Asked by: Joe
Yes, but not using spray paints (generally). They'll dissolve the foam.

is this rated at 25 pounds per square inch?

Asked by: 3/4
I don't know what you want to know and don't know about compression but has almost none tensile or shear strength. Place a piece between two separated four by fours and step in the middle and see if you are satisfied about the strength.
