[Woodcarver] mildew

[Tom Clarke]

Maricha,

     Don't know about carving wood but in basic woodworking one can
use
a VERY dilute bleach/water wash to curb mildew. Course, the wood gets
wet when you do that <g>. Not sure if the mildew is happening to the
PVA
or showing up at the end grain. In either case you'd want to apply the
mix
and let it sit for a while and then wash it off with more water. The
bleach 
might change the color of the wood. Anywho, after the wash put the
wood
in an elevated (so it isn't resting on the ground and air circulates
evenly)
spot with PLENTY of airflow.

hi folks, have started sculpting a large tree , Pittosporum ,
(Pittosporum undulatum Vent. Small hardwood common in wetter areas of
coastal new south wales and queensland australia. it is wonderful to
carve and am hoping to have a life size sculpture about .  we had to
cut the tree down as it was interferring with the pipes of the
bathroom and to my great joy it is a joy to carve.  After cutting the
wastage with the chain saw to get to the design, all ends were sealed
with PVA, and to my horror, mildew is appearing wherever i used the
blessed PVA.  at this stage it appears to be on the surface of the PVA
coating, as we have had real inclement weather of lots of rain, then
extreme heat.  any suggestions would be much appreciated so that this
beautiful tree can be saved from mildew.

THANK YOU IN ADVANCE.

CHEERS
