- I. INTRODUCTION:
- This document contains the
Manufacturer's Specifications for Acrylocoat™ Exterior Wall Coating Finish Systems. This is not an Exterior Insulation and Finish
System (EIFS)! EPS foam and the use of
reinforcing mesh is not a necessity in every application. In fact, many different
finishing styles can be “Direct Applied” to numerous different substrates. The
term “System” refers to the various steps necessary to apply the
different textures.
-
- Project design
professionals are responsible for ensuring that our products are suitable for the proposed
project. For assistance in preparing your specification, contact your Acrylocoat™
distributor or Nationwide Chemical Coating Manufacturers, Inc.
-
- II. SUMMARY:
- This document provides the manufacturer's requirements for
the proper applications and procedures for the various aesthetic finishes available with
the Acrylocoat™ system from Nationwide Chemical Coating Manufacturers, Inc.

patching compound (Acrylopatch) used to fill in cracks, holes,
- and
other imperfections on the substrate.
- 2. An adhesive primer
(Acryloprime).
- 3. Polypropylene
reinforcing mesh (Acrylomesh) that is only required when the
substrate is foam or
when the substrate is uneven.
- 4. Basecoat
(Acrylobase) that is only used when mesh is used as part of the
application procedure
and is troweled over the mesh (Acrylomesh)
- 5. Texture coat
(Acrylostuk, Acrylosand, Acrylotex, Acryloseal and Acrylosatin)
- 6. The finish/color
coat (Acryloseal or Acrylosatin).
- B. METHODS OF APPLICATION
- 1. Spray and/or trowel
- C. DESIGN REQUIREMENTS
- 1. Acceptable substrates
for the Acrylocoat Exterior Wall Coating System are:
- a.
Plywood, clapboard, weathered wood, structural insulated
panels (sips), oriented strand board (o.s.b), insulated concrete forms (icfs), primed
metal, galvanized metal, aluminum, tin, copper, Styrofoam, polystyrene, fiberglass, clay,
adobe, stucco, slate, concrete, exterior gypsum board, Dens-glass and various other
substrates.
- 2. Expansion joints
- a.
The location of expansion joints in the Acrylocoat Exterior
Wall Coating System is the responsibility of the project designer. As a minimum, expansion
joints shall be placed at the following locations:
1) Where expansion joints occur in the substrate.
2) Where building expansion joints occur.
3) Where prefabricated panels abut one another.
4) At floor lines in wood frame construction.
5) Where the Acrylocoat Exterior Wall Coating System abuts dissimilar materials.
6) Wherever the substrate changes.
7) In continuous elevations at intervals not to exceed 70 feet.
8) Where significant structural movement occurs such as changes in roofline, building
shape or structural system.
- 3. Terminations
- a.
The Acrylocoat Exterior Wall Coating System can normally
bridge adjoining material substrates when they are even and level. When adjoining
materials are not even and level, they must be held back a minimum of ½ inch for sealant
application.
- b.
The EPS insulation board shall be terminated a minimum of 8
inches
above finished grade.
- c.
Sealants
