Is this enough diamond grinding?

[TOYSTRY]

Have a contractor at my house, so far, this is the progress. What I'm wondering is how much of the concrete needs to be roughed up and if they are doing it right so far?

I want to be able to intervene before they start laying down product if it's not rough enough or not done properly.

Appreciate the assist.

i think you either trust the contractor or not, to be honest. are you really going to tell him to stop working because someone on the internet didn't agree with his work?

First 3 replies and not one of you answered the question . I'm not familiar with this process, so I am seeking advice from those who have done it before that can provide some insight. It's not a matter of trusting the contractor, it's a matter of being knowledgeable on what I should be getting for the cost associated.

Here in San Diego the prices are dramatically different than what most people say it should cost (it's much cheaper) and after talking to a half dozen contractor, who's prices fluctuated as much as $1000, I'm trying to make sure I have as much information as I can to be knowledgable on what's considered "good practices" to ensure I'm getting what I paid for. I've had people tell me they acid wash, diamond, bead shot/blast, etc etc.

If I were doing the floor, my thought is that there should be "no shiny surface" left after diamond grinding, but that's because in my mind, that seems right. But there are a TON of companies that provide good info and feedback and I do value their opinion/suggestions, as well as all users who can shed some insight on the process. I mean after all, isn't that the point of this forum......to come, ask questions, offer assistance?

So.........with that, does the floor look like it's being diamond ground enough.

The folks here are being rather hard on you but they have a point. I'd talk to the guy doing this and let him tell you. You know ******** when you hear it, right?

I'm not that experienced with floor coatings, but I am with coatings in general. I look for:
Cleanliness (no dust)
NO residual moisture
Proper pH (within a reasonable range)

With that, I don't place a huge emphasis on the grinding.

Thanks for the info. I read a lot of articles on the difference methods and want to ensure it's getting done right and I'm getting what I paid for. It's not like pairing a house where you slap two coats of paint on it and call it a day. The prep is the most important part and I want to ensure two years from now it's not peeling up from improper prep.

Coming from a service industry salesman, you have every right to question his work and assuming you didn't make the mistake of paying before work was done, let him walk on ya and let him pay court and lawyer fees to try and get money from You.

If he did walk offer to settle by paying him a % of the work but do so via email or text so you have a paper trail and if he ain't happy let him take you to court, probably coat him more than he'll get.

Mist the shiny places of concern with water and see if it wicks in immediately. If not, grind a little more.

You have the right equipment there. However, besides having to turn my laptop upside down to view them, you are not close enough to the surface for me.

Talk to the contractor and perform your own water bead test. Water beading and not soaking in, NO GOOD.

 

[Toomanytools?]

Ditto on the upside photos, To answer the question it's very hard to see if the surface is in need of more grinding.
Like it was mentioned above do some water tests see what's happening. Don't get all "Jack Straw" on the guy and lawyer up. Most service contractors want some % down to get started.
Just ask they guy be up front tell him your concerns if it's ground enough and how does "he" test to see if it is. No product is down yet, let him do his job.
Hope it all works out, keep us posted.

Ya, despite my best efforts (the photos were imported properly) this forum flips them and I couldn't get photo bucket to host them without some 3rd party fee (I guess you have to pay to host pics now).

I never put down a deposit, but the job is done and he's been paid. He diamond grinded the floor pretty good, but I would have done have left "no" shiny spots.

Wish I knew this yesterday, too late now. Product has been applied, job is done and now it's drying. Appreciate the feedback regardless.

See above, but thanks for the gouge.

Concur, I do have a right to question stuff that "I'm" paying for. The job is done however, so time will tell if the job will hold up now.

To be fair I was not suggesting getting a lawyer involved, on the contrary

Having to post one pic at a time to get them to post upright.

And another pic.

And another.......I had to flip the photos 360 degrees, save and then I was able to upload them right side up.

Today they came back, scraped, sanded and polyspartic'd. Will post up finished pictures tomorrow.

Howdy Toystory, looks like your crew did the real deal. I'm moving this weekend, and it took me a long while to find a contractor up in Ventura who would do it right; diamond grinding. I did my current garage with professional materials. I did a hydrochloric acid etch on a brand fresh surface. I've had no problems in the 10 years I've been working on the surface.

I'm having a professional company do my new one because A) I'm shy on time now-a-days, B) the foundation is 1.5 yrs. old, not fresh, and C) I want a more consistent look. I am, however, filling the control lines with a high-elastomeric epoxy filler before they begin. The diamond grinding is totally the way to go. Plus, your later pictures look like they did a pretty thorough job. Glad you did your research too, and that you got a good team in there. Cheers!

Now, MORE PICS OF THE FINISHED PRODUCT..., please!

Sorry Jack, no harm no foul. Some people go right to "I'm getting a Lawyer" verses letting a guy finish his job.

Hey Toystry, looks like it was prepped well, still hard to tell in pictures but didn't see any glaring bad spots. Guess time will tell, is there any warranty 1 year...? Looks good though and nice to have done I bet.

 

[JStar4]

Looks like they did a good job. Love the polyaspartic top coat!

Hey Toystry,

I'm just right up the road from you in Murrieta. It looks like we have the exact same garage. Just wondering if you would recommend this contractor and if you don't mind how much you paid? I'm thinking about doing it myself but trying to figure out the cost difference. Thanks for any info.

Time will tell how it holds up. I'm always skeptical with hiring people as I don't trust many folks to put in a hard days work these days but they did a good job, were efficient and courteous.

Here is the link to the Yelp where I found them. I haven't left a review yet, but I will give them 4 or 5 stars (for now).
