Working Conditions:

  • Use in a dust free & ventilated area.

  • Wear gloves & glasses.

  • Surfaces to be covered must be dust free and uncontaminated.

  • Stir sticks and mixing vessels must be clean and uncontaminated.

  • Do not reuse stir sticks, mixing vessels, or brushes between applications.

  • Temperature should be between 70 & 80 degrees F.


  • Stir PART A completely before mixing with PART B.

  • Mix 5 parts by volume of PART A with 1 part by volume of PART B in a glass container.

  • Stir gently until mixture is one color, specially around the edges.

  • Working time is approx 15 minutes, so mix only that which you can use in 10 minutes.

  • Pour the mixture over the surface to be covered.

  • Spread the mixture quickly with a clean foam brush. Use as few brush strokes as you can.

  • Apply a thick enough coat for the liquid to flow, but not too thick for it to run or drip. Practice with scrap foam first.

  • Avoid going over areas already covered. Minor brush marks will disappear in a few minutes.

  • Leave undisturbed for 24 hours.


  • Liquid Sheeting may be painted with most common paints, although we advise using foam safe or water based paints.

  • Test on scrap foam to ensure that the paint you are using does not attack Liquid Sheeting.

  • Lightly rub the surface with steel wool or use a light coat of primer paint for better paint adhesion.
