What Is Decoplast? A Contractor's Guide to the EIFS Finish System
Decoplast is a line of EIFS (exterior insulation and finish system) materials — adhesives, base coats, primers, and textured finish coats — manufactured by Greenmaker Industries. It is the decorative, weather-resistant outer portion of a synthetic-stucco wall assembly. Contractors choose it for its range of textures, elastomeric crack-bridging finishes, and manufacturer warranties that run from 5 to 20 years. New England Building Supply Corp stocks Decoplast finish and Greenmaker base coats in Meriden, CT.
What exactly is Decoplast?
Decoplast is a brand of EIFS materials — paints, primers, textured finishes, adhesives, and base coats — made by Greenmaker Industries.
It is not a single product but a system of coatings that together form the outer, visible portion of an EIFS (also called synthetic stucco) wall. According to the manufacturer, Decoplast products have been applied on more than a quarter-billion square feet of wall surface across North America, South America, Europe, Asia, and the Caribbean. In practice, a contractor reaches for Decoplast when they need the base coat that embeds the reinforcing mesh and the finish coat that gives the wall its color and texture.
How does Decoplast fit into a full EIFS wall?
Decoplast supplies the base coat, optional primer, and finish coat — the layers applied over the foam insulation and mesh.
An EIFS wall is built up in layers over the building's sheathing. As the EIFS Industry Members Association (EIMA) describes it, the assembly typically includes a water-resistive barrier, expanded polystyrene (EPS) insulation board, a base coat with embedded alkali-resistant fiberglass mesh, an optional primer, and a finish coat. Decoplast's own DDARS drainage system, for example, consists of a fluid-applied air and water-resistive barrier, base coat, optional primer coat, adhesively applied EPS insulation board, a second base coat with reinforcing mesh, and the finish coat. The diagram above shows where each layer sits.
Why is the base coat and mesh layer so important?
The base-coat-plus-mesh layer is what gives an EIFS wall its impact resistance and crack control. The fiberglass mesh is embedded into wet base coat so that, once cured, no mesh is visible — that embedded reinforcement is what lets the relatively thin finish flex without cracking. NEBSC stocks both Greenmaker GM Standard Base Coat and 4.8 oz EIFS reinforcing mesh for exactly this layer.
What finish textures and options does Decoplast offer?
Decoplast finishes come in multiple textures and include elastomeric options that bridge hairline cracks.
The Decoplast Decolastic Top Coat is an elastomeric, acrylic-based decorative coating that weatherproofs and bridges hairline cracks over concrete, stucco, EIFS, masonry, or previously coated surfaces. The Decolastic 250 is a water-based textured finish formulated to be tough, durable, flexible, and breathable. The Decoplast finish coat NEBSC carries comes in a white base with four texture choices, which can be tinted to a project's color. The "breathable" property matters on exterior walls because it lets water vapor escape rather than trapping moisture behind the coating.
What warranty does Decoplast carry?
Greenmaker offers labor-and-material warranties on Decoplast systems ranging from 5 to 20 years.
The exact term depends on the specific system and how it is installed, so the warranty length should be confirmed for your assembly with the manufacturer's current documentation. [Unverified for any specific project: warranty coverage always depends on correct installation and the system specified — confirm the current terms with Greenmaker before relying on a number.]

Is Decoplast the same as stucco?
Not exactly. Decoplast is used in EIFS, often called "synthetic stucco." Traditional stucco is a cement-based plaster applied in coats over lath, while EIFS is a multi-layer system built over foam insulation with an acrylic-based finish. They look similar but are different assemblies.
Who makes Decoplast?
Decoplast is manufactured by Greenmaker Industries, which produces EIFS paints, primers, textured finishes, plasters, adhesives, and base coats.
Can Decoplast finish go over existing stucco or masonry?
The Decolastic elastomeric top coat is designed for use over prepared concrete, stucco, EIFS, masonry, or previously acrylic-coated surfaces. Surface preparation requirements vary, so follow the product data sheet for the specific finish.
