Applying Cold Microcrystalline Wax To Bronze



APPLYING COLD MICROCRYSTALLINE WAX TO BRONZE


PART 1---GENERAL

1.01 SUMMARY

    A.   This procedure includes guidance on applying a hard
         microcrystalline wax to bronze.  The bronze may be either
         architectural components or sculpture.  

    B.   This wax acts as a barrier or sacrificial coating and
         protects the metal and any underlying coatings such as
         hot wax coatings, paint or protective lacquers such as
         Incralac.

    C.   Cold waxing is usually performed as part of a semi-annual
         washing and renewal of the barrier or sacrificial
         coating.  It is also done following any application of
         hot wax (see 05010-04-P "Applying Hot Wax to Outdoor
         Bronze") or Incralac.

    D.   For general information on the characteristics, uses and
         problems associated with bronze, see 05010-03-S.
