RSL Resuprime OT (formerly known as R.S. Oil Tolerant Primer) is a two-component epoxy resin floor membrane that combats any residual oil that has escaped into a concrete floor. It ensures that no oil will affect a top finish.
RSL Resuprime OT (formerly known as R.S. Oil Tolerant Primer) allows finishes to be applied seamlessly onto concrete that have previously fallen foul of engineering oils.
It can be used on substrates with hygrometer readings of up to 85% RH, and your floor or screed should be at least 50mm thick if unbonded. It must have the required mechanical strength to produce an even coating.
It is essential that all surface and gross contamination is removed by cleaning with R.S. Oil Remover and R.S. Industrial Floor Cleaner.
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/mm sq. 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 with 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 intercoat adhesion and suitability, as it may not be compatible with existing floor coating.
RSL Resuprime OT can also be applied to existing coatings and to other cementitious screeds which should be clean and sound with an appropriate mechanical key for adhesion.
RSL Resuprime OT is suitable on concrete with Relative Humidity readings up to 85% ERH. Where the relative humidity of a substrate exceeds 85% 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:
ERH% Required Coating Thickness
85-92 2coats of Resuprime MVT at 200 microns per coat
92-97 3coats of Resuprime MVT at 200 microns per coat
For Further information please refer to recommended individual product data sheets.
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: Pre-mix the base component to a uniform consistency then mix the entire contents of the base with the hardener. If a separate mixing bucket is being used for mixing 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 have fully combined.
The mixed unit should be applied immediately by squeegee, roller or brush with a consistent procedure. Floor areas should be cross-rolled to ensure even application and to minimise roller marks.
