How to replace carpet?

[AlexLev]

The carpet on the right side got unglued and the foam backing beneath deteriorated quite a bit. I am thinking of pulling both left & right carpets and replacing them with an SCS-interior carpet. Or should I just find a carpet store and have them custom cut something vs using SCS-Interior pre-cut? As long as the carpets have burn certificates, it's fine, right?

Few q's:

1) For those that have done this, what are some good supplies to use to clean up all the crap once the carpets are out? The spar is out in the back so I want to make sure I'm extra careful and clean it without promoting any corrosion.

2) Should I go with the ensolate foam backing again or will it just cause more problems down the road? Does it add extra protection?

3) Any other tips + tricks appreciated.

Use denatured alcohol, xylene or MEK to remove the glue. Then put in either new carpet or your carpet with the foam removed and install snaps in the floor. The female in the carpet. Two at the rear of each carpet strip. One each between the  rude pedals. Two at the forward end of the center strip. And 4 under the front of the pass seat. 2 under the front of the pilot seat.  Sailrite has The snaps and the tool

Yep, that's how I did it.... Dampen a cloth shop towel with you favorite solvent, lay it over an area you want clean (8"x8" works good) to allow it to soften up the glue.... Kinda a slow process, so plan on a 4~5 hrs depending on how old and how much glue was used

Having a few expletives at the ready would be good.

Not really needed until hour 2, plenty of time to gather them

Plastic scraper(s) and, it goes without saying, well fitting respirator. Also good if you can set up a fan to blow air into the plane (so no fumes go through it) while working in it. In the door and out the baggage door is what I did.

Actually paint stripper works very well also. Brush it on, cover with plastic from wallyworld bags and let it work Use a car body plastic bondo spreader to scrape it off Paper towels for the remainder. Clean up with rags and water. Gloves and eye protection are mandatory. So is a fan. Better than smelling MEK for hours, Works pretty fast, Same goes for the door and baggage door seals. Drape plastic to protect the paint, go slow 8" at a time and clean it up real clean.

I’m going to have to do this this winter. Anyone tried 3M General Purpose Adhesive Remover?

Skip

If you cover any of that stripper or solvent with Saran Wrap then let it set an hour it does wonders, along with the rest of Cliffy’s technique. 
 

I stripped the forward half of my wing with acetone and Saran Wrap.

Yes, works fast.

I have, didn't work all that great so went back to acetone 

[AlexLev]

Any considerations for using all these chemicals around the wing spar back there??

Dont use this stuff, it causes Hydrogen Embrittlement

go figure, right? I called them 4 or 5 years ago to ask why you cant use aircraft paint remover on aircraft, and all he said was two words, Hydrogen Embrittlement, I thanked him for his time and that was the end of our conversation 

[carusoam]

So...

Looking up Hydrogen embrittlement... because I have heard of this in my school days... mostly related to steel processing...

https://en.m.wikipedia.org/wiki/Hydrogen_embrittlement

Makes you appreciate the labeling regulations we have in the US.

Best regards,

"Hydrogen embrittles a variety of substances including steel,^[11][12][13] aluminium (at high temperatures only^[14]), and titanium.^[15] Austempered iron is also susceptible, though austempered steel (and possibly other austempered metals) display increased resistance to hydrogen embrittlement.^[16]

In tensile tests carried out on several structural metals under high-pressure molecular hydrogen environment, it has been shown that austenitic stainless steels, aluminium (including alloys), copper (including alloys, e.g. beryllium copper) are not susceptible to hydrogen embrittlement along with a few other metals.^[17][18]"

 

^{In the current use on the floor boards that are not structural in any way embrittlment really may not be an issue, Just don't get sloppy and run it on the spar to be real safe. Likewise, it seems that aluminum is only susceptible at elevated temperatures.} 

^{HE on steel, especially 4130 aircraft steel, is a big factor when that steel is chrome plated and that is why steel needs to be baked after plating to remove the hydrogen from stressed steel parts.}

I read somewhere that the auto parts store stripper failed with regard to overlapping parts and corrosion.  At least keep it off the seams

Hydrogen Embrittlement 

 

Ok. So here is a new one for me. I guess I can figure it out in context, but I’m still going to look it up.

 

 

[cliffy]

I'm not a metallurgist but here's a report . If anyone here can figure it out go for it!

Go to section 1211 (at the bottom of each page) for 4130 aircraft steel

I seem to remember that the US Air Force was using Simple Green years ago as a cleaner and it was causing HE, now Simple Green has an Aircraft formula

[jetdriven]

The green version corrodes aluminum.  The purple version kills the paint. 

[PT20J]

 I think Formula 409 also says not to use on aluminum -- at least is used to.

for 99% of my cleaning I use water and elbow grease, if it tougher a little WD-40 works well as a solvent ( @Piloto would be proud)

Mr Carter, is that a dispersing agent, or a displacement type you are describing?  @carusoam
