TECHNICAL DATA
FEATURES BENEFITS
One-component Ready to use; easily mixed with water on the job site
Polymer-modified Excellent adhesion; increases durability and freeze/thaw resistance
Smooth consistency Trowels on easily; increases productivity
Vapor permeable Allows substrate to breathe naturally; resists blistering due to vapor
Factory blended Portland Cement Assures performance mix ratio
Low cement ratio Less alkalinity, less free lime, less efflorescence
Bagged powder product Less solid waste
SURFACE PREPARATION
Adhesive Preparation:
Ensure surface is clean, dry and free of surface contamination. Install insulation board with adhesive
within 30 days of the application of Decoplast Weather-Resistive Barrier or clean the surface and
recoat with Decoplast Weather-Resistive Barrier .
Concrete / Masonry
Surfaces must be clean, dry and free of frost, damage and all bond inhibiting materials, including dirt,
efflorescence, laitance, form oil and other foreign matter. Loose or damaged material must be removed
by water blasting, sandblasting or mechanical wire brushing and repaired. Avoid application over
irregular surfaces. Resurface, patch or level surfaces to required tolerance and smoothness with
appropriate Decoplast leveling materials.
ASTM C 1177— Glass Mat Gypsum Sheathing
Ensure surface is clean, dry and free of surface contamination. Sheathing must be installed and
protected in accordance with manufacturer’s and building code requirements. Remove and replace
weather damaged sheathing. Avoid application over irregular, out of plane surfaces. Install insulation
board with adhesive within 30 days of installation of the sheathing.
Base Coat Preparation:
Insulation board must be rasped and free of all bond inhibiting materials.
Concrete or Masonry
Surfaces must be clean, dry and free of frost, damage and all bond inhibiting materials, including dirt,
efflorescence, laitance, form oil and other foreign matter. Loose or damaged material must be removed
by water blasting, sandblasting or mechanical wire brushing and repaired.

Use 5-6.5 quarts (4.7-6.2 L) of clean, potable water per 50 lb. (23 kg) bag of Decoplast Dry Base Coat.
Mix with a clean, rust-free electric drill and paddle. Allow to set approximately five minutes, adjust
mix if necessary by adding up to 12 fl.oz. (0.35 L) of water per bag, remix to a uniform consistency.
Avoid re-tempering after mixing of product. Do not exceed maximum amount of water in mix ratio.
MIXING
APPLICATION
Apply only to sound and clean, dry, properly prepared, frost-free surfaces.
As an Adhesive:
Apply to the back of the insulation board with the appropriate size notched trowel. Form uniform ribbons
of adhesive parallel to the short dimension of the board so the ribbons are oriented vertically in relation
to the plane of the wall. Immediately install the board horizontally with staggered joints and apply firm
uniform pressure over the entire board surface. Do not delay installation once adhesive is applied.
As a Base Coat:
Apply with a stainless steel trowel to an approximate thickness of 1/8" (3 mm). Work horizontally or
vertically in strips of 40” (1 m) and immediately embed Decoplast Reinforcing Mesh in wet base coat by
troweling from the center to the edges of the mesh. Avoid wrinkles in the mesh and smooth the base coat
to eliminate trowel marks. Minimum recommended dry thickness of the reinforced base coat is 1/16"
(1.6 mm) when dry. Reapply additional base coat if necessary to achieve minimum thickness as soon as
the first application is dry. Embedded mesh in base coat should not be visible.
As a Skim Coat:
Apply in one application to a maximum thickness of 1/16" (1.6 mm) to the prepared surface and smooth
the surface.
Curing/Drying
Dries within 24 hours under normal drying conditions [70ºF (21ºC), 50% RH]. Allow additional drying time
during cold, humid, or wet weather until insulation board is fully adhered before rasping, and before
application of primer or finish to hardened Decoplast Dry Base Coat. Protect from rain, freezing and
continuous high humidity until completely dry. Decoplast recommends using Decoplast Primer prior to
application of finish.
Clean Up
Clean tools and equipment with water immediately after use. Dried material can only be removed
mechanically.
LIMITATIONS
Use Decoplast Dry Base Coat only when surface and ambient temperatures are above 40°F (4°C) during
application and drying period.
Sloped surfaces: Refer to Decoplast details.
Decoplast Dry Base Coat should not be used on weather-exposed horizontal or below grade surfaces or
where immersion in water may occur.
Prevent rapid loss of moisture from exposure to direct sun, wind and high temperatures.
Decoplast Dry Base Coat should not be used as a finish coating.
