Product Information

However, care should be taken as there are multiple subtypes of woodworking chisel available and it is important to select the right type for your requirements. If you remove mortar to any more than 20mm deep, you can risk weakening the bond between the bricks. Masonry chisels are often attached to hammer drills or jackhammers and used in the process of demolition.

If you remove less than 15mm of old mortar, any new mortar will not have enough surface to bond fully and will fall out in a matter of months and you will need to redo the job again. To prepare the area for repointing I first needed to rake out the old mortar, to give me a good base to work from, and doing this the right way will save you money and time and make your brickwork strong and last for many years. Care should be taken to strike away from the body and only extract a small amount of wood with each strike. Before beginning work, it is recommended to mark the material to be chiselled with pencil or paver’s chalk. Remember to always follow the manufacturer’s instructions and wear the appropriate protective clothing.The Hammer and chisel is the most accurate method to cut out the old mortar and can be used in space that an angle grinder will not fit like internal corners or tight gaps. Once the old mortar is raked out, the brick can be broken out using a cold chisel or plugging chisel and a lump hammer; carefully cut the brick out by breaking it up in place and removing the bits as you go. Using the right tools and preparing your brickwork properly by raking the old mortar out the right way will make repointing with new mortar much easier, and give you a professional finish, read my detailed guide below and video at the end of the post to find out more tips.

I set the drilling depth by checking a brick at a nearby corner or the end of the wall, just make sure the same bricks have been used as the one you are going to remove. When raking and cutting out mortar in preparation for re-pointing the brickwork the depth of the cut should be enough to clear the old weathered mortar but not too much to weaken the bond between bricks. After all the old mortar has been raked out, the bricks need to be cleaned down to remove all the loose material and brick dust. Before you start cutting away, have a good look at the area of brickwork that needs to have the mortar raked ready for repointing, if it is a large surface consider breaking it down into smaller sections, to repoint a 1m square area will take an average skilled person about 2 hours.When you have no other choice but to use the angle grinder without extraction, try spraying the mortar and brickwork with water before cutting to help reduce the dust. You will need to plunge the cutting disc in the center of the perp and be careful not to touch the course of bricks above or below otherwise the disc will cut into the brick as well and start to make things look messy. Whether it’s a general purpose chisel or an application specific tool required, our diverse range has chiselling with an SDS Plus machine covered.

Place the broken bits into a bucket so they can be thrown away or reused as hardcore on future projects. It is common for tools of varying sizes to be used on a single project as large chisels can be used initially before smaller tools are used as the project progresses.You can even use an old flat-bladed screwdriver to rake out old mortar but these are not as good or as fast as using a hardened chisel which is made for the job.
