- The room is treated as a rectangle unless you enter a cutout area.
- Installed area includes waste, cuts, and pattern scrap before rounding.
- Plank count uses actual face coverage, while box count uses carton coverage.
- Rows estimate how many courses fit across the selected run direction.
- Metric mode uses meters, millimeters, and square meters for all inputs and outputs.
Hardwood flooring is milled from one piece through its whole thickness, so you can sand it and refinish it during its long life Scratches, lines or changes simply require new surface, and then you restore the floors instead of replacing them. This is the main advantage over laminate and engineered alternatives. Engineered wood has synthetic core under real wooden skin to lower the price, but solid hardwood is made of pure oak for that classic wood look and feel.
Oak is the most used material for hardwood floors. It is relatively hard, durable and stable. The nice natural grain of oak adds warmth and charactre to the room.
How to Choose and Install White Oak Hardwood Floors
White oak especially suits, because it works almost everywhere.
Well done floors from wood serve decades. With good care hardwood floors in houses can last 50 years and more. Hardwood floors also make the space seem bigger than actually.
You recognize quality floors according to species of wood, thickness of wear layer and type of finish.
For install hardwood floors you require some special tools. A pneumatic floor nailer is needed, and renting it without air compressor is too hard, so better buy a reliable nailer for oak floors. Air compressor give power to the tools.
Compound miter saw and little jobsite table-saw answer for all involved cuts. Pry bars help to remove old floors, tack strips, baseboards or trim. Floor scraper and sander are useful for leveling the subfloor and ensure smooth surface.
Tapping block and rubber hammer are necessary for tapping boards without damaging them. Oscillating tool eases work at door frames and other cuts.
Above concrete subfloors you must first lay moisture barrier. One mode is seal the concrete with Drylok, later add vapor barrier and then the floors up. Other way is lay sleepers, put insulation between them, plywood subfloor and ultimately the hardwood on top.
It is smart to leave the floors acclimate inside before the installation.
Prefinished floors have seams at the edges, so you must space them exactly. Overtime those seams blacken, and the boards can warp or split. True hardwood flooring, that is sanded and finished locally, gives smooth surfaces from wall to wall.
For three-quarter-inch prefinished white oak floors you require three-quarter-inch interval between all vertical surfaces, what matches the national recommendation of the National Wood Flooring Association.
