I have a crack on my eshopes sump that looks as though it can run all the way to the bottom. Could weld on stop this?

I believe you can weld a acrylic sheet over the crack. And if you drill a hole at the ends of the crack it will prevent the crack from getting bigger .

stop drill the crack like Sharkboy said. Then make a sandwich with two pieces of acrylic and use weldon 16 to glue them. Use two pieces of plywood and clamp them over the sandwich to secure the patch.

I was thinking that drilling a hole would stop the crack but had not thought about an acrylic sheet. That is a good idea for sure. I am not very handy an I am sure doing that is beyond my capabilities. What size sheet and what type of weld-on should be used?

How thick of a sheet should be used on both sides?

Weld-on 16 is the thick gel weld on. I would try 1/4" minimum. It can be clear or colored, doesn't matter. you just want a good seal on your patch. Don't be afraid of using too much, you want it to seal good.

What number is the runny stuff? I was think that I would use that on the crack before I tried to drill the crack. I am afraid that I may make the crack longer as I put pressure on it to drill it.

Ive drilled acrylic before and it's pretty easy I don't think you should have to worry about that.

Just don't push hard when you drill. Let the drill bit do the work. Weld on 3 or 4 is the liquid stuff.

Also use a brad nail don't use a drill bit. The bit will pull in and if you aren't expecting it, you will crack it more. Like Murf said don't put pressure just let the weight of it do the work. Also like Murf said get acrylic for the inside and outside of the crack. Weldon 16 is pretty aggressive so will help pull the crack together just clamp the sandwich to really make it grip. 48 hours is best to let it sit clamped. Read up on the strength per 24hr period and see what you feel comfortable with.
