XS Foam Rails
XS Foam Rails are the best-kept secret in the industry for achieving the quickest mold building. Each box includes sixteen 4-foot lengths of precision-cut foam featuring a square profile with a thickness of 1.5 inches.

The XS Foam Forming System is elegantly simple: eliminating ripping material, screwing, nailing, and in most cases, caulking to create the side rails in forming precast projects. It consists of 4 elements:
- Polystyrene foam rails
- Clear facing tape
- PSA tape
- Reusable urethane flexible edge profiles (optional)
Whether forming from ¾” (1.9cm) up to 2” (5cm) thick, form edges are true with no bleeding between the casting surface and XS Forming. Installation tools required are just a tape measure, pencil, and knife.
XS Foam Rail – Common Square Edge
- Thoroughly clean the casting surface with denatured alcohol or acetone.
- Select XS Foam rail for appropriate thickness.
- Remove 1st protective film layer of PSA tape and apply tape to the bottom of the foam rail, keep the edge of the tape even with the inside edge
of foam rail. - Cut to desired dimensions
- Remove 2nd protective film layer and begin applying foam rails to the casting surface as required.
- Foam rails may be bent into desired shapes or radii. Clear-facing tape must be applied to the outside of the bend. Multiple bends require
taping on both sides of the foam rail. Tape that wrinkles in the process must be replaced if on the inside of the form against pour. Apply PSA tape after bending is complete. Depending on radius PSA tape may have to be applied in short lengths to achieve bend. - Apply the corresponding thickness of clear-facing tape to span across the inside of all foam rails spanning across joints.
- Remove the protective film layer from clear-facing tape.
- Thoroughly clean the casting surface again with denatured alcohol or acetone.
