Xymertol Rapid Cold Cure Primer is an unpigmented, solvent free, two part polyurethane/ urea concrete primer that in cold conditions is ready to re-coat in 20 minutes down to a temperature 0°c, thanks to the use of Cold Cure Technology.

Xymertol Rapid Cold Cure Primer has a long pot life but when applied is quickly cured by the action of atmospheric moisture. It will quickly develop a bond to concrete that is stronger than the concrete itself.

Xymertol Rapid Cold Cure Primer  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.

This product is ideal for cold storage facilities, for a primer for normal room temperature please see Xymertol Rapid Prime.

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: 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.
