For complete safety and handling information, please refer to Material Safety Data Sheets (MSDS) prior to using this product.

Any residual trowel marks may be removed when the screed is dry by rubbing the surface with a carborundum stone.

Note: The long-term durability of any resin floor system is determined by the adhesive bond achieved between the flooring material and the substrate. It is most important therefore that substrates are correctly prepared prior to application. The substrate should have a moisture content of less than 5% and must be at least 3°C above the dew point to reduce the risk of condensation or blooming on the floor finish. The ambient relative humidity should not exceed 95%. The minimum substrate temperature is +15°C and the maximum substrate temperature is +35°C.

The clean, textured surface can be achieved by shot-blasting, Blastrac, scarifying, or grit-blasting followed by vacuum cleaning.

New concrete floors:

These should normally have been placed for at least 28 days Floors should be sound and free from contamination such as oil and grease, mortar and paint splashes or curing compound residues. Excessive laitance can be removed by the use of Mechanical methods. Dust and other debris should then be removed by vacuum cleaning.

Old concrete floors

Surfaces should be structurally sound with a direct tensile strength of more than 1.5MPa via a pull-off tester with a load rate of 100N/s. A clean substrate is essential to achieve maximum adhesion. As for new concrete floors dry removal of laitance by use of Mechanical methods is preferable. Oil and grease penetration should be removed by the use of a proprietary chemical degreaser or by hot compressed air treatment. Any damaged areas or surface irregularities should be repaired using MRO 4019 – Konkrete Putty.

Steel surfaces

Steel surfaces should be degreased and grit blasted to SA 2 ½ immediately prior to application. The prepared surface should be treated with one coat of MRO 9021 – Primer DK solvent-free epoxy primer.

All surfaces are primed with MRO 9021 – Primer DK, sol vented epoxy primer designed for maximum absorption and adhesion to concrete substrates. Add the entire contents of the hardener tin to the resin tin and mix the two primer components thoroughly for at least 2 minutes – under no circumstances should part mixing be considered. Once mixed, the primer should be applied immediately to the prepared substrate using stiff brushes and/or rollers. The primer should be well ‘scrubbed’ into the substrate to ensure full coverage, but care should be taken to avoid over-application or ‘ponding’. Allow the primer to dry before proceeding to the next stage, do not proceed whilst the primer is ‘tacky ‘as this will lead to unsightly marks on the finished surface. Porous substrates may require a second primer coat – when the first coat is directly absorbed into the substrate– but minimum over-coating times must still be observed.

MRO 9012 – DIELECTRIC KOTE (52 KV)

Electrical Insulation Coating

MRO 9012 – Dielectric Kote flooring is supplied in four pre-weighed packs (resin, hardener, aggregate, and color pack) which are ready for immediate on-site use. Part mixing of these components is not acceptable and will affect both the performance and appearance of the finished floor. Mixing should be carried out using either a forced action mixer; or a heavy-duty, slow-speed drill fitted with a mixing paddle. The components should be mixed in a suitably sized mixing vessel. The color pack should be added to the base container and mixed for 15-30 seconds, until homogeneous. Then add the hardener and mix for a further 30 seconds, until an even color and texture are obtained. Hereafter, the contents of the graded aggregate pack should be slowly added, and mixing carried out for a further 3 minutes until a completely homogenous material is obtained. Note: If required transfer the mixed material into the larger mixing vessel and re-mix for 30 seconds. Mixing in this way will ensure product uniform color consistency. Once mixed, the MRO 9012 – Dielectric Kote will generate heat and lose working time if it is left in the mixing container or otherwise kept in bulk. Once the mixed material has exceeded its pot life, the viscosity and the characteristics of the product will change and any unused product should be discarded at this time. Do not steam clean or use hot water above 50ºC to wash the surface. Do not add solvent thinners at any time.

The mixed material should be applied on to the prepared and primed floor as soon as mixing is complete using a serrated or notched or flat trowel to a typical thickness of 1.5 mm minimum. Care should be taken not to overwork the resin, spreading evenly and slowly. Immediately after laying, the material should be rolled, using a spiked nylon roller, to remove slight trowel marks, and to assist air release. The rolling should be carried out using a ‘back and forth’ technique along the same path. An overlap of 50% with adjacent paths is recommended. Further light rolling may be required to remove surface imperfections, or for subsequent release of trapped air, but should be prior to the setting of the product Ensure application is a continuous operation and laying is within 15 minutes of mixing and spike rolled within 5 minutes of laying. Care should be taken to ensure that a continuous film is achieved.

Note: Protect walls and columns against resin splashes using masking tape and polythene sheeting.

The consumption of MRO 9012 – Dielectric Kote depends on the number of coats, surface profile, porosity, loss, and wastage.

Expansion Joints

Expansion joints in the existing substrate must be retained and continued through the MRO 9012 – Dielectric Kote topping.

High-Temperature Workings

It is suggested that, for temperatures above 35°C, the following guidelines are adopted as good working practice:

Store unmixed materials in a cool preferably air-conditioned environment, avoiding exposure to direct sunlight. Preconditioned materials at 20-25°C will reduce the possibilities of flash setting and other defects.

Keep equipment cool, arranging shade protection if necessary. It is especially important to keep cool those surfaces of the equipment which will come into direct contact with the material itself.

Try to avoid application during the hottest times of the day. If necessary provide shade over the area where the application will take place.

Make sufficient material, plant, and labor available to ensure that application is a continuous process.

Low-Temperature Workings

It is suggested that, for temperatures above 15°C, the following guidelines are adopted as good working practice:

(i) Store unmixed materials in a heated room in hot weather conditions. Preconditioned materials at 20-25°C will reduce the possibility of slow setting and other defects.

(ii) Make sufficient material, plant, and labor available to ensure that application is a continuous process.

MAINTENANCE

The service life of a floor can be considerably extended by good housekeeping practices.

Good housekeeping and regular cleaning is essential in order to maintain the performance of MRO 9012 – Dielectric Kote. It is particularly important in areas that are subject to regular spillage.

Spillages should not be allowed to dry which results in higher concentrations of the materials, which may lead to early failure. Regular cleaning of the surface with a rotary scrubbing machine in conjunction with a water-miscible cleaning agent or hot water washing at temperatures up to 50°C is recommended.
