How to install hardwood on a rough floor
I have been installing hardwood for customers for a few months and
things have been going well but seems I met my first challenge. When I installed 4" wide 3/4" thick mahagony flooring there is excessive height difference, maybe upto 1/10 of an inch in rare cases, between adjoining boards. I investigated and found this is due to the chipboard (3/4" OSB) floor being very rough. Even though there is 1/5" thick plywood on top of the OSB the problem persists. To correct the problem do I sand the OSB floor or smooth it with floor leveling compound? Or is there another solution? |

When I put down a Pergo floor a few years ago there was a requirement for the floor to be no more than 1/8" (or something like that) out over 6 feet. I had a place or two where there was a valley and used Jif-Set with vinyl sealer to level it. I found it to be not quite as self-leveling as described and used a bull float for additional leveling. todd |

Bizarre! Could you have some boards upside down? The T&G is not always
symmetrical. ALso, the bottom face of the groove edge should be relieved to make the top edges close up more easily. Wilson wrote in message ps.com...
