  2. When surface moisture leaves, trowel apply light second coat in random directions.




Light Dash
Suggested application procedures
  1. Apply a first dash coat to produce complete color coverage.
  2. Apply a second dash coat for texture depth and uniformity when first coat is dry using a plaster mix of thinner consistency.
  3. Use proportionately more atomizing air at the gun nozzle.




Medium Dash
Suggested application procedures
  1. Apply a first dash coat to produce complete color coverage.
  2. Apply a second dash coat for texture depth and uniformity when first coat is dry.
  3. Use a medium amount of atomizing air at the gun nozzle.




Heavy Dash
Suggested application procedures
  1. Apply a first dash coat to produce complete color coverage.
  2. Apply a second dash coat for texture depth and uniformity when first coat is dry, mortar to be of relatively stiff consistency.
  3. Use relatively less atomizing air at the gun nozzle and lower water ratio of the plaster.




Tunnel Dash
Suggested application procedures
  1. Apply first dash coat to produce complete color coverage.
  2. When surface moisture leaves, or on second day, apply a second heavy coat.
  3. Use low atomizing air and reduce water ratio of the plaster.




Knockdown Dash
Suggested application procedures
  1. Apply first dash coat in thin consistency to produce complete color coverage.
  2. Apply a coarse second dash coat for texture depth and uniformity, allowing some of the first coat to show through.
  3. Trowel lightly after moisture leaves surface.




Cat Faces
Suggested application procedures
  1. Trowel, float or dash on a first coat to completely cover base.
  2. Apply second coat and steel trowel to a smooth finish, leaving the first coat exposed in the design specified.
Note: An excelerator can be used in the first coat. Smooth finishes are subjected to moderate cracking. Also, "burn" lines and color mottling can be expected. TSIB recommends further decoration of this finish with an approved coating.

  2. Apply a thin texture coat with trowel in a random pattern, overlapping strokes.
  3. Flatten higher areas with trowel.




Smooth
Suggested application procedures
  1. Trowel, float or dash on a first coat to completely cover base.
  2. Apply second coat and steel trowel to a smooth finish.
Note: An excelerator can be used in the first coat. Smooth finishes are subjected to moderate cracking. Also, "burn" lines and color mottling can be expected. TSIB recommends further decoration of this finish with an approved coating.




Santa Barbara
Suggested application procedures
  1. Apply Brown coat with a rounded trowel, creating undulation in the brown coat.
  2. When applying the finish, trowel, float or dash on a first coat to completely cover base, apply second coat and steel trowel to a smooth finish, leaving minor tool marks and "open" areas.
Note: An excelerator can be used in the first coat. Smooth finishes are subjected to moderate cracking. Also, "burn" lines and color mottling can be expected. TSIB recommends further decoration of this finish with an approved coating.




Fine Sand Float
Suggested application procedures
  1. Trowel on a finish coat and double back with a second a application. Plaster mix is to be formulated with a blend of 20- 30 mesh aggregate.
  2. Using circular motion, rub surface with float to achieve uniform pattern, bringing sand particles to surface, an absolute minimum of water should be used in floating.




Medium Sand Float
Suggested application procedures
  1. Trowel on a finish coat and double back with a second application. Plaster mix is to be formulated with a 20-mesh aggregate.
  2. Using circular motion, rub surface with float to achieve uniform pattern, bringing sand particles to surface. An absolute minimum of water should be used in floating.




Heavy Sand Float
Suggested application procedures
  1. Trowel on a finish coat and double back with a second application. Plaster mix is to be made with coarse aggregate or relatively coarse blend.
  2. Using circular motion, rub surface with float to achieve uniform pattern, bringing sand particles to surface. An absolute minimum of water should be used in floating.




Scraped
Suggested application procedures
  1. Apply finish coat approximately 1/4 in. thick and allow to take up until surface moisture leaves.
  2. Scrape vertically with a steel joint rod or trowel held at right angles to the plane of the wall. Remove sufficient material to leave a torn surface, free from smooth spots and joinings.




Spanish
Suggested application procedures
  1. Trowel on a first coat, leaving relatively smooth.
  2. Apply second coat in random texture, using overlapping strokes of the trowel.




Monterey
Suggested application procedures
  1. Trowel on a first coat, leaving relatively smooth.
  2. Apply second coat in a random texture, using overlapping strokes of the trowel.




Arizona
Suggested application procedures
  1. Trowel on a heavy texture coat.
  2. After surface moisture is absorbed, apply heavy second coat, leaving it rough under the trowel with small area texture pats.




Frieze
Suggested application procedures
  1. Trowel on a first coat using double-back method, and rake with a coarse brush or broom.
  2. Splatter dash sparingly with dash broom, using mortar of fairly stiff consistency to partially cover the surface.
  3. After moisture leaves surface, trowel down high spots, retaining general pattern of dash texture.




English
Suggested application procedures
  1. Trowel on a first coat to completely cover base.
  2. Using a rounded trowel, apply a thick texture coat with short strokes in varying directions, leaving a rough, irregular pattern.
  3. After moisture leaves surface, trowel down high spots, retaining general pattern.




Trowel Sweep
Suggested application procedures
  1. Trowel on a fist coat to completely cover base.
  2. Apply a second coat with fan shaped strokes, lapping each other so as to form narrow, high ridges where mortar flows over the toe of the trowel.




Web
Suggested application procedures
  1. Trowel on a first coat and broom lightly in varying directions, using a sweeping motion.

  3. Trowel surface lightly.




Briar
Suggested application procedures
  1. Trowel on first coat to completely cover base.
  2. Apply a texture coat, holding trowel at angle to surface, with hell of trowel serving as a pivot point, produce fanlike ridges in radiating pattern.

Combed
Suggested application procedures
  1. Apply finish coat in sufficient thickness to accommodate depth of grooves without exposing base (brown) coat.
  2. Rod and darby, leaving surface reasonably straight and true.
  3. Using a strip as a guide, comb surface vertically (or horizontally) with a template, formed to achieve pattern detailed on drawings.

  2. Straighten with rod and darby, leaving surface reasonably smooth.

  3. Cut shallow groove on each side of simulated timber.
  4. Lightly trowel face of simulated timber to relatively smooth surface.
  5. If peg marks are desired, lightly press large screw head near ends of simulated timber.




"Wet" Grooved Plaster
Suggested application procedures
  1. Apply finish coat 1/4" to 3/8" thick over the damp base
  2. Rod and Darby
  3. Layout the design as shown on drawings. To simunlate joints, stamp in lines witha joint rod or rake out with a raking tool.

Brick
Suggested application procedures
  1. Trowel on a first coat of mortar-colored joint material.
  2. Trowel on a second coat of brick-colored stucco material.

Rock 'n Roll
Suggested application procedures
  1. Trowel on a first coat to completely cover base coat.
  2. Apply a second coat of a specially prepared finish plaster containing selected size pebbles to achieve desired texture.
  3. The action of the trowel or float rolls the pebbles to create miniature troughs in a linear or circular pattern.




Glacier
