Lightening dark stained beams?

Currently embarking on a major refurb of the living room.

There are two stonking timber beams across the ceiling (about 8" square
by 13' long), which a previous owner has covered with a very dark, shiny
varnish of some sort: http://oi58.tinypic.com/2hs42zl.jpg

It Has Been Decreed that these beams should be rendered paler and
natural; AFAIK they are pitch pine, so in theory ought to look like this
fireplace lintel, which was made from original timber taken from
elsewhere in the (100-year-old) house:
http://oi59.tinypic.com/15n603m.jpg

Anyone got any bright ideas how to do this? I can't imagine any form of
chemical stripper is going to get them back to natural colour; and
sanding that amount of area at that height seems a non-starter too.
It's difficult not knowing what sort of varnish (or whatever) has been
used before

Was wondering about cladding them in veneer or something?
Thanks for any input...

The only way will be to take some material away as the stain/varnish
will have soaked in to some extent. Messy job but sand blasting would do
the trick.

empty the room and grit blast them

Only sure way.

Sand-blasted old timber always looks godawful, usually found in stripped-
back "theme pubs".

But probably not as bad as veneer...

Lobster - if veneering them'd be acceptable, wouldn't painting them?
Somebody's painted the beams in a few of our rooms - more of a wash than
a coat of paint, and it looks very, very good.

No chemical will get them so pale, and as you say, mechanical (sanding etc)
is going to be time consuming and quite likely unsuccesful.


I'd clad them in 9X1 (or whatever) and apply a clear, matt varnish.

Failing that, I'd clad them with plasterboard, fill and sand, then paint
white or whatever colour the ceiling's going to be

Dab it with some washing soda on a sheet of kitchen roll. If the colour
comes off on the paper, your varnish is probably an alkali soluble resin
which, in theory, is strippable in situ.

Veneer will look even worse IMO.
The only way to get it off is by chemical stripping.
Do a small area first so you can see what you get.
Tedious job. Some stuff comes off in lumps, other turns into glue (bloody
awful to remove.)

And ideal job for She Who Has Decreed.
It will be a good lesson WRT any further decrees that may be in the
pipeline.

We have similar supporting Pitch Pine beams in our Victorian farmhouse.
At some point, possibly 1938, they had been coated with a product called
*Darkaline*. When we renovated the place in 1995 this was cleaned off.
Unfortunately I can't remember the actual technique used.
Either heating with a hot air blower and scraping with a triangular
scraper or the original Nitromors plus scraping. The rest succumbed to
an orbital sander.

Although described as a *stain* there was very little actual penetration
of the wood.

Actually pitch pine takes peroxide bleach very well. It's getting back
to bare wood that's the problem

Shiny means little penetration, so it should be possible, just a question of trying the different options.

Tim mentioned 1930s darkaline. I suspect that would be aniline dye; if so its susceptibilities can be looked up.

They only work if the varnish is animal or vegetable derived. Modern
synthetic products are unaffected. And, if they do work, very difficult
to stop them obeying the laws of gravity

Tim Lamb formulated the question :
I had some success with a rotary wire brush. It left the wood surface
rather uneven, due to variations in hardness due to the growth, but
once re-varnished the effect was quite good.

Ahem indeed! I'm obviously out of date. That was traditionally a caustic
based product so I guess they've switched the formulation to the
non-hazardous (and some would say non-working) eco-friendly gel stuff.
Same applies about working overhead though. If it's dissolving the
surface coating, how do you keep it up there?

You are going to have to experiment to discover what is there and how
much material you will have to take off to get to original wood. It
might not be that bad but to work at height you will need a platform and
a fairly potent sander. You might get most of it off with a hot air gun
and a scraper provided that you don't scorch the wood and then sand to
get the last bits. Chemicals might work but you will need good eye
protection and rubber gloves and the results can be uncertain.

Whatever you decide to do try it out on a hard to see corner first!

Up to you I suppose but original wood will look better. Pitch pine can
have nice detail grain if sanded back but it is incredibly tedious.

The only worry is that the dark stain is there for a reason and the
underlying wood looks like it has been through the wars.

Consider if "woodgraining" it would be an option? (There must be a better term
than "woodgraining wood" -- but google does find what I mean.)

This making a faux woodgrain effect with pigments and binders. Originally it
would have been done with a pale oil base paint to match the lightest bit of the
wood you are traying to imitate. Then the darker bits were added. (Originally
using a mix of pigment in stale beer: This allows the grain to be worked, wiped
off, redone until satisfactory, and it would dry to s surprisingly resistant
finish.)

A lighter base, darker oil glaze and a paintbrush will also do. I was admiring
nice wainscoting once, complete with panels with symmetrical grain patterns
where the boards were sawn and joined. Then noted that the woodgrain did not
match the run of the wood, and that it also extended across the metal hinges...
all done with a bit of paint:-)

So that would mean practice a bit, paint it, done.

(Anything is better than sanding overhead. Tried that, using a large belt sander
on a ladder...)

Looks an interesting product, having explored their website. I suspect it
wouldn't work for me , since as somebody pointed out upthread, the stuff is
likely to have penetrated the timber.

Thanks for all the replies to my query. There are a few I'd like to try but
I'm loathe to experiment as there's nowhere invisible where I can check
them out, without bollocksing up the beam if I decide it has to stay as it
is.

We have these beams in two other rooms; in one of which we've kept them
dark, and in the other we painted them pale. Those look shite!

I'd be up for hiring someone to do this job

That was *Darkaline* on pitch pine.

The *joists* are superficial: old pine, grit blasted and then screwed to
the underside of the real floor joists.

Blimey that was a long time ago...
I remember in a very old building in the town centre here, the shop who
leased te ground floor lightened the look of the beams and the people from
the council told them it was a conservation area, and they should not have
done so. Round that part of town you even need to ask the council what type
and look of new windows you put in.

Err then you end up with _smooth_ beams which would not be at all in
character. In fact some of ours have cracks inches deep which someone
has carefully worked paint into.

I've heard the best technique is sand blasting, but using dry ice. And
it required the house to be emptied.

It makes a godawful mess, and leaves the grain all scored. Better to
belt sand and then add the grain in later with some coarse sandpaper!
