and gloves, and use in a well-ventilated area. Avoid contact with skin, eyes, and
clothes, and DO NOT breath vapors. DO NOT use near open flame or excessive heat.
If you become dizzy while using drycleaning solvent, Immediately get fresh air and
medical help. If solvent contacts your eyes, wash them immediately and get medical
help. Failure to follow this warning can result in injury or death.
Remove dust and oil from repair area and clean with dry cleaning solvent and lint-free rag.
NOTE
If damaged area is near an opening in tank, apply a backing plate with masking tape and
release film, rather than wire cloth.
If opening is less than one inch across at greatest point, wire screen is not required.
Cut and trim a piece of wire screen (3) 1/2 inch larger than opening.
Cut glass cloth patches (4) to size and shape. Cut first glass cloth patch (4) 1/2 inch larger than screen (3),
and cut each succeeding patch (4) 1/2 inch larger until sufficient glass cloth has been built up to make patched
area level with surrounding tank wall.
NOTE
Hardening will occur in the cup within one hour. Do not mix more than one cupful at
one time.
Cut top from resin envelope and hardener envelope. Squeeze contents into paper cup and mix thoroughly.
Using hardwood depressor, thoroughly saturate hole (1) area and screen (3) with epoxy cement, and apply
screen (3) over hole (1).
Remove 1/5 of cement from paper cup and place this into new paper cup. Add small amount of regenerated
silica to obtain puttylike consistency. Use the mixture to apply first two layers of glass cloth (4).
