West System describes applying the barrier coat using a roller, then tipping off with a piece of cut up roller to smooth out the application. Would this method work just as well with Interlux, Pettit, or whatever product I use? Or even tipping off with a brush to avoid the orange peel?
Such as described here: Barrier Coating
The hotter the day and the hotter the hull, the less chance of 'flow out' when dragging a cut roller; and, if youre 'late' or delayed in tipping out you can get 'tears', etc. in the surface. So, if youre going to use the 'tip with roller' method, you cant do this on the whole hull side and the barrier will start to 'kick' before you are finished tipping when its 'warm' outside.
The polyethylene trowel 'forces' the flow-out.
