Rob R. 14 Report post Posted July 14, 2010 Hey everyone, I recently bought a Graco 190ES sprayer to apply stain to fences and decks and it worked great for the first job using olympic semi transparent. I flushed it out with paint thinner then water as directed. Now I went to use the sprayer on another deck and it loses spraying pressure after about 10 seconds. Seems almost like its getting air in somewhere. I then have to price it then build up pressure again only for it to lose pressure after another 10 seconds. Any help is much appreciated.. Should I called the distributor I bought it from but not much help, can't seem to find where I placed the manual either and the Graco site has manuals but they won't load!!! Thanks in advance for any suggestions! Share this post Link to post Share on other sites
