Well, afet our 4th coat, the lines are still there.
Now this time we applied the paint, we used 18 inch square. we rolled the roller in the same direction. we loaded the roller (heavy)and rolled down 18 inches and moved over starting at the top and rolled down 18 inches. reloades the paint and started down the wall. after one colum was done we (dry) roled the entire colum.
Now to make things more interesting, we had 2 rollers. while i used one the wife reloaded the other. this time the paint was still wet when we did the dry roll.
But no luck! I am into it $100 for paint and another $20 or more for the 4 rollers. we have made the decision to paint over the river rock. I will try to get some of my money back for the paint.
