Epoxy Concrete Repair Quartz ( Incl 302 Primer)
Epoxy based Quartz reinforced concrete repair screed
356 is a high performance mortar designed for use as a heavy duty repair system for concrete and mineral surfaces.
356 is based on a blend of solvent free epoxy resins and polyamino amine adducts reinforced with a special blend of silica quartz minerals and inorganic fillers which have been specially selected to provide optimum application and performance properties together with a high level of adhesion, abrasion, impact and chemical resistance.
356 is a unique repair system, easy to apply by trowel or float with no shrinkage or volume change during cure and is ideal for the repair of damaged concrete, sills, lintels, steps, ramps, walkways and loading bays..
All dirt and loose friable material should be removed, and the surface cut back to a sound edge. Any exposed re-bars must be fully exposed and treated with a ProTXcoat 302 Solvent free primer.
Abrasion of surfaces will cause dusting and therefore all loose dust should be vacuumed clear before the application commences.
Whilst 350 can be used without a primer, on certain very porous surfaces a coat of the mixed 350 resins should be applied to prime/ seal the surface.
Two parts of base resin should be mixed with one part of activator by volume and the mixed system brushed into the prepared surface.
350 is a three component material which must be mixed together prior to use.
When mixing the complete unite aggregate component should be removed from the outer container, which is then used as the mixing container. The base and activator containers should be emptied into the mixing container and mixed until homogeneous. The aggregate should now be added and thoroughly mixed into the base resins to ensure complete wetting out.
The mixed 350 should be applied by float or trowel to the prepared surface with the material being pressed firmly onto the surface then finished by float to give a smooth surface.
When applied at 4mm 350 will provide a coverage rate of 0.5 m2 per 5 kg unit.
When applied at 6mm 350 will provide a coverage rate of 0.3 m2 per 5 kg unit.
All equipment must be cleaned IMMEDIATELY after use with MEK Solvent Cleaner.
NOTE: The minimum temperature of application is 5oC (50oF).
