SAFETY FIRST!
Follow good safety practices.
Read material safety data
sheets and related literature on
products before specification
and/or installation.
Application
During and after application, and at all times until building is occupied, maintain min. air, water, mix, and surface
temperatures of 55 °F (13 °C), and provide adequate ventilation for texture to dry properly. Inadequate ventilation
can cause objectionable board deflection and reduced texture bond/surface hardness. Do not use unvented gas
or oil heaters.
Correct equipment settings and mix consistency will maximize coverage (in ft.
2
/lb.), yet reduce aggregate fallout
(bounce-back) and holidays (board voids). A steady, high-pitched sound should be heard from the pole gun
during spray application. Slight adjustments for type and grade of aggregate in the texture may be necessary.
Adjust air spike, orifice, and air pressure to optimize atomization and width of spray fan. As the pole gun orifice
wears, it will slowly increase in size—periodically check and adjust it as necessary.
Spray texture mix on dry surface at a maximum rate of 8-10 ft.
2
/lb. For heavily textured appearance, apply
two coats of texture, letting the first coat dry thoroughly before applying the next. (Do not vary coverage rate:
check-cracking can result from excessive coating thickness, and poor hide from too thin a coating.)
