- Directions
SURFACE PREPARATION: Concrete to be repaired should be a minimum of twenty-eight days old. The area to be repaired should be thoroughly cleaned. Remove any weak, unsound or cracked concrete. All oil, grease, dirt, curing or sealing compounds and other contaminants that might interfere with bond must be removed. Surface area to be repaired should be shot or sand blasted, scabbled or scarified to obtain a 1/8 inch surface profile. Remove any dust or residue using a vacuum or oil-free compressed air.
PRIMING: Prime surfaces to be repaired with Duraguard 100 at a rate of 200 square feet per gallon. Follow the mixing and application directions on Duraguard 100 technical data sheet. Do not allow primer to dry prior to mortar application.
MIXING: Mechanical blending, using a heavy duty, high RPM drill and mixing paddle or a paddle type mortar mixer, is the recommended method. Proper mixing is critical to a successful project.
Mix all of the Part A Resin and Part B Hardener in the pail provided for two minutes. Add the Part C Aggregate and mix until aggregate is well coated and uniform in appearance. Do not mix more material than can be placed within the 20 minute pot life.APPLICATION: Spread mixed epoxy mortar into area to be repaired. Carefully compact material, taking care to fill all voids and maintaining full contact with substrate. In large areas use a concrete come-along or screed box to spread the mixed material evenly to grade. Mortar should be trowel finished by hand or machine to produce a smooth, nonporous surface.
CURING: DuraPatch EPX is self-curing. For improved chemical resistance or appearance, DuraPatch EPX may be coated with Duraguard 310 CRU, chemical resistant urethane, in clear or colors.
- Cleanup
Before the mixed material sets, clean tools and equipment with xylene or xylol.
