How do you make a raked mortar joint? |



A raked mortar joint is the one with a slight slope on the top. This makes it easier to remove when you want to change your bricks. A bricklayer will be able to make and install them faster because they don’t have to keep trying different angles, which can take time. The video below explains how this process works in greater detail than I ever could!

A raked mortar joint is a type of construction that uses a series of vertical joints in the wall. The joint is created by filling the space between two masonry units with mortar, then troweling it level and pushing it into place.

Insert the nail head into the vertical junction you created on the rake. To make a raked joint, pull the board straight down. Remove any mortar that has come loose from the joint. Repeat for all of the vertical joints, then move the rake from side to side to complete all of the horizontal joints.

So, what exactly is a raked mortar joint?

The mortar in raked joints is not compacted against the joint surfaces. The front part of the mortar joint is scraped away instead. Raking away the mortar may create gaps in the head and bed joints, allowing more water to penetrate.

What’s the best way to clean a mortar joint? With a hard brush, scrub the mortar from the brickwork. Any high places near the joint edges are also knocked down and smoothed away. Clean dry mortar from the bricks with a stiff-bristle brush once the joints have set up (approximately 30 minutes after tooling) (Photo 9).

Repointing vs. tuckpointing: what’s the difference?

The Difference Between Repointing & Tuckpointing

The distinction is that one is used to repair structural damage while the other is utilized for cosmetic purposes. The technique of repointing restores the structural integrity of mortar joints.

For various reasons, Type O mortar, also known as high-lime mortar, is the optimum choice for repointing. It is a softer mortar with a low compressive strength of 350 psi.
