the years Shellac has had many uses, it was used to insulate early
electrical wiring, the first gramophone records were made of it and
for centuries it has been known as the king of finishes.

also available in liquid form and is usually called French Polish or white polish
if made from white shellac. These liquids
only have a relatively short shelf life and start to
deteriorate after about 12 months. Unfortunately the
polish may have been in the shop for a year or more
before you buy it, this means that it may well be bordering on stale
before you come to use it.

either 500ml or 1 litre of Methylated Spirits depending

thoroughly dissolved, (stir occasionally) finally strain
the liquid through a stocking back into your jar.

removes any foreign material)

on to new timber in a series of coats to give a bright
finish. It can be applied with a pad or rubber as in French polishing. It can be thinned and used as a a
sanding sealer or a base for applying a wax polish.

not experienced at using French Polish you would be well
advised to undertake a class in polishing or at least
obtain information from a good book on polishing or from
someone who is experienced in using the product.

use for some applications it is not advisable that the

abrasive 400 grit then 600 grit, use water with a little
dish detergent in it to sand with. After sanding dry the

timber. Always sand with the grain.
French Polished Finish
finish is applied with a rubber (a pad made by wrapping
linen or cotton sheeting around a pear shaped filling of
cotton wadding) This form of polishing is best done after
formal instruction. It is used for the finest furniture.
Polish can also be sprayed on to a surface by means of
conventional or airless spray equipment. This is usually
used as a base for other finishes.
Coloured French Polish
polish can be easily coloured by the addition of
universal tints. (readily available from any paint shop)
coloured polish is usually applied by means of a brush or
spraying. If used over a white base it can give some
startling effects especially if used for scumbling or
with a stippling brush or sponged.

as a Grain filler
Decant off about 20mm
of French Polish into a clean glass jar, add an equal amount of
methylated spirits then add about half a teaspoon of our
to the liquid and mix in well. This can be painted onto the surface of
an open grained timber as a sanding-sealer/grain-filler. When it dries
it is easily sanded leaving a silky smooth base upon which to continue
your polishing. If the timber colour is muddied by the talc mix add
extra French Polish and meths.

to charge a rubber during polishing. Each bottle is clearly labelled
with a Date of Manufacture and a Best Before date. Very important
