How to use

Usage Use Valspar Duramax Exterior Paint on properly prepared exterior wood and metal siding and trim including hardboard, fiber cement board, vinyl, primed metal, shakes, brick, cement, cinder block and stucco. Do not use on glazed brick, floors or steps.
Prep Thoroughly clean the surface and allow to dry. Remove all dirt, dust, chalk, rust, grease, wax and mildew.
Application Stir thoroughly and intermix multiple containers. Apply only when paint, surface and air temperatures are 35–90 °F (7–32 °C) during application and drying time. Do not paint if temperatures are expected to be below 35 °F (7 °C) within 48 hours of application or when heavy dew or precipitation is expected in the next 12 hours. These recommendations are a starting point only. Due to variability in sprayers, we recommend testing your spray pattern and flow before proceeding. Always paint back into freshly painted areas and end up at a door, window or outer edge. Move windows after 1 hour to prevent sticking.
