[Woodcarver] mildew

[maricha]

hi peter thank you for your great answer.

this wonderful tree was cut down only three weeks ago.
the day after it was cut, with the chainsaw, i cut the figure i am 
sculpting, using the chainsaw, like a bandsaw to remove as much material as 
possible, yet retain the main part of the figure form. then i sealed all cut 
areas with pva, as i did not want too much moisture ozzing out too soon. 
then i covered it with insulating material used for the roof , which has 
worked for me in the past, hardly cracking the timber, but unfortunately we 
had a trades man, cleaning our patio where the sculpture to be stands, and 
the rain or water from the cleaning got into it, i presume.

i have worked on it a few times, but for the last two weeks have not been 
able to touch it, and the rain has poured, then extreme heat.... when i went 
to work on it yesterday, wow, my heart fell down to the rocks, when i saw 
these polka dots of mildew, but an expert told me the mildew is only on the 
pva... and i should not worry...

now the second problem i have is big black giant cocockroaches..  i do not 
want to use chemicals because it will make the timber toxic, which is really 
great timber for plates, as well as spoons etc. but most of all i do not 
want to make it toxic for myself when i am working. the second problem is 
....how to get rid of the black cockroaches....HA HAHA  one of my wonderful 
students, suggested that i ask my husband to get a mallet or be the official 
foot killer, non-toxic insecticide.

immediately it brought a wonderful caricature of a non-toxic matador.

thanks for your email, will give your method a go.

cheers
maricha
