Stucco
Stucco delivers textures and patterns in a variety of attractive looks and—mixed with added colored pigments—never needs to be painted. Stucco is incredibly strong and can last hundreds of years, adding value and character to a building. The Parex NuTech™ ACF is one such exterior coating system for application to cement board wall coverings and soffits.
The NuTech ACF (Knight's basis of design) has four components all applied onsite directly to PermaBase® cement board that is attached to the PanelTek system for moisture management and energy efficiency:
1) Cementitious acrylic base coat, approximately 1/16" thick
2) Fiberglass reinforcing mesh embedded in the base coat, over an additional strip of fiberglass mesh placed over cement board joints
3) Acrylic Primer
4) Acrylic or elastomeric textured, colored finish
Advantages to NuTech Stucco with the Knight Wall Stofix PlasterTrack:
- Faster overall construction schedule due to very short cycle times versus conventional stucco. An average of 4 day cycles from start to finish on staged installs versus an upwards of 20+ day cycles for conventional stucco on staged installs.
• Day 1: Install PanelTek
• Day 2: Install Cement Board with mesh & base coat at joints
• Day 3: Base Coat with Fiberglass mesh
• ~24 hours later: Finish coat - PanelTek system will help eliminate “ghosting” or “telegraphing” often seen on traditional stucco finishes due to the limited amount of thermal bridging compared to typical framing/furring members.
- Limited amount of vertical and horizontal expansion joints required versus traditional stucco and EFIS due to the pliability of materials.
- Better resistance to higher wind loading versus EFIS while still maintaining the thermal advantages offered by EFIS due to the potential use of up to 6” of exterior insulation.
- PanelTek system allows for a quick and precisely plumb finished wall without the use of thousands of shims equating to labor and material savings.
- Seamlessly transitions to other cladding options mounted to Knight Wall Systems rain screen attachments (i.e. brick panels, metal panels, etc.) See website for guideline details.
- Vented rain screen cavity to help resist mold and prevent water ingress
- Cement board creates an extremely durable cladding surface
- Ideal for renovations
