Portland Cement Plaster (Stucco)
Portland
cement plaster is a versatile facing material that can be applied
to flat or curved surfaces either inside or outside any building
or structure.
Portland cement
plaster is a combination of portland cement-based cementitious material
and sand mixed with a suitable amount of water to form a plastic
mass. The plaster will adhere to a surface and harden, preserving
any form and texture imparted to it in its plastic state.
Plaster in its
hardened state is a desirable facing material: hard, strong, fire-resistant,
rot- and fungus-resistant, color-retentive, and durable under wet-dry
or freeze-thaw weather cycles. Plaster has proved to be a durable
wall cover in all climates from the very hot to the very cold. It
has great appeal as a surface finish because of its utility, low
first cost, and minimum need for maintenance.
The final appearance of the finish coat can be varied by changing
the size and shape of the aggregate, using colored plastic (stucco)
cement or masonry cement, adding pigments, changing the consistency
of the finish mix, the method or equipment used for plastering,
and the plasterer's skill in manipulating the finish coat.

Cement Plaster (Stucco)—A Hard System to Beat (PA395)
Stucco for Building Color and
Texture
Traditional portland cement plaster is an extremely versatile,
time-tested exterior finish, frequently referred to as “stucco.”
It consists of portland cement-based materials and sand, mixed with
water to form a workable plaster. The key ingredient, portland cement—the
same material that is the basis for the hardened properties of concrete
used to build super-highways, bridges, and skyscrapers—provides
strength, durability, and toughness in portland cement plaster.
As an exterior cladding, stucco is cost-effective and tough enough
to resist damage. That inherent toughness is beautifully complemented
by the variety of colors and textures available. Color is determined
by selecting cement and aggregate color, and quite often modified
by adding mineral oxide pigments to the plaster mix. White portland
cement makes it possible to achieve the widest range of colors for
the stucco finish, including bright white. Factory-prepared finish
coat products, which are available in many areas, often contain
white cement. These pre-pigmented, packaged cements offer ease of
use for achieving the desired stucco color, but it’s also
possible to add preweighed mineral oxide pigments to the finish
coat stucco during mixing.
Texture gives substance and character to the plaster surface. It
can be used to provide highlights, depth, continuity, segmentation,
and even achieve the look of a completely different construction
material such as wood timbers, brick, or stone masonry construction.
Texture is achieved by selecting aggregate size, controlling finish
mix consistency, and using special treatment techniques during and
after application of the finish coat plaster.
Color and texture add dimensions to your projects. To confirm the
suitability of a desired color and texture, be sure to ask your
plasterer to provide a sample panel for evaluation prior to starting
work.
