I live in a condo. The buildings in my development all have wood siding and
the association has always used a "solid color stain" which, to me, looks
the same as paint. Over time, older stain peels off the way paint peels
off.

They are in the process of re-staining a few of the buildings. It appears
(without my watching their every move) that they first using a pressure
washer to remove any peeling stain and then as much as week later, the are
applying (spraying) a brand new coat of stain over the siding which still
contains older stain (since...my understanding is that the pressure washing
does not remove all the old stain...only what was on the verge of peeling)
They are using sprayers to apply the new coat of stain.

Is the above the correct procedure for re-staining, or are they supposed to
strip off ALL of the old stain before applying new stain?

The reason I'm asking is there have been problems with peeling stain on a
couple of RECENTLY re-stained buildings.

Thanks.

Pretty tough to determine what is right without knowing the products
they are using (old and the new applications)...can you find out and
post more info?

If some newly stained surfaces are peeling, be sure to let your condo
board know - phone call followed by certified letter. Trust me )

I have seen acryllic paint peel off previously transparent stained wood,
which was probably an oil stain based on building quality and age.
Pressure washing is pretty standard for concrete block/stucco and for
wood with loose finish. Takes greater care with wood to prevent damage,
and takes time for adequate drying prior to priming/painting.

Stain wont peel if done right, most likely it was stained in the sun or
on a hot surface, or just to hot out. Read a can label and call any
manufacturer, surface temp is critical. If it is peeling washing is one
step scraping is another. For the paint they are using call the store
or company and get out the representative, we cant see it, but this is
common to have done. What brand stain is being used.
