Grex Dwellings Item 12: The House Painting Item
Entered by n8nxf on Thu Sep 18 18:45:59 UTC 1997:

I'm looking for a good painter to paint the outside of my parents house.
Their house is a difficult case as it was sided with redwood and then
was painted with a mixture of linseed oil and shellac several times over
a 30 year period.  About 4 years ago that was covered with a standard,
pigmented, latex house paint.  The linseed oil mixture did a great job
of preserving the redwood (As though it needed it.) but now forms 
blisters under the paint when the hot summer sun hits it.  The redwood
is too soft to pressure wash (One bozo already tried that and only
proved me right.) and I am at a bit of a loss as how to approach preparing
and painting this house.  Any thoughts?

Go to Andersons and ask for advise.

would alkyd paint work better?  It might be more compatible with the linseed
oil.  Try calling any of the paint companies for advice.  Kurfees has someone
in the technical dept. who is really interested in paint chemistry.  I think
Kurfees is sold at Paint N Stuff 996-5700 and you can call them for the number
(might be an 800 number).  
Have you tried a light sanding?  Is it really the linseed oil making bubbles,
or the latex paint which is bubbling because it does not stick?

Getting the paint to stick is not a problem.  The blisters I mentioned
occur somewhere between the redwood and several layers of shellac /
linseed oil applications.
 
Late this summer, a painter showed up at my neighbors house because he
thought their house could use a coat f paint.  They cautiously gave him
the job and he did a very nice job, showed up when he said he would, etc.
Having seen him work and the quality of his work, I asked him if he would
be interested in doing my parents house.  He took the job.  I suspect the
blistering will continue but he left my folks with paint so they could
touch it up and said he would come by in the spring to take care of any
problems.  It is the nicest paint job the house has had in years and my
parents were very happy with him too.
