Epoxy vs Polyurethane Flooring: Understand the differences
Epoxy vs Polyurethane Flooring: Understand the differences

Welcome to a new video, today’s subject:
Epoxy versus Polyurethane floors; this is a question I get a lot, “What are the differences
between Epoxy and Polyurethane floors?” I mean look at these two pictures here one
has been done with an Epoxy floor, one has been done with a Polyurethane floor, do you
know which is which? Someone who has experience, if they go close
up, they can probably tell the difference but most of us cannot tell the difference
and more importantly, why do we select Epoxy or why do we select Polyurethane? This is the subject of today’s presentation
so let’s go straight and look at the main reasons why I would select one or the other. Now, very important point before we go on,
in this video, I am talking about industrial floor coatings. There are many other applications like rooftops,
sports surfaces, metal surfaces; we’re not talking about these today. Today, we are simply comparing industrial
floor coatings, Epoxy based and polyurethane based. We’re going to look at the basic differences
another important point because some people need to remember that there’s many different
types of Epoxies, many different types of polyurethane floors; Today, we’re looking
at the basic differences to the two What we’ve seen in the industry over the past few years. So, we are first going to look at the OPERATIONAL
DIFFERENCES: These are differences that are based on how these two types of floors behave
when the floor is in operation. So let me give you an example, the Epoxy floors
tend to be harder than polyurethane floors; they have a higher compressive strength and
impact strength so that’s one of the reasons why we do prefer Epoxies in heavy duty facilities. Here is an example of a warehouse where we
have an Epoxy floor; was one of our own projects here completed. So, just a few examples; Epoxies are preferred
in warehouses, they are preferred in heavy industry logistic centers. Any facility with heavy forklifts, Epoxies
are much better behaved than polyurethanes in this specific case. Now, another operational difference is as
we said, Epoxy is harder polyurethane floors are actually softer and elastic, now this
can be a good thing (1) because polyurethane floors are softer, they have a much better
resistance to scratching because they kind of absorb the impact rather than just being
forced on the other surface and because they are elastic, they can also work in low freezing
temperatures. Here is an example of a polyurethane floor,
we did this for a car park will talk more about this car park later on but polyurethane
floors are preferred in carparks for several reasons. And let’s see now where you’d most likely
see a Polyurethane floors, you would see polyurethane floors in spaces with foot traffic because
it’s softer more and more friendly towards pedestrians. You will see them a lot in mall car parks
and why is this because the water PU layer is elastic the layer is elastic, so it works
better in a car park; if you have many floors where you want to make sure that each floor
also waterproofs from the floor beneath that’s why we would prefer polyurethane. And we also prefer polyurethane floors in
freezing chambers because Epoxy cannot withstand -30O Celsius Polyurethane can, so polyurethane
is much more suitable for freezing Chambers. Also we tend to see polyurethane as a top
coat so we put the polyurethane as a thin top coat to pretend scratching; these are
the operational differences; Now let’s go down the slide a bit. Another difference between Polyurethane and
Epoxy floors is the chemical resistance. Did you know that for certain types of industries
we prefer Polyurethanes, a great example is dairy production. Milk, yogurt, cheese production; these floors
are exposed to lactic acid and from chemical experiments we see that polyurethane floors
are much more resistant to lactic acid than Epoxies are. So, for these types of floors, I would definitely
prefer the use polyurethanes. However, there are also other industries where
Epoxies are preferred. Another example of sulfuric acid, if you’re
working with battery production for example, Epoxies are much better. If you put a polyurethane floor with sulphuric
acid, let’s just say it won’t look very well or good after a while. What we always recommend is check with the
manufacturer of a product if you have a strange chemical that your floor will be exposed to;
always make sure that the type of floor you select is suitable, very important to check
for these chemical resistance characteristics Now, let’s go to the APPLICATION DIFFERENCES:
Here, we talk about when you actually apply Epoxy or you apply Polyurethane, what are
the differences? Is it exactly the same thing? Well, let me start by saying “No, it is
not” and just because you might be experienced in one type of floor coating it doesn’t mean
that everything will work out in the other type; these are different types of floors. Polyurethane floors are more sensitive to
moisture have a look at this picture, look at these little, little bubbles. This is what happens when moisture attacks
a PU floor when it hasn’t been cured, this happened to me, I’m not very proud of this
this was a floor which we did in the winter time, we hadn’t realized that moisture, the
high amount of moisture in the atmosphere would actually cause this problem on the floor
the next day. This is something that if you do it with Epoxy
you will not get; if you do a floor with high motion Epoxy? Yes! You may get some discoloration, you won’t
get the best result. I still do not advise doing it but you will
definitely not get all these little spots and all those little explosions because that’s
what happened exactly. So, just to summarize what I said, Epoxy resins
are also sensitive to moisture but the damage done will be limited to maybe discoloration
or blushing. When you are working in an environment where
the presence of humidity could be an issue, always work with Epoxy, I do not recommend
Polyurethane. Here’s one more example, this was a Polyurethane
floor we did and some water dripped from the air conditioner and it landed on the PU floor
and the next day, look at what it did, like it wasn’t even like a little blotch it was
just a little reaction, total reaction because water is not supposed to interact with polyurethane,
this polyurethane resin. Moving on to application differences, Polyurethane
floors actually do have a massive advantage over Epoxy and have a look at this little
clock here, we can make polyurethane floors so we can extend or limit their pot life,
their re-coat time as well as a total curing time. Now, in case you don’t understand what I’m
saying, what I mean here is as you know, when you apply a floor coating, you have to wait
several hours or several days for it to be ready for operation. Polyurethane floors, you can apply a coating
in a few hours, you can re-coat it and the next day you can tell the customer, “Here
you go, you can go ahead and use it” this is not possible with an Epoxy floors. Epoxy floors needs 7days to cure. So, you’d have much more days required to
complete a project than with polyurethane. So polyurethane floor, not all that you obviously
have to speak to the manufacturer but many PU resin based coatings can be modified so
that pot life will be very limited. And as I mentioned here, this flexibility
means a contractor can complete a PU resin floor much quicker and turn it over to the
customer in a short period of time. Epoxy floors will need 7 days. And I just want to go through this example,
this is a car park we actually completed this car park in 4 days and the customer was able
to use it. He gave us the car park on a Friday and by
Monday afternoon, we had finished the project and on Tuesday the cars were like back in
business. What we did here was, you could not do this
with Epoxy floor there’s just not enough time to complete all the stages of priming
and applying the first coat, the second coat, filling up the graphic doing the demarcations
and making sure that it’s ready for traffic. You cannot do it in 4 days; you cannot do
it with Epoxy, you can with polyurethane. Some more pictures here, we completed floor
and we even did the demarcations on time which if you think about it, we actually had to
wait for the floor dry and go back and do the lines afterwards. A lot of stuff got done in 4days. As a final comment, I just want to say that
polyurethanes are harder to work with as I just showed, limited pot life means they also
cure very quickly. So, it’s not as if you have half an hour forty
minutes to apply a pack; some Polyurethanes may be curing in 15-20minutes. So, you need to be aware of that. Also as we said, the humidity is an issue
you have to have a very well trained staff; personally I avoid supplying polyurethane
resins to people that are not experienced, I prefer to only supply experience contractors
who knows what they’re doing with these products. Epoxies are a bit more flexible, a bit more
easy to use. That’s all for this presentation, if you enjoyed

    Thanking you for shearing your good knowledge . Appreciate
    Nivantha – Sri Lanka..

  2. Jesse Sifuma says:

    Enlightening article there. The hardness of epoxies lends from its closely spaced 2 different functional groups-hydroxyl and oxirane ring-, affording dense packing, but at the cost of flexibility.

  3. Tom Sikes says:

    How does one determine if a coating already down is either Epoxy or Urethane.Sometimes I and colleagues are asked to clean coated floors and we have no idea if it is epoxy resin or Urethane resin, unless the owner knows. We are working blind on these surfaces making a best guess on chemical then pressure adjustments on our "spinners"to avoid stripping materials along with the vacuum out. Thanks for your input.

  6. Johan Breytenbach says:

    We manufacture and apply Polyurethane coatings to a varied market on numerous substrates from steel, fiberglass, aluminium, wood and even areas such as gym floors with huge success. it offers a much wider versatility than epoxy in low to medium traffic applications with costs almost half that of epoxy

  7. Dave Larson says:

  23. dcsphil says:

    Hi. So far the best educational & informative video I found on this subject. I do have a question, however, and it sort of lines up with Tom Sikes question below. I've been asked to clean and recoat a church's floor. On close examination I can't tell if it's epoxy or urethane and the existing members have no clue either. The only thing I know for sure is that the floor was done nearly 12 years ago and has certainly withstood plenty of activity and foot traffic. The maintenance man buffs monthly and gets a fair amount of shine back but not nearly what it used to be or desired. I believe that a good clean and scrub with a recoat would achieve great results but my question is which one would I use as a top recoat and are there any problems if I applied the wrong one? In other words, can epoxy be applied on top of urethane or vise-versa? Thanks for your answer and help.

  29. Vrh Luđe says:

    Hey, i have a quick question;

    I want to put epoxy or polyurethane on the floors in my flat.
    I live in a place where there is no moisture, there's always an decent air-flow coming through out the flat.
    Also, flat is located in a place where there is barely any sun, specially on that side of the flat where i want to place epoksy/PU.
    I want to place epoksy/PU in the living room & kitchen!

    The only thing i have concern about is my dog!
    I don't know if his nails or general walking through out the house can do any damage.

    So my question is;
    Based on these info's i just gave you;
    What do you recommend me to do ?
    Put epoksi or PU or none of those ?

    Please help me out, i'm really struggling with what to do with these type of floors.
    I really like the designs and strenght of them but i'm afraid of potential CONS that comes with it so i hope you can give me few advices based on the info's i just gave you.

    This is my email account if it's easier for you to write.
    I'm even willing to pay you some money for your detailed explanation and advices.

    Anyway, thank you so much in advance for every help you can provide!

  54. Gabriella d'Unienville says:

    What about tire staining on epoxy floors ? I understand that tires require ozone protection. The para-phenylenediamine used as anti-ozonants & anti-oxydants are due to migrate within the tire so that the external face of the tire keep getting these supplies to protect the tire. Then, if you leave the car on the époxy floor for too long without moving, you obtain staining Inside the paint. Thing I Don't understand is if this can occur when the epoxy paint is fully cured. Any idea anyone ?

  57. mina rosa-diaz says:

    I’m at an impasse, I am doing a copper penny design on my cement floor and will then do the rest of the floor with brown paper bags.
    I live in the tropics up in the mountains where there is more trade winds but, it will always be humid. My plan was to do 7-8 coats (1 coat every 3 hrs) of the water-based Verathane polyurethane for my floors (765sqft) and over the pennies but after watching your video I’m not so sure.
    How will polyurethane react over copper?
    Should I have fans on during the whole coating process? Can I coat the pennies with epoxy and then when cured poly? And if so, what’s the process and what kind of primer between the epoxy and poly?
    I’m doing this all by myself. I have no help😳
    Any advice would be so appreciated.
    Thank you.

    You must be referring to polyurethane coatings. Polyurethane mortar screeds, even flowable (4mm thick, are much stronger than any self leveling epoxy even as thick as 4mm(which is not worth the price vs a PU mortar screed). Only benefit for epoxy then is the colour retention
