We were ready to eat the money we'd spent on "stormy peak" RR paint and go to a flat color after reading all the negative comments. But we followed some tips from this site and used our 1 experience from a RL faux finish paint to get a beautiful river rock finish. Here's how to do it: 1. Add 3/4 cup Floetrol paint conditioner (at Home Depot) to 1 gallon River Rock paint 2. Prime walls with 2 coats of primer (Glidden Aquacrylic Gripper at Home Depot). 3. Use the RL rollers (we used a fresh roller for the 2nd coat) 4. Don't bother with the 18" squares. Instead work in 10 inch columns, working the roller lightly over the accumulated rock where columns join up until it dissapates (we'd go over it 6-9 times). Note: our first column at the corner of the wall was using the 4" corner roller. We then switched for our next column to the 9" roller and blended the lines together. We had 1 person roll the paint and the other acted as a "spotter", pointing out lines that looked unsightly. To fix these, lightly press the roller onto the wall and rework the roller over the spot till the line disappears. Do the same on the 2nd coat and it looks fantastic!
Keys to success: a)buy a piece of wood to practice this technique before going to your wall. b)Don't let too much paint accumulate on the ends of the roller when rolling in the paint tray. c) Start at the least visible wall first. We found our technique got better & better as we moved across the wall. d)Work fast. You have a couple of minutes to work the rock lines away before it starts to harden. e) overlap columns as little as possible. If you do this right, the 1st coat will look like an elegant faux finish. The second coat gives you the look of the swatch.
