Tuckpointing & Repointing

Mason raking failed mortar joints in a dark brick wall with the Arbortech ALLSAW

Cut the joint,keep the brick

Everything you need to cut out failed mortar joints cleanly — square, consistent depth, no chipped arrises and no clouds of spinning dust.

Repointing starts with a clean cut

Raking out with an angle grinder is fast but brutal — overcut corners, damaged brick faces and silica dust thrown across the site. Tuckpointing is finish work, and the prep decides the result.

The ALLSAW's oscillating twin blades cut mortar out like a hand saw with power behind it: square ends, controlled depth, minimal vibration through the wall and dust that stays at the blade instead of in the air.

Technique

Rake joints without kickback

The ALLSAW's counter-oscillating blades don't spin, so there's no kickback and no gouging when you track along a bed joint. Cut to a consistent depth, square up the ends of each joint and leave clean faces ready for new mortar.

Trade insight

The new mortar is only as good as the joint you cut.

Rushed raking shows through every finished joint. Square ends, consistent depth and undamaged brick faces are what separate repointing from patching.

The process

Three steps to crisp joints

The same sequence works on a single elevation or a whole facade.

  1. Step 1

    Cut out the joint

    Track the tuckpointing blade along bed and head joints to a consistent depth — typically twice the joint width — squaring the ends as you go.

  2. Step 2

    Clean & prep

    Brush and flush loose material from the joint, then dampen the substrate so the wall doesn't pull moisture out of the new mortar.

  3. Step 3

    Repoint & finish

    Pack mortar in firm layers and strike the profile to match the original work — the clean cut is what makes the finish crisp.
