These pinholes are caused by air bubbles formed in the epoxy coating during the application process. (some people mistakenly assume that they appear later once the floor has cured. This is wrong)
Repairing bubbles once cured is very difficult (or nearly impossible without needing to re-coat). Therefore the entire strategy for avoiding bubbles will need to fall on prevention of air bubbles. Over the years I have come to identify the key factors that can lead to the formations of bubbles in epoxy floors. Some of these I learnt the hard way, meaning that I encountered a cured floor with bubbles and needed to explain to the customer. And therefore I now make sure that most possible causes of bubbles have been eliminated before applying the epoxy coating.

This video is a very useful guide .... Its contains almost every single point that needs your concentration during epoxy flooring.
thanks im glad you liked it!
Thank you,good job.
excellent video! im interested in starting a business at this and this is the first time ive heard all this, and probably saved my butt from a few disasters right out of the gate!
Very helpful explanation. Thank you!
G
Informative video! I am also taking the course and learning quite a bit. Thank You!
Thanks for your feedback. I am very happy that you are learning from the course!
Very interested. Thanks
thank you! nobody talks about this stuff, just how easy it is to lay a floor, but not what can go wrong or why. or how to avoid it.
Good movie ,thanks .
Very helpful. Thank you so much!
Glad it was helpful!
Awesome presentation!! Very helpful!!
Glad you liked it!
Thank you, very informative!!
Glad it was helpful!
Extremely helpful! ran into this problem in one section no I can save the rest
Glad it helped!
Good knowledge for beginners
thanks
Useful information
thanks.
What's the proper formulation used in a good Epoxy resin?
Could you put a good dpm over the concrete to help
Thanks
do you have bubbles and such problems with Polyaspartic? or just epoxy? or polyurethane?
Hi, if you have a bad case of bubbles in your newly laid epoxy floor - what's the best way to repair it? Remove all and start again? Or just keep patching up and recoating? Also, should the surface be sanded before re-coating ? (eg. to remove the bumps from bubbles which haven't broken through the surface).
No need to remove it, that will be a massive hassle and would take days. Just patch and recoat over. Good luck
What happens if I mix the epoxy at a slower rpm for e.g 200 rpm?
What are your thoughts on the Sherman William products for Epoxy?
Sorry but I have never worked with these products. I am based in Europe
Good explanation. Thank you. Sir I have few questions:
1. Can I apply self levelling epoxy to an outdoor area?
2. Can I apply self levelling epoxy to bathrooms where floors are usually unlevel because of drainage?
3. Is self levelling epoxy more durable than tiles?
4. Is self levelling epoxy more costly than tiles?
Thank you. More power to you sir.
Hi 1) I do not recommend epoxy for outdoors, watch this video for more info ua-cam.com/video/-I62QkqIP8w/v-deo.html 2) I do not recommend this, the epoxy will run into the drainage, you may be better of with roller applied epoxy 3) It is very durable, the only tiles that have equal durabilty are the industrial tiles 4) Depends on the quality of the tiles and the existing setup and substrate, and the labour that needs to go in for each case
do you have an affordable yet effective primer you recommend?
Always go for epoxy primers when applying epoxies. Even if they are more expensive. The risk of damage is too big if you choose a different primer
Hi, I installed an epoxy floor with a final polyurethane layer. The day after floor was covered with plastic in order to be able to paint some walls. Two weeks later several bubbles apeared, all of thw bubbles have water underneath. Could the plastic provoke the bubbles?
It is very unlikely that the plastic provoked the bubbles. If there is water underneath it means that there was trapped moisture or rising dampness in the substrate. Epoxy and PU (I am assuming these are solvent based) are not breathable products
Hello. Are epoxy floors safe on humid and hot countries? I fear for the toxic fumes that may escape when epoxy become too hot. Please do clarify me. Thanks.
yes absolutely. Epoxy only gets dangerous at temperatures over 60 or 70 degrees celsius when it heats up and starts to disentigrate
Hi,
Kindly tell me how to prevent these bubbles after the application of top coat.
Suppose in a case it appears after final coat.
Thanks
Bubbles will only occur during the curing process. Once the floor is dry they cannot emerge. But sometimes pre-existing bubbles may collect dirt and will become visible. They were there from before
Good explanation. Thank you sir. I have 3 questions:
1. Can I apply self levelling epoxy to an open air or outdoor?
2. Can I apply self levelling epoxy to bathrooms where floors are usually not level for drainage?
Recently had a top coat done on an concrete overlay, by the end of the day I noticed sporatic dime sizes bubbles. What could have caused this?
I am assuming that the concrete overlay had not been primed or sealed? The concrete probably released air when the topcoat was being applied. Also in the summer we have an additional problem that as the temperature increases in the morning, the concrete expands. It is advisable to apply in the afternoon in these cases
I inspected it and noticed pin holes in the overlay it was top coated idk about primed but the holes seemed to have caused it. The solution the company is offering is to sand down the craters and I guess spot fill. They claim you will not be able to see a difference when done I'm hesitant to believe them.
You said no 5 reason give you a feel about the floor, so after you applied primmer you see where problems are, so if problems what would be the correction step plz advise
It depends on the problems that arise. If oil rises to the surface, it means the floor needs better cleaning. If new cracks become visible you need to patch up the cracks first. Depending on the problem, you will need to find a solution
My patio guy said they will cure over time. Spike holes caused by his shoes. Is this correct?
Holes caused by the spiked shoes happen during the application when he walks on the still wet coating. These holes should close within a few minutes. If they don't go away it usually means that the coating had already started curing and he left a permanent mark.
But this video looks more at bubbles and pinholes caused by degassing rather than spiked shoes
I'd say the biggest reasons are 6 and 7. Mixing in air bubbles and the materials in the paint. Also, even the typ of solvent you use to thin the material can have a big effect on the leveling and foam release.
Thank you William, thats a good point about the type of solvent and how it contributes to foam release!
