Finished quikrete epoxy tonight..Help!

[DatacomGuy]

Applied epoxy tonight.. about a few hours ago.

I have a few spots where it looks like the epoxy is thicker from the roller overlapping or stop points then in other spots. Kind of looks crappy in quite a few spots.

Is there a remedy to this? I have another kit that I can use to remedy, but I was afraid that if I rolled on a new coat over these issues, that it might be thicker then the rest of the floor, and noticeable..

Thoughts? Am I OK to just use the next kit to fix?

Help!

you need to backroll after spreading to even it out... also lift up the roller before it stops moving so you dont get the start stop marks.

Sometimes this stuff can be tricky

What kind of roller are you using length/nap? How far are you spreading a gallon? You might be going to thin and not getting good flow/ self leveling.

depending on how bad it is now and how thick the next coat is it may or may not hide the imperfections.

The only way to have an even floor using a ~50% solids waterbased product would be to start with an even floor. The problem is that even if you try to roll the next kit, you could end up applying it too thick in some spots again. Waterbased epoxyies are notorious for severe yellowing when water is trapped in them from applying them too thick. If the product you were using were a high solids I might suggest that you could just add some thicker... but... the best course if probably to sand the floor smoother and apply one good... even... coat over the entire floor.

It may not have been quikcretes water based epoxy he never specified... they have a few. Not all water based.

I even saw a 100 percent solids epoxy at lowes or home depot but i dont think it was quickcrete it was one of the "others".

Well, I definitely backrolled.. and I rolled in multiple directions to ensure proper coverage.. disappointed with how it looks right now, and wife is too. When wife isn't happy, ain't nobody happy!

Using a premium 1/2" nap, standard length. A full kit is lasting me about 280sqft. I'm afraid I might be too thin as well?

Suggestions on correction? I have about 50sqft left to paint (couldn't paint there last inght because it had been raining and it was moist)... and a new kit, so I'll have a TON of paint left. Tons of flakes left too. Should I roll a new thin layer? Will it make a difference? Spot paint?

Moist, what was moist?????

Moist, what was moist?????

The concrete, where I did not paint. Right along the edge of the garage door. I had the door cracked open by about 2 feet, and some rain got on the floor.

I stopped painting about 3 or 4 feet from the door.

 

[Mlynch]

thats tough... You can finish the last 3 or 4 feet but you might get a seem from where you stoped and started back again... you are supposed to always keep a wet edge with these unlike paints because they are thicker and you can see the seam or ridge. Maybe you will do fine.

I hate to say it but if you spot paint this same thing MAY happen.

Wolverine actually gave good advice you should probably sand out the areas with imperfections/ lightly sand the entire floor and do the entire floor over. To make this go a little faster use an 18 inch roller.

Maybe show us some pictures and which quikrete epoxy are you using?

Have same problem with overlap. Called company and they suggest recoat using 3/8 foam roller. Will be trying when rain stops. Let me know if your recoat worked.

 

[T-Ricky]

Please give me peace of mind. After talking to Quikrete (1-800-458-0047) the only suggestion was to recoat and use a 3/8 foam roller. They said a clear coat might help, but I am thinking it may enhance the problem more. I am going to try sanding with a coarse grit using a sanding pole. After cleaning dust I will try a early (5-6am) recoat in hope of maintaining a wet edge. Temps here are 80-90 degree and humid. First coat was done midday in hotter part of day thus giving a bad lap mark all over the floor. PLEASE RELAY ANY ADVICE YOU HAVE AS I WILL BE STARTING SOON. THANKS

 

[DatacomGuy]

Are you going to sand the whole floor? Or just the overlaps?

Wont' that give you more overlap?

 

[T-Ricky]

I am going to sand whole floor with more focus on the lap marks. See other threads.

 

[T-Ricky]

Just got off the phone with Quikrete. They say sanding will help with adhesion of second coat and there is no time frame for recoat or need for solvent wipe. Let me know what you think?

t-ricky datacom check this link for their instructions

Notice under the section with previously painted floor it said to use a chemical deglosser... that is solvent wiping. Their techsupport seems sketchy escpecially if they are telling you to skip steps and telling alpha that its okay to apply 12-20 mils.

As far as a recoat window that refers to the amount of time you have to recoat without sanding... it does have one.

When I had a few marks like you describe, they pretty much disappeared once I broadcast chips.

How did yours turn out?

 

[DatacomGuy]

I called, they said solvent wipe not needed as well.
