RSL Resudeck ST (formerly Resudeck) is designed to combat wet environments, whilst offering anti-slip aggregates and light to medium chemical resistance. It can dry overnight in warm temperatures ready for footfall after just 24 hours.
It offers adhesion to asphalt and bituminous surfaces without even needing a primer. It comes in a variety of colours that cure to a gloss finish, and can be used in conjunction with zinc-based primers, such as Resuprime ZP, when treating metal surfaces.
Recommended Uses
- Basement car parks exposed to water
- Vehicle decks
- Food areas - notably bakeries
- Plant rooms
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/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 using Resuscreed PA or Resuscreed 45.
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.
Where Resudeck ST 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 primer on the dry substrates only with less than 75% ERH reading.
Resuprime ZP 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.
The number of coats to be applied is chosen in accordance with the following table.
ERH% Required Coating Thickness
75-85 - 1 coat of Resuprime MVT at 200 microns per coat
85-92 - 2 coats of Resuprime MVT at 200 microns per coat
92-97 - 3 coats of Resuprime MVT at 200 microns per coat
For Further information please refer to recommended individual product data sheets.
Application
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 5°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.
Pre-mix the coloured 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 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 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. Coverage rates may vary depending on profile and porosity of the substrate.
