E. APPLICATION: Haida Bevel siding is applied the same as other bevel sidings using all of the above recommendations. Haida Skirl is applied in a similar manner to most Bevel sidings with one exception - the gauging of the rows is done from the top edge due to the irregular line formed by the bottom wavy edge.
To commence applying Haida Skirl siding do the following:
- Determine the overall height to be covered by the siding.
- Mark this height along the length of a measuring stick (1x2) and divide it into spaces representing the courses of siding. First mark off a space 6" down from the top end for 10" Haida Skirl and 8" down from the top for 12" Haida Skirl. The remaining distance can now be divided into equal spaces depending upon whether you use the minimum 1-1/2" overlap or the recommended 2" overlap. i.e.: For the 2" overlap this would be 7 1/2" exposure for the 10" Skirl and 9 1/2" exposure for the 12" Skirl.
- It is recommended that building paper be used over sheathing - even styro-form. Apply one 36" course along the base to be covered by the siding.
- The first course of the siding does not lap over a preceding piece and so fails to cant outward at the proper angle. To adjust this a wood starter strip should be placed around the base at the point where the lower edge of the first course of siding will be placed.
- Using the measuring stick proceed to mark out at 36" intervals the position of the courses.
- Apply the siding with the top edge lining up along these marks. This will automatically provide the correct lap along the irregular lower edge.
- The corners for the the best effect should be mitered. There will be variances in depth where the skirled ends of the 2 pieces meet. These can be matched by sawing or chiseling one piece to match the other. Another popular method of handling corners is to butt up to wood corner strips.
- Where variances in depth occur at butt joints along the straight sections adjust the wave or skirl to blend by chiseling - see diagram #3
- Where possible select pieces that blend naturally.
- Haida Skirl is manufactured to closely resemble the natural wane of Cedar boards cut from a log. There will be pieces that are more wane or wavey than others depending upon the knot structure. Care should be taken to select siding boards so that there is pleasing mixture of boards that are not heavily skirled with those that are. This mixture adds to the esthetic and natural appearance of the siding.
Haida products are produced to the highest standards. The siding is kiln dried and knots that may require it are "permi-fused" to the surrounding wood to ensure that they do not fall out. The product can, however, receive some damage from the time it leaves the mill until it reaches the job site. Should this happen be sure to trim out any imperfections before application. These may be checks or spit-ends. If any end-trimming is required do not leave a large knot, over 1" in diameter, within 3" of the end of the piece. This can weaken the end of the siding and may lead to some end-splitting after application.
- It is especially critical that application over styro-form sheathing be perfect. We recommend that a breathing type building paper be used between the styro-foam and the siding. It is also recommended that 10" wide siding be used rather than 12".
