I didn't think it was possible to do this with foam. Proved me wrong...once again. Not bad, not bad at all.
Yes. But what's the cost of all that foam compared to the old wire screen/woven cardboard covered with plaster technique ? All that, at least below the track, I'd do as old method. Perhaps above the track could be foam..I mean foam is really costly ! And without a shop-vac constantly on, and hose kept at all foam cutting/shaving sites, it's a bigger mess than the plaster method. This does not mean Mark's final outcome is not good. Looks great when done. But the cost.....ugh.
