Fix the stone in the wanted sample on the surface beside the wall. You may need to cut the actual stone to build the project before the design differs.
Wash the stones and concrete wall.
Put together your plaster till it appears, such as peanut butter.
Use ½ inch of plaster to the bottom of the stone and post it tightly to the concrete wall.
Force closely, and any plaster gets the sides.
Separate extra plaster at the border beside it fixes.
As you design many stones, ensure the connections will be regular in shape.
Once completed, use the concrete plaster.
Apply a piece of plaster equipment to design a good wash plaster border.
