LIMITATIONS:
Not intended for patches over 1" deep. For these patches it is recommended to use screening or other material to cover the hole and provide a backing, then place OnePass on top of the backing. This material should not be applied to substrates that may swell or deteriorate due to moisture exposure, or areas that may flex.
USES:
OnePass is used for general construction and repair of wallboard, cement board, magnesium oxide board, plaster, smooth stucco, masonry, some wood repair applications, and many other surfaces. OnePass can also be used as a texturing material. OnePass is weather resistant, and durable in both exterior and interior applications.
SURFACE PREPARATION:
The bonding surface shall be clean, sound and free from any materials that may inhibit bond such as oil, paint, chalk, splinters, dirt, and loose materials.
MIXING:
Do not exceed one part clean potable water to 2 parts OnePass. First place the water in the mixing container, then add the OnePass powder. Mix to a workable, lump free consistency by hand or mechanical mixer.
PLACEMENT:
Apply OnePass with a trowel or putty knife. You have approximately 20 minutes working time at 70°F. Place quickly and cleanly to allow for maximum finishing time. Material may be sanded when dry (approximately 45 minutes after adding water).
TEMPERATURE:
Warm temperatures will reduce the working time of OnePass and cold temperatures below 70°F (21°C) will increase the working time. To adjust the setting time, use warm or cold mix water. OnePass should not be applied if surface or ambient temperature is below 45°F (7.2°C).
WARNING:
May cause skin, eye, and lung irritation. Avoid contact with skin, eyes, and clothing. Wash thoroughly after handling. Wear appropriate safety and protective equipment. DO NOT TAKE INTERNALLY. In case of contact, flush affected areas with water for 15 to 20 minutes. If irritation persists, seek medical attention. Wash contaminated clothing.
