Then I dry the whole thing, using a hairdryer on a medium heat setting. To remove any excess, take a piece of sandpaper and swipe downwards over the overhang, and it will come off quickly. When dry, using a sponge, I apply another very thin layer of Finishing Coat or Tuff Top Coat and dry it again.
At this stage, take a 120-grit sanding sponge and sand it all over. This will not remove the image as the sealant has protected it but it will flatten the surface even more. You can repeat this step as many times as you need to, but usually once or twice will do it. Finally, one last thin coat of sealant and it will last for years.
To add an extra dimension, why not use Easy Crackle? Pictured below, I used the off-black shade Panther then Easy Crackle, and then the subtle, off-white shade Virgin to create the crackle effect. Then I used the découpage steps above, all over, to turn an old tile into a fabulous coaster. Happy découpaging!
