We are now offering ExpandoThane Roofing!

Our ExpandoThane product is an expanding polyurea waterproofing compound to use on your flat roof. Our material contains micro blowing agents that create a tough and flexible waterproofing membrane capable of expanding 5 to 7 times its volume. When applied to your flat roof,this amazing formula allows for a barrier between the outside and the interior of a foundation wall or applied as a roof coating that completely eliminates the water from finding a way in. Standard polyurea will not fill the gaps in between crevices, or bug holes, on your flat roof because it was designed to mimic the contours of the object being sprayed. However the ExpandoThane material will expand in those holes and crevices 5-7 times the volume when on your flat roof. Its’ high elongation and tear strength give it incredible performance, bridging seams and expansion joints. ExpandoThane comes in either the cartridge material canisters or by the gallon, in different quantities.

ExpandoThane Polyurea Flat Roof Coating when applied at 2 1/2 gallons per hundred square feet (40 wet mills) cures in seconds to leave you with a full 1/4″ Polyurea Waterproofing Membrane. ExpandoThane Polyurea may be applied as a secondary roof covering over flat roofs, metal roofs, modified bitumen, tar and gravel TPO, EPDM roofs, BUR, Concrete and Spray Urethane Foam. ExpandoThane also makes a great Polyurea membrane for waterproofing foundation walls before back filling with dirt.

ExpandoThane is a VOC free Plural component Polyurea with micro blowing agents to create a flexible polyurea that expands five to seven times its volume to span gaps and fill bug holes on your flat roof.

Protecting the foam or the ExpandoThane or any roof coating is easier and faster with the spray on application, but it is available to be brushed or rolled on as well. Poly-Sil 2500 Roof Coating is a single component spray grade high solids VOC free material available in white, and light or dark grey colors. No thinning or reducing is required and only a single application is needed. If applying a second coat, please be sure the first coat is cured and dry before proceeding.
