Substrate

Application of a prime coat is necessary to equalize surface porosity. After prepared surfaces have thoroughly

dried, apply a prime coat of S

Brand First Coat flat latex paint or a good quality interior latex flat wall

paint with high solids content. Prime coat should be applied undiluted and allowed to dry before decorating.

Mixing

Use a clean vessel equipped with power agitator. For initial mix, stir powder into recommended amount of water,
agitating during powder addition. Allow to soak for at least 15 min.—longer in cold water. Remix until a creamy,
lump-free mix is obtained. Adjust spray consistency by adding small amounts of powder or water. Overthinning
can create an undesirable finish or “soft wall” or chalky condition. Overdilution can also entrain excessive air
and foam.

Application

Using suitable spray equipment, apply by machine to create the desired effect. The application rate will vary
from 10 ft.

/lb. (2 m

/kg) to 40 ft.

/lb. (8.2 m

/kg) depending on texture pattern. Maintain 55 °F (13 °C) minimal

air, product, and surface temperature during application and until surface is dry. Avoid drafts while applying, but
provide ventilation after application to aid drying. Do not use unvented gas or oil heaters. May be painted after
overnight drying. Unpainted surface is not washable or scrubbable. Match spray equipment to job size and time
requirements. For rapid application and high production, use either a piston pump (7:1 or larger) or a rotor sta-
tor pump matched to a compressor of adequate size. Preferred texture patterns can be obtained using a Binks
18D spray gun (with #57 or 58 fluid nozzle with R27 or R30 fan cap) or Binks 7E2 spray gun (with #46 fluid
nozzle with #190, 191, 290, 291, or 292 fan cap). Fan caps with a rectangular orifice reduce overspray and
waste and will provide greater spray control. Good results can also be obtained using a short pole gun with a
3/8

Љ nozzle orifice. Small jobs can be completed using a Hopper Gun or Goldblatt Pattern Pistol with separate

compressor.
