Notes and considerations

  • Casting Skin can be softened and manipulated using a small amount of heat.  If using a heat gun use on lowest setting and be careful to not melt the plastic.
  • If applying over a pourous surface like MDF board it is recomended to seal the surface prior to application to insure a good bond.
  • Casting Skin works best with the use of a release agent prior to casting
  • For casting requirements that are over 60" wide Casting Skin may be jointed using the overlap method.
  • Our 12 mil Ultra Thick Casting Skin can be lightly sanded (practice on a small sample piece)

    This product works awesome if you’re looking to cast long, seamless pieces. Easy to apply to a substrate and use multiple times if you use a form release and take care when demolding casts. Great product with great customer service !
