Skate Wheel Mortar Raker
Art. Nr: 301110
Size: 7"

A two-wheel mortar joint raker for brick and block work. It does two jobs: cutting old, loose or deteriorated mortar out of existing joints so the wall can be repointed, and cutting a raked (recessed) joint profile on newly laid work where that profile is specified.

Core Features

  • Two skate wheels, one cutting pin. The wheels run on the brick faces flanking the joint, not in the joint, and the cutting pin between them is the part that actually cuts.
  • Depth is set by the tool, not by the operator's hand. Because the wheels ride on the brick, the pin projection you set is the depth carried from one end of the course to the other. Depth consistency stops being a skill question.
  • Adjustable pin projection. The pin is set with a screw in the body, so one tool covers a range of rake depths instead of one fixed depth. The adjusting screw is on the top face of the body, and the pin protrudes between the two wheels.
  • Set the pin head against the mortar, not the point.
  • Rolling action instead of dragging. Both wheels carry the tool along the wall, so long horizontal runs do not depend on the operator holding a constant hand pressure and angle for the whole course.
  • Two applications from one tool. Joint renewal ahead of repointing on existing walls, and raked profile cutting on new work.
  • Nominal size: 7" for 301110 (≈178 mm). It is not a blade width; see Full Size Reference below.

Product Advantages

Depth consistency is mechanical, not manual. The single most useful property of this pattern is that the depth reference surface is the brick face, not the mason's wrist.

A hand raker or a screwdriver-and-line method reproduces depth only as well as the operator can hold it; here the wheels bridge the joint and hold the pin at a fixed projection for the length of the run. On a long course of facing brick, that is the difference between a joint line that reads straight from ten meters away and one that does not.

Less fatigue on long runs. The tool rolls rather than being dragged, so the effort is push force rather than sustained downward pressure. This matters most on large facades and long retaining walls, where the same joint has to be worked for many meters without the depth drifting.

Staged depth control instead of one deep pass. Because the projection is adjustable, the working method is to start shallow and step the pin deeper over successive passes until the joint reaches the specified depth. That avoids the tool snatching on hard aggregate and avoids over-cutting a joint you cannot put back.

Correct positioning against a jointer. A raker and a jointer are opposite operations, and buying one when you needed the other is easy to do. A raker removes mortar and leaves a recessed, uncompacted joint face.

A convex or V jointer compresses mortar into the joint, and compaction is what produces the profiles that best resist water penetration. On a repointing job you generally need both: this tool to cut the old mortar out, a convex or V jointer to tool the new mortar in.

How to Use

When to Use

Situation Use 301110? Why
Old mortar to be cut out before repointing Yes, primary application The tool's stated purpose is clearing loose or deteriorated mortar, paint and residue from existing joints
Raked profile specified on new brickwork, sheltered or interior Yes The wheels hold a constant profile depth along the course
Raked profile proposed on an exterior wall exposed to driving rain Review the specification first Raked joints are not recommended on exterior walls.
New mortar to be compacted and finished No, use a convex or V jointer Compacted concave, V and grapevine profiles are the ones that best resist water penetration
New mortar past thumbprint-hard (raked profile on new work) No No thumb impression means the new mortar is too hard to rake cleanly. This test does not apply to old mortar being cut out before repointing.
Concrete block (CMU) joints Case by case The wheels track on the relatively flat block face, but block joints are often wider than brick joints, and a deeply recessed block joint may not suit the wheel diameter. Trial one panel before committing.
Heritage brickwork in lime mortar Yes, with a trial area Lime mortar is softer than Portland cement mortar, so the timing and pin setting differ; test a small area first.

Basic Technique: Step by Step

Step Action Watch for
1 Check the mortar. On newly laid work, press a thumb into the mortar (thumbprint-hard test): a clear impression with no mortar sticking to the thumb means the joint is ready to be raked. Old, hardened mortar being cut out before repointing is expected to be hard and is not judged by this test. New work: mortar sticking to the thumb = still too soft, wait; no impression at all = too hard to rake cleanly. Old mortar: try a short section first; if the pin will not cut it, or the brick face is uneven, use a hand tool or a powered mortar saw.
2 Inspect the tool. Confirm both wheels rotate freely and without wobble, and that the pin is straight, undamaged and firmly clamped. A wheel that binds makes the tool skid and lose depth reference.
3 Set the pin projection. Slacken the adjusting screw, set the pin to a shallow projection below the wheel line, and re-tighten. Set shallow for the first pass: you can always go deeper, you cannot put mortar back.
4 Position the tool. Place both wheels on the brick faces flanking the joint, never in the joint, with the pin centered in the mortar. If a wheel drops into the joint the depth reference is lost and the tool will wander.
5 Cut with the head end of the pin. Work with the headed end of the pin bearing on the mortar, not the point. Leading with the point digs in and snatches.
6 Roll the tool along the joint in a smooth, continuous motion from one end of the course to the other. Do not pause mid-joint; a pause under load leaves a depth mark.
7 Step the depth up in stages. Re-set the pin deeper and repeat the pass until the joint reaches the specified depth, rather than reaching full depth in one pass. Hard aggregate in the mortar is the usual reason a single deep pass snatches.
8 Cut the vertical (perpend) joints first, then the horizontal (bed) joints. Debris from the vertical joints then does not fall into horizontal joints already cut. Follow the site specification if it states an order.
9 Brush out. Clear loose mortar debris from the cut joints with a stiff brush once the surface is hard enough to take it without smearing. Brushing while the mortar is still soft smears the face of the brick.

The Limits of a Raked Joint: Read Before Specifying

A raked joint is an appearance detail, not a weathering detail.

Raked joints are not recommended for exterior walls: the way the profile is formed does not compact the outer face of the mortar, and it leaves a horizontal ledge that collects water and can saturate the brickwork.

Where water penetration resistance governs, the profiles rated best are concave, V and grapevine, all of which are tooled, that is, compacted, rather than raked.

What this means for how you use 301110:

  • Use it for repointing preparation on any wall, exposed or sheltered. Cutting old mortar out is the application that is never in question.
  • Use it to cut raked profiles where appearance drives the detail: interior brickwork, sheltered elevations, feature panels.
  • Where the wall takes driving rain, cut the joint with this tool, then finish the new mortar with a convex or V jointer rather than leaving the raked face.

Large-Area Exterior Wall Raking and Repointing Preparation

This is the application the wheeled design exists for. On a long facade or retaining wall the joint has to be cut to the same depth for many meters, and the wheels supply that reference mechanically instead of asking the operator to hold it.

Work one full course at a time rather than jumping between courses, so that any change in mortar hardness across the wall shows up as a difference you can correct rather than as scattered depth variation. On repointing work, the depth you cut sets how much new mortar can be packed back in, so agree the depth before starting and set the pin once.

Heritage Restoration and Repointing

For heritage brickwork, matching the original joint profile and depth is the whole point of the exercise, and a fixed pin setting reproduces that depth consistently across a patch repair so the new work does not read as a different joint.

Lime mortar, common in heritage work, is softer than Portland cement mortar, so the timing and pin setting differ; always test a small, inconspicuous area first and re-check the pin setting on the actual mortar rather than assuming settings carry over from cement work. Note that on heritage exterior work the specification, not this tool, decides the final profile: if the original was a struck or weathered joint, this tool is used to cut the old mortar out and a jointer forms the finish.

Landscape Brickwork: Patios, Retaining Walls, Boundary Walls

Landscape brickwork is fully exposed, which makes the profile decision above more important, not less: raking a boundary wall in a wet climate builds in a water-collecting ledge on every bed joint. Where a raked look is nevertheless specified, the wheels let the same depth be run along a low retaining wall quickly, and the rolling action works on both vertical faces and the horizontal joints of paved work.

Concrete Block (CMU) Joints

CMU walls with mortar joints can be raked with this tool: the block face is flat enough for the wheels to track on, and the pin cuts block-bed mortar the same way it cuts brick-bed mortar.

The caution is geometry rather than material: block joints are often wider and more deeply recessed than brick joints, and the wheel diameter may not clear a deeply recessed joint. Confirm the pin reaches the required depth with the wheels still bearing on the block face, and trial one panel before committing to a wall.

FAQ

Q: Is "7"" the blade width?
A: No. 301110 has no blade: the cutting part is a single adjustable pin between two wheels. The 7" is the tool's nominal size, not a blade width.

Q: Are raked joints good for weatherproofing in rainy climates?
A: No. Raked joints are not recommended on exterior walls, because the profile leaves the mortar face uncompacted and forms a horizontal ledge that collects water and can saturate the brickwork. Where resisting rain matters, use concave, V or grapevine profiles, tooled with a jointer.

Q: What is the difference between this and a jointer?
A: They do opposite jobs. This tool removes mortar and leaves a recessed, uncompacted joint face, while a jointer presses mortar into the joint and produces the compacted profiles. Most repointing jobs need both tools.

Q: When is new mortar ready to rake?
A: On new work, use the thumb test. A clear thumb impression with no mortar sticking to the thumb means it is ready; mortar sticking means it is still too soft.

If new mortar crumbles or takes no impression at all it has gone too hard, so do not force this tool and switch to a hand tool or a powered mortar saw for that section. Old mortar being cut out before repointing is already hard: try a short section first, and use a hand tool or a powered mortar saw if the pin will not cut it.

Q: The groove depth is uneven, or the tool keeps drifting off the joint. What is wrong?
A: Both wheels must ride on the brick faces either side of the joint with the pin centered in the mortar; a wheel running in the joint loses the depth reference.

Also check that the pin has not slipped in its clamp (re-check the adjusting screw), and clean mortar debris from around the wheel axles, with a drop of light machine oil if a wheel binds. Where the brick face is too irregular for the wheels to track, use a hand tool instead.

Specifications Overview

Product Range

Model Size Size in mm
301110 7" ≈178 mm

The 7" is the tool's nominal size. It is not a blade width; the tool has no blade. See Full Size Reference below.

Key Design Features

Wheeled base. Two wheels mounted at the base of the tool roll along the brick face and give the tool its tracking. Two wheels are mounted side by side on the body, one on each side of the joint, with the cutting pin between them.

Cutting pin (not a blade). The cutting element is an adjustable pin held between the wheels, projecting down into the mortar joint. It wears with use; contact sales for replacement pins. The working end is the head end of the pin, not the point.

Depth adjustment. The pin projection below the wheel line is set by a screw in the body, so the rake depth is a setting rather than a fixed tool dimension.

Wheel guidance. The wheels ride on the brick surface flanking the joint and never in the joint, which is what keeps the pin at a constant depth.

Handle. The handle is a one-piece curved metal handle extending from the wheel body. The curve lifts the operator's hand clear of the wall face while the wheels are on the brick.

Joint profile produced. The tool cuts a raked (recessed) joint, one of the recognized mortar joint finishes, used for its shadow line on exposed brickwork. It is an appearance profile, not a weathering profile: see "The Limits of a Raked Joint" under How to Use below before specifying it on an exterior wall.

Body material. Metal body and metal wheels (contact sales to confirm material).

Skate Wheel Mortar Raker vs. Hand Tools

These are not alternatives for the same job; they are the two halves of a repointing job. The comparison below is about raking work specifically: cutting mortar out of a joint to a set depth.

Criterion Skate Wheel Mortar Raker (301110) Traditional hand tools (hand raker / jointer)
Depth reference The brick face, via the wheels, mechanical The operator's hand, variable
Depth along a long course Constant once the pin is set Depends on sustained operator control
Operator effort on long runs Rolling push force Sustained downward pressure
Tight corners, returns, short courses Limited, the wheelbase needs brick face either side of the joint Good, works anywhere a hand fits
Irregular or protruding brickwork Poor, the wheels need a reasonably flat face to track on Good
Compacting new mortar Not its function, a raker removes mortar A convex or V jointer compacts mortar; the compacted profiles are the ones that best resist water penetration
Adjustable depth Yes, by screw Fixed by tool geometry

When to Use the Skate Wheel Mortar Raker

  • Repointing preparation on any wall. Clearing loose or deteriorated mortar, paint and residue out of existing joints so fresh mortar can be packed into a clean pocket. This is the application that holds on every wall, exposed or sheltered.
  • Long horizontal runs where depth consistency is visible. Large facades, long retaining walls, boundary walls: anywhere an uneven joint line would read as a defect.
  • When a specified rake depth has to be reproduced. Set the pin once and the same depth is cut on every course.
  • Multi-story or extended work where operator fatigue is a factor.

When a Hand Tool or Another Tool May Be Preferable

  • Small, tight or intricately shaped areas, and joints close to a return where the wheelbase has nowhere to sit.
  • Around protrusions or on markedly irregular brickwork, where the wheels cannot track cleanly on the brick face.
  • New mortar that has gone past the tooling window. If a thumb leaves no impression on newly laid mortar, it is too hard to rake cleanly. Old mortar being cut out before repointing is hard by nature and is not judged by this test; try a short section first, and if the pin will not cut it, use a hand tool or a powered mortar saw instead of forcing this tool.
  • When the joint needs to be compacted rather than opened. Specify a convex or V jointer.
  • Budget-limited projects with a small scope, where the payback on tracking consistency does not arise.

Art. Nr Size Size in mm Material Handle
301110 7" ≈178 mm Metal body and wheels (contact sales to confirm material) One-piece curved metal handle

What "7"" refers to. The 7" is the tool's nominal size. The tool has two wheels, one adjustable pin between them with an adjusting screw, and a curved handle; there is no 7" wide blade on it, so "7"" is not a blade width.

Care & Maintenance

Work inside the tooling window on new work. New mortar that has gone past thumbprint-hard is too hard to rake cleanly, and forcing the tool is the point at which cutting stops and damage starts. Re-run the thumb test at each wall rather than assuming yesterday's timing. On old mortar, trial a short section first.

Bear on the head of the pin, not the point. This is a tool-life item as much as a technique item: the head end is the working end.

Take material off in stages. Working from a shallow setting toward the final depth, rather than one deep pass, is the correct method for this pattern and is what keeps the pin from snatching on aggregate.

Check the pin and its clamping before each use. The pin wears with use; check it is straight, not mushroomed, and locked at the projection you set. When it will no longer hold a clean cut, contact sales about a replacement pin rather than compensating with pressure.

Check the wheels before each use. Both wheels should rotate freely and run true without wobble; a wheel that binds turns the tool from a rolling reference into a dragging one.

Clean after each use. Remove mortar dust and debris from the wheels, the wheel axles and the pin housing before the residue sets. Set mortar packed around an axle is the usual cause of a wheel that will no longer turn.

Lubrication. If a wheel binds after cleaning, a drop of light machine oil on the axle restores free rotation. Wipe off the excess; oil left on the tool collects mortar dust.

Storage. Store dry, with the pin retracted or protected so it is not bent by other tools in the same box. Dry the tool before storage rather than leaving it wet from washing down.

Work inside the tooling window on new work. New mortar that has gone past thumbprint-hard is too hard to rake cleanly, and forcing the tool is the point at which cutting stops and damage starts. Re-run the thumb test at each wall rather than assuming yesterday's timing. On old mortar, trial a short section first.

Bear on the head of the pin, not the point. This is a tool-life item as much as a technique item: the head end is the working end.

Take material off in stages. Working from a shallow setting toward the final depth, rather than one deep pass, is the correct method for this pattern and is what keeps the pin from snatching on aggregate.

Check the pin and its clamping before each use. The pin wears with use; check it is straight, not mushroomed, and locked at the projection you set. When it will no longer hold a clean cut, contact sales about a replacement pin rather than compensating with pressure.

Check the wheels before each use. Both wheels should rotate freely and run true without wobble; a wheel that binds turns the tool from a rolling reference into a dragging one.

Clean after each use. Remove mortar dust and debris from the wheels, the wheel axles and the pin housing before the residue sets. Set mortar packed around an axle is the usual cause of a wheel that will no longer turn.

Lubrication. If a wheel binds after cleaning, a drop of light machine oil on the axle restores free rotation. Wipe off the excess; oil left on the tool collects mortar dust.

Storage. Store dry, with the pin retracted or protected so it is not bent by other tools in the same box. Dry the tool before storage rather than leaving it wet from washing down.
