When some windows were replaced a few years ago, they used brown silicon around the frames, however the edges of the silicon are trimmed off (on the brick and frame there is a definate edge to the silcon) how do you get this effect ?
Would I put some masking tape on the frame and brick then use a gun to apply the silicon and after a few minutes - after letting the silicon partly dry, run a knife through the silicom and pull the tape off ?
Any ideas really.
