The more I look at your handy work, the more I like it, and the more I want to do mine (what I can) the same way.
Earlier on you said:
quote:Then I use a 4 inch grinder with a thin 6-7 inch masonry cutting wheel(wear gloves) Just run the grinder back in fourth keep going horizontal(slight tilts are good to) lines from 1/2 to 1/8 apart, you will cross the line above and below the one you are scoring, it will look more realistic but try not to cross two lines while scoring if you can. try not to go to deep or you will need a sprayer to get paint in the cracks later.
A couple of questions, if I may:
Did you cut the foam with the wheel, as you said above, while in the train room? Wasn’t there a lot of ‘foam’ dust?
Did you paint right over the foam or did you apply any plaster or similar before painting?
Thanks!
