In response to requests for a heavier-bodied trowel-applied mastic, Inland Coatings recently introduced RC-2500 medium-grade fiber-reinforced SEBS mastic, which can be trowel or brush applied to roofing seams, flashings, and penetrations where thicker build is required. 

According to product manager, Zak Schneider, “With RC-2500, contractors can easily achieve the desired film thickness in one coat with the convenient, hassle-free application method they prefer. This solvent-based mastic also has exceptional flexibility and elongation properties, enabling it to perform in environments where there are wide temperature swings.”

This rubber-based mastic is currently available in white, packaged in 1-gallon, 3-gallon, and 5-gallon gray metal pails. Black and gray versions of RC-2500 mastic are expected to roll out in the first quarter of 2026. This versatile mastic can be used on a wide range of substrates including metal, EPDM, aged TPO, aged Hypalon, concrete, BUR (asphalt), modified bitumen, and polyurethane spray foam roofing. 

Kenneth Schultz, president of Inland Coatings, reports, “We are excited to be bringing our customers a solvent-based SEBS mastic specially formulated for low-temperature environments that will allow dedicated roof repair and maintenance crews to get the full-bodied single-pass application they’ve been looking for with less labor.”
