RonaFloor Epoxy Floor Screed is a high performance epoxy resin mortar for heavy duty floor toppings. Minimum thickness is 5mm, typical screed thickness is 5-10mm.

RonaFloor Epoxy Floor Screed offers good mechanical resistance and will resist attack from spillage of a range of industrial chemicals including acids, alkalis, oils and fats.

Substrate Preparation

To achieve optimal adhesion it is essential that RonaFloor Epoxy Floor Screed is applied to structurally sound, clean and dry substrates.

Surfaces must:

• Be prepared after making good any defects in the floor, ensuring that friable materials are removed and replaced (for fast cure repairs refer to RonaFloor Repair 1 Hour data sheets)
• Be prepared by captive shot blasting, scabbling or similar approved method to produce lightly textured, laitance free surfaces
• Be cleaned to remove grease, oil and dirt
• Be allowed to dry after washing
• Be vacuum cleaned, to remove loose shot and other loose materials

New concrete or screeds should be allowed to dry prior to coating. RH at the surface must be below 75% when measured with a hygrometer, or have a moisture content less than 5%.

Application Conditions

The application characteristics of RonaFloor Epoxy Floor Screed are adversely affected by low temperature; viscosity and curing time will increase. Therefore the material should ideally be stored, mixed and applied at 15°C to 20°C.

At lower application temperatures the material should be stored at or warmed to 15°C to 20°C prior to use.

Application characteristics are severely affected below 10°C, minimum application temperature is 5°C.

In areas exposed to sunlight, the substrate can be hotter than the air and material temperature, which may adversely affect the workable life of RonaFloor Epoxy Floor Screed.

Substrate Priming

Prime prepared surfaces with RonaFloor Epoxy Primer, coverage up to 25m² per 4.5kg pack, depending on substrate porosity and texture.

RonaFloor Epoxy Primer must not be applied to damp substrates.

A single coat of RonaFloor Epoxy Primer MT with a kiln-dried sand blinding may be used to prime damp surfaces or two coats of RonaFloor Epoxy DPM may be used to prime drying concrete and polymer screeds, see separate technical data for usage instructions.

Mixing

RonaFloor Epoxy Floor Screed is supplied as a three component material.

Remove all materials from the container; pour the entire contents of the resin and and hardener containers into a mixing vessel or, add component B to component A and mix thoroughly with a slow speed drill and MR 3 type paddle.

Gradually add the supplied aggregate to the mixed resin and mix in a forced action mixer such as CreteAngle, Baron or Daines Mixall until homogeneous.

10kg of single size 5-10mm kiln-dried aggregate may be added to 25kg of product for application thicker than 25mm.

Single packs may be mixed with a 1kW slow speed drill fitted with an MR4 type paddle.

The product has been designed to be used as a full pack; do not part mix.

Mixing time should be approximately 3-4 minutes. The material will have a pot life of approximately 30-45 minutes at 20°C.

Application

Place the mixed material onto the wet RonaFloor Epoxy Primer. If the primer has hardened it must be thoroughly abraded if fully cured, before application of a further coat.

Spread evenly in one direction with a steel float, ensuring good compaction. The surface should be closed and trowel marks removed.

Overworking will adversely affect the appearance of the surface.

Sealing

RonaFloor Epoxy Floor Screed requires sealing, especially when used in wet environments. A choice of seal coats from the RonaFloor range can be applied as the final finish. Over-sealing will affect slip resistance.

Cleaning

Clean all tools and equipment with RonaDeck Low VOC Tool Cleaner/Trowel Finishing Aid to remove uncured resin.

RonaFloor Epoxy Floor Screed is a hardwearing, durable, epoxy floor screed for medium and heavy duty industrial and commercial floors.

The surface is lightly textured to provide slip resistance. Slip resistant resin floors cannot be cleaned by traditional methods and should be cleaned with a scrubber dryer, cold water power washer or similar.

For additional information please refer to FeRFA Guide to Cleaning Resin Floors (FeRFA Guidance Note No:6).

In clean rooms and other areas where hygiene is important, RonaFloor Epoxy Floor Screed may not be suitable.

To ensure the suitability of any product, a sample area should be laid and its performance and ease of cleaning assessed.
