adhesive removal

Has anyone tried to remove the factory adhesive from the nomex gasket before installation?

AZRP

Nakedwhiz has some info on gasket removal. -RP

I have tried freezing and pulling. I have not been able to even get an edge of the adhesive to lift.

I have been wondering about getting some parchment paper and a baking pan and putting the nomex in the oven.

It appears that heat is the only weak link...

Do you already have a replacement nomex with the adhesive on it? If not, the mothership was sending out nomex gasket sans the adhesive to some people after they received so many complaints about the adhesive failing. If you get one of these, you can just adhere with the 3M Super 77 spray or high temp silicone and you'll be good to go.

If you already have one with the adhesive, you may as well bite the bullet and apply it with the factory adhesive ONLY and IF it fails, then reapply using the 77. That is what I ended up doing. Mark

Mark gave me this advice when I got my NOMEX also. And he was right on. Would prefer a one-step, but not so.

Last week, I emailed HQ to tell them about my fried gaskets on my large and medium. I've only had the eggs since June. I requested the nomex replacements, sans adhesive, and the sent them right out. I just got mine in the mail yesterday. Now I have to figure out how to fully remove what's left of the old gaskets.

Fred's Music and Barbeque just posted videos on his website on his technique of removing old gaskets. It's a two part series worth watching if you're getting ready to do it yourself. Mark

I e-mailed the Mothership asking them if I could swap my unopened Nomex gasket with adhesive for a Nomex gasket without adhesive... they said no need to send my gasket back to them. They asked me what size egg I had, and what my shipping address was... then sent me a brand new Nomex gasket without adhesive at no charge!

+1 for BGE Customer Service! :woohoo:

I was having all sorts of trouble with new gaskets staying in place until I realized that while applying I was inadvertantly stretching the gasket material a little as I applied it around the rim (yes I know the instructions even say to not do this). The last time I replaced I was very careful to not stretch the material at all while I applied it and it has since stayed in place. I did paint on some 3M 77 before putting on the new Nomex material including the factory adhesive. Hope that helps.

Mark,

Thanks for posting the link. I watched part 1 and then clicked part 2. Part 2 went on to cooking ribs. When I get a little more time I need to search out the proper part 2.

I wonder where he got the double thick felt gasket. Lately the gasket issue has been the adhesive rather than the felt material itself.

The dollar bill test looked like a terrible match, however, Fred acknowledged the same. I am guessing part 2 deals with that.

Using the acetone, scouring pad and razor blade is a lot of needless work. Using 91% alcohol seems to cut the adhesive a little faster.

Heat is much easier and much quicker. It takes about 15 minutes to get top & bottom clean.

I have also found a 'adhesive remover' that cuts through gasket & adhesive like 'butter'. However, BGE said not to use any type of chemical to remove the adhesive.

dukedog,

For what it's worth, BGE specifically says not to use power tools or sanding disks on the egg surface. I was specifically told it will void the warranty.

Good point....I edited my post to remove that method. Thanks!

Mark,


I, and, I am sure many others appreciate your sharing what you used. These experiences help us all - not criticizing at all.

I have had ton's of issues with gaskets. I ended up calling BGE and just passing on what was told to me. I was also told the surfaces on the eggs were 'trued/machined' for flatness. Waves along the surface is a problem.

I appreciate your sharing and these things helps everyone on the forum. A lot of people use power tools when removing the gasket.

Again, thanks for posting. Kent

Not sure why the part 2 after watching part 1 went to ribs, but I went back to the original link and clicked part 2 from there.

I was told by BGE that the mating surfaces are supposed to be trued/machined in manufacturing.

I had a wave on my medium and there is a small one on my large. I used a sheet of glass to check it out.

I think Fred's medium has a problem with the surface on the egg where the band sits. It looked like his band was above the ridge. Thus there was enough height on the egg for the band to rest below the ridge of the egg. One shouldn't have to sue a rubber mallet or such when installing/adjusting the bands.

Having to continually 'beat' down the band would lead me to think there was an inward taper on the surface of the egg where the band rests. I had an inward taper on my medium. The bands slowly 'crept' away from the band ridge. Eventually I would hear the metal click of the bands touching when I closed the dome. I had to get a replacement egg to resolve that problem.

Thanks GG, I'd just hate to lead anyone astray into voided warranty land, so I removed the method. Much appreciate you pointing that out for me!

Psssst. I know it's Goo Gone, but I won't tell anybody.

Grandpas Grub

:laugh: :laugh: :laugh:

Actually Goo Gone and Goo Gone Extreme didn't work all that good.

Oops! make the job easier than heat.

This process was extremely easy, however, I want this to be clear - if anyone decides to use this method BGE specifically said not to use Goo Gone or anything like Goo Gone.

Did they explain why they think acetone is ok and Oops! is not? I alway want to know why something is. I have access to trichloroethylene at work. Bet that sh*t would strip the friggin gaskets and adhesive off. :evil:

The Naked Whiz

Hey Randy! I think he is talking about removing the adhesive from the gasket before applying it using some other adhesive.

Grandpas Grub

I was told the petroleum (checmicals) would go into the ceramic and then the adhesive on the new gasket would give way.

Now with that said I used the oops on my large and my felt gasket has held well.

The gasket is now worn out and needs replacing. I am going to follow your lead when I do the next replacement.
