After hours of grinding the mortar out of the walls, practically every car and garden in my street was covered in cement dust. It was obvious to me that I had to find a better way of doing this job, or at least cleaner! I needed to find a way of removing the mortar without throwing the dust great distances. Grinding discs spin at several thousand rev's per minute creating a mini whirlwind effect w
hich launches dust far and wide. This is because mortar is brittle in nature and turns back into dust with impact or grinding. Cutting the mortar using a saw blade takes advantage of mortars brittle nature and removes the whirlwind effect produced by the grinding wheel. There is still dust but the majority, about 75% just falls to the ground by your feet very little is airborne. The benefits of this are as follows:
• Reduced personal risk due to inhalation of dust.
• Reduced risk to the environment.
• Reduced risk of physical injury (Hand held Grinders are notorious for kickback/cutting injuries).
• Less time spent on clean up at the end of the job.
• Can be used indoors with no need to mask the entire area.
