Epoxy Coat prep question's

[Robert 2006]

1) When you diamond grind the floor, you get about 90 percent of the floor ground. This is due to the floor not being flat and using a 4 dia grinder. Will the Epoxy Coat pre cleaner take care of the rest?
2) I was planning to install the floor this weekend, but rain is planned. Would it be better to hold off?
3) How long do you need to let the Epoxy Coat dry before laying down the clear coat without having to sand?

Thanks in advance
Robert

Hi Robert,
1. the prep/acid will take care of anything the diamond missed. Make sure you triple rinse the floor to remove all traces of acid.
2. It is better to hold off during the rain, it can change the look of the floor. If any rain gets on it while curing it can leave a mark or cloud it.
3. You will need to apply the clear coat about 18 hours after the base coat. If you wait more than 24 hours, then you will have to scuff the surface before applying the clear.
Let me know if you have any other questions.

If you can't shot blast , grind, diamond, stone sand whatever but acid is a no no I know I will catch hell for this on this site for this but there is a enormous amount of facts out there that indicate that acid should never, I mean NEVER be introduced in to the capaliaries of concrete..

I haven't seen any of the companies on here say NOT to acid etch!!!

If you are diamond grinding the floor, I dont think you need to acic etch. How old is the floor? Mine was fairly new when I put my epoxy down. All I did was diamond grind, rinse(let dry 24hrs) and roll it down. Its been a year and a half and its holding up real good.
Depending on your climate, I would wait till late spring before applying your floor. You only want to do this once.

After looking at the photos, I do not think it will be necessary to acid etch. I think your doing fine with the grinding. BTW, this has absolutely nothing to do with what scout57 said. We include acid in all our kits and it is a perfectly fine method of etching your concrete.

I am not going to start anything here but there an entire industry built around the business of preparing concrete for various topical applications of materials for various
reasons, coatings , toppings repairs etc etc, there is also a business of defending or prosecuting the party's in a legal dispute as result of not using available best practices.
if you care to gain the knowledge do some research on the INTERNET, start with the ACI American Concrete Institute , or ICRI The International Concrete Repair Institute, there is a lot of good people on this site , they have not been tested yet , as we grow in life and in business we learn , Me ,I learned the hard way , lets just say I would NEVER let anyone that works for me introduce ANY acid or other wise into concrete period!

Keep things in perspective. We're talking about home garages, not a mission critical application.

so lets let folks just live and learn on there own ..I wounder if anyone that see this site would like to share with us there experences after a floor fails and they need to go thru the process and expense of correcting the problem , it's just a garage floor? I bet the fella that droped 400k on his build would dissagree with you and I would ventura to say others might as well, however point taken I will keep my opnions and otherwise to myself..after all you are senior to I

Do we see many 400k home garages on here??

Everyone is entitled to their opinion. I for one plan on checking out these sites to check whether grinding may be an option versus the acid. I don't think we should be putting scout out unless someone is a true expert on the subject.

Just my 2 cents.

yes.
we see enough.

For what it's worth; acid etching has a tendency to soften the top layer of concrete. It needs to in order for coating applications to adhere to it. I know a number of people who did not rinse well after etching or put the product down to soon and about 6 months later is when the problems began to show up. Scoring with a diamond grinder is the best option in my opinion. Shot Blasting will leave visable score lines with thin film coatings and with some full chip applications in direct sunlight. Probably not a big deal, but quality applications are in the details.
