Will never buy this paint again, bought it because of review on Consumers Report, boy were they way off! I usually don't leave reviews, but this stuff was so bad I had too. So far we have painted a small bathroom and one wall on a bedroom wall and have had to use 2 coats to cover a previous light color paint. We were suppose to get coverage for all we had to do, we will need another 2 gals. at this rate!!!! DON"T BUY! ...and yes we washed the walls first, with TSP to make sure everything would be perfect. And we did make sure we were painting over Latex, not oil based.
