Sherwin-Williams Floorcoating Resutop

Sherwin-Williams Floorcoating Resutop

Two pack, pure epoxy coating

Resutop is a two-pack, high solid, high-build epoxy coating for application as a chemical resistant heavy-duty floor coating. The coating will provide a smooth gloss finish to which anti-slip aggregate can be added if required. Applied by squeegee, roller and paintbrush the product is low odour producing a seamless, hard wearing, hygienic floor finish.

Advantages

• High-build finish
• High solids
• Hygienic and easily cleaned
• Good colour stability
• Excellent slip resistance with the addition of selected aggregates
• Ease of application
• Excellent high gloss finish
• Low odour
• Excellent adhesion
• Excellent Ease of Decontamination

Recommended Use

• Food processing and beverage areas
• Chemical plant rooms
• Engineering workshops
• Aviation and automotive areas
• Factory units and warehouses
• Nuclear facilities
• Excellent for all demarcation and walkways
• Used as a seal coat for various SW flooring systems

Surface 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 Resuscreed PA.

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 inter-coat adhesion and suitability, as it may not be compatible with the existing floor coating.
Where Resutop 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 may require priming with Resuseal WB, also Resuprime ST may be used as a primer on the dry substrates only with less than 75% ERH reading.

Where the Relative Humidity of a substrate exceeds 75% ERH Resuprime MVT should be specified. Please refer to the table below for the required number of coats to achieve proper moisture tolerance.

ERH% Required Coating Thickness
75-85 1 coat of Resuprime MVT at 200 µm per coat
85-92 2 coats of Resuprime MVT at 200 µm per coat
92-97 3 coats of Resuprime MVT at 200 µm per coat
For further information please refer to recommended individual product datasheets.

Application

Mixing: 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. Mix using a slow speed electric mixer for approximately two to three minutes until the two components are fully combined.

The mixed unit should be applied immediately by roller, brush or squeegee with a consistent procedure. Floor areas should be cross-rolled to ensure even application and to minimise roller marks.

Application Conditions

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 the installation.

NOTE: Applied coating should be protected from moisture during application and during the curing period. Exposure to moisture during this time can cause surface and colour variations.
