THE REAL CAUSE^OF PINHOLES
Thin Filler and Careless Brushing Usually Are
Responsible for This Defect
Discussing the cause of pinholes in veneered
work, a writer in Veneers says:
"I have never seen veneer that could not be
filled without pinholes where the filler was
properly used. The consistency of filler should
be according to the porous nature of the wood
on which it is to be used; a heavier filler being
used on the more porous woods. Pinholes are
usually caused by one of two things, i. e., a
filler that is too thin for the wood on which
it is used, or a lack of care in properly brushing
it into the pores. To make a correct job the
filler must be worked into the pores while it
is yet in the liquid state, then allowed to dry
and then the surplus cleaned off. If the filler
is put on without any effort being made to
work it into the pores until the cleaning off
process begins failure will result if the wood
is of a very porous nature, because at this stage
the particles of filler are too dry to bind them-
selves together in the pores. The cleaning-off
process should be such as will disturb the filler
in the pores as little as possible, otherwise
as much will be worked out as is worked into
them.
"Any pore, or any hole in the glue that is
in the pore, that is too small or shallow to
retain filler, properly applied, during the clean-
ing-off process, will never show up as a pinhole
after the goods are finished, because the shellac
and varnish will then fill it up. Pinholes can
result only where the original hole is too deep
for the varnish to reach the bottom and fill up.
If a pore is very deep it is quite difficult to
work the air out that the varnish may reach
the bottom. It is much more difficult to work

varnish, than it is to work filler, to the bottom
of the pore, owing to the elastic nature of the
former. Moreover, it is not a part of the var-
nisher's business to so work his varnish that it
will reach the bottom of deep pores. But if a
pore is so deep that the varnish will not reach
the bottom in the ordinary process of applica-
tion, it is certainly deep enough for the filler
to get hold if properly applied.
"Another prolific cause of pinholes is the
presence of too much oil in the filler. When
filler is properly prepared in the paste form
it contains sufficient oil to bind the pigment
together, which is all that is required, and more
should not be added, as it will make the filler
work too sticky, and make it difficult to clean
off without pulling it out of the pores. it
should be reduced only with benzine or naphtha
to give best results.
"What I have here said it not mere theory,
but it is the result of scores of experiments
right along this line, extending over a period
of twenty-five years. These experiments have
been conducted with all kinds of filler and all
classes of veneer; and I can assure the finisher
who has given up hope of ever being able to
overcome pinholes in certain kinds of veneer,
that if he will follow instructions here given,
his troubles in this respect will be forever gone."
