Fiber Cement Finish Panels Installation
Fiber Cement panels are available in vertical siding and smooth styles. Smooth Fiber Cement is designed to
have a Stucco finish applied in the field or to be painted. Vertical siding style is meant to be field painted to
more closely match existing construction. See instructions below on painting Fiber Cement.
Inspect all panels as outlined on page 1. All door sections and Buck Openings on Fiber Cement Walk-Ins are
constructed using W.A. Brown traditional metal finishes.
Set out panels as outlined on page 1. Fiber Cement panels have a gasket on one side (the inside) and require
caulking at the joint between the outside skins. Use only the approved ChemCaulk 2000 sealant manufactured by
Bostik to seal these joints. This construction grade sealant is specifically designed for fiber cement and Hardie
Board materials. If the include caulk option was chosen at the time of quotation and purchase, ample material
will be supplied with the shipment. If not, this material can be purchased locally.
Caulk all wall to wall, wall to ceiling and wall to floor or floor screed joints with a .25” or 1/4” bead of material before
locking the panels together. This will assure a good seal. Complete this process with the installation of each panel.
Only the exterior fiber cement skins need to be caulked. No caulking is required on the interior gasketed surfaces.
Painting Fiber Cement
Flashing for Fiber Cement coolers and freezers will be factory primed, and will require on site final painting. Door
sections and the door leaf can be primed at the factory for an optional charge if noted at time of order entry.
If you have not ordered factory priming, it can be accomplished on site. Latex paint is suitable for Fiber Cement,
however it may not adhere properly to certain vinyl trim pieces.
After your Fiber Cement Walk-In has been fully assembled, it will be necessary to apply a finished coat of paint to
all exposed surfaces. It is recommended that primed siding must be painted within 180 days of installation. Apply
a high-quality, 100% acrylic paint. Solid or semi-transparent stains should be used only on unprimed Fiber Cement.
Never use oil-based paints on Fiber Cement. For further questions on priming and painting Fiber Cement, feel free
to contact W. A. Brown, or call Duck Back, Woodperfect Fiber Cement Coating at 800-825-5382. Ask about their
water based, alkaline resistant, acrylic Latex primer and paint.
