Default Ultrastar issues - some thoughts

I assume this is a new finish since it is trim. Did you sand it to
prep yourself?


Yeah.

Two passes through a Performax, last sanding with a Mirka-loaded ROS,
scuffed with Mirka PSA on a PC finish sander. This is all the s4s
section of built-up base and door trim. At least it isn't a crazy
profile or doors!


Who handled the trim? Was it delivered or are you on site?


I picked it up at my usual hardwood supplier.


the old fashioned way. Strip/sand/start over. I do know that MLC has
a fisheye reducer for this product, FWIW.


I have it and used it on the re-do.

Is it possible that the MLC material was not up to snuff? Could it
have been old, or previously opened and improperly resealed?


That is a possibility. The can was originally cracked in July (I date
my lids), but I used the same can for the first coat.

As a
tandem thought, does your supplier handle the material properly on his
end? Sitting in a really hot/cold warehouse for a length of time will
change almost any of this stuff.


The warehouse is climate controlled and pretty much 65-70F year round.
It's the basement of a busy paint store.


Generally for me, getting rid of the fisheyes means strip off the
finish in the affected areas and clean well. I seal with a 1/2 lb
spray coat of shellac put on with the 1mm aircap and start over again.


The weird part is that this stuff is coated as follows: stain / Seal
Coat / US / US. Coat #1 of US was excellent, coat #2 went awry.
Next stop... Quick Kleen.


You might think about calling them anyway. As a new cutomer they will
send you a quart free as well as a book of their products. At least
you could give it a whirl and see what you think. Always good to have
another tool in the belt.


I ordered a quart each of the gloss, satin, and semi-gloss fast-dry
poly, and some flow enhancer and fisheye killer to play around with.

Last night, I sanded and re-Seal Coated everything. This afternoon,
I'll SW Fast-Dry, as I'm running low on time. I've never had that
stuff fish-eye on anything, so maybe I can move on. I have 22 sheets
of sub-floor to install this morning in a barn conversion.

The idea of grabbing a fresh supply of US is a good one. I also have
some Semi-Gloss and Gloss on hand, along with the suspect Dull US. I
can try the different cans on test panels, under identical
troubleshooting conditions.


I really like using non-flammable, way less stinky, materials, so
here's to sorting it out.

Thanks for the tips.
