[SML] Marley-type floor covering question.

[Ford Sellers]

Christopher asked:

What do you think of my idea of an industrial electric blanket to relax the ripples when they arise?



Ford Responds:

We used to just turn on a lot of lights to heat the Marley (actual Marley brand), making it a little pliable when laying it down.

However, I am not sure whether that would help or hinder the ripple problem, as you are just leaving it installed for years on end... whereas we were using the heat to be able to stretch it properly when installing it for temporary use.



Dick Archer, what do they do in the Dance studio up on the 3rd floor of the Schwartz?

I guess at UCLA you roll your marley up on a regular basis, and then store it.  In the case of my studio, we are heat welding the seems of the panels and leaving them down for years. So we storing the vinyl isn't an issue.



The advisor at Entertainment Flooring Systems was very certain that it is the cycling of temperature, and expanding and contracting of air

that creates ripples.   It occurs to me that in a big theatre like at

UCLA, your stage floor is not cycling in temperature because it is in

a big auditorium, so this may not be an issue for you.   But in a one

room dance studio, we turn the heat off at the end of the day to save money, and so the room can easily cycle 15 degrees in a day/night.



So, I don't know, it could be that this temperature cycling was the cause of the ripples we had in my last marley product.

The vast majority of PVC is not straight enough to be acceptable, but they can be found, and it will take a lot of time to find them.  Be sure you get thick enough PVC pipe.  At the UCLA Dance Dept. we had much better luck with carpet tubing, and it is usually cheaper, sometimes free.

The strength of the tubing becomes very important if you store them on racks hanging on pipes.  Carpet tubes were strong enough if they were kept dry.
