- 1
Never face-nail siding — always fasten through the nailing hem only
- 2
Leave 1/32" clearance between fastener head and nailing hem (panels must move freely)
- 3
Leave 1/4" expansion gap at all openings, corners, and trim junctions — increase to 3/8" in cold climates or below 40°F
- 4
Do not caulk between panels, between siding and J-channel, or between siding and corner trim — panels must expand and contract freely
- 5
When installing a panel, push up from the bottom until the LineLock™ system is fully engaged with the piece below, then fasten without stretching
- 6
Drive fasteners straight and level — nailing at an angle distorts panels and causes buckling
- 7
When finishing top of wall, perforate cut edge with snap-lock punch approximately every 8" so tabs face outward
- 8
Overlap horizontal siding panels approximately 1" — excessive overlap restricts free movement and can cause product failure
- 9
Stagger end lap joints so no two courses are vertically aligned unless separated by at least 3 courses
- 10
Always overlap joints away from entrances and away from the point of greatest traffic
- 11
Check every fifth or sixth course for horizontal alignment; also check alignment with adjoining walls
- 12
Use fasteners long enough to penetrate a minimum of 3/4" into the nailable base
- 13
Install starter trim level — it sets the alignment for all subsequent courses; nail at 10" intervals
- 14
Keep starter strip ends at least 1/4" apart from corner posts and J-channels to allow for expansion
- 15
Apply undersill trim under all windows; use snap-lock punch on cut panel edges every 6" for secure fit
- 16
Apply drip cap above all windows and doors before installing siding over them
- 17
Do not install over foil-backed foam insulation — voids Kaycan warranty
- 18
Asbestos siding is a regulated material — contact the appropriate environmental agency before residing over it
- 19
Check all local building codes and fire regulations before installation; local code requirements always take precedence
- 20
In new construction, avoid green lumber as underlayment — siding can only be as straight as what lies beneath it
