This general technique discussed in the video applies to any Owens Corning Stone installation with a 1/2″ mortar joint.
First, if your project has outside corners, begin install with those. All corner pieces have a long leg and a short leg; always alternate the direction in which the pieces face.
Press each piece into mortar bed firmly enough to squeeze some mortar out around the edges of piece to ensure a good bond. Be sure mortar joint always stays consistent in width. When using a ledge style project, make sure you check to make sure each is level and plumb.
If the wall has windows or doors, the stones should be applied around any openings first before rest of wall. Once corners and trims are in place, you can continue by laying flat pieces.
Tip: Windows and doors you can use special trim stones or sill pieces for a more sophisticated design.
Lay bottom stones first, and then fill in towards top. Use small pieces to fill in voids. You may have to cut or trim pieces to achieve or proper fit. You can feather edges with a hatchet or nippers. When using a wet saw, be sure to clean saw after cutting. For best results, coat the cut edges with mortar – if possible, position cut edges ‘up’ when they will be above eye level, and position the cut edges ‘down’ when the stone will be below eye level.
Tip: For inside corners, place stones so they knit in an alternating pattern.
Fill joints using your grout bag. When mortar is thumbprint hard, you can press and rake out excess mortar for a clean unified look. The finished job should be groomed or brush to remove excess mortar.
