The game-changing, technological Elladur SF are very versatile systems. They can be created with anti-slip finishes and decorative finishes by incorporating the relevant flakes and aggregates to your flooring needs.

Recommended Uses

• Where a fast turnaround at a low temperature is required
• Decorative floors
• Domestic floors
• Medical areas
• Commercial environments
• Industrial floors
• Where high-build, UV stable coatings are needed

Preparation

New Concrete Floors: New concrete must be clean, sound, dry and fully cured and surface laitance removed preferably by vacuum enclosed shot blasting or mechanical grinding. A minimum strength of 25N/mm sq. is required.

Timber Floors: Must be clean, sound and dry. Old clear varnish/topcoat must be removed/sanded and surface must be primed prior to application.

Existing Concrete Floors: Remove all dirt, oil, grease old paints or other surface contaminants by vacuum enclosed shot blasting, scarifying or mechanical grinding. Fats, oils or greases must be removed by mechanical means and detergent washing. Local repairs should be carried out using Resuscreed PA or Resuflor Screed.

Existing Floors (previously coated): All previous coatings and loose floor paints must be removed by mechanical preparation, as described in the above section and primed as specified. If the old resin flooring cannot be removed, then please consult with our technical team for advise on intercoat adhesion and suitability, as it may not be compatible with the existing floor coating.

Where over-coating other systems such as epoxy coatings or screeds, as part of a specified composite system in the data sheets, please follow the recoat time as stated. These should be tack free, but not fully cured. If fully cured, then mechanical preparation is required to ensure intercoat adhesion.

Where Elladur SF is applied to masonry/concrete surfaces, care must be taken to ensure that surface preparation is thorough but does not disfigure the surface.

Priming

Elladur SF may be applied to an existing resin floor system, where a primer is not required. When applied direct to porous substrates such as concrete, the surface must be primed with Elladur SF to ensure good adhesion to the surface.

Where the relative humidity of the substrate exceeds 75%, Resuprime MVT should be specified and selected on the basis of hygrometer readings in accordance with BS 8203.

The number of coats to be applied is chosen in accordance with the following table:

 ERH% Required Coating Thickness
75-85 1coat of Resuprime MVT at 200 microns per coat
 85-92 2coats of Resuprime MVT at 200 microns per coat
92-97 3coats of Resuprime MVT at 200 microns per coat

Application

Mixing: Pre-mix the base component to a uniform consistency, then add the entire contents of the hardener to the base and mix by using a slow speed electric mixer for approximately two minutes to achieve consistent mixture. Do not use a separate mixing bucket as it may affect the mixing ratio.

A rubber blade and/or a short-haired roller can work best for this application, to help avoid incorporating extra air and moisture in the coating. It is important to ensure that the recoat times are observed, with a maximum recoat of 8 hrs measured at 20°C substrate temperature and 50% relative humidity.

For other conditions please consult with our technical team. It is strongly recommended to apply the second coat as soon as the first coat has lost the tackiness to achieve the maximum adhesion. If the maximum recoating interval is exceeded, then the surface must be prepared and roughened to ensure intercoat adhesion.
