How do I fix Acrylic?

[vincejo28]

I am sure this question has been asked before; but here I go"¦"¦.

I have an acrylic sump that was given to me. One side of the sump has been cracked and siliconed together. It currently holds water; however I don't really trust it. I am going to remove the silicone and would like to correctly glue the acrylic together.

What would I use to re-glue the acrylic?
I also have a chip in one of the corners"¦it does not cause the tank to leak"¦but I want to strengthen it so that it does not cause future problems.

What would I use to fix the chip?

What glue would I use to glue acrylic baffles in?

Thanks in advance!

Once you get it nice and clean.."denature alcohol" glue some patches over the problem area preferably 1/4" thick...use weld on 3 or 4 and follow up with 16 like silicone with a bead around it...like mentioned pics would help...also if there is a crack drill a hole in to stop the crack from spreading....

Sorry! It was difficult to go out in the freezing cold garage!!!! We have had 3 days of no school due to snow. I am going to try to post these pics.

This is the corner that may leak

It is difficult to see....but it is cracked toward the bottom.

Not sure why the other pic won't work?

I had an overflow that broke in shipment, after cleaning it up I used some weld-on acrylic glue to put it back together. It held up perfect. Solid as it was new.

I had a similar issue when I purchase our 150. The overflow was cracked down both sides along the seam. This is how I repaired it.

I would clean the silicone off. Cut a piece of ½ square acrylic rod to fit. After cutting the square rod, do a practice run. If all is well run a bead of Weld-On 16 down the inside of the box and glue the rod in place. Hold pressure for a couple of minutes to set the glue. After this dries run a bead down both sides of the rod and top end of the rod to insure a good water tight seal. I would let it completely dry for a couple of days then do a leak test.

I have some pics if you would like to see the finished repair.
