How do you remove nailed subfloor from plywood?
One method is to use a small hole saw and drill around the nails, just the thickness of the floor. Then (after getting the sheet of plywood up) you end up with a bunch of small plywood plugs you can break off the screws/nails fairly easily, and enough nail/screw to get a grip on for removal.
Is it OK to put plywood in the attic?
An attic can be floored with 1/2″ CDX plywood, if it is being used only for storage. However, the same can’t be said if you are planning on using the space as a living space. In that case, you will need to use 3/4″ thick plywood. The building code allows for the use of OSB in place of plywood for subflooring.
How thick should plywood be for attic storage?
Joist Spacing and Attic Use You need 3/4-inch plywood. The thinner plywood is acceptable when the joist spacing is 16 inches. If you plan to finish the floor in the attic and turn the room into a living space, however, you should always use 3/4-inch plywood.
How much does it cost to put plywood in attic?
A contractor will charge $550, which includes labor and material, to lay a plywood floor in an area approximately 10-feet square. If you have basic carpentry skills and tools, you can do the job for $190, the cost of the plywood and screws.
How do you remove old plywood?
Insert the prybar anywhere under the next adjoining piece and pry it up. Continue inserting and prying until that side is loose. Lift the plywood up as you did before. If the pieces are stubborn and won’t release, kick the plywood with your foot while holding it up, or hit it with a hammer to loosen it.
Is OSB better than plywood?
Wood fiber is used more efficiently in osb. Osb is stronger than plywood in shear. Shear values, through its thickness, are about 2 times greater than plywood. This is one of the reasons osb is used for webs of wooden I-joists.
Can attic joists support a floor?
The answer, in most cases, is a definite yes. Even though it wasn’t put there, the joists supporting your ceiling are quite strong. Putting down flooring won’t stress them any more than the floors in your bedroom, kitchen, or bath. We would, however, suggest you get help bringing the flooring up into the attic.
How do you attach plywood to attic?
Carry a piece of plywood to one of the far corners of the attic and lay it on top of the installed boards. The plywood should be perpendicular to the joists so that a signal sheet spans multiple ceiling joists. Cut the plywood to fit so that each end of the plywood boards lands at the exact center of a floor joist.
How do you remove a glued down subfloor?
Use a hammer to drive them back through the plywood and then pull them out from the top with the hammer. Pull all remaining nails out of the floor or floor joists using a claw hammer. If the nails break off, use diagonal pliers to remove them.
How do you remove a water damaged subfloor?
Start by completely removing the damaged materials. Use a circular saw set to 1” depth to cut the subflooring back beyond the damaged areas until you reach solid structural framing. Use a pry bar to remove any protruding nails and vacuum up the demolition debris.
Can you replace subfloor from underneath?
1. Your floors are uneven or sunken in parts. If you notice a soft spot under carpet or wood flooring, it could mean that the panels below have weakened. While replacing the entire subfloor may not be necessary, you will have to replace the damaged pieces to prevent the rot from spreading.
