Faux joints for faux stones
Joints are scored with a speed square. Here, the square is held on edge to leave a rough, mortar like joint.
The square is held flat for a smooth joint. Also the speed square marks off a dark line accenting the joint.
On these faux granite blocks, the brown coat was scored first creating a deep joint. The finish is scored with a cheap concrete groover, making a nice dark joint.
Joints are made on this faux brownstone water table sill by taping the brown coat, and pulling off the tape when the mortar sets up..
