Did you use a rotary on this floor & which pad or brush did you use with The sts ?Great job , never used grout blaster I use STS from w.o.c bloody brilliant stuff as soon as you spray it on you can see the dirt and grease coming out of the lines the customer thought it was design strips at first but when she started to clean it she realised it was dirt so she contacted me to remove it all as it took her 2 hours to do a small area I did her kitchen , utility small hallway and toilet in the same amount of time
I couldn't use a rotary on this floor as it would
It was a sealed commercial grade floor you can call it karndean/amtico or call it what you like , I was very aware and very careful not to over wet the floor so it was literally the same amount of water that would be put on it as if the customer was going to mop it , never ever use hot water or steam on these types of floors as they are glue backed and can detach themselves from the substrate giving you a wavy effect and a potential insurance claim against you better to be safe than sorryNice one Vinny, great job.
The grout brush it a great time saver, gets right into the valley without contact with the rest of floor.
Do you know what sort of floor that was (laminate, engineered etc) I'd be worrying myself about water getting under it (probably a lack of knowledge that causes my worry!)
