Hello and welcome to another presentation by LearnCoatings. This presentation is seven reasons why epoxy floors fail. This is quite an interesting subject because epoxy floors are beautiful products and the unique beautiful surfaces but sometimes we have these ugly looking results.
Epoxy floors do go wrong many times and there are several reasons why they go wrong. This presentation is looking at these reasons and suggesting ways to avoid the problems in the future. So, what causes flooring products to fail? Here go the seven reasons: 1. This is in my opinion the most important and the one that just comes up again and again and again. Poor surface preparation: If you are going to coat epoxy onto an old surface, you need to make sure that surface is ready to accept the epoxy coat. You need to grind the surface, you need to clean it, you need to dry, it must be dust free, a lot of time has to go into preparing the surface properly to be able to coat it with epoxies. 2. The second main reason that we have identified is humidity: You need to know epoxy products, they do not bond well with humidity, I’m talking about solvent based epoxy products here. So, when you are coating epoxy on surfaces, you have to make sure that the surface is completely dry. You don’t want any wetness and humidity, make sure there are no pipes or taps dripping and of course make sure there’s no humidity from beneath the ground sometimes in areas near rivers and marshes may actually get humidity entering, may be rising up to the to the substrate, make sure you don’t have a problem there otherwise your epoxy floor will fail. 3. Third main reason why epoxy floors might fail, a weak substrate: This happens when you coat the epoxy floor product onto a low-quality cement what ends up happening is, the cement is too weak and it ends up cracking. So, it’s not actually epoxy floor that failed but it’s the cement beneath that’s failed. And the slide explains that the cement actually disattaches itself from the cement. 4. No primer or not using the correct primer: You must prime the surface when you are going to apply epoxies, make sure you use a soluble primer. The primer helps seal the pores, penetrate the pores, it makes it possible for adhesion and bonding to take place. You want to make sure that this coat is going to bond well with the concrete and the primer will act as an intermediate layer that will enable that bonding. Keep in mind floors experience heavy wear and tear don’t assume that industrial floor squiggled are simply stick to a concrete, so you must make sure that you’re using a primer that will help in that respect. 5. The fifth reason why the epoxy floors fail, incompatible surface: This is quite an important one, it doesn’t happen as often but it’s quite important. what happens here is, the substrate may not be compatible for epoxies; one example is you never coat epoxy on the wood because what happens, wood is a very flexible it’s kind of flexible the material that bends and breaks apart if you try putting epoxy in something that bends, the epoxy will crack because it epoxy is much firmer than the wood, so it will crack. So, you want to make sure that whatever you put underneath has the same sort of strength as epoxy like a strong concrete for example, you don’t want to coat around the wood, you don’t want to coat on a sheet of metal you don’t want to coat it on something that’s flexible like P. V. C. lining. 6. Main reason why epoxy floors may fail, Contaminated floors: This problem is quite common in old installations, for example an old floor of a factory or maybe a car service shop. A workshop where over the years, the floor has been polluted with various oils and greases and all types of chemicals and what happens, if you try to actually coat epoxy on that, you will get a reaction and there will be no bonding can take place. That’s why it’s very important to rapidly clean the surface. Look at this picture here, this was actually an oil factory with lots of oils very polluted and we had to Mill it and grind it and get clean concrete so we could actually pour epoxy over it. 7. Finally, the seventh reason we have identified is the wrong resin and hardener mix: What do we mean by these? epoxy in order to pack systems that have a hardener and a resin. You need to mix the two before you actually apply the product. Now what happens is, usually these comes supplied in prepackaged amounts. And one mistake people make is, they kind of assume that you don’t need to weigh exactly the proportions of the A-component and the B-component. They just think all of this mixing together they’ll be fine, that is actually a wrong thing to do. Make sure that you are mixing the product according to the specified proportions.
Also, make sure that you’re mixing the product with a real electrical mixer. Some people think they can just stick a stick and mix the product like that, it will not work. You need an electrical mixer that’s powerful enough to create a uniform mix and a uniform mixture throughout the bucket. What ends up happening is that, your proxy will be sticky if it doesn’t cure properly you may end up having a wrong proportion of the resin versus the hardener and their epoxy might be sticky, it might be soft and it will never ever cure. So, make sure you don’t ever get that mixing wrong. Basically, just follow the instructions and mix it properly. Those are the seven reasons I just described. Thank you very much for reading.
