5.3 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°).
5.4 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).
5.5 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 4991 or
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.
Figure 9
outlines the correct double-sided tape installation method.
