I've often wondered how furniture gets the surface treatment it does during manufacture. For example, flat pack wardrobe/drawers etc from MFI all have a nice coloured finish which when viewed on end-grain cutoffs (for little shelves in wardrobe) can see its soaked a good 1 or 2mm into the wood. These bits of wood are perfectly smooth without any of the 'texturing' I've got with ours.
This raises the question - how do they do large bulk colouring/finishing of pine which will penetrate well (not just a shallow/skin treatment) and also doesn't raise the grain? They can't be sanding everything down after treating can they? Wax? Surely waxing is a high labour thing - and this appears to be 100% uniform covering - no signs of differing colours or anything.
