Wall Flatness and Squareness
The wall area should be checked for flatness and squareness before any splashback dimensions are taken.
Areas requiring packing out should be identified and corrected. It is recommended to use double-sided tape
as the method for packing out low sections of the wall. Tolerance for wall flatness is + /- 2mm/m vertically and
horizontally. Wall squareness is +/- 5º from a right angle (90°).
Dimensional measurement
Wall dimensions should be taken after wall preparation and/or corrections are complete. Measurements are to be to
the nearest 1mm, with allowance for diagonal variations. Check all measurements before transferring to the Laminex
Metaline Splashbacks surface. (Refer to Fabrication section for the most suitable method of cutting to size).
Dimensions will depend on the selected method of installation (viz. folded vs butt joined method).
Taping
Double-sided tape must be used to provide initial adhesion during the installation process. Laminex recommends
the use of 12.5mm minimum width, 3M VHB 4991or 3M Scotchtape 4008 tape to assist in the installation process.
The double-sided tape performs 2 key functions:
• Provides initial adhesion of panel to the wall during silicone cure.
• Allows adjustment of the wall flatness to pack the panel out for plumb fit.
Double-sided tape should be
applied vertically, spaced every
450mm across the width of the
panel, and down the full length
of the wall.
Do not remove
the protective strip from the
tape until after the dry fit of
the panel.
