Resuflor Q Screed (formerly known as Resuscreed QS and Decora MS) is a decorative epoxy resin floor screed incorporating multi-coloured aggregates, designed to produce a hard wearing, attractive, impervious sealed surface. The system is applied at 4mm minimum thickness and then sealed with clear resins to provide a matt or gloss finish. See below for system information and application instructions.

For more aggregate see RSL Resuscreed QS Aggregates only.

Product Information

Products required for this system

• Primer : Resuprime ST or use Resuprime MVT on damp surfaces where required
• System : Resuflor Q Screed at required thickness
• Surface Seal : Resuflor GC-UVR followed by Resuflor HB Clear and an optional coat of Resupen WB Clear Matt where a matt finish is required.

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/mm² 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 and make sure all residue of detergent is washed and removed by rinsing with clean water. Local repairs should be carried out using Resuflor Patch.

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.

Timber Floors

Must be clean, sound, dry . Old clear varnish/topcoat must be removed/sanded prior to application, as it may affect the intercoat adhesion with Resuflor Q Screed.

Priming

Open and porous substrates may require priming with Resuseal WB, also Resuprime ST 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 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:

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 and 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 ideally to allow the ambient and substrate temperature to stabilise prior to installation.

Mixing:

Mix the entire contents of base with the hardener, if using a separate mixing vessel then ensure the entire contents of the base and hardener are emptied out of the buckets supplied. Pour the combined base and hardener into a rotary drum mixer and add the aggregate component steadily, until a homogeneous mix of the three components is achieved. The mixed unit should be applied immediately after mixing. Apply to pre-primed areas and level between battens as necessary with a steel float, alternatively a sledge can be used set at the required thickness.

Resuflor Q 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, colour and finish variations.

The surface should be protected from temperatures of less than 10°C and moisture in the early stages of cure.

Coving can be formed in advance of the floor laying process, and or at the same time. Where laid in advance a join line may be visible between the cove and floor.

At 100mm nominal height, one 28 kg unit of Resuflor Q Screed will typically form up to 10 linear meters of coving which must be applied onto a wet primer coat of Resuprime MVT to achieve maximum adhesion.

Seal Coats:

Resuflor Q Screed is normally sealed with the application, by squeegee, of one coat of Resuflor GC-UVR at a rate of 3-4m²/kg. This would be followed by a coat of Resuflor HB Clear at a rate of 3-5m²/kg. The optional Resupen WB Clear Matt is applied at a rate of 10m²/L to provide a flat matt finish.
