I am going to be installing ~1400 sq ft of 3/4" x 4 1/2" engineered plank oak hardwood flooring. I am going with the 3/4" stuff because it has a fairly thick wear layer, so that it can be refinished several times. I haven't bought the stuff yet, but I have been reading. The installation will be over 3/4" T&G plywood for most rooms and ~300 sq ft will go over a below grade (4' below) concrete floor. The concrete floor has never exhibited any moisture problems.
I am interested in comments and hints from those who have used 3/4" prefinished engineered wood, particularly from either Capella or Muskoka/Tembec. I would also like to know if there were any quality problems with these two companies, if you used their products . (I can't find much pro or con discussion on the net.)
Since I expect that I will be doing the job over several months, I intend to buy rather than rent a pneumatic floor nailer (PortaNailer) to nail the planks to the T&G. According to both manufacturers, this is acceptable with this thickness.
Several questions: How well does the engineered stuff nail? If you have used Capella or Muskoka, how was the material? Was there a lot of bad pieces? Was the grade what you expected? How well has it held up to traffic?
I don't feel like laying down underlayment on the concrete and then nailing the planks down. This will raise the floor by 1 1/2". I think I will be gluing down the planks directly to the concrete. If I have to nail to underlayment, I think I would go with the floating underlayment method which lays down two staggered layers of 3/8" sheets nailed or screwed together, and nail or glue to this. Anyone tried this? It does not seem to be a very common method.
Anybody glued down on concrete using the 3/4" planks? How bad was it? What did you do to make sure boards were tight fit?
Roughly how long can I expect it to take me to complete a good sized room. I am reasonable handy, and I have most of the appropriate power tools; I do intend to buy a miter saw to supplement my table saw.
Any other hints I can use to make the job go easier?
