How do I design the corners and edges?

Slate-Lite can generally be laid butt-to-butt so that you simply push the stone slabs together.
If you would prefer to use finishing profile strips (especially for the outer edges of the building), we have finishing strips in several colors in our portfolio that perfectly match the overall thickness of Slate-Lite.
As the natural stone surface of Slate-Lite is rough and therefore there are slight differences in height due to the stone structures and grains, we recommend the use of profile strips in the façade area.
