Polyaspertic-Install problem...

[goddi1]

Greetings,
This is my first post so I hope it is in the right section.

A company recently started the project to seal my garage floor with polyaspertic. I am not having the vinyl chips added. The concrete floor was grinded (ground?). The first coat was a color coat. When it was dry, I noticed debris throughout the 2-car garage floor. It looks like bits of dirt or sand just under the surface, everywhere. Some are larger bits of something. I complained. They sanded (buffed?) it and put another color coat. Same thing, maybe worse. I complained. I think they think I am over-complaining. I suggested that even though I don't want the chips, maybe adding them could solve the problem. He said he won't do it because "you won't be satisfied". I think he is nuts.

Their solution is to sand it again and put on a tinted color final coat. I am at my wits end in trying to get them to see that this debris is unacceptable. In a couple days, they are scheduled to do the final tinted color coat. The debris in the finish is spread evenly throughout the garage floor. At first I though they were just bubbles, but it seems to be solid stuff. Some small, some larger. Can anyone guess what it could be? I am worried since they can't figure out (or they won't admit or tell me) what the problem is, they will just be repeating the problem in the final coat. Any ideas?

Bad batch of coating, cheap rollers, dirt, debris, etc.......

i bet they used cheap roller covers and its delaminating on them....happened to me when I first got in the biz over 10 years ago.

======================
They put down the 3rd color coat (final) and it also is full of the roller lint.

So now I am thinking of having someone else put down another coat with chips. I'd use a single color of the chips. My question is can I wait to have this done, or should it be done within a particular span of time from when the last coat was applied?

Does the shine have to be buffed off before the next coat?
Will it get too hard to buff the shine off if I wait weeks or months?
What should the process be? Buff-clear coat-add chips-clear coat?
Thanks... Gary

Have you checked with Gene or Scotty to see if they have a reputable contractor in your area that might be able to come in and fix this for you? Have you paid these folks?

We need pics here...

But it sounds like cheap rollers. I too hope that you didnt pay them yet....

For the rest of , will you pros please specify what brand and size, shape, diameter , width of rollers covers you reccommend.

 

[LegacyIndustrial]

What is your product, size of room, smooth newer concrete?

Another possibility is that these guys are top of the line hacks that never considered alcohol or solvent wiping the surface after sanding and before applying the coating.

The exact same thing just happened to me and the company is offering to to sand and re-coat. My questions are,

1) what would happen it I just left it and used the floor (I have a lot of pressure to move into this shop)

2) what rollers/roller covers should I insist he use so it doesn't happen again.

3) how long does the floor have to cure before sanding and recoating?

4) he used a pigmented urethane, could he coat it clear if the clear is easier to get faster?

Thanks in advance to all of you experts.

Non-shedding rollers. He should wrap any roller in duct tape and then remove it to remove an shed prior to using.

Read the tech-data for cure times. I would give it 24 hours to be safe.

Clearing a urethane with another urethane will require the same sand/solvent wipe process. I would stick with the same product.

Again, clear all this with the manufacturer. There are some urethanes (tennant) that cannot be double-coated. Only epoxy-primed and then coated again with urethane.

Mitch, debris in the coating is usually a result of not running a tight ship. Make sure he does a real good job cleaning the floor prior to coating.

Good luck and keep us posted.

Thanks for the quick answers. The floor is 4 days old and I was wondering if you had to wait a certain time after the inital cure before re coating. I paint cars on the side and that is ofter the case.

I am also wondering if the floor would be usable other than the cosmetic problems? Would the trash wear out and leave little "holes" for oil and gas to mess things up? A small part of me just wants to adjust the final price downward and be done with it, but I spent the money in the first place to have a tough long lasting floor.

Here are some pictures so that maybe others can find this thread useful.

That looks more like applicator induced than a vendor product problem. One thing to have these guys consider is the product they are using has a heavy solvent base. Some roller covers fall apart with certain solvents.

I'm seeing air induced bubbles, possibly due to mixing incorrectly, I'm seeing dust and larger particles. I am also seeing possibly resin that has dried or starting to dry caused by reusing a mixing bucket.

Fair enough but I would like to know who is doing it so they don't get the chance to do ity to me

Love to learn from others mistakes, its less painful

Agreed. Of course they may have all the bugs worked out by the time this crew reaches you.

You can cross all your t's and dot your i's and something can still bite you in the *** in this business. Working with an organic compound like concrete, using finicky chemicals, something unusual or unexpected is bound to happen.

Best bet is have this guy screen it and reapply with good rollers and add a non slip texture because it will be slick as hell.
