Bricking the Lighthouse

Today I made the brickwork pattern on my lighthouse. I did this by first carving a brickwork pattern the size I needed into carbody filler . I then made a texture mat of this carving by covering it with silicone. I then covered a section of the MDF cone shape that I lathed out in car body filler and wrapped the silicone mat around it to transfer the brick pattern. I think the result is quite effective, the end result looks like weathered rendering that has worn away in places to reveal the brick underneath it. However it was quite problematic holding the silicone mat in place, as I had to wait for the car body filler to set before I could peel it away.
