Anyone having luck with a crackling varnish for outdoors....and that'll stand up to time. Also how have you used it and what is it made up of.
Thanx in advance

Doug,
Now theres a great question.The very nature of a crackle finish is the fact that the paint is cracking and pealing off so you have to be ready for your finish to change over time.A classic crackel finish would be fat over thin.That means oil based over water based (glossy).Those finishes takes awhile to work.My favorite is start with any old rough wood and apply soft parafine wax to the surface.Then brush on the cheapest liquid car wax you can find randomly.Next mix up some cheap water based paint,add powdered pigment ,whiting or anything that will weaken the strentgh of the paint to form a strong skin,at that piont you should have a pretty thick paint mixture.Start globing it on skiping here and there.Also think about layering other colors on top of each other.let each layer dry,then reapply the waxes and then the colors.When all this paint finilly dryies ( it might take a few day) the paint will crack and peal on it's own.When it's dry take a wire brush and distress the paint.That when the wax goes to work.The paint will peal off in places where you put the wax.But you will be surprized at how much the paint sticks even after useing all that wax.In the end you can do a shellack wash to aged it or a grey dust age.
There is a crakel finish from mohawk paint that is called crakel laq but they say it's interior onlyAll the other brands I know of are interior.
The movie studios do a water based gloss bottom coat with a top coat of water based paint with sodium silicate added . We used it when we repaint and aged Ghost Town at Knott's Berry Farm but about a month after we finish we had one of the biggest rains in history.They called to say all the paint on one side of the building had slid down the wall and was on the ground.So I don't recommend that one outside.
Hope that helpes and call me if you you need any help.
