Hardwood floors over old pine
We are contemplating hardwood floors in an 1860 house we are
renovating. It currently has two layers (1.5 inches total) of pine floor -- the rough-sawn subfloor covered by painted pine boards. Everything sits on 2 x 8 joists (older style) set 30" OC. I'm planning on tearing up the top layer of boards and putting down 3/4 T&G flooring (Advantech). But I'm worried that the amount of flex (bounce) in the floor from the widely spaced joists will cause problems down the road. Has anyone here tried anything similar? What luck? Thanks, John |

But I'm worried that the amount of flex (bounce) in the floor from the widely spaced joists will cause problems down the road. What's the dimensions of the present versus the proposed? Is it T&G or simply butt seams? What about the thickness of each layer? If the 1-1/2" is two 3/4" and the hardwood isn't some manufactured product for which I have no information for on stiffness, hardwood such as oak will be as, or stiffer than pine. If, otoh, the top level is 1" and the underlayment is only 1/2" (which would be most unusual for the age if it is original), then you would be removing material. Unless the existing pine is in really bad shape, you might consider simply refinishing it as being more in keeping w/ the age of the house. -- |

Hardwood floors over old pine
There are two layers of 3/4 boards -- the subfloor are wide, roughsawn
boards and the top layer is 8-inch boards butted against each other. The top layer is in bad shape -- painted many times, cupped in spots. We've been told it's not worth refinishing and I'd tend to agree. The lead dust alone would probably qualify the house as a Superfund site.

What about turning the top level over to the under side rather than losing all that history? -- |

And, btw, as another way to restore such vintage places -- in Lynchburg, VA, did these routinely of old antebellum houses in downtown during revitalization. Rather than sand in place which often would require far more material to be lost or difficulty, since we were doing bare-wall restorations anyway, we would take material such as this to a commercial shop w/ a thickness sander. W/ one of these dudes, it's a snap and working individual pieces is more material-saving than the whole floor. Some distress and marks are "character", not defects, also... Where are you located? If anyways close by, I'd take the material you don't want in a heartbeat... -- |

It had a 1 1/8" fir plywood subfloor and had slight bellies between the joists, but not too bad. I went over it with 1 1/2" strip oak and it turned out great. In your case I'd be a little concerned about the two layers of 3/4--though I really couldn't say for sure either way. 1 1/8" t & g plywood is readily available. You might consider that. Manufacturer's warranties aren't worth the paper they are written on. |
