I'm in the process of ripping out my carpet to install Pergo. I did the kitchen in Pergo a couple of years ago, and the wife loved it so much she wants the rest of the house done in it.
In the dining room, there was linoleum, and then they put carpet right over the top of it. Under the linoleum was particle board, under that is the plywood subfloor. I tore up some of the particle board that was in bad shape, and I'll be replacing it. The rest of the particle board is quite solid, but it has chunks of the linoleum and glue that don't want to come off. I think the black stuff that is stuck is part of the linoleum sheet; the top part popped right off.
What's the best way to get this black stuff scraped off? I tried a heat gun with disappointing results.
