Hey all,i decided to pick up the Bosch GSL2 laser i had asked about in another thread and so now im thinking i may end up doing more floor prep as one member mentioned.Ive scoured the net for reviews and setups and now im asking you guys,whats your dustless concrete grinding setup for residential flooring.Thanks

Aaaahh, my comfort zone. Here's my take, you can't tell the floor what prep your going to do , the floor tells you what has to be done. We've made good money on floor prep, focusing on it instead of " pushing it under the rug" hardwood, vinyl , ceramic. It's really a budget issue and what your needs are .

Mike i shoulda been more specific on budget,ive got a shop vac already so im looking at the actual grinder now.Not beyond a few hundred id say.Im looking at the alpha eco grinder or maybe the makita or bosch.If i start doing tons of prep ill upgrade to a higher end setup.

One leaps to the other, I had shop vacs, the large rigid ones, and I used the fine filtration bags, so I filled those, threw em away , start again. Keeps filters from clogging up.
I would say the dustgrabber 7" shroud attached to a dewalt, or actually they're (CDC Larue) using Makita grinders.
Eventually I got tired of buying the bags after 3 years or so, Jack King talked me into buying the pb-1250 and from there the door opens to excellent floor prep, so now I'm removing ceramic tile and thinset dust free, we've done all sorts of prep since then. Funny thing is I still buy(used ) equipment to see how it performs, I don't like skipping by leaps the quality and performance that I have. The little 4" CDC grinder does not perform well.

Ye the dust grabber looks like a solid product,is the actual material that meets the floor hard or will i be able to press down on the grinder should i need to.The ecogrinder has springs that let the shroud move up and down allowing you to put more pressure on the grinder and tjhats seems like a key feature.

The grinding blade rests on floor , the metal housing is suspended maybe 3/4" off the floor, the rubber skirt then is adjusted to set flat on floor blocking dust from flying outward . The suction comes down from around skirt and evacuates into vacuum line . So you can press down as hard as you want, it's all blade.

That grinder gets close , then for flush I have a pearl abrasive shroud on a 4 " grinder that gets right up to edge, attached to a bosch. 3931 vacuum with wet/ dry vac 022 bags.
I just recently bought Jack Kings Dustram shrouds , they're around 1000$ each, I have 2 edgers 1-4", and 1-7" grinder. I do dust free tile removal and concrete grinding , so it's building up equipment getting faster and cleaner. I have a long way to go still , just continuously improving using money made to reinvest getting more equipment.

I know very little about the Larue grinders, having no direct experience with them. Im actually a distributor for the vacs, attempting to bring them to the hardwood floor sanding world. I have owned and used Clarke Cav 12's, ceno cyclone vacs, clarke Cav 26, basic dust dragon, assorted other vacs.. None come close to the 1250 on pure, all day performance.

Will the urethane removal of the finishes stick/wedge to the filters on the cdc vacs? For general cleanup they work awesome. I've had vacs that wouldn't pick up tackstrip nails, so I had to pick up by hand. The vacs are the heart of floor prep.

Yeah I want two more myself, to start with. I don't have that laser though, just my straightedges, other lasers. The CFM of the 1250 is phenomenal.

Mike try it with a 5" wheel for thinset removal I find it seems to work better with the smaller wheel.... I got mine used with the polisher included.
