20 Choosing a Texture Product

Texture products are available in
machine-applied and hand-
applied types.

Machine-Applied Types
Aggregated powder textures are
spray-applied to an even thick-
ness for fast, complete coverage.
Textures are obtained with vari-
ous aggregates in suitable
binders. They are used to produce
fine to bold, heavy, acoustical-
look finishes. Unaggregated
types, also spray-applied, pro-
duce finer textures, ranging from
light spatter and fog-and-spatter
to medium-light finishes such as
orange peel or flat. Heavier
designs such as spatter and spat-
ter/knockdown may also be pro-
duced.

Hand-Applied Types
These include topping and all-pur-
pose compounds, plus multipur-
pose and ready-mixed textures.
Offer a good range of texture
