Even though EPS Cement Sandwich Wall Panel arrives at your site in standard sizes, you will often need to cut custom openings for doors, windows or electrical outlets during installation. The easiest tool for cutting a standard EPS Cement Sandwich Wall Panel is a diamond-tipped circular saw, which can slice through the cement outer layer and EPS core smoothly without creating large cracks. For small cuts or notches, a hand-held electric jigsaw with a carbide blade works perfectly, especially for cutting out small openings for electrical boxes. Before you cut the panel, always mark your cut lines clearly with a pencil and a straight edge, and use a clamp to secure the panel to a work table to stop it from moving during cutting. After you finish cutting the EPS Cement Sandwich Wall Panel, use a rough sanding block to smooth down any sharp edges or loose cement dust on the cut surface. Never use a regular wood saw to cut the panel, as it will dull the blade very quickly and leave ragged, uneven edges that are hard to seal later. With the right tools, you can make any custom shape you need from a standard panel in just a few minutes.
