Sherwin Williams Resuflor Screed

Sherwin Williams Resuflor Screed is a heavy duty, epoxy resin floor screed, with high chemical resistance and strong colour definition.

Best Uses

Sherwin Williams Resuflor Screed is recommended for industrial floor use in various industries including Chemical production and storage, Printing and packaging areas, Engineering facilities, Automotive industry, Aerospace production areas and Industrial workshops.

• Hard wearing and durable
• Suitable for industrial use
• Ease of application
• Can be used as a repair system
• Excellent abrasion and impact resistance
• Low odour
• Can be used to form coving and falls
• Can be feather edged

Sealing is necessary where impervious finishes are required. The Resuflor Screed formulation uses an aggregate component free of crystalline silica, promoting a more environmentally friendly product with less dust compared to traditional epoxy resin screeds.

Application

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 making 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 the existing floor coating. Where Resuflor Screed is applied to masonry/concrete surfaces, care must be taken to ensure that surface preparation is thorough but does not disfigure the surface.

Priming

Open and porous substrates should be primed with one or two coats of Resuprime ST to ensure a sealed surface. Substrates should be dry with a moisture content of 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. Please refer to the table below for required number of coats to achieve proper moisture tolerance.

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

Mixing and Application

Mix the entire contents of the Resuflor Screed Base with Resuflor Screed 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. 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.

Resuflor Screed is usually sealed with Sherwin Williams Resuflor GC UVR and/or Sherwin Williams Resuflor HB applied by roller, please see SW System Guides for details on this.
