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?

[@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.

[@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?

[@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!

Great video Lucy. You are truly the master of PMF. I've never seen it done better! Been sending KZbinr's your way to view the build videos :) This was one of the very best collaborations I've ever done...thank you for everything my friend :)

[@thelwood]

Thank you Tom! It was a blast!

[@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!

[@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.

[@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.

[@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!!

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 .

[@thelwood]

Thank you! I have been really happy with PMF on my trailers :)

[@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 :)

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.

You can make an easier camper tear drops are harder you could go with a square back no curves. Kinda like runaway campers just don't copy theirs. 73

[@iMapMultimedia]

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.

[@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.

[@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…

[@1chumley1]

I love it. Beautiful!

[@thelwood]

Thank you!

[@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. Some of the links don't work anymore. Any updates on fabric, and roller covers?

[@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!

[@perfilalmasviajeras7325]

Buen trabajo, me gustaría uno felicidades 😊

[@thelwood]

Thank you!

[@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.

[@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...

[@cirelefebure5485]

thank you.

[@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!

[@pamojja]

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. I also live in the desert so I don't have salted roads and stuff to deal with. Sorry that I don't have more definitive answers to that great question

[@pamojja]

@@thelwoodThanks. I'll report what I find out. I was asking because I temporarily placed a 5-inch thick in front of a broken glass balcony door. Obviously, just a little gas from the double window was enough to melt a dent. Even that thick XPS plate due to that bowed in the opposite direction.

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!

[@biggiebird6887]

Thank you for clarifying that I need to wash and dry the canvas… do I do a straight water wash or is okay to use laundry detergent?

[@meandmyRC99]

That all looks amazing. The work you do to get the cotton flat is awesome. Have you tried any other materials besides cotton? I am wanting to make interior foam a little more durable, and cotton seems like overkill just for that. Anyway, good job!

I haven't tried anything else, but bed sheets should work well for that!

[@dantejones4551]

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!

So people are calling canvas covering PMF? This is what we used on boats since long before frp. It’s cool seeing old processes being rediscovered.

Yes boats and airplanes used to be covered this way! I love the method and I don't know who started the PMF name. I have made 3 trailers this way and they are all holding up wonderfully:)

where can I get patterns for sides, windows, door ect. I wan to make one that looks like a cabin car trailer for my scooter

[@thelwood]

Tom may be willing to share his files with you. However, I suggest the outer grid be enlarged so the roof can go on the top instead of between the walls. These were already cnc before all design elements had been confirmed. Happy building!

Where did you learn about this poor mans fiberglass? I'm wondering if you have done any work restoring vintage railroad cars or know someone who has because this is almost exactly how the roofing is done on railroad cars built up to about the 1940s.

[@thelwood]

I first learned about on a teardrop forum. And from there I just researched the technique, planes and boats used to be coated this way too. And then did small trials to make sure I had it down prior to my first trailer. I have completed trailers with it.

I bet a zero breeze A/C could cool that thing down with just battery power on even the hottest days!
