Carbonamine Rapid Prime
Carbonamine Rapid Prime is an unpigmented, low solvent, two part polyurethane/ urea concrete primer that in most conditions is ready to re-coat in 40 minutes, thanks to the use of Advanced Cure Technology.
Carbonamine Rapid Prime has a long pot life but when applied is quickly cured by the action of atmospheric moisture. Xymertol Rapid Prime will quickly develop a bond to concrete that is stronger than the concrete itself.
Carbonamine Rapid Prime can be used for priming and sealing porosity in concrete, masonry and other non metallic substrates before coating with polyurea spray, polyurethane or epoxy coatings, mortars or screeds.
For a primer needed for cold storage facilities please see Carbonamine Rapid Cold Cure Prime.
Type: Two part moisture activated polyurea coating
Mix Ratio: See label on tin
Hardener: Xyanco 243
Resin Density: 1.06kg/litre
Coverage: 7-10 m2/litre, depending on surface texture and porosity
Minimum over-coating time: 40 minutes
Maximum over-coating time: 48 hours
Solvent: Thin with Xysol PU if necessary and for spraying
Colours: Clear
Pack Sizes: 1, 2.5, 5 and 10 litres
Shelf life and Storage: 6-12 months in original, unopened container. Store in cool and dry conditions
Preperation: Concrete substrates should preferably be diamond
ground or blasted but if this is not possible the surface must be clean and free of loose material, laitance, oil, grease etc.
Mixing: Add all of the hardener to the tin of resin and mix slowly for several minutes preferably using a flat mixing blade in a drill. Try not to mix air in with the resin as this will reduce pot life. If you require a smaller quantity or
are unable to use all of the material within its pot life, weigh out resin and hardener in the proportions specified on the label using digital scales.
Application: Can be applied by brush, roller or airless spray. A thin coat should be applied ensuring that the material is worked well into pin holes and imperfections so that 100% of the surface has been covered. Avoid leaving excess material to form thick areas as foaming may occur. On some porous substrates a second coat may be required to completely seal all porosity.
Over-coating: Carbonamine Rapid Prime can be overcoated with virtually all other types of coating as soon as it can be walked on which is 20-30 minutes in most conditions. Carbonamine Rapid Prime will chemically bond to epoxy, polyurethane and polyurea coatings provided they are applied before the Carbonamine Rapid Prime is fully cured. We recommend that Carbonamine Rapid Prime is over-coated within 48 hours.
Advantages
- Rapid: Can usually be over-coated in 40 minutes
- Amazing Adhesion: Quickly develops an exceptional bond to dry and slightly damp substrates
- Easy: Is easy to mix and apply
- Less Stress: Long pot life after mixing gives ample time for application
- Compatible: Can be over-coated with most other coatings including epoxy, polyurea, polyurethane, polyaspartic etc.
- Adaptable: Can be applied to ground or blasted concrete or old surfaces that are free from oil and other contamination
