PROCEDURES FOR REPAIRING FIELD DAMAGED AREAS AND COATING CUT ENDS OF CERAMAPURE™ PL90 CERAMIC EPOXY LINED PIPE AND FITTINGS

1.    Remove burrs caused by field cutting of ends or handling damage and smooth out the edge of the lining if rough.

2.    Remove all traces of oil, grease, asphalt, dust, dirt, chalking, etc.

3.    Remove any damaged lining caused by field cutting operations or handling, and clean any exposed metal by sanding or scraping, sandblasting or power tool cleaning roughening is also acceptable. It is recommended that any loose lining be removed by chiseling, cutting, or scraping into well-adhered coated area before patching. Be sure to roughen and overlap at least 1″ of lining in the area to be repaired.

4.    With the area to be sealed or repaired cleaned and suitably roughened, apply a coat of Ceramapure™PL90 Ceramic Epoxy using the following procedure:

5.     It is important to coat the entire freshly cut exposed metal surface of the cut pipe end. To ensure proper sealing, overlap at least one inch of the lining with this repair material.

Mixing Procedure

Ceramapure™PL90 Ceramic Epoxy is a two-component epoxy consisting of two cans labeled Part A Base and Part B Activator. Add the contents of Part B Activator into the contents of Part A Base. Immediately mix thoroughly. Mixed material must be used within one hour of mixing at 80°F decreasing with higher temperature. For smaller quantities, mix components at a 1:1 blend ratio.

Application of Material – After the material has been thoroughly mixed, it can be applied to the prepared surface by brush. Brushing is usually best due to the fact that the areas to be repaired are usually small .No Repair shall take place when the substrate or ambient temperature is below 40° F.  The surface also must be dry and dust free.  Practices conducive to a good lining are contained in the technical data sheet for Ceramapure™PL 90 Ceramic Epoxy.
