Varnishing Luan

Out of curiosity I sanded a small sheet of "philippine mahogany" (luan) and applied some varnish. It just sat there, dead.

Some people insist on useing it in boat building and I guess because its a mohagany its expected to look pretty and hold up well. NOT.

It is what it is...
Its light, its easy to cut, ITS CHEAP...
Its underlayment for residential flooring, and works well in this function I might add. Its good for all sorts of stuff that is not exposed to weather or water. Its great for making patterns, even lofting when painted flat white.

But at about nine bucks a sheet its really just 3ply cheap plywood. It is what it is...

Philippine mahogaqny is a registered trade name...ain't real mahogany...it's a poor grade cedar...but there's lots of it so it's cheeeeep....and it fades in direct sunlight. where it is exposed to direct sunlight it may be stained to appear like real mahogany but the stain will require a heavy U.V. reflective varnish.

I never said you couldn't varnish it.

Years ago I repaired a raised pannel wainscoat in a library that somebody buit out of laun plywood and mohagany trim. whoever did the work did a really nice job. A leaky bathroom on the second floor ruined two of the pannels and I was able to replace them and lay on about 10 coats of varnish to match existing.

He means it doesn't look very good when you varnish it. He's right. With a heavy filler stain it's sort of OK, but not like real mahogany.

It was to cover the end of a bathtub, if you really want to know. It just made me appreciate how a little varnish will make mahogany stand up and dance. Even some other woods perk up, but not this stuff. Don't worry boyz, it's not going on the boat. I'll either get some mahogany ply for this tub or else just tile it over.

Trade name?.. does it not come from that part of the world?

Not a "real" mahogany?..
What is a REAL mahogany? and where would it come from?

it's a poor grade cedar...
Is this some sort of violation of truth in advertizing?

I admit to buying mahogany and not knowing much more about it than it looked like what I thought it was sposed to look like, and since it wernt a govmint job and didnt require cert's I was happy with it. Guess I coulda been fooled huh...

Is it the wood that turns yellow or the varnish?

mahogany
n 1: wood of any of various mahogany trees; much used for cabinetwork and furniture 2: any of various tropical timber trees of the family Meliaceae especially the genus Swietinia valued for their hard yellowish- to reddish-brown wood that is readily worked and takes a high polish [syn: mahogany tree]

Mastercraft makes a polyurethane gel wipe-on stain that works well for something like this.

Gary......Luan is a tropical cedar, the primary variety comes from the area of batangas province in norther Luzon, Philippines...
After former president for life Ferdy Marcos virtually destroyed the forests of Tanguille (the closest thing to honduras or the prime grades of African mahogany)primarily to chris Craft, substitutions were made of Luan because it is a very close cousin of tanguilli, looks and smells very close to tangulli...and stupid Americans didn't know the difference..at first...so they registered a trade name.."Philippine mahogany" and advertise Philippine mahogany...and after decades of delivering Tanguilli...who would think twice....great marketing ploy...and most American retail lumber yards dunno the difference. the wood Luan turns urine yellow under direct sunlight unless varnished and stained. it's a natural function of the wood and natural dyes....it doesn't have the strength and rot resistance of real mahogany or Tanguilli.....

Thanks Palidin, very interesting...

Reminds me of the steel shortage days when a saleman called on a customer and actually had some stock, the customer asked what kind of steel probably meaning what alloy, and was told, It's the kind that when ya thro it a bucket of water it sinks. Good nuf, SOLD [img]smile.gif[/img]

Sounds from what you said Paladin that sometimes when you buy mahogany you're actually getting luan.

you must specify honduras or african mahogany and should well know the specific species......if you are offerred philippine mahogany you ain't getting the real thing...

"True" mahoganies are all Swietenia spp.

The old "true" mahogany of the 18th c., aka "Cuban" or "West Indian" mahagony is S. mahogani. It's essentially no longer a commerical species due to over harvesting and habitat loss.

These days, true mahogany passes for []S. macrophylla[/i] (big-leaf mahogany) or S. humilis (Honduran mahogany). Mostly S. macrophylla since both S. humilis and S. mahagoni are CITES-listed and so largely unavailable.

There are other Swietenia species out there, I believe 6 in toto. All of them are native to Southern Florida, the Caribeean and/or Central/South America.

Khaya spp. is sometimes referred to as African mahogany as they are cousins (both are family Meliaceae.

Luan aka Phillipine mahagony is Shorea spp. (family Dipterocarpaceae), of which there are a bunch of variants. Not a cedar. Not a mahogany.

True cedars, OTOH, are Cedrus spp. (family Pinaceae. That would be 'pines'). There are four true cedars:</font>

• C. atlantica "Atlas Cedar", native to the Atlas mountains of Morocco. Some people class it as just a variant of C libani (see below).</font>
• C. brevifolia "Cyprus Cedar", native to some 500 hectares in Cyprus. Again, some class this as a variant of C. libani.</font>
• C. deodar "Himalya Cedar", native to India and Pakistan&mdash;the Western Himalya and South slopes of the Hindu Kush. Again, some class this as a variant of C. libani.</font>
• C. libani "Cedar of Lebanon", native to Asia Minor.</font>

And false cedars, tend to be either Calocedrus spp. (incense cedar), Thuja spp. (arborvitae) or Chamaecyparis spp. (white cedar/false cypress).

Thuja includes Western Red Cedar. Chamaecyparis includes Alaskan Yellow Cedar, and Calocedrus includes California post cedar and incense cedar.

There.

Hope I've confused you sufficiently.
