Can we apply Epoxy Outdoors? Is Epoxy UV resistant?

- In this video I explain the main reasons why Epoxy should not be used outdoors and why it is not UV resistant.
I also explain that if you want to waterproof a rooftop you should use a flexible product instead that has better resistance to UV
Important Note: Polyurethane Clear Coats are not suitable to protect epoxy when exposed to the sun. They have been specifically designed to protect PU coats.
Very informative!! Thank you
I have an art piece table, its 4'x2'. It is an antique, the artist created a 1/2" thick clay fired mosaic into a table by gluing the clay mosaic to a cement slab 1/2" thick. After restoring it, the clay mosaic was all in pieces, the cement slab was intact though. We attached the cement base to a 1/2" plywood. The top was uneven, I poured a table top grade epoxy resin over it to flatten it out. The customer keeps it out in their screened in porch that is cold in the winter, in NH, so it gets down to 20 degrees. I know now that I should not have used this product for where they are storing it, but there is no way to remove it without damaging the artwork. The epoxy lifted on the sides from the mosaic when it was cold. Once it got warm out, I glued it down with clear gorilla glue which can take the cold. Is there anything I can clear coat it with that you can think of that can work for these conditions? Any suggestions?
Decorative epoxy, is not really my thing there are several UA-cam channels that cover this space. You may want to ask there
Thank you. What’s the different between Epoxy and resin??
There are many different types of resins used to manufacture coatings. Epoxy is a type of resin used. Epoxy resins cure together with a hardener
I am from India. I am using 2 component Epoxy system having 80%elongation for concrete roof Waterproofing purpose. As a top coat I am using white 2 component PU over the epoxy coat surface, to protect the surface from UV as per manufacturer recommendations.
Please advise
I am not familiar with the exact products. Epoxy with 80% elongation means it has probably been modified with plasticisers, I am not too keen on such products. When talking about roofs pu clear coats should only be used on pu waterproofing coatings
Great video ! One question... what would you use to waterproof an exterior painted concrete wall ? Something very durable and weatherproof (in Canada).
I was looking into Stormdry but it does not penetrate painted walls. Thanks !
Most exterior based walls are coated with acrylics, if you are looking for something more durable than your standard acrylic wall paint you may want to look into solvent based acrylics. These are far more durable and have better long term adhesion than water based products
I wonder what impact will the UV exposure will have on the slab just outside the garage door. It gets about 4 hours of AZ sunlight a day. I would use a 100% solids epoxy with a heavy coat of color chips and Devoe HPU. They advertise this HPU as aliphatic polyurethane
The area outside the garage door will definitely start showing some yellowing. The flakes and the HPU will definitely help in limiting the yellowing and chalking. But the light can go right through transparent coatings whether they are UV resistant or not
Are Aliphatic PU and Polyaspartic the same? If not, what Aliphatic PU would you recommend for the USA for an outdoor stamped concrete deck, if you only ship large quantities?
One question: what if ia pply epoxy with a poly top coat on a covered patio? No direct sunlight but still outside. Will that work?
I painted a yard decoration with Rustoleum Appliance Gloss White Epoxy paint. Going on two years now and it looks fantastic. Please explain.
How come they apply west system epoxy on teak on boats and then add varnish for uv protection? Is this simply a matter of keeping up with the varnish?
In the US the term epoxy is used for everything, even though often the chemical composition is not epoxy. So its most likely something else that they are using
In my country wher the temperature reaches 50, even mountains are not uv resistant!!!!
What are your thoughts on using polyaspartic aliphatic urethane for flakes system in driveway,patios outside concrete? Thanks you
polyaspartic is good for outdoors since it is UV resistant and has good behaviour. As for flakes systems outdoors make sure you have a smooth surface otherwise it will pickup a lot of dirt outdoors
how long will the polly last outside
With regards to su exposure it tends to last many years, usually it will need re-coating because its gathered dust and dirt over the years
Informative vedeo.
Finally someone who speak the true about expoxy for outdoor use... mny well know UA-cam seller guarantee product is for outdoor use maybe for 1 years but not last.... great contents maybe if you covers after each use probably will last but the season changes will be cracked.... I am not a expert I looking around recommendations for custom project
excellent video. The exact information I was looking for.
Glad it was helpful!
Great job Akis. We are learning alot from this platform.What of epoxies applied indoors but at the reception area with sunlight filtering in? I have seen a lot of yellowing in these areas.
Would the epoxy, pigmented with leafing aluminium, withstand the UV effects if I were to paint a metallic structure outdoors.
Thanks Jesse, yes areas indoors that get sunlight will get some yellowing especially if the colour is white. As for your question I do not think that the aluminium is enough. The epoxy chains will breakdown in the sun regardless of the pigment
Can it be applied to an outside bar top that is under a overhang but in freezing temps in winter?
If you have freezing temperatures you definitely need to work with a polyurethane that tends to be more elastic than epoxy. So yes with aliphatic Pu there should not be a problem
Is aliphatic poly the same viscosity as epoxy? I want to cover an outdoors wood table top. Can I use aliphatic poly for that? Thanks
Aliphatic polyurethane tends to be higher in solvents which means it should not be applied as a thick coating. If you apply make sure the coating is thin
@@learncoatings-epoxyfloorin9448 Where do you find aliphatic caulking? I haven't found any
what do i need to apply epoxy to a concrete patio/deck in the back yard?
You should apply an aliphatic Polyurethane that is resistant to UV exposure
What product do you recomend instead to use acrylic or exposy for outdoor use... winter rain and sun...
Polyurethane based coatings are better for outside. Especially aliphatic PU
@@learncoatings-epoxyfloorin9448 would PU product be suitable for use on a asphalt driveway?
What about to used in garage how long to turn yellowing?
It won't go yellow in the garage as the sunlight it gets is probably very little. Perhaps if your epoxy is white or very light colour then it show slight yellowing
@@learncoatings-epoxyfloorin9448 thanks you!
Where do I buy Aliphatic PU from?
From the same companies that provide epoxy paints and waterproofing coatings. You can have a look at our product here, but outside of Europe we can only ship large quantities

Hi sir, can you please advise on which coating to choose to water proof the interior walls of a concrete water reservoir?
Both epoxy and polyurethane can be used but if you are looking for potable water very few products are approved as food safe. Also always wear a mask when coating in reservoirs there is no oxygen in there and the solvent does not evaporate
@@learncoatings-epoxyfloorin9448 thank you. It was indeed for potable water. 🙏🏼
Thanks so much for valuable information, useful..
You are welcome Fouad!
