Ok this is the situation... First I created a foux marble finish on the Allumalite. Then I cut primed and painted my hdu elements leaving the back side of the HDU bare. I want to apply using lexan (I think that is how you spell it). And have read the back posts that it can be used. What I would like to ask is what is the method? Should it be clamped like Gorrilla glue? All my paints are one shot.... do I need to sand the allumalite where the hdu elements will be fassened? And anyother tips and warnings would be great. Thanks!!
And yes I became a resident because I think this site is great!!

i think you mean epoxy to attach your hdu to alumalite. i've used both silicone and epoxy to attach hdu to dibond(alum finish product)...also some vhb tape inbetween the set up time. hopefully it can be laid flat while you attach...otherwise you will definitely want to use the vhb tape too. and yes you should sand lightly where you are attaching...raw material to raw material.

Shane,
The adhesive you are referring to is Lexel. Lexan is a high impact polycarbonate plastic sheet.
As Karyn mentioned, light sanding will help the bond.

Sorry about the miss spell I'm not good at that... when I got a D in spelling my mom wanted to know if I had spelled my name right. heehe Ok so I sand the allumalite and then lay on the lexel click my heals twice and spin in a circle 3 or 4 times anything else I should know..

If you're spinning and clicking your heels, turn on the fan, you're probably slowly suffocating.
On the inside you're spinning and clicking-on the outside you've smacked your head and are laying on the floor twitching.

Is Lexal the best choice for hdu to painted metal (sanded of course)?
sorry to add a question to a question.
Posted by Shane Bennett (Member # 3968) on :
John, good question... I was going to use the Lexal because that is what I had on hand.. this sign is for me by the way. In some ways that makes it easier and other ways it makes it harder. So How about it you profestional sign folks... does Lexal realy work that good or is it better to use something else??? Help because my hand is just itching to hang this thing.... :}

Sorry I didn't contribute in my earlier post just being dumb. I would scuff the alumalite and use PB-240. Clamp it. I've never used Lexel, so can't tell you anything there.

I use Lexel alot but mainly for installing dimensional letter with posting. It eventually sticks to anything, but it takes awhile to dry. It's always nice to do a clipped off screw or posthole to keep it from sliding. I was told once that these silicon procucts never really dry in places. It stays maybe too flexible. You can use regular silicon and use it as contact cement. Flash it briefly and just press them together. I've been using more PL2000 urethane construction cement lately. It's like top of the line liquid nails. It also drys a little slow but I'd trust it on the bare hdo and the alumalite and this stuff gets really rigid

I use epoxy almost exclusivly to attach HDU to almost anything. If it's an HDU carved piece that I'm adding, I lay the sheet flat, put a bead of epoxy around the perimeter about a half inch in from the edge, set in place, then I lay a bag of smaltz (some sand in a plastic bag will work) on top until the HDU sets. I've always been afraid of using urethane glues like Gorilla Glue or PB 240 because of their tendancy to expand. Scuff the Alumalite.
