Sump Glue??

fsu1dolfan · Aug 5, 2009

So i have an all acrylic sump with baffles that i just bought from someone that i want to touch up....it seems that there are a couple of small leaks between the baffles and i want to touch it up with glue or a type of silicone that is reef safe....i have read alot about weldon being the best for acrylic to acrylic...what do you guys think or suggest?? I read #4 is very thin and drys very fast...i would like something thicker like silicone that i could put a thick bead over the existing glue but not sure what to use??

Thanks for the help!

You should use the thicker version of weldon... #4 is the really runny stuff and really isn't suited for this application, weldon #16 is perfect!

Thanks!!

I guess i tougher question is what local stores carry it? LOL no Home Depot, Lowes, 2 local hardware stores, Walmart, Target...None!! Sucks...looks like online might be the only way....

+1 on the #16 , the 4 is used during construction to hold things together before the 16 is applyed.

I'm pretty sure #16 is HAZMAT, I know that #4 is... in other words you have to order it online.

GL!

Ebay...just ordered both the #4 and#16 a couple weeks ago.

I was told to gap fill with acrylic that you should use something called e6600.

I've used #16 to reattach euro-bracing, fill gaps, fix CaRx with cracks (and literally small holes), etc.

Stuff works like a champ - think of it as liquid acrylic.

if you have a gap the 16 wont fill you can make fine scrapeings or cut with table saw to make saw dust from a scrap piece mix with 16 to make it thick enough to fill it

yeah... problem i've found carrying the stuff is shipping is enormously high... it was like 16 bucks for me to ship some #16, and i just got a large tube.

Ok so i found this
DAP 00688 SILICONE AQUARIUM SEALANT 2.8 Oz

It's not weld-on but i can get it right away since i want to work on my sump this weekend....DAP Aqaurium Silicone...would this work for the acrylic sump?

i'm trying to avoid online and waiting for shipping!

Use this stuff. We had a speaker (builds acrylic tanks) at a club meeting that said to use this glue to gap fill acrylic.

E6000 Glue : Artbeads.com
