Well, we too are approaching the 4th coat of paint. The first 2 coats were following the instructions to a “T”. The 3 Coat was applied heavily not following the instructions.
There are still some remnants of lines and we are going to work on our 4th coat.
I am wondering if painting over a white wall is the problem here. If the wall was a darker color to begin with it might have been easier. We are using a darker green river rock.
Also, the card states 28 inches by 28 inch square, should this area be smaller?
