Kapur - what surface treatment is needed?

I am building outdoor stairs of kapur, which is said to be resistant against most things except soil.
Can anyone tell me what (if any) precautions I should take when/before assembling the stair; both kapur/kapur, kapur/treated pine (used under decking), and kapur/galvanised steel?
Further, should I use decking oil - or anything - on the stairs?

Will be watchin this thread with close attention as Ive just started working with Kapur... interesting grain and hard as buggary... the resistance thing is why Ive chosen it for the keel of a boat and the fact that the Malays and other Indos have been using it for that reason for centuries helped!

Good luck with the stairs mate they should look the ducks knuts when your done :cool:

I haven't played with kapur in years; I worked for a while in a joinery that used it mainly for door sills. Heavy and very hard-wearing... perfect for sills.

When working with it, be wary of two things: it's one of those woods where splinters infect easily and it also stains the hands after a few hours of handling freshly cut surfaces. That's the way I remember it being anyway.

A decking oil would be a good idea, it's not the prettiest wood when naturally weathered.

Oh yeah... it plays havoc with tools. Be prepared to do a lot of sharpening! :D

Thanks, I have already noticed the splinters. Two fingers infected so far. :eek:
I used a cheap jigsaw on it - but had to upgrade. Since I did not think of just better blades, I bought a quite nice jigsaw, too. ;)

Decking oil on visible surfaces, ok. But do I need to protect the kapur against the treated pine?

Of course you do!! That pine is real nasty stuff to other timbers specially that treated type... and with foreign timber well its downright murderous! :eek: :D

No, there's no need but if it makes you feel happier... ;)

IF I was a rich man with plenty of time on my hands, I'd like to try oiling all the surfaces of the decking during assembly. But then again I'd also like to try my hand at hand-cut secret dovetailing of all joints, inlaying the railings with ebony stringing and pearl inlay, generally making a white elephant.

But it'd be my white elephant. :D
