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.
