CHEAP RV Fiberglass Delamination Repair Video 

I have watched 3 different videos. To help with the spread of the injection epoxy resin. Used a roller to help spread it.

Great video and advice. I’m thinking that using a paint roller on the outside to spread the internal adhesive might help.

No. pull everything off, scrape the Luan 1/8 ply wood off of the fiberglass carefully, then do the same with the foam insulation, then use Stabond E-183 to glue NEW LUAN 1/8 ply to the foam, then use Stabond 440C to glue the fiberglass back to the LUAN. use a Vinyl Floor Roller at each stage to press on the contact glue. Then reseal the top side and bottom. the hardest part is having someone help guide the Luan and fiberglass to match the holes. FYI oversize the luan and cut to fit but the fiberglass has to match perfect. I have done this twice, You will get a great results. NOTE: Of course fix any wood rot in the wall before putting back together.

Thanks for sharing. Delimitation can seem like a daunting task. Your video made it seem a bit less intimidating.

One tip to make this easier is to purchase empty refillable caulk tubes. They are cheaper than the syringes and easier to use in any standard caulk gun. Getting ready to tackle this repair as soon as my supplies get here from Amazon.

MVP thanks for uploading.

That really does look nice now, what a difference.

My old class c motorhome has such bad delam and rot, I'm going to have to just open the wall to do repairs. On the plus side, its corrugated, in two pieces (upper and lower) and not nearly as tall as your trailer. So it should be easier to apply the epoxy. It's on the side, not the rear, so I can just run long straps all the way around it to clamp on wood. Anyway good video. I will look for the epoxy you used when I get around to tearing into it.

Very nice video. You've inspired me to fix mine.

good job and thanks for the video. i need to do mine now.

So after 3 years how's it holding up

Awesome video!!!!!

Nice job.

Where can I buy Pro Marinel laminating Epoxy all I found was pro marine table top epoxy are they the same. your video was very helpful thanks

Could you use a inch by four in roller to apply the epoxy since there is so much space?

I've been fixing RV's I buy/sell for many years. This is the way. Epoxy EVERYTHING and use coring in pourable spaces. Use exterior walls to make jigs using 4x4, plywood sheets (for are pressure) and push together. Brace interior before of course. And Pro Marine is a great place to get material too. Great video.

Thanks alot for the video. I have a class C with serious delamination and tought about doing something like this. Because of this video I found the epoxy you used and have come up with an injection system and a clamping system that works for my situation. It is working wonderfully. There are some small areas that still have a little bubbling, but it is still 1000% better than it was. I also had to rebuild the over cab bunk area where the floor of that rotted out. in that area I used both epoxy and Liquid Nails. Many people talk about the roofs leaking, but in my case the roof is perfect. the water leaks on my RV were at the corners of the walls where Winnebago did a LOUSY job of sealing the trim pieces. I will say that in my research and experience I have found that Silicone is NOT the sealant that needs to be used in these areas. I have found that the butyl tape that the manufacturers use IS the thing to use but be careful to get full sealing on both sides of the joint. The manufacturer job only put tape up to the corner, when to seal the corner requires wrapping the tape around the joint. Anyway my suggestion to anyone doing this type repair is to work with the situation you are given. There is no " One Size Fits All". Just make sure that what you are doing makes sense, that is my barometer.

It was water that caused the problem.Impossible to dry it out. I don't know how the expoxy can work when it is wet.

Thanks for taking the time to make the video. Have a class c that had ever so slight crack in the caulk on the roof that allowed water intrusion. Sidewall bubble. Gonna try West system epoxy as soon as the weather is warm enough.

Wow, you did an awesome job, I am researching for my own RV Delamination, very nervous attempting repairs. Thanks for Sharing.👍

With there being 3 layers of separation, when you were injecting the epoxy, did you inject epoxy both sides of the middle layer. In other words between the inside of the Filon or fibreglass and the rear of the middle layer and the frontside of the middle layer and the backside of the foam layer...Hope I'm clear enough.Thanks

Excellent job, thank you Just about to start my project

I am about to buy a very small RV trailer that I may have to repair its front cap and front portions of the sides that adjoin to the front cap. The exterior skin is delaminating like this and has bubbles. I'm thinking of buying 2' by 10' corrugated metal from a hardware store and bolting them thru the front every 16" or so. Then on the seams I'm going to cover them and the bolt heads with white EDPM "eternabond" tape. Should this work well enough?

I assume you will want to dry out the area first?

What is the epoxy name? There's lots of different one's out there, I was looking at max gpe

Thanks for the video. I tried this and it worked pretty good but my mixture was pretty watery so it didn't go into the smaller edges or hard to reach places. I ended up going back with 3/4" PVC stuck on the end of a caulking gun to squirt construction adhesive into the spots I couldn't get with the epoxy.

I think there is water behind that means its rotted. What you are doing is putting the horse behind the card.

Can this be applied on exterior bunk door repair? I am wondering if it would have been a bit cleaner job if tear up the entire laminate panel sheet to expose any damaged wood.

Thanks for this

You could’ve used some adjustable shims under your clamping 2x4’s and clamped the whole back end tight at once. The way you had it clamped, all you needed to do was put a vertical strip of plywood near the corner and tap shims between the clamp strap and plywood. 3 points of pressure is better than 2, especially when the third turns two steps into one.

In order to thin out the epoxy, he used acetone. Neat

Nice job. I've got this going on on the left side of my 5th wheel. Unfortunately, it is corrugated fiberglass siding, so I'm going to have to think about how to clamp that down. Question - what were the multiple layers under the siding made of? Nothing that would develop dry rot, I assume? That was my biggest concern. But if I can do mine this way it would be a big relief, because it's a 29-foot 5th wheel and that siding goes from one end to the other without any breaks in it. It would be very unweildy to handle if I had to remove it. Side note - it's too bad that those decals on your 5th wheel are peeling so bad. I have never understood why these manufacturers use decals on these things - they all start looking bad after just a few years. Mine was bad too, so I sanded them down and spray painted over them. It looks so much better now.

Nice job. Going to attempt my old rv sometime this year.

Did you have any concern or problem with using the clamp system on the ladder? It looks like it pulls it back?

Friggin genius! thanks!

fiberglass resin stuff from the auto parts store? whats your alls take on that think it would work?

put bubble wrap on your clamping board and it will do even better..

Nope.

Nice job . I enjoyed your explanations and your willingness to tackle a really tough project.

Sexelent! Very nice. I'm looking at a motorhome that has delam under the decals-only under the decals. Wonder What would cause that? What did they Do when they put the decals on? Great video. Thanks.

Great job and showing all the tricks. Thanks for sharing.

How and whey does this happen . What do I look for so this doesn’t happy Elsewhere on my trailer

Thanks!

Nice detailed information. I have a bubble from an old roof leak. The previous owner had a new expensive roof put on and didn't care much about the delamination. Wall is totally dry and only the plastic/fiberglass sheet is separated from the wood. Thank You.

I did this repair above my slide-out using the same stuff. I injected the wall and then place wood over it and press it tight using the side of my house. 24 hours later I pulled it apart and it revealed bulges in the wall like the siding swelled from the heat of the epoxy. Where the bulges are there is not adhesion but, the rest adhered. I'm at a loss now of how to fix it because it is where the gasket goes for the slide-out. Any suggestions?

Could you use table top epoxy or does it need to be laminating epoxy?

Hey there nice repair are you able to contact me so I can get some information on the repair

What about all the rotten wood behind the delamination pannel?

Nice repair. I think it will work for awhile but the long term effects may not last for ever...

Hows it holding up? I have some minor delam I need to repair. Curious if the epoxy is safe for the styrofoam? Some melts it

can you use this in a rv floor also to make it less spongy

I gonna have to try this on my slide out. Both sides delaminated

You did not address fixing the problem that caused the water leak, that caused the rot, that caused the delamination of the fiberglass. From what you showed on the video, I know what caused it because I had this problem before and fixed it. It was the factory installation of the marker lights at the top. They are the wrong lights for a camper. Note the very large hole in the wall, under the light, for the light mount. If and when the light lens cracks or the seal fails, water goes straight through the large hole, causing your major problem. The remedy; first, fill factory large hole with fiberglass, drill new small hole just big enough for the electrical wire, pull wire through the small hole and seal with silicone, replace those lights with the ones that mount flush to the fiberglass.

What was the name of epoxy And where did you get it

Can I do the same from the inside?

That was a great job. Where did you get the epoxy?

Thanks for making this video! You inspired me into fixing mine. Question, the pro marine suppliers I’ve found on Amazon say for wood table top, is it the same one you used?

I appreciate the fact that you are trying to save money. With that said, this is not the right way to do it. The structure integrity has been compromised and you are only dealing with the cosmetics. Proper way would be to take it apart and replace the rot/damage that came with the delamination. If you invested thousands into the rig; it’s a small skip to spend a few hundred in rebuilding the wall and relaminating it. My regrets are to you for the damage. Even more so to the next owner who has no clue what he has purchased.

The biggest problem why it delaminated it's because of the wood is rotten on the inside
