Resins may crystallize in cool temperatures causing a white waxy substance to form on the bottom of the can. This condition does not in any way alter or inhibit the effectiveness of your epoxy. Dissolve by warming with a heat gun or in a double boiler and mix gently until the material is reconstituted. Allow epoxy to regain normal room temperature before using. Protect affected areas for one full day using black plastic wrapped or tented over work to keep materials warm and dry until epoxy has set.
Temperature is the determining factor.
Heat will cause epoxy to cure faster. Consolidant needn't be completely cured before application of ConServ 200 patch because the ingredients are compatible. Apply material using a trowel, putty knife, caulk tube or by casting in place. DO NOT allow epoxy to freeze. Tools may be cleaned before full curing using hot soapy water or acetone.
