such as wood, metal, fiberglass and selected plastics. Its anti-fungal and anti-bacterial properties make it an ideal coating for vertical wall applications in hospitals and other healthcare facilities.

ADVANTAGES

• Suitable for multi-layer applications
• Easy to apply
• Does not support algae or fungal growth
• Good resistance to sea water and solvents
• Suitable for old and new concrete surfaces

SURFACE PREPARATION

Steel: The base metal should be roughened and preferably shotblasted with grit. Where shot blasting is not possible, pre-treatment may be carried out with tap hammers, rotary wire brushes or by flame scaling. Cleaning with solvent or a strong detergent is advisable to ensure the surface is free from grease, oil, paint and other contaminants. Ressi EPO Roll Coat Plus must be applied before oxidation of steel occurs. Surface defects revealed by blast cleaning should be treated with a suitable repair mortar within the Ressichem patch series compatible with both steel and subsequent epoxy materials.

Concrete / Cementitious Surfaces: Concrete and cementitious surfaces must be dry, clean and free from mold, oil, curing compound, dirt, grease, oil or excessive laitance. Surface should be prepared by suitable mechanical means to provide an open pore surface. Cracks, pinholes, potholes etc. should be routed out and repaired with a suitable epoxy-based crack/void filler from the Ressichem range. The concrete surface should be levelled to produce a roughened flat surface. Undulated floors can be levelled/repaired using suitable floor repairing materials from the Ressichem range prior to application of Ressi EPO Roll Coat Plus. All internal corners should be covered using a suitable epoxy compatible material from the Ressichem range (or as approved by consultant/client). Sharp edges should be rounded off. New concrete floors must be at least 28 days old prior to application. Moisture content must be less than 5%.

MIXING

Ressi EPO Roll Coat Plus is supplied in premeasured packs. Base and hardener should be stirred separately before mixing. After stirring individually, transfer base into a mixing container and mix for 1 minute. Add hardener and mix using a slow speed drill machine fitted with a paddle mixer for 2 minutes to get a uniform mix. Scrape sides, edges and bottom of the container using a spatula and continue mixing for a further 1 minute.

APPLICATION

Apply the mixed material using a suitable squeegee, stiff nylon brush or roller. Work the material into the surface to ensure total absorption into the substrate. Finish using a medium-to-long nap roller.

Ensure required application rates are achieved to maintain minimum dry film thickness per coat. Spray application is also a preferred method to accurately obtain the required dry film thickness.

A minimum of 2 coats should be applied to achieve desired performance. Before each coat, examine the surface for pinholes/cavities. Where pinholes are apparent, fill using Ressi EPO Crack Fill or Patch Epoxy 111 Repair Mortar. Apply the second coat at right angles to the first and preferably in a different color.

For large water tank areas expected to undergo high pressure, strengthen by using 3 coats and fiberglass mesh. Consult Ressichem for details.

LIMITATIONS

At higher temperatures pot life will be reduced. For working in cold climates (<5°C), Ressi EPO Roll Coat Plus containers need to be kept in a hot water bath.
