Hello, A quick bit of advice needed please: We are setting up a brewery South Wales and have taken the space over from an existing brewery - their floor was terrible and had low spots and water pooling, which was bad from a food hygiene perspective. The paint was also flaking up so we decided to start from scratch. The area is 9x9m (81sqm) and there is a drain channel 3m away from the wall which we want to squeegee water into. We wanted to level the floor and apply an epoxy resin cover and new drains. We hired a scrabbler and took the top layer of paint off, swept and hoovered and applied a primer in a 1/3 ratio for the self leveler Primer: https://www.screwfix.com/p/mapei-primer-g-5kg/5309p?_requestid=611890 This dried and then we applied this self-leveling compound: https://www.screwfix.com/p/mapei-ultraplan-3240-self-levelling-compound-25kg/4959f I then called up the supplier of the epoxy resin and they called the manufacturer of the self-leveling compound. They were told the leveling compound we had used was only suitable for laying tiles onto, not painting or epoxying as it is not strong enough. We need to use this Expoxy floor so have no choice other than ripping up the new self-leveling we just laid. I called up another Epoxy retailer and they said it would be fine to use their stuff with a penetrating primer which will soak into the self-leveling and bind it together. This is the package they suggested: https://www.resincoat.co.uk/en/high-build-epoxy/424-triple-garage-floor-paint-bundle.html Can anyone tell me if this will work or is there going to be a problem with not using the correct self-leveling compound? What are the potential problems? What would you do? Thanks
Renovation isn’t a wearcoat, before you do anything get a moisture test done without that info we really can’t give any proper advice. Sent from my iPhone using Tapatalk
The floor will be wet which is why we want to use an epoxy top coat, the self leveling will be protected from the moisture by the expoxy. What would be the next steps to make it work?
The smoothing compound you've used isnt moisture tolerant Hense it will fail so Next step is to remove it
Remove the screed, do a proper moisture test depending on the results you will have completely different ways to proceed. Sent from my iPhone using Tapatalk
My thought was that this screed will never get wet, we are going to lay epoxy resin ontop of it. So it would not matter that this screed is not suitable for getting wet. Is that not the case?
It will be absorbing the moisture from beneath it which will lead to it failing if the moisture levels are too high. Sent from my iPhone using Tapatalk
According to Mapei, this self leveling is designed for tiles or vinyl flooring. Would there be any issue with laying large floor tiles instead of the epoxy resin?
Yes your screed is going to pop if the moisture levels below it are too high, you absolutely need to do a Rh% test before anyone can advise you further. The answer to that will dictate the primers you need and the surface dpm that may be required a test takes minimum of 72hours to take. Sent from my iPhone using Tapatalk
I know why you want the resin floor - as an ex-brewer, up until 5 years ago, I can attest for how damn good it is. But please, please, please listen to the lads above. Make sure everything is right before moving forward. Anything goes wrong with the floor, you can then have issues, with the sitting of stuff like your temp probes and seals and pipework. No one wnats to get covered in neon hot wort...
Do you have any pictures of the floor, before you applied latex ? I would bet its a powerfloat floor, and also that its piss wet through. As others have said above, its pretty much doomed to fail as soon as its covered. Very likely needs removing, maybe blasting, dpm, water mix screed. But, that is a guess, and you do need to carry out the proper tests before you proceed. How many bags did you use over 80 sq m ?
Yes....because you have laid a non moisture tolerant screed on what is possibly a damp floor. It will eventually fail no matter what you put on it. You want to take that chance?? Think about the costs several months later when you have to remove everything sitting on that floor and then remove the screed! Would you use a bed of sand as your foundation to build a house on?
