      We appreciate your interest, Steve! Rust-Oleum RockSolid Composite Deck Refresh is suitable for use on composite decking only and will not properly perform on wood surfaces.

          will this hide sap and prevent the sap from sticking

          Answer This Question

          Steven, we are happy to clarify! Rust-Oleum RockSolid Composite Deck Coat is not an opaque coating and is not intended to cover stains. This product is a toner that will refresh faded colors. Additionally, it will not prevent stains from occurring on the composite deck. - Rust-Oleum Product Support 10

                  This product was Terrific! I read all the reviews and I decided to go with the brown color. I applied it with a 3 inch brush because we have a concrete deck under our top deck and I didn’t want it to drip. It did look an orange color as people had wrote on their reviews but once I was finished it looked Amazing! We did our trex deck in 2017 and I couldn’t believe how dull it had gotten from the sun! I did apply 2 coats on our 12x40 deck and I had a little over a 1/4 of the restorer left so it went a long way! We had our sons wedding rehearsal dinner the following weekend and we received so many complements on it! I highly recommend this produce to anyone who wants to restore their trex deck to look new again!

                  The product was easy to apply to a clean surface, out of the sunlight. Apply thick coats as the product is very watery. Cleans up with soap and water. I gallon will do a 300 sq ft deck and steps. It brightened up the area and covered stains and scratches.

                  After years of trying to find a product to make my Trex deck look decent, this worked. I originally purchased brown which was really orange. I called Rust-Oleum to see if the product could be tinted. They said no. I gave my opinion on their “brown.” Since there were only four color choices available (I also expressed my opinion on that) I chose gray. We applied two coats to Woodland brown Trex and the deck finally (it’s only four years old) looks good.

                  Terrible product
                  I spent more time cursing this product than applying it. It is so thin that it splatters everywhere. First coat with a stain pad, next with a roller. Both coats it cannot be applied evenly. I'm going to end up replacing the stain with either paint or the actual boards themselves. I would give this product a 0 if I could.

                  Oh no, not something we like to hear, Tony. RockSolid Composite Deck Refresh is designed for application to properly prepped wood capped composite wood decks. Prior to application, a splash text must be conducted to confirm water absorption before applying this product. Give us a call at 800-373-6333 so we can hear more about your application and try to make things right.

                    Had an old trex deck surface that was deteriorated significantly, we wanted to refresh the look without having to replace all the deck boards. This product went on very thin but absorbed into the decking, it ultimately took about three to four coats but the deck looks like new. Very satisfied with the product so far, we'll see how it holds up over the winter.

                    Product was Horrible
                    I read all the reviews and wanted this to work. Followed all the instructions. Was even willing to deal with a brownish color even though it was supposed to be grey. Product goes on like water. Applied with a Behr stain sponge. Product soaked up into the deck. I went through 8 cans. Only been 3 months since application and color is blotchy and faded. See pics. I plan to call the customer service number in the other reviews. I would avoid this product.
