- You can use a variety different masonry jointers for slapping the joints depending on where they are located. They also give the joints an artistic look.
- New England is home to the convex jointer. The convex curve refers to the actual shape of the tool, not the mortar slick that it leaves behind.
- It is very common in Pennsylvania and the mid Atlantic region. The mortar will show a distinct groove from the jointer.
- Flat jointers are a standard type of jointer, and they’re common in most areas of the country. Mark prefers to hold the flat-joiner at an angle so water can slide down the joint onto the brick beneath it. This minimizes the chance of water getting behind bricks.
- There are many names for a rat’s tail jointer, but they all have different sizes depending on the part you use to slick mortar. This jointer is especially useful for stonework where the gaps between masonry can vary from one stone to the next.
- The skate jointer can quickly fill in the gaps left by masonry jointers. The masonry nail at the center sets a consistent depth which can be pulled along the mortar with the back end of a jointer.
- Concave jointers have the opposite appearance to convex joints. It is more common in South Africa and leaves more mortar exposed at the joints.
