unless youve got a leak in an acrylic tank and need to patch it in witch case you could also use some acrylic shavings and weldon 4 to make a past' date=' its very messy to use to build with and will be betteroff using #4 and #16 whare needed.[/quote']

 

 

From what I have read, the 40 is the one to use to bond acrilic to glass. I am starting work, (or will be) on a 75 gal glass tank, into a sump, with waer flow and pressure, I don't want to do it twice, so I hope the stuff is the right stuff

Well I guess everyone has a opinion. But I think he recommends the Bostik stuff for acrylic to glass and the 40 for pvc. Maybe im reading it wrong. Are you just putting baffles in? Later Ryan

 

 

Nice call!!! I read the rong dam thing, OK looking for Bostik thenDOH!

Is this for acrylic baffles in a glass sump Blaine?? Regular silicone will work fine.

 

To be sure, it wont actually bond the surfaces....but you run a bead along both sides and underneath the baffle(on both sides)..........the silicone does bond to the glass of course and it creates little walls that hold the baffle in place, done right there is minimal to zero leakage around the baffle...and if so......surely not enough to matter if it IS just for baffles

 

Just a simple idea for ya
