Mortar Raking

About Mortar Raking

Mortar raking is an essential process for removing deteriorated or damaged mortar from between bricks and masonry blocks, typically in preparation for repointing work. MyToolShed.co.uk stocks a comprehensive range of professional mortar raking tools including power tool attachments, diamond cutting discs, TCT (tungsten carbide tipped) rake bits, manual rakers, and complete starter kits from trusted brands like Irwin, Bosch Professional, Faithfull, and Draper.

Whether you're working on heritage restoration projects, general building maintenance, or extensive repointing jobs, the right mortar raking equipment significantly improves efficiency and accuracy. Our selection includes both 240v power tool accessories for larger projects and hand-operated tools for precision work on delicate or small-scale applications.

Applications

Mortar raking tools are essential for:

• Bricklayers and stonemasons preparing walls for repointing and restoration work
• Builders and general contractors carrying out property maintenance and renovation projects
• Heritage restoration specialists working on listed buildings and conservation areas
• Property maintenance professionals addressing weathered or damaged mortar joints
• DIY enthusiasts tackling home improvement and garden wall repairs
• Plasterers and rendering specialists removing old mortar before applying new finishes

Choosing The Right Mortar Raking

Selecting appropriate mortar raking equipment depends on several factors:

Joint width: Match your tool to the mortar joint size – common options include 8mm and 10mm rake bits. Measure existing joints before purchasing to ensure compatibility.

Tool type: SDS Plus mortar raking chisels suit heavy-duty 240v rotary hammers for large projects, while TCT rake bits work with standard power drills for medium applications. Hand-operated rakers provide maximum control for delicate work or small repairs.

Project scale: Starter kits from brands like Irwin offer excellent value for extensive repointing jobs, including multiple cutters and adaptors. For occasional use, individual raking tools or diamond cutting discs may be more economical.

Material hardness: Diamond mortar raking blades excel at cutting through particularly hard or cement-rich mortar, whilst carbide-tipped flute cutters handle standard lime mortar effectively.

MyToolShed.co.uk stocks compatible accessories including sole plates for improved stability and adaptors for different power tool connections.

Safety Information

Mortar raking generates significant dust containing silica and other harmful particles. Always wear appropriate respiratory protection (minimum FFP3 rated dust masks), safety goggles, and protective gloves. Use dust extraction equipment where possible, particularly when working indoors. Ensure 240v power tools are PAT tested and used with RCD protection. Check walls for hidden cables and pipes before commencing work.

Frequently Asked Questions

What's the difference between a mortar rake bit and a diamond cutting disc?

TCT mortar rake bits use rotating carbide-tipped cutters to mechanically remove mortar and work well for softer lime-based mortars. Diamond cutting discs grind through harder cement mortars more effectively but generate more dust. Your choice depends on the mortar type and hardness you're removing.

Can I use mortar raking tools with a standard drill?

Yes, many mortar rake bits work with standard 240v rotary drills using appropriate adaptors. However, SDS Plus chisels specifically require SDS-compatible rotary hammers. Check product compatibility before purchasing from MyToolShed.co.uk.

How deep should I rake out mortar joints?

Generally, rake mortar to a depth of 15-25mm (approximately twice the joint width) to ensure adequate bonding for new mortar whilst avoiding structural compromise. Adjust depth based on the wall's condition and the remaining sound mortar.
