Resupol can be applied from 10-50mm and can be used to lay falls. It provides a superb surface for applying further protective coatings and is ideal for use on hard-wearing industrial floors.

Resupol works well as a base for Resucrete, Resuscreed and Resuthane.

Recommended Uses

• Factory flooring
• Warehouses
• Food and drink industry

Preparation

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

Existing Concrete Floors: Remove all dirt, oil, grease, old paint or any 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. Make sure all residue of detergent is washed and removed by rinsing with clean water. Local repairs should be carried out using Resupatch or Resuscreed 45.

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 advice on intercoat adhesion and suitability, as it may not be compatible with existing floor coating.

Priming

Priming can be achieved in several ways, depending on site conditions and requirements. High bond strengths can be achieved by using Resupol or R.S. Cemprime. Alternatively, a slurry coat can be used. Normally this will be one coat of Resupol and cement mixed one to one by volume, applied at a rate of approximately 3m sq. per litre of latex. (typical potlife for this material is 1-1.5 hrs.) Care should be taken to ensure that the primer is laid off smoothly and evenly and worked into the surface, avoiding leaving pools of material on the floor. Equipment used should be cleaned with clean, cold water periodically and at the end of the application.

Only prime the areas to be screeded during that working period. Extremely porous surfaces require an additional sealer coat of one-part Resupol to four-parts water, applied prior to the application of the primer.

Application

It is important to ensure that the materials used are of suitable quality and consistency. Sharp sand should be clean, well washed and selected on the basis of mix design.

Portland cement should be fresh, free from lumps etc. Aggregates should be dust-free and graded such that they are appropriate to the thickness of materials being laid.

Mix design is dependent on thickness and intended use:

                                        Levelling Screed               Heavy Duty Topping

Portland Cement                         1                                        1

Sands                                       3.5                                    1.75

Washed Granite                           0                                     1.75

Resupol                                     0.2                                     0.2

Water                                 As required                           As required

This equates to 10 litres of Resupol per 50 kg cement. Improved strength can be achieved by increasing the Resupol content to 15 litres per 50 kg, offsetting the volume of water used.

This product contains a defoamer and is formulated for this to be effective in the production and use of the product. However, over-mixing will result in air entrapment and bubbles forming in the bulk of the laid screed.

Mix to a smooth, even consistency free from lumps. When mixed, the screed will have a working life of approximately 30 minutes. It is important therefore, to ensure that the mixing capability is consistent with the laying process.

Lay the screed or topping direct into the wet primer, laying off with a rake or similar, and compacting with a screed bar prior to finishing with a steel float. Where large areas are involved, it is essential that this is done as the work proceeds, and that the application is planned to enable working in bays. These bays should align with the movement or other existing joints.

Usage

Usage is dependent on the aggregates selected. Based on the formulation above being applied to a smooth sealed surface, for an area of 100 m² at 10 mm thickness, 2000 kg of mix, requiring 85 kg of Resupol.
