Self Levelling Acid Resistant Screed
CPR 606 Self Levelling Acid Resistant Screed is a rapid-curing, resin rich, three pack slurry, having exceptional resistance to aggressive acids, solvents and alcohols (e.g. 96-99% Sulphuric Acid, Methyl Ethyl Ketone, and Methanol).
CPR 606 Self Levelling Acid Resistant Screed is typically applied at thicknesses of 2-6mm depending upon service conditions and performance requirements. A slip resistant finish may be achieved by broadcasting an appropriate aggregate into the slurry. This screed may be applied directly to suitably prepared concrete or steel surfaces.
- Solvent free
- Outstanding chemical resistance
- Excellent adhesion to concrete and steel
- Tough, durable and abrasion resistant
- Very rapid cure, even at low temperatures
- Slip resistant options
Direction for Use
Surface Preparation Concrete
- Concrete shall be a minimum of 21 days old and/or the residual moisture content shall be below 6%. Ensure that the concrete is clean and free from dust, laitance, grease, oil, curing compound and existing paint finishes etc.
- Blow holes and defective concrete shall be made good using a proprietary repair compound.
- Suitable mechanical treatment such as vacuum grit blasting is the preferred treatment prior to application as this ensures a mechanical ‘key’ for the slurry.
Surface Preparation Steel
- Steel surfaces shall be shot blasted or grit blasted to a nominal Sa 2.5 Swedish standard to provide a coarse blast profile.
- All dust and grease shall be removed prior to coating application.
- Not normally necessary on concrete substrates, although a coat of CPR 414 – Acid Resistant Epoxy Concrete Primer may be applied to especially absorbent surfaces.
- No primer is required for mechanically prepared steel substrates.
- The material is supplied as a three pack material consisting of the resin BASE component, the CURING AGENT component, and the FILLER component.
- The contents of the Curing Agent container should be emptied into the Base container, and the two liquids mixed thoroughly, preferably by mechanical means.
- The mixed Base & Curing Agent components should then be poured into a mixing vessel e.g. Creteangle type, and the Filler added whilst stirring, mixing thoroughly for 2-3 minutes..
- The mixed slurry shall be poured onto the prepared surface and spread out with a serrated trowel or steel float to a thickness of 2-6mm, as required.
- The material may be spike rollered but this will not be required if an aggregate broadcast is to be made.
- When a slip/skid resistant finish is required, an appropriate aggregate (such as Dynagrip, Calcined Bauxite, Flint, or Quartz) should be broadcast at a nominal rate of 6-15kg/m².
- The following day the excess aggregate shall be swept from the floor.
- Where a Sealer coat is required over an aggregate profiled surface, mix and apply a coat of CPR 602 – Acid Resistant Epoxy Paint at a nominal rate of 0.3-0.5kg/m².
- Allow to cure for a minimum of 8 hours @ 20°C prior to light foot traffic access and 24 hours @ 20° prior to vehicular trafficking.
- Allow a minimum of 5 days cure @ 20°C for optimum chemical resistance.
- NOTE: Lower ambient and substrate temperatures will result in extended curing times.
- Clean equipment with CPR 200 – Tool Clean Solvent prior to curing of the coating.
- Do not apply to wet or uncured concrete surfaces.
- Do not apply at temperatures of 2°C or less.
- Discoloration/bleaching of the coating can occur on contact with certain aggressive chemicals.
- Discoloration is purely a surface effect that does not detract from the efficacy of the coating in service
- A 25kg pack is sufficient to cover an area of 6.9m² @ 2mm thickness, or 4.6m² @ 3mm thickness.
- Pot life @ 20°C: 30 Minutes
- Pot life @ 10°C: 60 Minutes
- Colours: CPRL standard Grey, Red (BS4800 or RAL colours on request)
- Walk on time @ 20°C: 8 Hours
- Full traffic time @ 20°C: 24 Hours
- Temperature range during application: 2°C – 35°C
- Temperature range during service: -10°C – 70°C
- Compressive Strength: 75 MPa
- Excellent Chemical Resistance
