Sherwin Williams Resuflor Patch

Sherwin Williams Resuflor Patch is a three-pack easy to use epoxy resin mortar, with excellent mechanical properties. Ideal for rapid repair of concrete surfaces in heavy duty environments.

Formerly Resuscreed PA.

Best Uses

Sherwin Williams Resuflor Patch is a hard wearing and durable concrete patch repair screed, that allows for minimal surface preparation.

• Ease of application
• Excellent abrasion and impact resistance
• Low odour
• Can be used to form coving and falls
• Can be feather edged

Recommended for concrete floor repair in warehouses, chemical production areas, print and packaging floors, engineering facilities and more. Also suitable for the automotive industry and aerospace production areas.

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 Patch 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. Duraplate 301W should be used as a primer onto steel substrates where appropriate.

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

Mix the Resuflor Patch Base with the Resuflor Patch 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 Patch 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.
