jointing tool การใช้

Joints are tooled with a rolling jointing tool prior to curing or saw cut after curing.
Use a jointing tool, sometimes called a groover, to cut control joints ( these will eliminate unsightly random cracks ) at six-foot intervals across the slab.
For repointing you will need tools like a cold chisel, which should be narrower than the mortar joint; a two-pound sledgehammer, a mason's trowel, a pointing tool and a jointing tool.
Before the mortar sets up completely smooth off and tool the surface of the new mortar joint to match the existing mortar joints by using either a special brick jointing tool, or the point of a small triangular trowel.
