- Remove burrs caused by field cutting of ends or
handling damage and smooth out the edge of
the lining if rough.
- Remove all traces of oil, grease, asphalt, dust,
dirt, etc.
- 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 lined area before patching.
Be sure to overlap at least 1" of lining in the
area to be repaired.
- With the area to be sealed or repaired absolutely
clean and suitably roughened, apply a coat of
Protecto Joint Compound using the following
procedure:
- Mixing Procedure - The repair kit for
Protecto 401 contains two small cans of
Protecto Joint Compound. Protecto Joint
Compound is a two component epoxy and
the contents of the small container shall be
mixed with the contents of the large
container. If less than the full contents of
each can is to be mixed, the material may
be mixed using the mixing ratio printed on
the labels. After Part B is added to Part A,
the mixture shall be thoroughly agitated.
All activated material must be used within
one hour of mixing.
- 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.
Practices conducive to a good coating are
contained in the technical data sheet for
Protecto Joint Compound.
- 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.
