Poor Mans Fiberglass PMF Tutorial, Tips to get PERFECT Corners! Foamie, Vespa Teardrop

[@snicketysnickerdoodle8484]

Your PMF technique is the definitive method. Lots of videos out there demonstrating awful end result. A stand alone PMF how to series would help lots of folks out there. Thanks for sharing.

[@thelwood]

Thank you so much!

[@khelek100]

Do you think using Foam Fusion instead of tight bond, would change the canvas adhesion much?

[@patrickkenney1080]

Back in the 30s, Rosco Turner, a very famous air racing pilot used this same technique on his 300 mph race planes-however they were using Grade A cotton. Kudos to you for keeping this skill set alive!

[@thelwood]

Thank you!

[@usedcarsokinawa]

I’m almost sold on the idea of poor man’s fiberglass. It will give me the ability to make my first small camper.

[@SheepHaterUY]

Serious ASMR watching you iron those edges down (pleats smaller and smaller). Love this!

[@thelwood]

Thank you! It is satisfying to do!

[@SheepHaterUY]

@@thelwood I use it often in my sewing. I can be seriously OCD about it, or rush through it either way Lol

[@PainterD54]

Titebond 2 is only water resistant where as Titebond 3 is actually waterproof and lays down just as well as Titebond 2. It is just a bit thicker and the first coat (before you lay the cloth) can be deluted with as much as 50% water, but I go with only 1/3 water and 2/3 glue.

[@thelwood]

Thank you for the informative response! Perhaps if I watered it down some I would like the way it rolls out better. I use TB3 for somethings, for PMF the multiple paint layers are what really seals it up. My 7 year old trailer is still perfect looking. But perhaps I will try TB3 watered down so I can get a nice thin layer like TB2. :) cheers!

[@kevinswanson3910]

Could I mix primer with the glue?

[@rawhide154]

You make it look so easy;)

[@thelwood]

Thank you!

[@leeharrison8790]

My biggest error I did was stretch the cloth lol you are so right about not stretching the cloth it causes air pockets but still no failures ... I did use a stiff paint brush & dabbed the cloth tapping it with the stiff bristles of the brush like folks do with actual fiber-glassing the cloth to get out air bubbles & tight places .. I seen you used a iron .. way cool ! I'll have to use that method !

[@thelwood]

I am happy yours still worked out well! And good idea with the paint brush!

[@meandmyRC99]

Not stretching it tight is counterintuitive I think. If I hadn’t seen this, I would be pulling it tight.

[@TueriNatura]

Excellent! Thanks for the tutorial and showing the details. I am starting a project using the PMFG on a truck camper inspired by your trailer video. Thanks for taking the time to show us how it's done.

[@thelwood]

Thank you! I am sure yours will be beautiful!

[@chuckwilcox6997]

Excellent Lucy, inspiring to see how well the PMF turned out and the clear detail on how to apply, glue and paint to get a smooth finish, inclusive of the preparation of washing and pre-ironing tips. Awesome work on the edge, pressing out the pleats to zero, I didn't know that could be achieved.

[@thelwood]

Thank you so much!

[@samTollefson]

Very interesting tutorial! Starting in the 80s, I had a property management business taking care of large estates on the ocean on Jupiter Island in Hobe Sound, FL. One of my places had a huge deck over the beach looking out at the ocean that was covered with PMF, there were about 1" overlaps at 8' widths with a double row of brass tacks spaced every 1/2" holding the seams tight, I think that was the key to the long life, not letting any separation get started. Every couple of years I would paint it but it just lasted and lasted in all the sun and salt air on the beach! The house was originally built in the 40s and I moved on after 25 years in the mid-2000s. I am sure it is still there if the place has been properly maintained, amazing stuff! I don't think fiberglass would have lasted near as long as it would have separated from the wood and developed blisters, the canvas and paint allowed the covering to expand and contract a little with the seasonal changes. I believe it was the best choice for covering a large deck like that.

[@thelwood]

That is awesome! It is really good stuff when properly applied and maintained!

[@Tonisuperfly]

I’m trying to picture a deck like that, as I don’t have any reference. Our decks are always made out of wood slats here. Was this pmf covering wood sheets? How water drain off it? What colour was it? Thanks

[@samTollefson]

@@Tonisuperfly The place was built by a millionaire in the 1940's, I don't know what the actual decking material was but I did have to replace one of the stairways to the beach and it was made of teak so I suspect the decking was also made of teak. the deck had a slight grade to it, when the large picture windows were washed the water ran off the outer edge. In the 25 years I took care of the place all I ever did was clean and paint it every 1 or 2 years, the edge where it connected to the house was flashed with copper flashing like any roof situation. It was painted gray.

[@Tonisuperfly]

@@samTollefson excellent. Thanks for your description. Your memory is outstanding!

[@samTollefson]

@@Tonisuperfly Thank You. After thinking about it, there is something I would like to add. The decking, I am positive, was tongue and groove planks not the gaped decking boards we think about today, as there was no separation apparent anywhere. The deck would have been sealed and a type of glue to adhere the canvas to the deck, it would not have been hide glue as it gets hard and brittle over time. I wish I knew the exact method used but I believe it would be very much like the PMF method people have been resurrecting today.

[@RecordingStudio9]

Thanks. I need to learn more about PMF and this has been very helpful.

[@thelwood]

You are very welcome, I hope you have fun making something with it!

[@bookman106]

You are welcome! Thank you!

[@triker53]

How about a cycling camper trailer? I like the use of the PMF, nice job

[@thelwood]

Thank you! This could definitely be pretty easily modified down to a cycle trailer 😃

[@TheBeardedDog]

Very good tutorial. As for the strength of PMF, I have a crazy story. I built a teardrop with a sandwich of luan on the inside with 3 layers of 3/4" foam and PMF on the outside. I had the unfortunate luck of being jarred awake one night while camping on the beach. I was awoken when a truck side swiped my trailer. Luckily, the only damage was paint transfer from the truck and my rear rack was a bit bent. I feel pretty fortunate to come out unscathed. I am not sure how the trailer would have faired if it was plywood sides.

[@thelwood]

Wow!! That is amazing!!

Very informative thanks. I am building my own modular trailer and am thinking of using the same technique. One concern I have is how to secure hinges (I will have a few because its modular) to the foam/glue/canvas body? I have some hinges that do carry a bit more weight than a door. Did you bolt through with the hinges or simply screw them on? Would you recommend additional trim work to better fasten the hinges? What has been your experience? Any info would be much appreciated.

i loved it gunna build one my self now lol or buy one for a 60 day adventure lol

[@leeharrison8790]

Wow .. thanks for sharing your method .. it was great to watch your process ! I used wood glue over thin skin 1/8 plywood like you did .. but I used cotton bed sheet that worked out great for my project . I did however use the wood glue thinned down to saturate the outer cloth once glued to plywood instead of reduced paint & after it wasn't tacky I introduced the latex paint layered the coats on to build up the finish I was looking for .. with that thin cotton bed sheet I brought at the second hand store it came out great just like a air plane cloth & doped sanded & finished with paint ! It's amazing how will it's holding up exposed now over two years to Florida weather extreme hot sun & extreme rain ..lol I sure was surprised how well it's doing !

A recommendation for pulling your pleats is a mini set of needle nose pliers. A slight twist and tug works really well, especially if the material is wetted out. Good work . I’m looking at building a light weight trailer for a drag and drive setup , I will probably be going the same approach. Good job !

[@BlueRidgeRider]

100 years ago this is how most aircraft were made, minus the foam. A tubular steel frame was covered in cotton and painted with a flexible paint called dope. The base layer had aluminum powder. The thought was it would protect the cotton from sunlight. Then the final coats were the color. The dope had the added feature of shrinking when it dried so it removed any minor imperfections. Unfortunately, even with all the precautions cotton didn’t hold up well to the elements. Also the dope was made with nitrocellulose which is extremely flammable. A few years later someone figured out that Dacron lasted a lot longer and didn’t require that dangerous dope. Any imperfections could be taken out with a heat gun. The final evolution in the cloth covered airplane was to use fiberglass 😂. It was expensive and somewhat heavy but it would last the life of the plane. In fact it’s major drawback was the parts of the plane that normally got inspected during a recover job were now hidden permanently 😮 Anyway, I thought you would find this interesting. Thanks for these great videos! You are giving me ideas😅

[@thelwood]

Very interesting! Thanks for sharing :)

[@steveburns6628]

Your camper looks great! Some recommend glue below and above canvas. Did you apply second coat of glue? Once again, your project looks great.

[@BLACKF1R3OFFICIAL]

I'm going to be building one of these Foamies for my 500 watt EBike here within the next week or two. Your timelapse video, and this video have both inspired me, and informed me that I don't need all of this extra stuff for PMF. Which is both a relief and a money saver. I will be purchasing most of my materials from Lowes. Also, I am getting 5 sheets of the 4ft wide x 8ft long foamboard. P.S...your adhesive glues video was the first video I watched of yours and have been a subscriber since that video (2025). Hello from Orlando, FL. Question: Will PMF be humidity resistant? I do live here in Florida and our humidity and hot summers are horrible lol ..... And yes, I am a professional stagehand, musician, digital graphic designer, website designer, and self employed entrepreneur. 😁😝

[@thelwood]

@BLACKF1R3OFFICIAL I am no expert on humidity since I live in the desert :) that said, it should be! The technique used to be used for planes and boats, so it should hold up well! Enjoy your build!

[@robertschulke1596]

Exterior latex paint is made to weather away like chalk over time in order to keep the exterior of a house looking fresh. You might consider interior gloss bathroom paint. It is much harder and less water permeable.

[@thelwood]

Interesting idea! I would be interested to run trials of both!

[@meandmyRC99]

The toughest test is time. Interesting idea though.

[@SgtBrewdawg]

Very informative and very cool! Thanks for the insight and instructions. 👍

[@thelwood]

Thanks! Happy it was helpful!

[@altaloma7789]

So many questions. On other how-to videos they apply a layer of glue to the outside of the canvas, then move to putting on the paint. You move directly to paint on the canvas. I suspect the glue layer to be somewhat hydroscopic (soaks in moisture from humidity), but I'm curious why the difference between methods. I'm also curious about your cure schedules for glue and thinned paints. Any guidance?

[@thelwood]

I have seen people use glue over the canvas. I have done 3 trailers with the more "original " pmf (or what i can seem to find of it anyway) of water diluted paint. The diluted layers really absorb deeply into the canvas. The areas where I have had too much glue and it seeped through the canvas were harder to get the paint to really adhere to. 1 of my trailers has been outside for several years and it is still in perfect shape. You could do trials of both techniques side by side to see which you like better. My concern with the glue method would be sanding off the paint in between coats (if you are looking for a nice smooth surface) . Thanks for your question!

[@chrisdennis5362]

You and your friend have inspired me. I have been looking for a trailer for me and the dogs to travel in on my CTX1300. Now I want to build a foamy like this. I would like to know how you attached the floor and some basic dimensions of this trailer. I look forward to following you further projects. This has been very enlightening for me.

[@thelwood]

Thanks! The base trailer is 72"×40". The wood for the floor was attached with construction adhesive and screws and then carpet adhesive was used for under the carpet.

[@bookscienfuegos1122]

This is such a great video as I am reading different comments on whether the PMF can create a nice finish or not. You really show the practical details needed to make it work. I was wondering if you have tried using a paint sprayer, the type that does not need a separate compressor. I was going to experiment this but thought you might have tried or know others who did. I am making a larger foamy so any time savings on the painting would be wonderful. thank you again!

Thank you! I have not tried a sprayer but it should work pretty well

Thanx you showed me more than other vids

[@ruthdoyle9085]

Indoor or exterior paint works fine for first few coats... you can also use paint instead of the glue... basically does the same job...

[@Threeheadsrk]

I keep seeing people applying a thick layer of glue to the canvas afterwards. I’m with you on letting the paint absorb in rather than just paint sitting on glue

[@AlexT-md9df]

I have a Suzuki sidekick that only allows me to pull 1000 lbs max. I’m hoping to make a slightly larger version of this

[@doug759]

just came across this. the PMF coating looks great, the whole trailer looks great. Do you water down the glue as well? and how many coats of paint did you end up using ? also, what are your thoughts on using bed sheets for the cloth?

[@thelwood]

I don't water down the glue. I do 50/50 coat a 75/25 coat and 3 full coats sand between. Bed sheets will work, but I like the thick protection from the canvas. Happy building!

[@danemmerich6775]

Great video. I see a lot of people putting another glue coat over the Canvas. Is that a wasted step or is it even extra protection? I am going to PMF my Camper Build because it is cheaper, but I don't know if I should install the glue on top of the canvas, sand then paint? What are your thoughts Lucy?

[@thelwood]

I prefer to not have an extra layer of glue so the paint can soak deeply into the canvas. I have an 8 year old and 5 year old trailer in perfect shape still using this technique :)

[@danemmerich6775]

Nice work do think this is easier than using epoxy and real fiberglass? I worked with epoxy but its very expensive . Just wondering since you have done both? TY

[@ruthdoyle9085]

An alternative is using latex paint in place of glue and bedsheet in place of canvas. Paint the foam, apply cotton material while wet and repaint cloth. Total soaking of material. Then repaint until material texture disappears… fiberglass screen also works and is very strong. As long as you repaint every 5 years it should last a long time…

Hi there, I have the budget for epoxy fiberglass on my next project but I was wondering about the maintenance with PMF. I will be using it mainly in the winter and the roads and salt have me concerned about wear. I have been wanting to try it out as its nicer in the shop and I dont need a mask.

[@thelwood]

The low fume application is what appeals to me too. My PMF trailers haven't required any maintenance, but I do not have to worry about salt here in Arizona. You might be best served by epoxy fiberglass! I loved in Minnesota so I knew how fast salt can eat through anything!

Thanks for your excellent tutorial. How have been your experiences in the long term concerning the resistance against solvents? Does the PMF layer prevent accidental exposure, for example at gas stations, from diffusing through to the XPS, and therefore damage? Thanks, and best wishes.

[@thelwood]

Thank you! The PMF has held up really great on my trailers. However, they have had low exposure to solvents. That is an excellent question. Airplanes used to be coated in it.

[@bellrobert1978]

When you say exterior paint do you mean for timber or masonry?

[@thelwood]

I have always used timber paint like house paint

[@tonyhardy-kp4os]

I learned from watching your other video when you were testing what glue works best for adhering foam to foam, that the wood glue don't work very well. So i watch this and assume the wood glue must adhere good enough to the foam or else you would probably not try it without testing a smaller piece like you did when testing the foam to foam adhesion, unless i missed that video. I mean we already know the wood glue works good for wood to cloth but we never used it with foam to cloth. That makes me question if it would be better to just use fiberglass, maybe i need to test some small pieces myself. It cost a little more but it could be worth it. a gallon of that wood glue is already 25 USD anyway.

[@thelwood]

@tonyhardy-kp4os excellent observation! I did trail this, but not make a video on it. I roughed up the foam and the wood glue held the canvas on well. However, you are correct about fiberglass. For a foamie, real fiberglass would be the strongest!

[@chloemakesthings5380]

Hey Lucy, we are about to start our camper build, do you think it would affect the strength and or look if we joined two pieces of canvas on one side? our canvas is 5meters long and its really hard to find seamless canvas at that size.

[@thelwood]

It will be fine from a strength standpoint. I think you can find a creative way to cover the seam, or get creative with the paint job to incorporate it :)

I'm just trying to figure out if it'd be possible without having it already mounted on the walls somehow.

[@thelwood]

Great question! I just did the side walls not the ceiling! That would have been a pain... lol

@@thelwood Yeah, I was having trouble imagining being in there upside down trying to iron out wrinkles and then applying the very drippy paint. :) One other question, I was wondering about using 4oz cotton for a bicycle trailer to save weight rather than a standard 10oz, which would save about ~10 lbs. Do you have any experience with other fabrics and if/how they work?

[@thelwood]

@@smg604 I have not worked with lighter fabric, but I would think it would work. I would do a small sample and see how it feels

[@chuckwolf3221]

Have you ever tried spraying instead of rolling?

[@thelwood]

No I haven't. It would probably work well for the final coat. But I am not sure if enough would get deep into the canvas for the under coats.

[@chuckwolf3221]

@@thelwood Thanks you are correct I believe.

Hello again I'm doing mine over plywood. What grit sand paper would you recommend using before gluing ? Cheers

[@thelwood]

120 would be good

[@warrenbenton9033]

@@thelwood Thank you.

How rigid is the trailer after applying the PMF (especially after the kerfing)? I'm going to start a project and I'm wondering how much extra bracing I'm going to need.

[@thelwood]

Hi Dante, the sides without the kerfing are very strong. For the roof it definitely needed the wooden dowels as spars to help strengthen it. If it were going to have to withstand snow on the roof, I would also put 1/8 baltic birch over the top. Here in Arizona that isn't an issue. The sides were cnc cut before I had input on the design of them, the area by the door was very thin... only an inch of foam above the door! So there wasn't room for wooden dowels there. To strengthen that part I actually put 1/2" x 1/16" aluminum bar right into the kerfs on each side of vent using exopy. That added a lot of strength!

Hey! If I have a bunch of exterior primer would that work as the fist 50/50 coat? Also how long did you wait on the glue before paint - thank you!

[@thelwood]

That will work very well! I leave it over night before painting

[@MelissaSher-yr8mq]

Thank you so much for the reply - love your videos!

[@indigo196799]

There are many weight of cotton canvas drop cloth available. from 8 to 18 oz. Which would you recommend? The thickest the better?

[@thelwood]

I use 8oz and it is plenty thick and easy to work with

[@JessicaHarris]

So there was not a layer of glue on top of canvas too? A lot of videos out there layer on glue on top of the canvas before the paint...

[@thelwood]

@JessicaHarris some do that. My process is like how the boats and planes used to be done. I have never tried the glue over canvas technique so I can't directly compare them. However, without the layer of glue, the paint is able to absorb deep into the canvas. It is very strong! With the glue on top, my concern is that the paint could chip over time since it is sitting on top and not deep into the fibers. But i haven't tried it that way, so I can't be certain. I do know that I have a 9 year old trailer in perfect shape using this technique .

[@JessicaHarris]

@@thelwood excellent! Thanks. I was thinking the same about the paint… going to give it a try!

[@russellesimonetta9071]

Uhh titebond lll has a longer working time but ll is fine! Finish with outdoor latex paint and it will last and last!

[@thelwood]

Yes it will! I prefer the consistency of TBII for rolling it on :)
