Building an insulated concrete form (ICF) house or building allows you to apply many ICF exterior finishes: fiber cement boards, stucco, masonry veneers, panel siding, and wood or vinyl siding. If you can apply the finish on a wood-frame structure, you can use it as an ICF exterior finish. However, an ICF wall provides significantly more strength and durability than a wood-framed wall. Your choice of an ICF exterior finish should not just consider cost, personal preferences, and local styles. Other vital factors like ease of installation and climate should also impact your decision for an ICF exterior finish.
The effectiveness of the exterior finish depends entirely on installing it correctly and professionally. Therefore, ICF exterior finishings that install simply and efficiently will improve your chances of the long-term durability of the wall system. Fortunately, Sto ICF Finish Systems offer a single-source solution for creating an ICF exterior wall and finishing solution, to ensure its appealing, long-lasting curb appeal.
Sto Offers the Best ICF Exterior Finishing Solutions
Sto’s specialized finish systems offer an ICF above-grade wall assembly in three finish system options for new construction. Each option offers long-lasting protection, to provide endless exterior finishing solutions with an expansive range of color and texture choices.
Sto ICF Exterior Finishing Options
Sto recommends the finishing option based on the shape of the wall, the ties location on the foam, and the need for extra insulation and a harder finishing surface.
We recommend Option 1, a multiple-layer decorative and protective finish system, for straight, flat ICF walls requiring little leveling, with ties embedded at least 1/2 inch inside the ICF form. Option 1 utilizes a Sto base coat, an optional Sto primer, reinforcing mesh, and a Sto finish.
Sto ICF Coating System provides,
- Direct application on exterior above-grade ICF wall construction
- Barrier wall construction drainage
- Energy efficiency with the continuous exterior insulation of the ICF
- Air and moisture protection with ICF Barrier wall construction with a concrete air barrier
- The reinforcing mesh embedded in the base coat provides standard impact resistance.
Option 2: StoTherm® ci Cladding Systems
We recommend Option 2 for non-straight and non-flat walls requiring leveling and ties less than 1/2 inch inside the foam. Option 2 also works best if you need additional continuous insulation on the building’s exterior. The insulation will help promote energy efficiency and meet the current building codes of your climate zone.
StoTherm® ci cladding systems add continuous insulation to the exterior and include reinforcing mesh, an optional Sto Primer, and one of the many Sto textured finishes to create a sustainable, high-performance wall cladding. The unique and durable system sustains maximum curb appeal and saves money through lower energy bills.
StoTherm® ci Cladding Systems offer,
- StoTherm® ci Cladding Systems apply on the exterior above-grade ICF wall for new construction
- Drainage wall construction, when properly integrated with flashing
- Premium energy efficiency due to the addition of exterior CI to the ICF
- Air and moisture protection with ICF backup wall construction with StoTherm® continuous insulation system
- The reinforcing mesh embedded in the base coat provides medium impact resistance.
Option 3: Sto ICF – Stucco System
We recommend the Stucco Coating System if you need a harder finishing surface. StoPowerwall Stucco includes stucco, a metal lath, Sto Primer, and a Sto finish. The combination ensures the long-term durability and strength of traditional stucco with StoGuard moisture protection and Sto high-performance with finishes and coatings that keep moisture out. The system also provides a variety of design options.
Sto ICF Stucco System provides,
- Sto ICF Stucco System applies on exterior above-grade ICF new wall construction with metal lath and paper backing anchored into ICF web ties or concrete.
- Limited drainage when integrated adequately with flashing
- High energy efficiency due to the continuous insulation of the ICF
- Moisture and air protection with the ICF backup wall construction and code-compliant WRB with StoPowerwall® Stucco Finish System
