4. Installation: Fabrication and Assembly Recommendations
Fabrication should follow approved methods. Assembled pieces should meet the specifications of
KCMA (Kitchen Cabinetmakers Manufacturers Association), ANSI A-161.2-1998 (revised), and
“Architectural Woodwork Quality Standards, Guide Specifications and Quality Certification Program”
guidelines of the Architectural Woodwork Institute where applicable.
Wilsonart laminates must be bonded to a substrate of reliable quality, such as particleboard, medium
density fiberboard or plywood with one A-face. High-pressure laminate, plaster, concrete and
gypsum board should not be considered suitable substrates. Basic Types laminate may not be used
as structural members.
Bond with adhesives and follow the techniques recommended by the adhesive manufacturer.
Recommended adhesives are permanent types, such as urea and polyvinyl acetate (PVA), and
contact types. Wilsonart adhesives are recommended for most bonding conditions.
To avoid stress cracking, do not use square-cut inside corners. All inside corners should have a
minimum of 1/8” (3.175mm) radius and all edges should be routed smooth.
Drill oversized holes for screws or bolts. Screws or bolts should be slightly countersunk into the face
side of a laminate-clad substrate.
Take care to ensure an appropriate acclimation between the laminate and the substrate prior to
fabrication. The face and backing laminates and the substrate should be conditioned in the same
environment for 48 hours before fabrication.
Recommended conditioning temperature is about 75°F (24°C). Laminates should be conditioned at
45% to 55% relative humidity.
With postforming machinery, Wilsonart 335 and 350 will postform at a nominal sheet temperature
range of 325°F to 338°F (163°C to 170°C) in 20 ± 5 seconds.
Carbide-tipped saw and router blades should be used for cutting. High tool speed and low feed speed
are advisable. Cutting blades should be kept sharp. Use a hold-down to prevent any vibration.
