Technical Information
Product Description

EPOFLOOR CF is a two component polyurethane waterproofing membrane. It has good characteristics of impermeability, elasticity, crack bridging and resistance against abrasion and chemicals.

After curing, the product transforms into an elastic, continuous, membrane suitable for use in traffic coating systems to provide crack bridging and
waterproofing capability.

EPOFLOOR CF adheres perfectly to varied supports as concrete, asbestos cement, wood, metallic surfaces, etc.

Advantages
  • Tough and durable
  • Very good abrasion and chemical resistance
  • Good adhesion to most substrates
  • Excellent workability
  • Easy application
  • Economical
  • Free of pitch or bitumen modification
  • Superior wear and weather ability for parking deck and contaminating areas
Packaging, Coverage / Consumption

EPOFLOOR CF is available in 4 and 15 Liter kits.

Consumption: 2.5 m2/Liter at 400 microns DFT

Application Information
Instructions for use

Priming

Highly porous concrete or concrete containing micro-silica must be treated with PRIMER PU, a high performance Polyurethane primer. PRIMER PU shall be used as a primer coat for polyurethane based car park deck systems.

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/L.

The primer should be left to achieve a tack-free condition for 6-8 hours before applying the top coat. A second coat of primer may be required if the substrate is excessively porous.

Metal surface must be perfectly cleaned up to white metal by sand blasting, and then treated with one coat of PRIMER PU before the oxidation process begins again.

Mixing

EPOFLOOR CF 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.

Add the hardener (Part B) to the Base (Part A) container and mix for 20-30 seconds using a heavy duty, slow speed drill fitted with a mixing paddle.

Transfer the mixed material to another pail and
again remix for 30 seconds.

Application

Pour EPOFLOOR CF onto the primed surface at a rate minimum of 2.5 m²/Liter and spread evenly with a notched trowel. Continuous spiking with a spiked roller should be done to remove all entrapped air. Spiking adjacent layers is recommended at 50% overlaps. Spiking shall stop as soon as the coating starts to set.

While the coating is still wet, broadcast QUARTZO NO.2 at approximately 0.6-2.0 kg/m² (depending on the wearing coat thickness). After 24 hours cure, excess aggregate shall be brushed away.

Cleaning

Tools and equipment should be cleaned with SOLVENTE 10 from Colmef 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

  • The curing time of EPOFLOOR CF is influenced by the ambient, material and ambient temperatures.
  • At high temperatures, chemical reactions are speeding up thus shortens the pot life, open time and the curing times.
  • EPOFLOOR P CF should not be applied on surfaces with a risk of rising dampness.
  • Don’t mix more material than can be used within the pot life of mixture.
Surface Preparation

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.

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.

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.
