Refinishing The Piano Case - PianoLac
By Jon Page

PianoLac dries tough but not brittle.  It will not imprint (pads,
dollies).  As far as the 'feel' of it goes; it has a softer, warmer
touch because it is a water based acrylic but is tougher and easier
to repair than lacquer.  I've used PianoLac to repair scratches in
polyester, lacquer and PianoLac.

A grand refinished with PianoLac (PL) last year received a good gouge
on the treble side.  I simply laid in some PL with an artist's brush
(repeatedly) and sanded with a hard block and fine paper, then Scotch
Brite and wax; it disappeared.  This material has all the properties
a refinisher desires because it was developed by a refinisher.

Fish eyes are nonexistent with this product.  Surface contaminates
may be another consideration but the PianoLac Sanding Sealer/Stain
Blocker tackles many of those concerns.

PianoLac can be sprayed with any gun, it can even be brushed on.
(Brushable version is special request).  It levels out beautifully.
Arthur tells me that the PL Rub-Effect Clear flows out so well that it
doesn't need rubbing out.  I will be using that to make a satin finish
on black for scrolled legs, I don't want to rub those out.  HVLP has
the better transfer rate for spray equipment, Binks conversion gun
(PSI to HVLP) is relatively inexpensive.

I have only needed to remove PianoLac from a surface one time, that
I scraped.  I have removed other water based finishes and they _are_
harder than lacquer to remove.  I rarely use chemical stripper because
I prefer to scrape; it's faster and cleaner.  I would use a liquid
stripper on complex surfaces.

PianoLac Sanding Sealer is far superior to lacquer sealers.  The sealer
and top coat have a better build rate, sands easily and rubs out to a
perfect finish.  I hate refinishing; if it were not for the ease of use
of PianoLac, I would not be considering it.

Last year I sent a grand to a refinisher because I didn't have the room
or ambition at the time.  It came back in a dreadful condition.  The
only portion of the piano I did not have to sand, respray and rub out
was the side of the case.  I guess this shop (very reputable) does not
want my business.  Had they used PianoLac I could have probably gotten
away with a better rub-out technique instead of having to fill pores as
well.  The black PL matches the black lacquer, even in direct sunlight.
I've sprayed and buffed the vertical supports on a Yamaha lyre and PL
matched the black polyester.

My wife, who hates the smell of lacquer (I know -- hard to believe)
is unaffected when walking into the area, even while spraying.

Order the sample pack, use it for touch-ups.  You'll soon realize
the benefits of this material.  Those numbers again: 845-855-0996

Can you tell that I really like this material?
