Technique for repairing crackle lacquer of historical building wood product

Abstract

The invention relates to repair technology, in particular to technology for repairing historical building woodwork, and in particular relates to technology for repairing crack lacquer of the historical building woodwork. The technology for repairing the crack lacquer of the historical building woodwork is characterized by comprising the following steps: firstly, spraying or coating a layer of water-based paint which is taken as a water-based base on positions required to be repaired of the historical building woodwork; secondly, spraying or coating a layer of liquid arabia gum or dextrin on the water-based base, and drying the water-based base in the atmosphere without moisture to form an arabia gum or dextrin layer; thirdly, spraying or coating a layer of water-based paint on the arabia gum or dextrin layer; fourthly, drying the arabia gum or dextrin layer in the air; fifthly, using water to wipe positions required to be made antique, making moisture impregnated into the lower side of the water-based paint layer, and wiping off dried water-based paint fragments; and sixthly, spraying or coating at least one layer of water-based paint again. The technology solves the problem that the prior crack lacquer painting made by arabia gum is not exquisite enough.

[0001] The invention relates to a repairing process, in particular to a repairing process of historical building wood products, in particular to a repairing process of crack paint on historical building wood products. Background technique

[0002] The restoration of historical buildings and other cultural relics now emphasizes "repairing the old as old", especially the restored parts should be consistent with the unrestored parts next to them, so as not to give people a feeling of "patching". When repairing lacquered products, the biggest problem encountered is how to make the repaired parts have the same cracks as the unrepaired parts next to them.

[0003] The current method of cracking the paint surface is the crack cracking process using varnish. This process involves brushing a layer of brittle water-based varnish over a hard, flexible oil-based coating before it has completely dried; the oil-based coating dries not by releasing solvents, but by absorbi...
