SeamTight is also a product we manufacture, so it is compatible with our RvRoofMagic and an excellent filler for around vents and conditioners, as well as for reinforcing seams. For seams, apply the product 6 inches over the left and right of the seam.  Then you will roll out our fabric and embed it in SeamTight using a dry paintbrush so the SeamTight is absorbed into the fabric's fibers. Let that set overnight, then apply RvRoofMagic over the entire roof. At this point, your seams are fully encapsulated, and you will never need to worry about them again!

Seam Tight effectively protects your roof against alligatoring and other damaging conditions with the SeamTight roof repair product. Designed for 400% elongation, 1000 PSI tensile strength, and UV stability, the result is a strong yet flexible membrane that can withstand roof wear across seams, fasteners, and penetrations. Any unused product has a 3-year shelf life.

Can be used on the following roof types

• EPDM
• Metal Buildings and Roofs
• Modified and BUR Roofs
• Urethane Foam Roofs
• Single Ply Roofs (EPDM)
• TPO
• Concrete

Outstanding adhesion properties for seams and around vents and AC units

SURFACE PREPARATION

The surface must be free of any oils, moisture, rust scale, soil, or other contaminants that may interfere with good adhesion. Remove any loose material from seams or other surfaces with a wire brush or scraper. Oil and grease should also be removed with solvents or an appropriate cleaner, such as our RoofProtect. In many cases, high-pressure water blasts will be sufficient to prepare the surface.

APPLICATION TEMPERATURE

For best results, the ambient air and substrate temperatures should be between 50°F and 110°F. Although lower temperatures can be used for brush applications, the product temperature must be at least 70°F when pumping.

APPLICATION METHODS

SeamTight can be brushed or rolled. Apply heavy, uniform coats over fasteners, seams, etc, to ensure maximum coverage
