GOG Glue Test Results....so far

LinLeeAugust 26, 2007

Okay then, I made a GOG test using GEII, Weldbond & MacGlue.

The test was started last Thursday and it's been raining

ever since...so needless to say a tad bit humid.

This was the setup:

Fresh GEII:

Fresh Weldbond:

Fresh MAC:

These photo's were taken mere minutes ago.

The GEII is completely dry and quite opaque compared to the MAC. The Weldbond is still not drying so it's clearness compared to the MAC is yet to be seen.
GEII:

Weldbond

MAC:

The MAC does indeed look crystal clear with exception of some minor bubbles. But turned slightly into the sun there
can still be seen a milky haze. This may go away in time...I'll let you know.

Wench said Mac was pricey, how much more pricey than Weldbond?

Okay, who here uses this stuff(mac) and how happy are you with it and does it work as good as it looks??? I'd try to order some if it's that good as the marine silicone is a bit pricier, at $4.29 for a 3oz tube. But it's the shipping and handling also so...
I wonder about that 6000 stuff, I've seen it around here, does it dry nice???
I think what I really need to do is be more careful with the actual glueing part, not be so sloppy, I just smear it on and get er done!!! Could have better looking work if I just tried to be more perfectionist! Ha! I'm supposed to be a Virgo, which supposedly means I am a perfectionist!! I am the complete opposite!!!! But I am perfectly imperfect!!!

Mosaicwench made some coasters using it - but I'll be darned if I can find that post. I use E-6000 on glass , but not on GOG stuff. I think it dries pretty cloudy - but it holds. I'm wondering if that Mac glue will hold together a totem . You can see my GE II when it dried - it's cloudy. I'd love to use something strong & clear.

More info:

I paid:
Mac - $25.50 for 2 8oz. bottles from the Mac site. ($10 per 8oz)
Weldbond - $4.99 for 8oz. @ Local store
GEII - $3.44 for 2.8oz @ Local Big Box Store

GEII Pro's: The silicone has leveling ability
Easy to use
Holds very well and fairly quickly to vertical surfaces
Easy to remove already stuck pieces
Easy cleanup with a blade
Can be used for outdoor pieces
Can be purchased locally
You feel really good after about an hour in a closed room

GEII Con's: Fairly pricey because of the amount you use
Does not dry crystal clear
Tends to change color after awhile
You need denatured alcohol to really clean off residue
Possible loss of brain cells in an inclosed room

Weldbond Pro's: Not too pricey
No real learning curve as it applies just like Elmer's,
Cleans up with water
Very good hold

Weldbond Con's: Not as easy to find locally
Shouldn't be used for outdoor projects
No immediate vertical hold
Drying can take a very long time

Mac Pro's: Dry/hold time is fairly quick tho not as fast as GEII
Strong hold
Clear on application
Edges cleaned up well with exacto knife
At this point it looks to be the clearest
(Jury's still out on this)
Cost effective as very little adhesive is used as it is just a tad thicker than water

Mac Con's: Internet sales only at this time Email from owner said that they are working on retail store sales
No immediate vertical hold
Indoor pieces only

After the Welbond finally dries I will do a bleed test.

I didn't see this until after I posted...Yes the Mac
can be considered pricey, however if it does turn out to be the best GOG adhesive the price would be inconsequential as you use so very little of it compared to the quantities used of GEII.

Oz per oz...
GEII ends up being $1.23 per oz.
Mac ends up being $1.25 per oz.
You will use more GEII on 1 piece of glass than you will
Mac. So the Mac, if you so choose, is actually a more cost effective product.

Here's a CON of Mac not listed. Once it's dry, it's almost impossible to get off - of ANYTHING. It's not like Weldbond where it can be re-wetted and removed, or in some cases just scraped off. It's ON - for good.

If you're a tidy mosaicer, not a problem. If you're like me and have glue all over, its a BIG con. I made some coasters with scraps and Mac glue and I'm impressed by the clarity (before grouting - I haven't gotten there yet).

I don't know that I would use it on my glass-on-glass windows, though. Even with it's superior clarity the "not being able to rub it off" is a drawback for me. I tend to squirt glue into an area on which I'm working and then place the glass. If I don't or can't place all the glass before the glue dries, I want to be able to easily remove the dried glue and begin again where I left off. Not being able to do that makes MAC iffy for me in a GOG circumstance.

And on a side note, am I the ONLY one here who cannot smell the silicone? I find it has NO fumes. . . or does that mean I'm now so overwhelmed by them that my brain no longer registers smelling them??

And I sent the above before mentioning one more thing . . .

There is talk (somehwere on the internet and I cant recall where) about using alcohol to speed the drying time of Weldbond.

The theory is that you glue down some glass (or whatever), dribble in a little alcohol (rubbing, not sipping) between the pieces, wait a few minutes and soak up what remains.

Darn, I wish I could remember where I read the instructions for this process.

Hmmm . . maybe the silcone IS really getting to me . . .

( ........ even if the seal is waterproof - would condensation still take place ??? ) Decisions,decisions ~~~

It's water-based cleanup so I wouldn't use it outdoors. Indoor totems?

Make a small test totem and set it outside for us to watch. Too bad you didn't do it last week - we could have watched it float away in the rains!

That makes sense - Weldbond takes air to dry it . Alcohol will evaporate it sooner . I made a couple GOG that I did with Weldbond -- I had BIG pieces with glue on the back -- that was 6 months ago - I don't think it is still dry :(

If there's a test on this stuff that I'm missing let me know...sure I can't possibly think of everything.

After the Weldbond dries there will be a bleed test with colored water I'm thinking...not soaked in it, but just enough to see what edges didn't attach well.

After that I'll have it soak in water to see when some of the glue fails.
Already know for a fact that it doesn't take much time
in a waterbath for Weldbond to release. I had stuck some tiles to glass that I changed my mind about a couple months later, thoroughly dried, and they slid off in no time at all.

I too will be curious about the Mac as the website does indeed
say "weather-resistant" but not "proof". Once grouted and sealed it may take a long time soaking to release.

I don't have any personal glue alliance...just would love to find a product for GOG I can stick with (pun intended :0)

I was just re-reading the Mac site which states that
the glue is "water resistant"...which usually means
that it will eventually break down if wet.

However the bottle itself clearly states "waterporoof"

The site also says that Mac is a marine adhesive and can be used to bond carpets in boats.

Hope I'm not boring everyone to death ;o)

Linlee, thanks for taking on this challenge and sharing it with us. This is great info for al of us.

I believe I've read for Weldbond, the glue should only be put on the outer edges of the glass and void in the center. Thie permits it to dry easier.

ba1je, I still use Weldbond on my terra cotta trays, after I grout I seal them with a concrete sealer and have not had a problem yet and I've made several of them! I have one outside for 2 years AND I live in florida too.

MW, I don't always smell GE II but I do get headaches when I've bent over and used it for hours. I usually use GEII for repairs when I'm grouting. I haven't used it for glueing a big project in quite a while now.

Calam, I use E6000 for some things such as when I'm in a rush and don't want to wait for Weldbond to dry or for repairs. I almost exclusivley use E6000 when I glue on glass nuggets because it holds the weight better than Weldbond. I don't have a problem with it clouding or leaving bubbles but have not done a GOG test.

I'm curious about how Lexel and E6000 would test on GOG.

seaglassic

now I'm double curious..
and I'm going to ask my son, who does fiberglass repairs on boats.
it seems logical, that there would be an adhesive that should be available, that is used for marine repairs, available in smaller quantities.
but I know..the snag would be if it's clear or not.

I think I asked him something to this effect once before but I can't remember what he and I talked about.
then again, for some projects, it wouldn't matter.

For the record, Weldbond's own paperwork claims it to be an outdoor adhesive.

And I'm with wench, I don't smell GEII either and no one in my house complains of it.

Here's my last update on the mini glue experiment.
I'll leave the 527, Lexel (?) glue test to the next
person.

After the glues finally dried, actually 1 glue, the Weldbond took forever. I plunged the test into water for a total of 3 days.

The SiliconeII looked the same coming out as it did going in...kinda murky with bubbles. Of course it was still as removable as always using a blade. Also note that this is the only one of the three that can be used for leveling.

The Weldbond pretty much slid off of the glass at about 3 hours into the water bath. But note that when it actually dried it was very clear.

The Mac dried fast and clear. That milky haze eventually went away. At the 3 hour mark the edges of the glue that were squished out of the test piece did start to get a milky edge. At this point it was really easy to pull this overflow off with my finger nail. But even after the 3 day mark I couldn't pry that thing off without fear of shattering the test plate.

I'm kinda sold on the Mac so far...

The Weldbond website recommends these instructions for doing a GOG.
Maybe that's why it took so long to dry?

I have changed my tune about Mac glue. I really really really like it. Outstanding clarity. And I got two bottles for Christmas!

I used it for part of my last window and am using it exclusively on my current gog window. I've "cleaned up" my application techniques a bit and that seems to help. I've also discovered that acetone is Mac solvent. So when I need to clean up I can pull out the nail polish remover (and aren't those fumes fun? Wheeeee!)

Thanks for reviving this thread.

I too am looking for the perfect GOG glue, especially for large pieces of glass. I'm experimenting with mod podge. It brushes on like elmers, runs about $1 for 2oz, and it holds tight. One piece has matt and the other is gloss. Matt is still hazy after a week. The gloss dried clear immediately. I'll soak it in water this morning and let you know how it does. For those of you that use GEII, how long did it take for a color change? I've been using '100% silicone', it's cheaper and the salesman said it was the same. It dries crystal clear. And I don't find as many air bubbles in it as what I see in this experiment. When I press the glass together, I rock it, allowing the air to go out the side. I'm wondering if there is a difference in the product or the technique? Any ideas?

That 100% silicone phrase still has me baffled. Looking at the shelves in HD, ALL of the tubes are labeled 100% silicone...so WHAT is the difference between the products? Granted I have lost a few of my math skills over the years, but if something is 100% xyz, there isn't any numerical or physical room for anything else. So-o-o-o back to the question - why is some 100% silicone suitable for aquariums, other 100% suitable for windows and doors, others for bathrooms and kitchens, etc.

Good info on that modge-podge gloss. I probably will still go with the MAC for my bathroom project (with all that steam & stuff), but this is good to know for other less-humid applications.

I certainly wouldn't try anything new (glue)on a bathroom project! You want to do it only once, and have it stay. I'm confused on the silicone also. Is EGII 100% silicone? Maybe it's all interchangable, and they package it to appear that we need to purchase different products for different applications - more $$$$?

I have heard bad things about Mac and humidity. I remember reading (on another mosaic forum upon which I lurk) that someone used Mac in a humid environment and it never cured. Perhaps if you work outside the bath and when fully dry install whatever it is you're going to do, it would work better? It IS after all, still a water based adhesive until fully cured.

d3bbi is correct. When gluing glass to glass with Weldbond you should put it on the outside edges only, leaving a small air pocket in the middle. The air pocket helps the water evaporate which is how the glue dries. Weldbond can most definitely be used for outside projects. I've used it on garden tables and birdbaths with great success for many years.
