SINGLE COURSING - G&R Cedar
1
1. Apply 15-30 lb. felt building paper over sheathing. 2. Double the first course at base of wall - use dry low grade #3 or #4 shingles or other acceptable undercoursing for starter course. 3. Space shingles slightly apart (1/8” - 1/4”) to allow for expansion and to prevent bucklings. 4. Offset joints 1 1/2 ” from adjacent courses. 5. Drive nails approx. 1 inch abbove butt line of succeeding course for concealed nailing. 6. For shingles up to 8” wide, two nails in each shingle are placed 3/4” from each edge. For wider shingles a third nail should be driven in the centre. 7. Use only 1 1/4 ” - 1 1/2 ” stainless steel nails (type 304 or 316). 1. Same as SINGLE COURSING 2. Two layers of dry undercoursing recommended for starter course, then the outer course. 3. Each succeeding course requires dry undercoursing to be applied before outer course is applied. Outer courses applied 1 inch lower than undercoursing. 4. Face nail outer course shingles with two casing-type nails (as in #7 above), driven about 2 inches above the butt line, 3/4 inch from edge plus additional nails every 4 inches on wider shingles (as in #6 above) NOTE: The appearance of discoloration (extractive bleeding) on surface of light colored stains or paints is neither a fault of stain, paint or wood, but rather it is an indication of the presence of moisture in the walls. NOTE: INSTALL BEST FACE OUT 1. Outside corners can be either: a) laced; b) shingles butted against corner boards; c) mitered 2. Insider corners: Butt shingles against square wood strip on inside corner NOTE: FACTORY PRIMED COATING IS NOT A SEALANT. THE USE OF WATER BASED PAINTS AND OR STAINS ON CEDAR SHINGLES, NATURAL OR PRIMED, MAY CAUSE EXTRACTIVE BLEEDING DURING THE DRYING PRO- CESS.
