ROOF X TENDER® 99 Cold Weather Primer is a high penetrating primer developed specifically for ROOF X TENDER® tapes. ROOF X TENDER® 99 is based on VOC exempt solvents and synthetic adhesive polymers to provide an aggressive bonding agent for use in cold weather applications and on difficult to adhere surfaces. RXT-99 meets federal environmental standards from an atmospheric pollution regulatory perspective and is designed to work with all ROOF X TENDER® tapes. This product should be used on applications using ROOF X TENDER® Tapes when temperatures fall between -30°F and 40°F. It is also widely used as a coalescing agent on surfaces which have difficult to remove dirt or particulate matter. Finally, it is a great primer for porous surfaces such as concrete, brick, mortar and wood to improve adhesion of ROOF X TENDER® tape products. This product is not recommended for use on PVC.
All surfaces must be dry prior to application. Using appropriate brush or tool, remove all dirt, debris, talc, rust, scale, grease, and any other foreign contaminants that are present prior to application. Do not use ROOF X TENDER® 99 Primer on PVC roofs. In extreme cold weather keep the rolls warm to aid adhesion. In hot weather (80°F+) keep rolls in a cooler and/or shade to aid in application.

RXT-99 can be applied using a roller or brush. RXT-99 is used to prepare surfaces for application of all Roof X Tender® tapes. It is recommended to store product at ambient room temperatures before using in freezing temperatures. This will simply make application easier and help provide a thin and consistent film.
