Building home-entertainment centre/shelving area with maple veneered mdf,
but need advice on finishing options. Want a finish that will not yellow the
wood, and can be applied by pad/cloth rather than brushing. Dont like
varnishes. Was considering Tung Oil, but read that this along with all other
oil based finishes yellows with age, and water-base treatments would be
better on light wood. The article does not go on to explain what water-based
finishes there are.- can anyone advise ??
According to Michael Dresdner in The Woodfinishing Book, the common
wipe on finishes - shellac, Danish oil, Linseed oil and Tung oil -
have an amber colour. Wax has a tan colour.
I suspect that the water based finishes will be either acrylic or
polyurethane varnishes. Polyurethane is supposed to give a bluish
colour and acrylic is supposed to be pretty well colourless.
I've used water based acrylic on oak, because I didn't want the amber
colour, and the results seem fine to me. Using a paint pad produces
much better results than a brush.
If the wood does not need any protection try wax (natural wax, not the
furniture polish that contains silicones).
The best thing to do is to try the finishes on a spare bit of wood to
see which one you prefer.
Tung oil in a commercial mixture (I use Liberon's Finishing Oil) is
barely coloured. There is a tint, but it's nothing like linseed, or
even pure tung. The better your application technique, the lighter it
comes out (i.e. don't leave excess oil on the surface).
For light use, I finish maple with a hard plain wax. I use Liberon's
"Black Bison", which is the other finish I use in huge quantities. Use
the "neutral" colour which is white, rather than "clear" which is a
Water based poly varnishes are water-clear. However they give the
usual "Airfix kit" plastic sheen of poly.
If you want a truly invisible finish on maple, you're going to have to
look at spraying it.

I've been quite pleased with the finish i've obtained on veneered board using
1. a coat of acrylic water based sanding sealer rubbed down with 400 grit. 2.
two or three coats of water based acrylic finish (in this case Aqualac
semi-matt) each coat again cut back with 400 grit. All applied with a foam
brush 3. a light coat of wax.
Gives a reasonably deep sheen without altering the colour too much.

Very similar to how I have finished Maple veneer.
I hate the streaks water based finishes leave but love the easy clean
up and the fast drying. I had tried various brushes, pads and foam
applicators seeking a cure but all to no avail.
Recently I experimented adding more thinners (expensive stuff ) and
found 10% helped cut down on this problem
I don't bother going down below 240g between coats when sanding but
finish off rubbing the wax in with 0000 wirewool.
I use satin instead of semi matt and as you say it gives a nice
The Liberon wax I use has a very pleasant odour which always pleasant
Water based finishes IME are almost completely colourless. In the past
when I wanted maple to look a little aged I found a standard oil based
varnish gave a slight yellow tinge which seemed to do the trick
