After reading all these horrible things about river rock paint, I called customer service (1.800.379.7656) There I recieved wondefull assistance on applying the ralph lauren paint. She did tell me that the darker the color, the harder it is to apply. Because of this I needed to add 3/4c of Flotral to the paint which is made by the Flood Company. Also she did recommend to forego the special rollers and use a 3/8" knapp roller and ot let it soak in the paint before using it. The River Rock Paint is made to go on heavy and thick. In the end, I did not use the paint because I needed it to paint a mural. Customer Service advised me to return the paint because it definately is not made to be used with a brush! For all of you out there! Call them before you begin your Ralph Lauren adventure!
