Another name for Cementitious Stucco is Traditional Stucco, it was most commonly used
in the in the early 1900’s. EIFS (Exterior Insulation Finish System) or acrylic stucco
became popular around the 1980’s.
There are a few differences between the two systems, mainly what it is made out of,
cementitious or traditional stucco is made out of Portland Cement while the acrylic
stucco is made out from… you guessed it acrylic resins and/or polymers.
With Cementitious Stucco the range of textures you can achieve are limitless, from
smooth to rough and everything in between. Different sized sand is used in order to
create a wide rage of textures.
Since Cementitious Stucco is a cement based product, the colours tend to not be as bright as
the Acrylic. When choosing Cementitious Stucco, lighter colours are recommended for this
One of the most common problems with Cementitious Stucco is that it can shrink and crack
with the freeze-thaw cycles in Edmonton. This is why Acrylic Stucco is more common in
newer builds because of the elasticity of the polymer finish which will expand and contract
with the weather cycles.
