Sherwin-Williams Floorcoating Resuprime OT

Robust epoxy primer

Resuprime OT is a two-pack epoxy primer flooring membrane that is tolerant of residual oil contamination in concrete floors.

Formerly known as 'RS Oil Tolerant Primer', Resuprime OT can protect the floor by ensuring that the oil contaminates will not come through and affect top finishes.

Easily applied by brush, roller or trowel edge as an industrial resin flooring.

Ideal for substrates with oil contamination, concrete substrates with no damp proof membrane, factory floors, cementitious underlayments and automotive workshops

Recoating can take place after 6-8 hours or once the surface has lost tackiness. For light traffic areas wait 18-24 hours; full traffic leave at least 48-72 hours and for a full chemical cure wait seven days.

Theoretical coverage rate is 23 m² @ 200 µm for 5kg.

Full product data sheets and safety data sheets are available on request.

Product Benefits

  • Easy application
  • Application onto substrates with engineering oil contamination
  • Application onto substrates with Hygrometer readings up to ERH 85%
  • Solvent-free
  • Low odour
  • Excellent adhesion
  • Suitable for all Sherwin systems as subsequent floor finish

Surface Preparation

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.

For 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 must have all coatings and loose floor paints removed by mechanical preparation 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 Resuprime OT is applied to masonry/concrete surfaces, care must be taken to ensure that surface preparation is thorough but does not disfigure the surface.

Contaminated substrates require thorough cleaning prior to surface preparation and priming.

R.S. Oil Pretreatment can be used to help remove any oil contamination.

This must then be thoroughly washed off using R.S. Industrial Floor Cleaner.

Please refer to the product datasheets for information on proper use of these.


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.

Using a slow speed electric mixer, mix 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.


Volume Solids: ~100%
VOC: 84 g/l calculated per full mixed
Colours: Clear
Finish: Smooth gloss
Flash Point: N/A
Cleanser/Thinner: N/A
Pack Size: 5 kg and 15 kg
Pack Weights: 3.33 kg base/1.67 kg hardener (5 kg); 9.99 kg base/5.01 kg hardener (15 kg)
Mixing Ratio: 2 parts base to 1 part hardener by weight only
Mixed Density: Approximately 1.08 g/cm3
Shelf Life: 36 months (Base and Hardener)
Storage: Keep out of direct sunlight. Store in a dry place, between 15°C - 30°C
Application Methods: Brush, roller or squeegee
Application at 20°C
Recoating Intervals: 6-8 hours or once surface has lost tackiness. Light Traffic: 18 – 24 hours; Full Traffic: 48 – 72 hours; Full Chemical Cure 7 days
Pot Life: 25 – 30 minutes from mixing, based on 5kg pack size. The pot life may be shorter for larger pack sizes if the paint is not used within the pot life limit.
Note: All mixed paint must be used within the pot life time limit, if the paint is left in the container after mixing and not used, it may release hazardous fumes due to exothermic reaction.
Coverage Rate: (Theoretical) 5 kg will cover 23 m² @ 200µm. Coverage rate is calculated based on a sealed and smooth surface and may vary based on the substrate roughness and other conditions.
System Thickness: (Recommended) 200 – 250µm. The suggested thickness range is calculated based on average volume solid as a general recommendation for the specified condition and for each application may vary
