    How to Fix Plywood Face separation

    Building some base cabinets for my bathroom remodeling project. I decided to save 8 bucks a sheet and purchase the cheaper (made in China) 3/4 Birch Ply at my local HD to build the shell. I am having a problem with the face veneer peeling away from the core laminate while I am assembling the cabinets. Either I am not being careful enough with the edges or the plywood is real cheap. Too late to change to the good stuff.

    Does anyone out there have a favorite technique for fixing this problem? Most of the splintering is on the edges but is wide enough (1/2 to 3/4) to require some "re-glue". Trying lots of different things but hoping someone has a foolproof solution.

    Best of luck to all in the coming New Year !!!!

    Since you're using those panels, re-glueing is your best bet. You could use a glue injector (plastic bottle with needle on the end), a small paint brush, tooth picks, just about anything to get the glue as far in as possible. Use a yellow glue (like TitebondII) and clamp until dry. Check all the edges before you start fabricating. You might check the whole sheet to see if any of the veneer is loose besides the edges. If it's that bad, take it back.

    RE: How to Fix Plywood Face separation

    Is the edge showing tearout (as from a saw), or is the veneer peeling away from itself, or is the glue joint separating? Sounds pretty unhappy, whichever it is.

    If you're going to oil or paint the cabs, you could get some hardening oil (as in linseed or Danish oil) into the edges. That'll help strengthen the fibers there if the glue joint itself isn't separating.

    If it's tearout, you can straddle the cut line with one layer of masking tape before you make the cut - that helps a lot. When you pull the tape, pull it toward the freshly-cut edge; that tugs the fibers lengthwise instead of straight up off the surface.

    If the glue joint is separating, be REALLY LIBERAL with whichever surface treatment you use. Otherwise, the moisture from your bathroom activities will help it delaminate more. This is particularly important if you don't have a fan in the bathroom.

    RE: How to Fix Plywood Face separation

    Thanks for the info folks!

    Tim, The problem is the face veneer de-laminating at the edges. Not as a result of the cut but probably from not being careful enough moving it around the workbench. I was going to finish the cabinets with stain and then a polyurethane (MinWax Helmsman). I am hoping the poly will help secure the edges and seal them. In the meantime, I have been smashing some Titebond in there and clamping them. Seems to work well just a pain in the arse !

    Regards,

    Richard

    Well, what is going to happen later on then?
    You are sticking your finger in the dyke, but not repairing the dam.
    I got some of that Chineezy plywood for shop projects (shelves and such).
    It is really unstabile and cannot be relied on for project stock.
    Better to use MDF and seal it well. Or go ahead and get better grades of plywoods and with waterproof glue.

    Otherwise you wind up penny wise and project foolish.

    8 bucks a sheet. Are you crazy man? http://smileys.smileycentral.com/cat/10/10_5_136.gif
    Live and learn. You get what you pay for. Now start over. Use that vanity for a shop cabinet. ;)

    Those are nice, Richard.
    Damn shame. Damned material anyway.
    Yup, lesson learned. I wish you had learnt it the way I did, in the shop where you can burn it before anybody knows. }>
    They look fine from here though. Maybe you are sweatin small potatoes, huh?
    Got to be a lot better made than Ikea. ;)

    RE: How to Fix Plywood Face separation

    And I shoulda known when I walked in HD to buy the stuff. It had a stamp on the edge of each board that said "Made in China". But you know how that goes....I saw the stamp and all the wife saw was the cheaper price.

    The lesson I really learned here is "DONT TAKE THE WIFE TO HELP PICK OUT MATERIALS !" :D :D

    Sonny,
    Your right.....8 bucks and a lesson well learned. Unfortunately, I dont have room for any cabinets in the shop and the ones I built are already complete....

    Just going to stay on top of the splinters, be more careful and learn from my mistakes for next time......

    Attached are the cabinets in question.....

    Richard :D
