For BIAB is there a particular size of paint strainer to use or are they all the same size? Also, do they have a tendenancy to tear when you lift it out of the wort or are they pretty durable?

AFAIK, paint strainer bags only come in cardboard cones for 1 gallon, 1 gallon bags and 5 gallon bags. The 5 gallon ones are what most people use for BIAB.

I have done 3 BIAB with the 5 gallon bag. There is no sign that there is any weakening. I am not afraid that it will tear or split open.

I used a 5 gallon strainer on a 10qt pot for a 1 gallon batch and it worked great. I think they're pretty durable but I guess that depends on the amount of grains you're using. One thing i'm not sure if I need to worry about is if it will burn from touching the bottom of the pot.

Not trying to pee in anyone's Cheerios.. but paint strainer bags aren't even close to being food-grade. I'd shop around for a food-grade grain bag. I don't know if I'm allowed to link items here, so I won't. But there are food-grade grain bags sold by many reputable beer supply websites.

Used paint strainer bags for biab for years. They work fine. And yes, if they get scorched, they're Swiss cheese. Don't ask how I know.

C'mon man, most BIAB's are paint strainer bags, or voile curtain cloth from Walmart. Think curtains are "food grade"?

The 5 gal bag is a little small in a 10 gal pot. It will work, and I've used one many times, but make sure you have some kind of clips to help hold it to the rim of the pot. I Have one that's on it's 10th batch with no signs of weakening. I'm getting(or making) a bigger one so the grain isn't as compressed in the bag when making bigger beers with a 13Lb + grain bill.

I picked up two 5 gallon paint strainer bags from Lowe's for around $3, anyone have any idea how much gain they can handle? I'm thinking of brewing Edworts Robust Porter which is at just about 14 lbs.

Long term I would go with voile material or a curtain, not even sowing it, just clipping to my 9 gallon Bayou Classic.

Course not. That's one of the many reasons I don't BIAB : P
