    My first ry at salt printing has ended with a streaked blotchy mess. As near as I can tell I didn't get an adequate coating of the salt compound i.e. there is an overall image but some areas are a deep brown and loo good but the rest are a very weak milky tan. I assume is the milky tan is just the sensitizer without the salt.
    I am using arches platine and applied the salt (ammonium chloride and sodium citrate)with an acrylic rod as I did the sensitizer and the coating looked even.
    I did however have a lot of trouble with trying to get it even. Should I switch to a brush for the salt? double coat one or both salt and sensitizer? Put extra sizing on the paper?

    You may need a surfactant to assist in spreading the chemicals.

    I would suggest that you try the Richeson 9010 brush. It is the favorite brush of many people who hand coat with processes such as salted paper, vandyke, kallitype, and pt/pd. I find it much easier to get a good coat with the Richeson brush than with a rod, and especially for large prints.

    coating salt prints

    You might try coating with a wad of cotton. That's what we use (when we choose to coat by brushing v. floating). Like anything of these methods, it takes a little practice. Use large wad of cotton, make sure you soak the cotton well; brush in several directions to ensure you get rid of any puddles. Wait before drying to let it spread. Don't expect great results when you're first learning, this is technique-dependant.

    My husband, Mark has been using the same paper as you (Platine) and has good results with coating this way.

    I tried to attach one of his prints, but don't see it in the preview. (first time trying this... :surprised:). If you don't see it, you can email me and I'll send you a jpeg.
