| − | #Install cedar shims at the bottom of the frame. The shims will help hold the panel in place, and they will ensure an even placement of the panel in the space. The shims should be about 1/2” (1.27cm) wide and long enough to easily remove once the first round of mortar sets.<ref | + | #Install cedar shims at the bottom of the frame.

It should ideally have a consistency close to bread dough, which will stop the panel from floating in the space as its sets.<ref | + | #Mix small batches of mortar.

| − | #Apply caulk to seal the top of the window. Applying mortar at the top gap of the window can produce downward pressure as it sets that can compress and crack the glass. Let the mortar set for a full twenty-hour hours, then fill the entire gap with 100% silicone caulking.<ref | + | #Apply caulk to seal the top of the window.
