re: Laying New Floors - OB Recs

If you are going with wood flooring on a wood subfloor I would remove the hardie use a long level and mark you low spots. Buy a floor leveler thats designed to go straight on wood. Henry makes one that should be carried locally.

Follow the directions. I would cover the entire floor to insure a smooth surfance instead of just the marked spots. But start at the low areas and let it spread from there.

You can glue down, nail or if you want glue and nail your wood floors down.

Whatever you decide get your floor fixed at the problem, not 2 or 3 layers up. Its much easier.

Edit: forgot to say. I dont do floors professionally, but I have done about 6 or 8 . Everytime i started with lips or bellys in the subloor and tried to address it a layer or 2 later I regretted it. when I used henrys to start everything went fast and headache free.
