Microshades H4 sleeper

[jerlinjames]

Hi all,

I recently bought a Microshades H4 sleeper from http://www.bunnings.com.au/microshades-sleeper-h4-200x50mm-1-8m_p8423137

As I dont have a jointer/thicknesser I sanded it back a little.

I was wondering if this can be used for making some kitchen stool legs and seats? Reason I ask is because it is H4 and wanted to know if it will be suitable for inside the house after shaving off the top layer and finishing it off nicely.

Also how far do I have to shave back or plane back before I get rid of the H4 effects on a peice of timber like this..

Here is a professor google search

anyhow i was under the correct impression that treated pine is pressure treated. CCA is bad for things that kids can chew/suck and LOSP is not a lot better but doesn't impregnate the wood as much due to lower pressure treatment.
apart from that,

micro shades is just a pigment(colour) added to the above treatments

No. Sleepers treated with CCA, LOSP and other anti-fungal, anti insect treatments should not be sanded without proper precautions...especially the newer stuff as no-one knows what the long term exposure effects are. At least with CCA you know that the body can process and excrete arsenic, so if you're not eating a cupfull a month you're within what your body can handle.

Really, the same precautions (or more) should be taken for old railway sleepers as no-one knows what they were treated with or what built up on them in service (DDT, anti fungals, asbestos from train brake linings, diesel, diesel particulates, creosote etc etc).

Plus treated pine sleepers are generally made of really low quality timber. If you want cheap furniture timber, hand select good bits of framing pine and laminate up to the size required.

Thx guys,

decided not to touch this stuff with a sanding paper again.

probably attempt making a outdoor stool out of it as it is, paint it and be done with it.

you learn something everyday :)
