<div class="moz-cite-prefix">I have not had this experience because
I don't use Theatrical Paint for Architectural surfaces. Both of
my performance space floors are covered with tempered hardboard -
neither of them has this problem.<br>
<br>
There are two possibilities here - either your 'masonite' is
pretty shitty stuff, or the Rosco product just isn't up to the
job. <br>
<br>
I have instructions posted here:<br>

<br>
I am pretty specific bout the type of paint - for a reason.<br>

<p class="MsoNormal">Over the <span style="mso-no-proof:yes">summer,</span>
we
installed a new stage floor surface on our stage. We used
double-sided
tempered hardboard - aka as Masonite. Yes – I realize
Masonite is like a <span style="mso-no-proof:yes">brand name</span>
like Kleenex is to tissue. The
hardboard <span style="mso-no-proof:yes">was laid</span> over
the original
stage floor made out of maple tongue and groove boards.
Expansion gaps <span style="mso-no-proof:yes">were left</span>
in between each piece of Masonite and
fastened to the <span style="mso-no-proof:yes">ground</span>
with Senco 8x1 1/4
cement board screws. Before the floor was installed. <span
style="mso-no-proof:yes">We</span> painted all surfaces and
edges
with Rosco Tough Prime. I’ve used Tough Prime since it came
out and
never had a problem with it.<span style="mso-spacerun:yes"> <br>
</span></p>
<p class="MsoNormal"><span style="mso-spacerun:yes"><br>
</span></p>
<p class="MsoNormal">After the Masonite <span
style="mso-no-proof:yes">was
fastened</span> <span style="mso-no-proof:yes">to the
ground</span> we noticed
that the paint was coming off by rubbing our shoe against it.
We were
turning our foot on the edge of the sole and swiping the
floor. I'm not
talking just <span style="mso-no-proof:yes">a regular</span>
<span style="mso-no-proof:yes">scuff</span> from the rubber <span
style="mso-no-proof:
yes">sole;</span> I'm talking paint completely pulling off
down to raw
lumber. I contacted Jenny Knott at Rosco and explained our
situation. She
informed us that she <span style="mso-no-proof:yes">had</span>
seen instances
of this. She went on to explain how the processing of
tempered hardboard
has changed over the years. Apparently, the processing now
involves
linseed oil. And as we all know, oil and water-based products
do not <span style="mso-no-proof:yes">mix</span>. She advised
us to wash the raw Masonite and
apply more coats of paint. She also advised us to let the
floor cure for 48
hours. <br>
</p>
<p class="MsoNormal"><br>
</p>
<p class="MsoNormal">The other layer of this onion involves our
observation of
lighter colored Masonite. <span style="mso-no-proof:yes">I'm
used</span> to the
chocolate brown <span style="mso-no-proof:yes">Masonite.
Instead,</span> this Masonite
was blond in color. I contacted the lumber <span
style="mso-no-proof:yes">yard,</span>
and they said color <span style="mso-no-proof:yes">didn't
make a difference</span>.
The Masonite had a smooth finish on both sides, so I know <span
style="mso-no-proof:yes">it’s tempered</span>. We went to
another lumber
yard and picked up another batch of Masonite. This time it was
a little bit
darker – almost khaki colored - but not the dark chocolate
color I'm used
to. </p>
<p class="MsoNormal">We paid extra attention to washing the
floor and again
painted all surfaces and edges.<span style="mso-spacerun:yes">
</span>After
laying the floor a second time, it was still doing the same
thing with our
shoes.<span style="mso-spacerun:yes"> </span>We tried
several tests using
different coats of paint and ultimately discovered it would
take four coats of
paint to resist scuffing.</p>
<p class="MsoNormal"><br>
</p>
<p class="MsoNormal">It’s been about a week since we finished
the last coat and yesterday
we had to lay <span style="mso-no-proof:yes">tape</span> down
on the floor to
mask out an area to paint a safety line. Today, when we went
to pull up the <span style="mso-no-proof:yes">tape,<span
style="mso-spacerun:yes"> </span>some</span>
of the top <span style="mso-no-proof:yes">layers</span> of
the <span style="mso-no-proof:yes">floor</span> came up with
it. The tape was down
for 24 hours. The floor had over 48 hours to dry. </p>
<p class="MsoNormal">I’m certain we may have a manufacturing
issue with the
lumber.<span style="mso-spacerun:yes"> </span>The paint is
adhering and doing
its job. Rosco has checked the batch number and everything
checks out.<span style="mso-spacerun:yes"> <br>

<p class="MsoNormal">Has anybody experienced this? </p>
