I don’t know for sure Chris, but the mixing may have had something to do with your problems. A couple of possibilities are:

1. The hardener percentages weren’t the same for both batches.
2. When the two batches were mixed together there was some of the epoxy in one container that was not mixed as well as the other. This often happens at the bottom or the sides of the mixing vessel. Be sure to scrape the sides and bottom of the container as you are mixing so you don’t get resin with no hardener. If this gets poured out then it will not cure properly.

As far as a fix goes, your best bet is going to be to scrape up all the mixture that did not cure, re-prepare the surface and then coat again. This will probably not match perfectly but if you feather the edges into the cured parts of the floor it may not be noticeable. If you don’t like the results, you can apply an epoxy coat over the entire floor again with a thin layer. This should make it more uniform. Be sure to “rough” up the surface of the cured epoxy so the top coat will adhere to your original.

I hope this helps, and thanks for stopping by my blog.

Andy, you know my brother in law and I did this. He has done 2 others prior to this. We thought that since there were two of us and we were working out of a 5 gallon bucket, that we could mix 2 gallons separately and then pour them together in the larger bucket. We were sure to go pretty quick. Anyway, it’s the very first area we painted that hasn’t set up yet. There are some areas within the area that are not tacky, yet the tacky areas will catch a leaf.

Hi Chris,
I sounds to me like you had a problem with the mixture. The fact that the color is different and it didn’t set up properly would indicate that either there was not enough hardener or it was not mixed up enough. I would let is set for a week and see if it cures. I am not sure it will. As far as your foot print goes, if it is into the coating then you will have to grind it out and reapply.

Completed this job yesterday. Its about a 4 car garage. Noticed a swath across the floor where the color looks different. Size of the area is about 10′x24′. Its been about 27 hours since the job was completed, I thought I would walk over to the area to check it out. I was clear until I stepped on the first area we placed and there is where my foot stuck to the floor? How is it that the oldest area was still sticky? Do you think the colors will ever blend and do you think I can get the “dirty footprint” from the floor where my foot got stuck?

Hi Zak,
With a temperature of 80 deg, I would give it a week before driving on it. Also, make sure the garage door installer protects the floor when using a ladder. After it is completely cured it is very tough but he could scratch it before it is completely cured. I would recommend placing his ladder on a sheet of plywood.

Its August but we have a break in the temperature about 76-80 degrees and its inside a new garage so nothing has been driven on it or anything. I will give it about 2 days before i have a guy coming to install a garage door opener and at least 3 days before I drive on it. Do you think that will be OK?

Hi Steve,
The two main considerations are to get the salt washed off the floor real well and then creating a plan for applying the coating. A 4 car has a lot of area and you definitely don’t want to mix up enough product to do this area all at once. If you did you would end up with the epoxy starting to cure in the bucket and this is a big mess. Only mix enough product to do thirty or forty square feet at a time. This would be a big project in one day so you may want to get some help or apply the product over two days. It can work well having one person rolling and one mixing for the next section. Don’t forget to spread the anti slip medium as you roll the epoxy mixture out and before it skins over. If you are going to spread it out then put your seem between the stalls at it will be less noticeable if at all.

Hi Rich,
As long as you apply the epoxy inside you don’t need to apply a sealer. If you bought a kit then everything will usually come in the box. If you applied the epoxy outside then you need to worry about clouding from the Sun’s UV rays and a coating can help with this.
