Non-toxic finish for external use

[petersemple]

I am about to make some cages for the guinea pigs. Can anyone suggest a good finish to use outdoors that won't kill the animals if they gnaw on it? I know that shellac is non-toxic. How does it go as an exterior finish?

Thanks

Peter

funny, must be the season, I made one a couple of weeks back and used
Dulux Aquanamel. http://www.duspec.com.au/duspec/file/AUDD1282.pdf
lead free, non-toxic when dry

Try "Pure" Tung oil. Not the prorietary blends which are toxic. Might need maintenance coats from time to time. But still it's only a guinea pig house. I don't imagine an architect designed it.

[timdavis@activ8]

Non toxic actually means contains less than 20% solvents {which are very toxic)

Use Cabot's External Clear Gloss.
Its inert once properly dry as are most solvent paints

[timdavis@activ8]

Yeah, it's inert unless you eat it. Contains isocyanates. Every bit as nasty as it sounds.
