FWIW Paint
This has been an interesting couple of days. I am finishing my Bobcat and
yesterday evening I was facing a paint disaster. Blisters. Zillions of them
all over the deck of my newly painted Bobcat. A call to the Interlux
service line and a return call from the local International Paint rep gave
me the following information. Besides all the usual caveats about removing
the amine blush from epoxy coatings I have been given the reasons behind
some of the instructions on the can. I am using Interlux Brightside which
has served me well in the past. First the instructions say to sand the
Brightside primer until it is translucent. No reason given on the can. I am
told that the primer contains microballons which I was aware of however I
was not aware that microballoons take in water. The point of sanding to
translucency is that it is necessary to remove almost all of the primer
leaving only that which fairs the surface. The second thing I learned was
that Brightside Polyurathane requires anywhere up to 2 weeks or more to
fully cure and that it is vulnerable during this period. In my case my
Bobcat was moved out of the garage several days after being painted-this a
week or so ago. The day before yesterday we had a gullywasher of a storm
which left standing water on the deck. By evening, where there was standing
water, there were pinhead sized blisters. This morning there were zillions
more. By three oclock this afternoon after baking in the hot sun they were
almost gone. There are only few left now.
Maybe I'll refinish the deck this winter but then again maybe a full cure
will prevent the re-formation of the blisters.
