UNIBASE™
Adhesive/Basecoat Mixture uses a mix ratio of
two parts UNIBASE to one part Portland cement
by weight. This ratio provides an acrylic-rich
adhesive and basecoat that dries to a strong and
durable yet flexible coating with excellent
adhesive and weather resistant properties.
Recommended Use
UNIBASE Adhesive/Basecoat Mixture is used to
adhere expanded polystyrene insulation board
(EPS) to approved exterior substrates and to layer
EPS to EPS in order to create unique architectural
details. COREVNET reinforcing meshes are
embedded in the UNIBASE Mixture to create the
basecoat lamina for the PRECOR EIFS.
UNIBASE Mixture may also be used without EPS
to level surfaces of concrete or unit masonry in
preparation for application of Corev finish
coatings. UNIBASE Mixture should never be
applied directly to wood substrates of any kind.
Coverage
Each 5 gallon bucket of UNIBASE
Adhesive/Basecoat Mixture covers approximately:
Basecoat Only 190 Ft2
Adhesive Only 160 Ft2
Basecoat/Adhesive 85 Ft2

Properties
Working Time
After mixing with Portland cement, the working
time of UNIBASE Adhesive/Basecoat Mixture is
approximately 30-60 minutes, depending on
ambient temperature and humidity.
Drying Time
For adhesive applications, UNIBASE
Adhesive/Basecoat Mixture must dry for a
minimum period of 24 hours to form a positive
bond before further work over newly installed
EPS insulation board or other surfaces. Low
temperature and high humidity may extend set
time.
For basecoat applications, drying time depends on
weather conditions. Protect newly applied
basecoat from rain and temperatures less than
40°F (4°C) for a period of 24 hours. In cool
temperatures and/or high humidity, longer
protection may be required. Average drying time
at 70°F and 70% humidity is 12 hours.
