  • Plywood- higher quality stuff?
  • dmorts
    Full Member

    I’ve got an idea for a simple under TV cabinet made from plywood. This will have the edges unfinished* to show the laminated layers, with the flat surfaces painted with a gloss colour. What am I looking for to get plywood that will look good in this situation and resist delaminating at the edges?

    *Well, I might seal them with something if needed

    Was there not someone who made a child’s bed/desk with something like that on here? Looked fab.  Somewhere in the ‘What is the last thing you made’ thread?

    hits back of head and tries to remember….

    Google “plywood grades uk” and that’ll give you an idea what you’re looking for. If you’re leaving the cut ends as you describe, then you’re looking for the grades with minimal voids in the layers – as these voids will show up as holes in a cut edge. And of course, you’ll always cut through a void. 😀

    You’ll possibly have to go to a specialist ply supplier as the grade you’re looking for might not be available at your standard trading estate Travis-Perkins etc. Also, prepare to do a bit of “wtf” when you see the price of a sheet of A-grade plywood.

    On the recommendation of a guy I know, I once bought gaboon ply….. it was £150ish for an 8×4 sheet! Great quality but so overkill for what we were doing (I also bought 3 sheets ((flipping idiot)))

    Gaboon ply is great when weight is an issue. This is not really a concern for the OP.

    You’ll be after a birch faced ply I’d have thought.

    I’d also consider staining and then finishing with Osmo (if you can source a small quantity – a bit spendy). Will look a lot less ‘homemade’ (in a bad way). You’ll end up with the colour you are after but a pleasing grain effect and still a good gloss/stain finish. Stain the panels oversized and then trim them to size to avoid bleed. Also cutting the panels to size – how you doing that? Putting masking tape on the cutline before cutting can help with the edge splintering.

    Birch ply is what you want. There are different grades. Expect to have knot patches or pay at least £100 to get an 8×4 long grain sheet with none on one face (birch trees are small and won’t have long sections of trunk without branches). You can buy the stuff with formica on both faces too.

    You’ll be after a birch faced ply I’d have thought.

    If its the edges that are on view (and the faces painted) I think you want birch all the way through – not just ‘faced’ – some ‘birch’ plywoods are veneered softwood.

    A lot of commonly available hardwood plywoods have a thin fine grained veneer and a core of plys that are a bit of a dogs breakfast when seen as a cut edge – the face ply’s are thiner than the core plys, the cores might be different colours to the face ply and each other, theres voids and crooked lines where spliced veneers have been overlapped. Standard hardwood plywoods tend to use a weird purple-y glue between the layers too. So – not that nice as an edge to have on view

    The commonly available plys that have the nice, even width, same material throughout plys are Birch (everyone’s favourite) and Spruce.

    Spruce is cheaper and bolder and a bit livelier (thinner boards tend not to want to sit flat so you need to consider that with what you’re building and have the structure hold itself flat and square. It has a brighter, bolder grain on the cut edge and not as smooth faced as birch – but in the right application it can can look really nice. Any cuts that go at and angle across the sheet (rather than straight along or across the board) can reveal some really nice chevron-like grain patterns on the cut edge

    ‘Wisa Spruce Special’ has a better quality face surfaces than standard construction spruce plywoods with a lot fewer, smaller knots  and can look pretty nice.

    Birch is usually double the price, much finer grained, much heavier and are stiffer, flatter boards. Probably easier to find than ‘spruce special’ with good face plys (as spruce is usually more commonly stocked for structural rather than decorative uses) you want to ensure its a grade with with low / no flaws and splices in the middle plys if you’re making a feature or the cut edges

    Less commonly available and less commonly thought of – as sort of best of both worlds – is  Poplar. A lot of standard plywood use poplar in the core hidden behind a far-eastern hardwood veneer – but ‘Efficiency Spanish Poplar’ has the same regular width ply’s thoughout as you get with Birch and has a face ply of good quality Poplar  that actually you’d have to look twice to see isn’t birch. But it’s half the price, feels like half the weight and finishes really nicely. Very very pale – almost white when in the raw and needs careful clean handling until you’ve put a finish of it – one bonus it has is it uses a pale, neutral coloured adhesive between the plys unlike the near black glue lines between the plys in spruce and birch and makes the exposed edges less pointedly stripey.  Looks gorgeous with a coat of OSMO – sort of iridescent around any small knots in the face plys

    Those particular grades of Spruce and Poplar are unlikely to be on the the shelf at you’re local timber yard – good Birch you’d have a reasonable chance of finding (you can even get it in B&Q on a good day.) However a good independent would order any of those in for you.

    If you have branches of Lathams or Timbmet then you’d get good options there. Meyers would also stock good stuff but harder to deal with as a cash-customer – but these are the people your local stockists would order from.

    I did a kitchen island in laminated birch ply.   Drop me a PM and I’ll dig out the supplier if u fancy. Usually commercial, but happily dealt with me.  Well priced (In comparison), after I shopped around.

    If it’s being painted  get someone to give you some birch ply off-cut rips, stick them on as a lipping and make it out of mdf…. 👍

    Hi, some very useful information here but does anyone have any experience with any places to buy decent ply in east anglia?

    If you wanted to use the easily available stuff, get hardwood throughout which gets you the higher number of thinner plies (think 7 or 9 rather than 3 or 5 thick softwood plies).

    You would need to experiment but you might be able to rough cut to size, and then fill any voids on the edge, and then either cut another very thin slice off the face to tidy it up (or sand it).  If you do the face edges first, you could keep cutting back until you get less voids.

    We have a lot of edges on display in a building project we’re doing. Not furniture use as such but it’s a good finish. We are using I think BB grade birch ply and have been getting it from Jewsons. There are a few plugs in it but the number is quite low and so you can nearly always select a blemish-free side to be visible. Our edges are good.

    There is higher graded birch ply than this available, but for considerable cost increase. We judged we could stomach far more wastage than we expect before that was worth it. And thus far no wastage because of the plugs as far as I know.

    You can do lovely stuff with ply.  Check out https://instagram.com/royandrupert?utm_source=ig_profile_share&igshid=1fee6q5a66j3o

    If you want to spend a bit more melamine faced ply will give a better finish than painted.  Needs very careful cutting though – good, fine tooth blade on a rail plunge saw

    Birch ply

    Find a specialist who will do you a cut list. You’ll get perfect edges and save a load of time. Working with a 8×4 sheet is not easy. If you do cut, use a router. If you are near Bristol then google Avon plywood

    As above, it’s birch plywood that typically has decent end grain and no core gaps. Marine plywood also has a neat end grain, but that tends to be more expensive and I’m not a fan of the face material. I’m making some shelving at the moment with 18mm birch plywood with an oak venerr on the face.

    Thanks, lots of info to digest! I am looking to make something very similar to alpin

    How was this joined, biscuit joints?

    Late reply….

    Just taped and glued. Couple of clamps to hold it whilst glue set.

    27mm ply.

    Easy.

    aircraft grade for perfect void free birch ply, as stated above, bring your spare wallet and smelling salts when purchasing

    nice mitre alpin, what was that cut on?

    BB grade birch ply would be fine, 8×4 sheet somewhere around £30 – £40 depending on supplier. Costs are going up fairly significantly this month though
