Question Diluted Primer

A "helpful friend" added two pints of water to two gallons of Glidden "Gripper" white exterior/interior primer-sealer in a seperate spray hopper. The instructions state: DO NOT THIN.
I did not use this watered down paint, but put back what I could into the 1 Gal paint cans. I now have two full gallon cans.
Since the ingredients state that 30-40 % by weight is water, and since over time (how much?), the paint will settle, with the water at the bottom of the can, is there a way to remove this extra water and make the paint usable, or should I just write off the $40.

Use it. It's going to be fine. If you were using it to cover water stains or something, it may affect it, but otherwise its ok.

1 pt per gallon is fine. In the summer, it may be necessary to add water just to keep product from drying out during use.

As far as settling, don't hold your breath. The solids will sink, but all the emulsifiers, binders, and glycols will float to the top. Mixed in with those is the water. Its not like its going to be able to be skimmed off.

However, for your mental "anguish" perhaps add a pint or 2 of water to your friends fuel tank. Suggest you did it to "help".

I agree it should be ok. You didn't say what you were priming - it might be a little prone to run.... just be aware of the possiblity so you can correct if needed.

I just want to make a clarification here - this is primer, not paint.

Gripper is a primer

It's not great that it's thinned...but I wouldn't throw it out
It should be OK for regular use
