WHAT IS EXPANDOTHANE?
ExpandoThane™ is an expanding waterproofing compound.
It contains micro blowing agents that create a tough and flexible waterproofing membrane capable of sealing the gaps and crevices. This amazing formula allows for a barrier between the outside and the interior of a foundation wall or applied as a secondary roof covering that completely eliminates the water from finding a way in. Standard polyurea will not fill the gaps in between crevices, or bug holes, because it was designed to mimic the contours of the object being sprayed. On the other hand, ExpandoThane expands in those holes and crevices 7 times the volume sprayed.
THE ULTIMATE WATERPROOF MEMBRANE
ExpandoThane™ was created in 2004 and is used for a Protective Roof Coating, Specialty WaterProof Coating and any areas needing a high build Waterproof Coating. It is 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. It may be applied directly over existing roof substrates such as metal, modified bitumen, BUR, CONCRETE, EPDM, TPO, and spray urethane foam. It also makes a great waterproof membrane for foundation walls.
When applying Expandothane as a flat seamless roof system you can save cost 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 the Poly-Sil 2500 TopCoat especially designed for use with the ExpandoThaneTM System.
IMPACT FOR HAIL DAMAGE BY GARDNER IMPACT IMPACT TEST WAS CARRIED OUT WITH MAXIMUM CAPACITY OF IMPACT TESTER (80IN.*4LBS) 320 INCH POUNDS. NO BREAKING OR CRACKING WAS OBSERVED IN THE THREE LAYER COATING SYSTEM.
ExpandoThane Polyurea 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 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.
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.
