Stucco Types: All That You Need to Know from Types to Paint

Stucco systems vary in appearance, insulation value, flexibility, and maintenance. The best choice depends on the existing wall, building design, desired finish, and budget.

We inspect your property, explain the practical options, and recommend a system suited to Ottawa’s climate.

​

Main Stucco Systems

The two main categories are traditional cement stucco and EIFS or acrylic finish systems.

• Traditional Stucco

• Synthetic Stucco

​

Traditional Stucco

Traditional stucco is a cement-based exterior system applied over properly prepared lath and base coats. It provides a durable, impact-resistant finish with several texture options.

Correct preparation, flashing, reinforcement, control joints, and curing are essential for a long-lasting installation.

​

EIFS & Acrylic Finishes

EIFS combines exterior insulation with reinforced base coat, fiberglass mesh, and an acrylic finish. Acrylic finishes are flexible, available in many colours, and commonly used on both EIFS and suitable base-coat systems.

A complete EIFS installation requires the correct insulation, adhesives or fasteners, reinforced mesh, base coat, details, and finish coat according to the selected system.

 

Lath & Reinforcement

Lath and reinforcement help support cement-based stucco and control cracking. The correct product and installation method depend on the wall assembly and project specifications.

​

Three-Coat Stucco Lath

Three-coat stucco lath is designed for traditional cement stucco assemblies and must be installed with the required overlaps, fasteners, clearances, and accessories.

Furred lath creates space for the base coat to fully embed around the reinforcement.

​

​

One-Coat Stucco Lath

One-coat lath is used only where an approved one-coat system and wall assembly call for it.

​

High-Rib Lath

High-rib lath provides added stiffness for specific plaster and soffit applications.

​

​

Expanded Metal Lath

Expanded metal lath is commonly used for stucco, transitions, and repair areas when specified for the assembly.

 

Coatings Made for Stucco

Stucco should be coated with products designed for masonry and compatible with the existing system.

• Elastomeric

• Masonry

• Acrylic

Breathability, adhesion, water resistance, and flexibility must be considered before choosing a coating. We assess the surface and recommend a compatible product.

Popular Stucco Textures

Texture changes the character of the exterior. Popular choices include:

• Float or sand

• Dash

• Lace and skip

• English

• Santa Barbara
