The bubble problem in the veneer
Bubble veneer, lifting veneer, or loose veneer is the problem that is often encountered in the veneering process. It is caused by the wood veneer that does not
stick properly to its core. The Bubble veneer can appear very much and become
big problem to the veneer surface. The veneer bubble will be more visible if the wood
veneer is finished. The bubble part will be cut off when it is sanded and seem as white wood. The bubble
is more obvious when the veneer is laid at the flat and big panel especially when
the high gloss finish is generated. But even for the low sheen finished, the
bubble is still be problem,
Although the bubble is caused by improper gluing process, but the bubble problem is often found in the finishing process. The bubble veneer
is appearing when the veneer surface has been coated with finishing materials.
Sometimes bubble may be visible on the stain application, but often the bubble
appears at the sealer application. And in this state the process of repairing will always damage the existing finishing layer. The action to fix
the bubble must be followed by the process of washing off the finishing layer and
the re finishing process. It can be considered as wasting of finishing material and
time. Then it will be much better if we can
do the right veneering process to minimize the bubble problem.
