For optimal results, make sure you have got a smooth and even surface before impressing with the Rolling Pins. *** We recommend using a plain Rolling Pin for this. 3rd - Depending on the type of putty/clay, it is advisable to wet the Rolling Pin to prevent any sticking. 4th - Slowly move the Rolling Pin applying equal pressure at all points for an even texture. 5th - Trim any excess putty/clay with a sharp knife. It is recommended to do this once it has dried to avoid any deformations in the putty/clay. *** For this type of epoxy putties, it is very important to clean the rolling pins properly after use.
