Application: Fill the lowest part of the cavity first. When using Expanding Sealant, fill only 40% with foam since formula expands approximately 2-1/2 times. Temperature of the surface to be foamed should be 40-95° F. Optimal can temperature is 70-80°F. Expanding Sealant will withstand continuous temperatures up to 195° F.

Step Liners With Step Liners, shaping overhangs becomes a snap. Use spray adhesive and/or roofing tacks to fasten Step Liners to the inside of formwork.

Step Liners may be stripped and finished much earlier than conventional forms because it acts as a foam cushion against concrete.Use MASCO Bio Release Waterbased form release agent on form surface.
