Hide glue will not react with a surface coating, either under or over
it, but it is wise to remove all excess.
What are the basics of hammer veneering?
Hammer veneering is the quickest way to veneer a substrate. Using hot
hide glue, both surfaces are brushed (or rollered) with glue and
placed together. The top surface is also coated with glue to act as a
lubricant. The "hammer" is then pushed across the surface from the
center to force out the excess glue. The glue will begin to cool and
gel immediately and hold the veneer in place. If the surface is
large, then make sure the surfaces are warm and having a heat source,
(heat lamp, etc) will keep the working time longer. It is not
necessary to buy a commercial veneer hammer, a block of wood with a
smooth edge will work.
Can you use a crock pot for a glue pot?
Yes, the important thing is constant heat at 140 degrees. A $5 baby
bottle warmer works too.
