can I stretch coverage with water?
I painted a bathroom last night using 1 1/2 quarts. I mixed 1 quart of 1 color and 1/2 quart of another color. I have a little (1/2 or 3/4 cup or so) left over.
So this morning I am disappointed that the color is not quite right (despite sampling ad nauseum). I want to redo my formula using only 1/4 quart of the add-in color.
So I am afraid it is too close for comfort quantity-wise if I only buy a quart of the first color. Can I stretch with water? How much?
The paint is BM Regal eggshell.
I am also wondering if the paint roller choice makes a difference in stretch-ability. I primed using one of those skinny 6-7" rollers and I think I used less than a quart of primer (it was tinted it with a pint of leftover sample blue paint). But I painted with a standard 3/8" roller and I wonder if there is some waste in the nap of the roller. I can use the skinny roller again if that will help me get more coverage with slightly less paint.
