Panel cutting must be done on a flat surface.

The sandwich panel should never be used as a work surface for cutting another sandwich panel or other element. The remains of this cut can stay on the panel and lead to oxidation on the surface of the panel.

Masterpanel advises against cutting panels on site and cannot guarantee the performance of panels cut on site. During the cutting of the panel, its technical characteristics are modified, as well as, stresses and vibrations being transmitted, which can lead to long-term defects on the surface, such as blistering. If the client requires the cutting of the panel on site, it is advisable to follow the following steps to avoid damaging the panel surface:

1. Place the panel on a flat surface.
2. Clean the area to be cut.
3. Determine the line of the cut.
4. Placing adhesive tape on the line of the cut is recommended in order to protect the surface and avoid scratches on it. Such tape must be removed prior to panel installation.
5. Cut along the previously determined line.
6. Clean the cutting area of any impurities, chips, etc.
7. Polish the edges removing burrs.

If the width to be cut is less than 50% of the panel width, it is recommended to cut the full thickness of the panel and remove the cut part before installing the panel.

When the width to be cut is greater than 50% of the width of the panel or when areas that may compromise the stability of the panel are removed before installation, it is recommended to proceed as follows:

• First, it is recommended to cut the inner face sheet and the foam to a depth of about 5-6 mm.
• Then turn the panel over and cut the veneer on the outer side and the foam to a depth of about 5-6 mm.
• Without removing the cut area, install the panel, fixing it to the structure as it has been designed.
• Once installed, use a utility knife to cut the foam from the cut area and remove.

In any case, after cutting the panel, the core should never be exposed. Therefore, the core must be protected by sealing systems, collars, finials, etc.
