What Is BCX Sanded Plywood

SHORTGUN

I would like to put Plywood down on the floor of my shed and would like to know what BCX Sanded Plywood is and if one could used it on the floor of my shed?

What would you recommend?

JonM

For a shead...I would go with CDX

Plywood grades are determined by the veneer quality on the face and back of each panel. The first letter designates quality of face veneer (best side), while the second letter denotes the surface quality of the back of the panel.The letter "X" simply indicates the panel was manufactured with exterior type adhesive.

"A": Highest grade quality available. Can be defect free or contain small knots, providing they are replaced with wooden plugs (the fillers having a "boat" or a "football" shape) or repaired with synthetic patch. This grade may contain occasional surface splits that are repaired with synthetic filler. The surface is always sanded and provides for smooth paintable face quality.

"B": Second highest quality veneer grade. Normally a by-product of downgraded "A" quality veneer. Solid surface, but may contain small diameter knots and narrow surface splits. Normally repaired with wooden plugs or synthetic filler. Surface normally sanded smooth.

"C": Considered to be a lower end face quality, but a reasonable choice for general construction purposes. May contain tight knots up to 1½ inches diameter, some open knot holes, some face splits, and discoloration. Some manufactures may repair the defects with synthetic filler. Panels typically not sanded.

"D": Considered to be the lowest quality veneer and often used for the back surface for construction grade panels. Allows for several knots, large and small, as well as open knots up to 2½ inches diameter. Open knots, splits, and discoloration are acceptable. "D" grade veneers are neither repaired nor sanded. This grade is not recommended for permanent exposure to weather elements.

Very informative and in other words YES

Will the plywood be exposed to the ground beneath?

May I ask why you would go with CDX?

Isn't that like OSB?

What I am trying to get away from is the chip that may come off after a few years of wear and tear on the floor.

I do know that I want to go with 3/8 inch.

Is there anything call O C 4 from Georgia Pacific it say first floor on the boards.

SHORTGUN

The shed is up and finished, but I would like to have a floor that does not look like OSB.
What I am going to do come Spring is Prime and Stain the floor to seal it.

3/8 is too thin. I hope you put 6 ml poly below the plywood across the joists. Paint the floor and it will last longer. I would double up the plywood now.

OSB is Oriented Strand Board or lots of small chips glued together. Plywood(CDX) is cross laminated veneer sheets with a (relatively) smooth surface.

SHORTGUN

Yes I have 5/8 inch flooring as the floor and nees 3/8 inch CDX as you said, that I was not sure what CDX was.

I not sure but the Stain that I am going to use is for DECKS and is $40.00 a gallon.

JonM

Expence and its a shead...why go with something only you are going to see...what do you use the shead for...tools or is it a getaway from the wife shead?...

SHORTGUN

This is more of a Workshop ( WOOD ) and yes I will store some outdoor tools in it.

Good idea getting away fromthe wife.

What do you thing of 3/8" CDX?

I do have electric in it and looking for the best heat source I can find to heat 200 sq.ft..

JonM

How about going to your local dollar store and get a bunch of this stuff...make it easy on your legs standing all day

SHORTGUN

I belive that TSC has something on this order but allot bigger I belive 4' X 8'

I also am looking to build a workbench out of Oak which would be on edge and put together, I was thinking of 24" wide and 13' long how thick would you make it, and how would you put it together?

BCX, CDX,A,B,C,D, and the word YES has been used, OSB, O C 4, X, and then a reference to WOOD was used, TSC, then became the LETTERS OF THE DAY….
Why not just get some good old plywood, glue and nail it down and paint it with left over paint from grandmommys” garage pantry

Kingfisher

CDX is the common choice for floor in sheds and subfloors in homes. It is the same as BCX except for cheaper grades of veneer on the outside one has a C and B grade layer and the other has a C and a D grade layer. OSB in the sheet good made of chips of wood and in my opinion JUNK. I had assumed this was going down on the floor joist not over an existing floor and if so I would only use 3/4" if you are doing something else I need you to give a little more info please

SHORTGUN

I may have CDX for it states on the board (FLOORING) is there a CD4 or something like that?

I know for sure it states on it flooring and it is like tung and grove,I hope that his helps you?

Please ask me what information I need to gave, not sure what information you are looking for.

CDX is not like osb. osb is like osb. lol.
it's C grade on one side, D grade on the other and then the X i think is for exterior, even if it's not marine ply. they still call it that. i could be wrong on the X but someone correct me if i am.

plywood is so cheap these days with the amount of plys they put in, i hate even 1/2 for anything but walls and if you dont' request 4ply 1/2" it's crap.
3/8 you can just about punch through.

go with CDX, paint it

X is the glue. Exterior glue

I love this detail.. I hope that was something that you had sitting in the back of your mind, and not something that you had to research. Either way, that's some good information. Although, I've never seen ACX with plugs on the "A" side.
