Application Notes:
• Good workmanship is crucial to the integrity of any sidewall system. Installers should read the CSSB Installation Manual carefully and ensure that they follow proper workmanship practices.
• Certi-label Western Cedar shingles and shakes are applied on walls differently than on roofs. The major difference is in permissible weather exposures. On walls, the maximum weather exposure is greater than it is on roofs.
• A given area of wall will require less material than the same area of roof.

Finishing Cedar Shakes:
• Use oil-based stains only. To hasten the weathering process, apply a bleaching oil finish.
• Generally finish products immediately after installation, provided that the moisture content is appropriate for both the finish product being used and your locale. If the finish is not applied promptly, adhesion can be compromised (unless additional surface preparation is undertaken).
• If you have installed a natural product (unfinished), apply your finish before rain and other moisture are absorbed. Ensure that high humidity concerns have been accounted for.
• In all instances, drying time varies from region to region. Excessive moisture will limit finish adhesion.
• If you clean the surface prior to finishing, ensure that it is allowed to dry to the manufacturer's recommended moisture content level before applying a new finish.

Nails:
• Each Certi-label Western Cedar shingle or shake should be applied with two fasteners.
• Nails must be stainless steel Type 316 in locations within fifteen (15) miles of salt water (ref. Stainless Steel Industry of North America, Washington DC, www.ssina.com).
• For locations outside the salt water zone, nails must be stainless steel Type 304, Type 316, or hot-dipped zinc-coated galvanized conforming to a coating weight of ASTM A 153 Class D (1.0 oz/ft2).
• Stainless steel nails, although more expensive, offer the highest degree of corrosion resistance.
• Contact the nail manufacturer for further information to ensure the nails used comply with listed requirements and are correct for your application.
• Minimum nail lengths are shown in the fastener chart located in the CSSB Shingles Installation Guide.
• In double course applications, the exposed Certi-label Western Cedar shingle or shake should be face-nailed with two nails (as above), driven 2" above the butt line, and 3/4" from each edge.
• Certi-label Western Cedar shingles wider than 10" require 2 additional nails driven approximately 1" apart near the center of the shingle.
**Please Note: Some nail manufacturers offer nails specifically for wood shake or shingle sidewall application. Contact the nail manufacturer for further information to ensure the fasteners used comply with listed requirements and are correct for your application.

Staples:
• If you choose to use staples, they must be stainless steel Type 316 in locations within fifteen (15) miles of salt water.
• For locations outside of the salt water zone, stainless steel staples Type 304 or Type 316 must be used.
• Two staples should be driven per Certi-label Western Cedar shingle or shake with the staple crowns 7/16" minimum horizontal, maximum 3/4" horizontal, to the Certi-label Western Cedar shingle or shake butt.
• Staples are driven in the same location as nails relative to the sides and overlapping butt line.
• Certi-label Western Cedar shingles wider than 10" require 2 additional staples driven approximately 1" apart near the center of the shingle.
• Fasteners should be long enough to penetrate into the sheathing at least 3/4" or all the way through, and driven flush with the surface of the Certi-label Western Cedar shingle or shake.
• In all applications, staples shall be concealed by the course above.
• DO NOT USE ELECTRO-GALVANIZED (EG) FASTENERS. Ensure the fasteners used comply with listed requirements.
• For aesthetic reasons, nails are preferred in sidewall application using exposed fasteners.
