This kit has been specially designed to complete Clock and Barometer, Dial restoration. Please note:
This cellulose based lacquer is fine to use on clock dials as long as the first coat is a very quick, light coat. It can then be applied heavier/thicker after the first coat has dried.
The lacquer should only be applied thinly to engraved dials.
Dial wax will melt and run if too much lacquer is used.
A soft cotton cloth or cotton wool pad can be used; a quick swipe is the usual method then leave to dry before touching or attempting to add more lacquer.
- Cleanliness is of paramount importance when silvering and almost all problems encountered are due to finger marks on the metal between cleaning and applying the powder. Silvering powder acts by chemical reaction with the metal, and if this cannot take place evenly, an uneven colouring occurs. This powder will not work on plated or lacquered dials. It will not work on aluminium. Use only on clean brass or copper Dials.
- We find that on some certain dials, they hold a lot more moisture than others. This can affect the silvering process overnight, making the brass patchy or loosing the silver effect on your dial. To resolve this, after the finishing powder process, dry quickly the front and back without spreading any grease or dirt from the back, so use different cloths. Then warm the dial quickly to ensure thorough dryness, either by hairdryer or well above a naked flame. This will ensure the cracks and stress fractures are totally dry. This will usually resolve the problem.
