    As the charge painter at The Old Globe Theatre, I am tasked every year to “touch up” the set for “How the Grinch Stole Christmas”. This set is now over 20 years old and the floor in particular has been repainted every year. We start by sweeping and mopping, then a fresh coat of Break Through Black is applied by roller. After dry, the spike marks are uncovered and we reapply some snow dots, then the prop crew puts a Mop-N-Glo finish on the floor. Throughout the run of the show the Mop-N-Glo is reapplied.

    We have noticed in the past couple of years that the paint in some areas is becoming a blister that, when started, wants to peal off in large sheets. I think this is a function of too many coats of paint. But, I would love some advice or input from the experiences within the group as to what could be causing this and/or any remedies that you would suggest. Thanks in advance.

    Breakthrough is usually pretty good about sticking to itself.  I think it’s probably the Mop-N-Glow that’s your problem.  After 20 years though, I think that poor floor deserves to be changed out for new.  There’s only so many layers of paint you can build up before you just have too much thickness.  Paint is not structural.  Even if it didn’t peel, at some point it would start just chipping out because you probably have somewhere between 1/4 to 1/2 inch (or more) of thickness on there already.  Most places will pro-rate the cost of that floor out for another 20 years.  Push for new.

    I agree with you about the layers of mop n Glow and paint. I might be able to help. We make Jaxsan Coatings and we have successfully used Jaxsan 600 on wooden stage floors to coat and repair the surface. Applying a rubbery finish to the floor will not change the brittleness of the underlying paint layers but it may give you a another few months or years. If you would like a sample container of Jaxsan 600, go to my web page JaxsanCoatings.com and request a sample and provide a shipping address. We are happy to help. I really encourage samples because every situation is different and this is a try it and see type of fix.

    Mop n Glo has rosin in it. So essentially you’re building up layers of paint, glo, paint, glo.. and each time glo is added it’s reactivating the lower layers of glo via the surfectants and the alcohol in the product.. so the rosin is going liquid down there then reforming.

    Hence, bubbles. Scrap the crap out of the surface and break as many bubbles as possible, sand their edges smooth = do this very aggressively – then prime the heck out of it with something industrial. If I was working in the theme parks I’d put down an automotive primer. We have to do this with water rides because they bubble from water seep all the time.
