Introduction to Different Kinds of Repointing

Posted by Sean Butler on August 13th, 2019

Repointing is the process of replacing old and crumbling mortar with fresh material. This can help improve the appearance of the wall, extend its lifespan, and improve its structural integrity. An experienced pointing professional knows how to remove old material cleanly and add new mortar without leaving behind any gaps in the wall. Professionals can use a wide range of pointing techniques based on the client's requirements. These pointing techniques are described below:

1. Flush pointing

Flush pointing is the most commonly used and basic brick repointing technique. It involves pushing the mortar into the cleared gaps between bricks and pressing the material in until it is flush against the wall surface. This creates a smooth wall that doesn't have any indentations or definition. Flush pointing is popular because it is easy to maintain and durable. There's no room for dust, debris, or water to settle, which can help keep the wall intact for a long time. However, this isn't the prettiest of finishes and homeowners who want their walls to have some character often shy away from it.

2. Recessed pointing

Recessed pointing is a popular technique with clients who want their brick walls to have some texture and dimension. The pointing expert pushes the mortar into the gap using a special tool until it is around 5mm deeper than the surface of the bricks. The mortar surface is flat and parallel to the brick surface, giving the wall an even but textured appearance. This design is visually appealing and quite elegant, but it requires some time and effort.

3. Struck pointing

Struck pointing is a combination of a flush and recessed pointing. The mortar is pushed back at a smooth angle until the bottom is flush against the brick wall and the top is 10mm into the wall. This creates a slanted surface that helps with water drainage. You get a better dimension and texture while avoiding water and dust accumulation. Struck pointing is the best of both worlds.

4. Grooved-in pointing

Grooved-in pointing is similar to flush pointing and struck pointing. The mortar is pushed back using a special tool until its surface is concave. The top and bottom are flush against the brick surface while the middle is curved inward like a bowl. This creates a soft textured surface and gives the wall an elegant appearance. The design doesn't trap any water or much debris, which makes it suitable for all kinds of buildings.

5. V-pointing

This technique is similar to the grooved-in style, but with a v-shaped groove instead of a concave groove. The top and bottom portion of the pointing is flush against the surface but the mortar has a sharp and smooth v-groove in the middle, giving the wall a very distinctive appearance.

Other pointing techniques include weathered pointing, tuckpointing, and beaded pointing. All of these techniques give different results and finishes.
