Application Instructions

Proper surface preparation is important to ensure optimal adhesion. Clean the surface of all debris, dust, and dirt. The surface should be dry. The application temperature minimum is 60°F (15.5°C) and rising. If the temperature is predicted to drop below 50°F (10°C) within a 24 hour period, do not apply. Also, do not apply is rain is imminent or forecasted within a 24 hour period. If the area is one in which fog or dew is prone to accumulate in the evening, coat in the morning and complete by early afternoon (3:00 pm) in order to prevent wash off (which occurs if fog, dew, or rain moves in before the coating is dry). Wear gloves and eye protection when mixing and applying Pro Seal #905. To apply, thoroughly stir the pail and apply via brush, trowel, or airless spray unit (Tip Size: .021 to .025). Apply at a rate of 150 square feet per 5 gallon pail. Let material dry for 24 hours before applying foam, drainage boards, or backfilling (depending on weather conditions). Do not allow material to dry on tools; for clean-up, simply wash with soap and water.
