RSL Resuflor Screed Epoxy Resin Concrete Mortar Overview

RSL Resuflor Screed is a 3 pack epoxy resin mortar designed for rapid concrete repair in heavy duty environments.
 

• Hard wearing durable repairs for Industrial Use
• Ease of application
• Minimum surface preparation
• Can be feather edged
• Excellent abrasion and impact resistance
• Concrete like in appearance
• Dust-free 

Preparation

New concrete Floors: Must be clean, sound, dry, fully cured & surface laitance removed 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 detergent is washed & removed by rinsing with clean water.

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.

Where overcoating 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 in the individual data sheets, the coating in each stage should be tack free, but not fully cured. If fully cured, then mechanical preparation is required to ensure intercoat adhesion.

Priming

Open and porous substrates may require priming with RSL Resuflor WB, also Resuprime NT may be used as primer on dry substrates only, with less than 75% ERH reading. Where the relative humidity of a substrate exceeds 75% ERH, RSL Resuprime MVT should be specified & 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 1 coat of Resuprime MVT at 200 microns per coat
85-92 2 coats of Resuprime MVT at 200 microns per coat
92-97 3 coats of Resuprime MVT at 200 microns per coat

For further information please refer to recommended individual product data sheets.

Application

The ambient temperatures of the areas should not be allowed to fall below 15°C throughout the application and the curing period, as this could have an adverse effect on the appearance & colour of the system. Surface temperature must be above 10°C. Where possible it is recommended that the application area is heated to a minimum temperature of 15°C to allow the ambient and substrate temperature to stabilise prior to installation.

Mixing: Pre-mix the coloured base component to a uniform consistency, then mix the entire contents of the base with the hardener. If a separate mixing bucket is being used, mix thoroughly ensuring all contents of both components are removed from the buckets supplied. Add the aggregate component slowly whilst mixing. Mix using an electric mixer for approximately two to three minutes until the three components have fully combined. For larger units a forced action mixer may be required to fully combine the aggregate into the resins.

RSL Resuflor Screed should be worked with a trowel or float to achieve a dense, compacted finish. This is best achieved by the application of smooth even pressure in one direction, gradually increasing the pressure as the material compacts and beds down. Over-working the material will draw fines to the surface which may result in resin-rich spots and finish variations.
