Eric you know a lot, and I want to say thank you for all the info. I know you put it on the video as text, and I understand it seems less important when you're doing it every day, but proper respirators are MANDATORY when using epoxy. It messes with your lugs really bad and really fast. You want to be doing what you like for a lot of time, so please take care. Thanks again!

Amazing how many actually do not wear masks or respirators to protect their lungs, I have seen so many workshops neglect the workers from toxic fumes. I wear a mask for almost everything, sanding, spraying, epoxy etc......Great advice!

[@rjwintl]

why not just pour a glob of epoxy on an area , smooth it out with a squegee and fine tune it with a better bristle brush (the kind that doesn't shed bristle "needles" in the epoxy ) ???

[@graemevetterlein]

Did part 2 ever happen ?

[@myoneblackfriend3151]

I am going to be putting epoxy on my truck bed. I was just going to stick it in a mold and dump it on there like in those river table videos. I will take your path. Thank you. I've have seen heat guns remove bubbles from newly applied epoxy.

[@vannasiozou6512]

Great video. I would like to ask if you use epoxy primer only if you want to paint the wood. Here, in Greece they told me if I want to see the wood’s natural grain I have to only use varnish. Is that the case?

[@offcenterharbor]

Well, epoxy primer, that might be right. But in this case, with good clear epoxy like West Systems 207 hardener, is a strong and protective baselayer below varnish that can look really beautiful.

[@jenniferhermanson8969]

Well, I realized within the first 2 minutes that this would not be ideal for my project, but I just can not stop watching this guy.

[@donpetrey8007]

Ok here is a question what about using epoxy for my exterior woodwork. I have heard epoxy then ursthane or something but didn’t make sense. I want something that last years with little maintenance.

[@bipedalhominid6815]

Epoxy is not UV resistant. It will "yellow" over time when exposed to sunlight

[@carbarrer6]

I won't pay for part 2. Sorry

[@Bakanelli]

What kind of varnish are u guys talking about? Polyurethane or some classic 100 layer type of joke? As far as I know polyurethane clear coat lasts a number of years and when it finally “oxidizes” you just quickly sand it with 320 grid and apply a fresh layer of polyurethane and Bob’s your uncle

[@davidmanen5495]

Great instructional video, thank you! Would you recommend this process for waterproofing a DIY plywood teardrop trailer or some other method? Thanks again.

I have a lot of experience wthis 5ype of epoxy, tho I only use it outdoors with a mask. You could at least have a fan, indoors. And I've never tried multiple coats of it, I would just do one coat of liquid, then cloth, and then liquid top of that. West system has a booklet on how to use it, which is important to read.

[@mikaelwester]

[@rickmiles9400]

I noticed you were stirring the epoxy with some rigor. How do you prevent bubbles forming in the epoxy?

[@Benniebassdrum]

Great video! I wonder how you keep your tools clean? Like your roller tray for example. Assuming you’re not using a new one for every layer?

[@ryanwurm2674]

What are those pumps called? The variable ratio pumps you used to dispense the epoxy resins…we could use one of those pumps for our shop.

[@TPainWhatitDo]

I bet your shop could make one. Make a hand-cranked peristaltic pump where the same set of rollers compresses two polyethylene tubes of different diameters. Pick the correct diameters and you'll always get the right mix ratio.

[@adrianmaree8352]

Does the 205 turn red because it's older and being very hydroscopic it has absorbed moisture, or is it always like that, even when new?

[@clidelivingston]

can I just seal my boat with resin and not paint over it?

[@nateface]

Clyde - I built a Clint Chase plywood lapstrake rowboat and only used epoxy, no paint. If you're worried about UV protection, varnish over epoxy is great.

[@clidelivingston]

@@nateface okay, thanks!

[@Subgunman]

Are there any colorants available for epoxy? I know from in the past I had to repair a fiberglass ray dome for an antenna that was crushed in shipping. I used two different colors of a dye, colorant for fiberglass resin to match the factory color of the antenna. Looking to make some dock boxes ( aka roadie cases for electronic stage equipment ) but I do not want the added expense of the ABS-plywood laminated panels more commonly used for their construction. I would like to coat with epoxy for surface durability as well as for moisture protection of the contents of the cases.

[@ehRalph]

I learned the hard way using a cheap chip brush for epoxy swimming pool paint. I had to scrape half of a brush off the wall before it setup. I still use chip brushes for lots of finishes, but I wire-brush them when new and also when cleaning the brush for reuse. Epoxy is a once and done. Any wire brush will work, but a fine stainless steel grill brush is a good choice for first use and pulling majority of loose hairs.

[@bradgoliphant]

Helo, question for you. If I have already stained wood with a penetrating stain, could I still add a top coat of lacquer or enamel or something to help give is further weatherproofing? Would it hold?

[@jrob8931]

Not sure I understand why someone would need to “varnish” over epoxy. Can’t clear epoxy be a stand-alone top coat that’s already superior to any varnish?

[@stevenmstone2223]

Epoxy has no UV protection. The varnish provides protection from the sun.

[@offcenterharbor]

Epoxy needs the UV protection of varnish. Left alone, the UV will make it weaken and crack over time.

[@Farmer2492]

Hi fantastic video i have just brought a 15 foot timber top boat the boat top is ply top can i varnish it to keep the timber look what would you recommend

[@nialljoyce6011]

Hey, really excellent video & brilliant detail. I was making up a prototype for a Living Wall (plants) & was considering plywood - plastic (waterproof the plywood) - felt (holding plants). The felt would have to stappled into the plywood. In your experience, does the epoxy make the wood impenetrable (ie, staples/nails can't get a proper grip)? Would staples going into the coated plywood affect the waterproofing? Thanks in advance!

[@offcenterharbor]

Nails or staples would still be able to pierce the epoxy and go into the plywood, but you're right about the waterproofing - any hole is a chance for moisture intrusion.

Is the purpose of the rolled epoxy only to waterproof the wood? Does it make the wood stronger also? Or is the glass or carbon mat needed to add that strength 💪 thankyou

[@jimviau327]

Epoxy provides extra strength coating but barely reinforce the material. Fiberglass or carbon fiber will achieve much higher strength.

Will epoxy resin works on boats

[@markthomasson5077]

Should you thin the epoxy t get a better penetration in the first coat

Check the instructions and recommendations of whatever brand epoxy you're using, but if it's WestSystem, there is no need to thin the epoxy. Just don't use a thickener. Mix it in the ratio called for.

This was a great tutorial. I am about to epoxy our composting toilet for our school bus conversion. I don’t have a roller, and it’s just a toilet... lol so I am going to go with your foam brush tipping method for the whole thing. It also has corners that a roller can maneuver... so I think it will be the best in this case. Epoxy seems like the best solution. Ain’t nobody want to clean 💩 off of a pour us surface. 😆 Thanks for the tips! - Erin + Brian too

[@garywilliams7484]

Funny. I am working on a cargo trailer conversion and had the same thought process.

[@onelinesong4203]

If i would apply my garage door with epoxy ..Will it last forever then?

[@E-Kat]

Depends how long is your " forever"? But seriously, it will last many years, assuming the wooden door is totally dry, and that's not easy to achieve. Also, you'd have to paint the epoxy, then after it's cured, sand it a bit and apply another layer. It's an unpleasant job, requiring filtered mask( best you can afford!) as the dust and fumes are very toxic!

[@jec_ecart]

What is Tipping?

[@stevestone8004]

Using a brush to smooth out the paint or epoxy after rolling it. Rolling is best for getting the liquid evenly spread and then tipping is best for getting a smooth finish. Roll progressively across a surface and keep tipping back into the still wet surface (keeping a wet edge) then the paint or epoxy will settle out after tipping into a smooth surface rather than getting sticky and showing brush marks.

[@ericolson8708]

Thanks for the walk through

[@manmaas]

[@TPainWhatitDo]

Great tips for applying the epoxy clear coat. I don't understand why I would varnish on top of it. Epoxy is hard, varnish is very soft. Epoxy would be the more durable coating. I plan on just waxing it and being done.

[@georgewashington7444]

Epoxy will become severely compromised in presence of any UV. It must be varnished if kept bright or painted to protect it.

[@blackpig52]

Inside that's fine,it's not uv stable so outside it needs protecting
