concrete grinding

We finally got the quote to get our concrete floor ground to level, $800 to $1300 plus GST. Today we went to check the hire places with the view to do it yourself. Two different machines and two different prices. We returned home then Dad decided to get the closer and cheaper option and make a start.
Five hours of grinding later, he has almost levelled the two slabs. Still to surface grind the rest of the floor. With an approaching blister for him and one in place for me, we adjourned at 5.30pm. Hopefully a good night's sleep and we'll be fresh to continue. I got my blister sweeping the concrete dust away. We filled two buckets as well as the vacuum cleaner. I used the air con to blow air into the room so the open windows carried away the rest. Dad used his compressor to blow the dust that settled on the outdoor furniture. More again tomorrow.
