ExpandoThaneTM was created in 2004 and is used for a Protective Roof Coating, Specialty WaterProof Coating and any areas needing a high build Waterproof Coating.


ExpandoThaneTMis a VOC free Plural component hybrid with micro blowing agents to create a hard skin that expands five to seven times its volume to span gaps and fill bug holes.


ExpandoThaneTM is an aromatic which sprays a light grey color. When applying ExpandoThaneTM as a flat seamless roof system you can give your customer cost savings by leaving it this color and applying pea gravel over it or should you elect to we have a single component Aliphatic Polyurea in White and other colors, as well as our own SiliconeSeal 3000 especially designed for use with the ExpandoThaneTM System.


We recommend when applying ExpandoThaneTM that the final thickness be 1/4'' for best results.


ExpandoThaneTM may be applied as a secondary roof covering over Metal Roofs, Modified Bitumen Roofs, BUR, Concrete and Spray Urethane Foam. ExpandoThaneTM also makes a great membrane for foundation walls before back filling with dirt.
