I recently came across this company and their website and thought they deserved a wider exposure.
NB They are not
the company that used to be Holkham Paints.http://www.linseedpaintcompany.co.uk
Some interesting stuff there. I've not used their stuff but will certainly think about it for the future.
A small extract ...Acrylic cannot be reversed
This is a disaster for people with a passionate love of old properties. Acrylic paint and varnish cannot be removed with conventional paint stripper. Architectural salvage yards won't touch a door that has had an acrylic varnish applied directly to the timber. Ok, if you are painting your skirting boards you probably aren't worried about taking the paint off. But suppose you use an acrylic varnish on your beautifully stripped doors. And suppose you decide to use a coloured acrylic varnish because you want the yellow pine to be a deep mahogany color. Oops! That's when you discover that acrylic varnish sits on the wood surface and doesn't penetrate like oil or old polyurethene varnish. The colour sits on the surface and obscures the grain. Double oops! The acrylic varnish dries superfast and brushstrokes are clearly visible. Triple oops! Because it is so fast drying, overlapping brushstrokes double the amount of varnish on the timber and intensify the colour, leaving dark patches all over. Quadruple oops! Because it is water based, the water has been soaked up by the timber's fibres and they have become swollen. The whole surface is as rough as a badger's, well, rough bit. Now you have to sand the surface more than just lightly (denib is the trade jargon). Oops for the fifth time! (although by now it is swearing and blinding, not a genteel "oops") even a light sand takes plenty more off any high points (mouldings and corners for instance) and the colour of the varnish has gone, leaving light-coloured patches and lines all over the door as well as the dark patches where the brushstrokes overlapped. The job is done, it cannot be undone, and it looks like hell. Only thing to do now is paint it!
