I bought a Termite mortar raking starter kit as I needed to remove mortar to fit lead flashing to a roof I'd built at home. The order was received quickly. It's very easy to set-up. Fitted to my 4.5" grinder without any issues. The unit is extremely easy to use and gave me (a DIY'er) a professional finish to the job. I used it for 7 meters of mortar and it took me roughly and hour and a half start to finish and that includes me getting set-up and lugging the Henry hoover up onto the roof for dust extraction (which worked perfectly). Very handy tool to have in my garage.
