Diamond grinding wheels

[mml665]

I am in the process of converting a spare room in my basement into a hobby room for my children and I. I am considering an epoxy coated floor, I have done my garage floor which only required as the concrete was new and not walked or driven on for two months all we had to do was acid etch. The floor in the basement room is original to the house, I am not sure if it is sealed, however there are paint and other stains. I would like to know if anyone has used the Harbor Freight diamond grinding discs? Which tool or method creates the least amount of dust? The floor is 13x21

If its a 1 shot deal, I would bet their disks are good enough. I would spend a little more and get one not made in China, the diamonds will be better, and last longer, and the bond more consistent. Try "World Diamond Source" if you want a quality one. I think the one I bought recently was $65. Makita also makes super cheap generic dust shrouds. $50 for a 5", and $90 for a 7". I saw them at the world of concrete show last week, and was impressed, they have little brushes instead of a rubber/pleather skirt.

If you dont use a shroud you're in for hell of a dust cloud.... Think Cheech and Chong.

Even with the shroud, your vac will clog. Keep a spare filter handy for a quick change.
You can get grinder shrouds for less than mentioned previously, good enough for a 1x job.

Oh boy guys my wife is the definition of OCD when it comes to the house being clean. Do the bigger units like the rental surfacers or grinders kick up less dust? The floor will only see foot traffic, but I would like the opportunity to get some grinding practice

The bigger surface grinders like the dual head units don't create nearly as much dust when using a vacuum because they turn at a much slower RPM. That said, you still will need a small grinder to get the edges and corners of the floor.

No matter how you look at it you are going to create some dust in your basement. Just break it to the wife gently.... Since your floor is under 300 sf, you just might want to purchase a cheap 7" grinder and shroud to tackle your floor with frequent stops to clean and possibly replace some filters along the way. Like Scotty said, a regular shop vac is going to clog fairly quickly. Being in a closed room I would suggest some earplugs and a respirator as well.

Unless you have a walk out basement some of the larger rental machines will be difficult to get in and out of the basement. If you get suckered into renting a edco machine, rent their 10" single head machine with a diamond segment blade. The dual heads are ****.

You have 2 choices on dust control. Get the shroud and vac or go with a wet grind. A wet grind produces a slurry you have to dispose of.

Here's a cheap start up kit I sell to my trainies:
Dustless dustie 7"- (you can get these at www.ohiopowertool.com) for $24.95
Dust Deputy by www.oneida-air.com (use this with you regular vac and it will save the filter) Less than $100.00

I'm getting a large order in for 7" 12 segment cup grinders that will sell for $30-$35 a piece. You can find these all over the web for that price. Get 30-40 grit medium hard. That will cover the different concrete pretty much across the country.

You should be able to set yourself up with a grinding system for under $175.00. (You would have to have a 7" grinder and shop vac.)
The vac pre-seperator is a good thing to have around for the shop so that would be something I would hang onto.

DCS I actually have two grinders that are handheld but the dust separator sounds interesting do you have more details

Alot of the Home Depot rental stores have the new Diamabrush grinders and attachments. Never used one, but supposed to work great. And can be done wet or dry.

 

[mml665]

Jamie interesting suggestion! I a. Wondering since it will only be foot traffic do I have to grind the floor

I sell them to a lot of newbies to get started that don't have a lot of start up cash. Most everybody has a vac system and this prolongs the filter clogging. A lot of guys attach it to their present vac so it all rolls together. (comes with that hardware also) It produces a cyclone that forces the dust down into a 5 gallon pail and not directly to your vacuum. Works pretty good. Go to their site and check out the dust deputy deluxe.

I will for sure! I appreciate the info. Being self employed I don't mind investing in tools and materials since I am the labor lol. When I remodeled my home all the money I saved on labor and skilled labor afforded me the ability to upgrade the materials used. Lol
