uncurling the mass-loaded vinyl
« on: May 11, 2012, 02:33:14 AM »
Any tips about getting the curl out of the mass-loaded vinyl, that comes from being rolled up? 
If you're using it as a curtain, how do you get the curtain to hang flat?
I'm wondering for the future, for this particular job I straightened the vinyl by taping flat things to it.
thanks

MLV needs to lay flat and acclimate and if your still having some trouble you can use a hair dryer of heat gun to speed things up...

How long does it need to be flat to get the memory of the curl out of it?
I curled it the opposite way overnight but that wasn't long enough.

what thickness did you purchase 1/8" or 1/4" MLV?

did you purchase from us? if so when? ... at that thickness it should uncurl very quickly

This is unusual, ok, unroll the material and place flat on floor curl side up... then put a piece of wood or heavy objects covering the curl area let sit for 24 hours...at room temperature. this should uncurl the material...let me know if this solves the problem.
