Chad and Belinda Posted May 14, 2012 Share Posted May 14, 2012 I am needing to repair a small crack on our acrylic sump. It is in the upper corner of my sump and only leaks on occassion. I would like to know what works best when repairing acrylic? Let me know...I hope to get this done in the next day or so. Thanks. Quote Link to comment Share on other sites More sharing options...
Sherita Posted May 14, 2012 Share Posted May 14, 2012 Belinda, normally a bead of Weld-On #16 applied to a crack will fix it. Even better, if you can get a small patch of acrylic and use the #16 to glue it in place, that will strengthen it even more. Gimme a call if you need help/advice, ya know my number Quote Link to comment Share on other sites More sharing options...
+olaggie01 Posted May 14, 2012 Share Posted May 14, 2012 Hi Chad/Belinda. I have some weldon 4, which is similar to the 18, but a little runnier. I have some if you would like to use it. I also have some clear acrylic that might work as a patch. If you guys are around today, I could come over, fix the sump and pick up some of the LR.

(Bio)³ Posted May 14, 2012 Share Posted May 14, 2012 For leaks/cracks I use weldon 4 because it flows similar to water. If you suck some up in a syringe and put it onto the crack it will get sucked in and fused the area together again, if it is a larger gap type crack then you will need to switch to the weldon 16 to fill bigger gaps.
