THIS IS A PATTERN ROLLER- Which means you roll it over something (like concrete) and get a reverse pattern. What you see on the roller, is the pattern you will see on your finished surface IF YOU DO IT RIGHT. If you don't d it right, you won't get that look. Too wet of concrete, won't work well. Too dry of concrete, won't work well. You also need to use a release so the roller doesn't stick- release is made for concrete. DO NOT USE DIESEL FUEL! Slate Stamp pattern roller for curbing, concrete borders, steps, and more. Very hard and durable rollers for years of service. The super hard material we make our rollers from makes stamping the pattern into concrete easier, even on harder concrete and curbing. 11 different Rollers are available Individually or as a 11 Pack Set. Use multiple different Rollers over each other to create custom looks. Create more variations with your own grout lines using a chisel or concrete trowel to make the lines, for many brick and stone variations.

HOW TO USE: Typically used to roll a stamp pattern into fresh concrete or curbing. Place concrete or curbing as normal. Apply a release agent, such as Colored Powder Release to creating a two-tone look to the concrete/curbing, and then roll the stamp roller over the concrete/curbing. Allow a few days to dry before washing off the release, and sealing the concrete/curbing if desired. Clean roller with water and a brush immediately after use to avoid cement buildup.
