I do this for a living and I feel this company needs to follow through with product knowledge and research. First of all they did not invent these products, which is why thier instructions suck. Some secretarial type fom RL surely edited and proofed the text. He or she never used the product and there little changes wee a mistake. I think the best products to buy are products that have thourough booklet instructions with pictures. Chances are the person who wrote it actually used the product, not just choosing what font the instructions are written in. When will the big money guys ever learn that they just can't stick thier name on any product because the profit looked good and it was trendy. This product is best used at 60 to 70 degrees. You absolutely need to use a really good quality glossy paiint for the base coat of color. Top coat paint must be a thin flat finish paint. Timing is everything here. follow instructions to the tee. You can not go over an area that you have already done top coat on one strock one way . If you go back into your work you will be sorry because the effect will be totally diffrent from all other strokes. I found the roller did work well on large walls, but becareful not to overlap. If you goof up do not touch it or try to fix it. wait 24 hours and go back from step one or scrape off fallen sluge and smooth with sand paper. Then start with base and repeat steps. I have used this product out side and found that for exterior use you must varnish or finish with clear coat to protect. Hope this helps someone . I did not find this site until today. Suede effects are best done with thicker paint in the pattern suggested. I want to use the river rock but I want to know more about it first.
