I am posting this message in both the s-i-l-v-e-r, silver fire and the Maxxmudd because the straining for these paint mixtues all have one main agenda, getting the paint to strain through the sock strainer at a rate equal to your pour in rate, with only a little back up. but the paint mixture i am using for this whole post is the one I'm using now, s-i-l-v-e-r. Hopefully this well aid others into not having all the problem,s i gathered on me, due to water amounts.
I CAN"T BELIEVE IT!!! All my problems with spraying s-i-l-v-e-r came down to one thing VISCOSITY. But not in how thin it was but how thick the mixture was. When i did the original s-i-l-v-e-r i added to much water to it from tipping my gallon can of mixed s-i-l-v-e-r to much while straining thus making me add more water to make sure the mix didn't back up. After that the mixture was still spitting and all i could think was "add more water, the mixture is still to thick"...Well..after talking with MississippiMan i began to think the whole s-i-l-v-e-r batch i made up still had to much water and maybe...just maybe having to much water was the issue. From that thought i went and bought a quart of Behr Faux glaze and added 2 oz of silver metallic plus the 4 oz of water that would be needed for making a quart of s-i-l-v-e-r plus and extra 1 oz of water for safe meassure. I hooked it up to my graco gun and sprayed. The mix sprayed out WONDERFUL, minus a few spit marks. But, these spit marks were diff then the spit marks from the super diluted, previous mix, so I added about 1 more oz and BAM!! the mixture exited the gun and gave a pattern that it was supposed to. Any other previous time, like if i was spraying some Kiltz primer or some kind of behr paint if i wanted a bigger and smoother spray i would add more water and that would help but not with s-i-l-v-e-r....Why does adding to much water with this formula or silver fire or any other ones make the gun spit more???
Just to give another visual add in. My super diluted, first batch of s-i-l-v-e-r, had a viscosity rating, according to the little visicosity cup that comes with the Graco Spray Station of 2 mins and 20 sec( I know we don't use the viscosity cup to determine the proper viscosity of s-i-l-v-e-r, just wanted a added visual). My new batch with the right amount of water had a viscosity rating over 5 MINS!! I can clearly see now why you don't use the viscosity cup to check for correct viscosity of the paint mixtures offered here. I have the Graco 3900 and the recommended viscosity rating, according to Graco is 190 seconds and they would say to me " you can't spray a mixture out of the 3900 with a viscosity rating over 5 mins....
With this knowledge i now know what happened to my Silver Fire i did last year. TO MUCH WATER!!! It's so cool to know my problem wasn't with a bad spraystation but with human operating error.......I guess that means i was problem, lol. I want everyone to make sure you don't add to much water to your mix, especially when you are using the graco 3900 system. If you have any doubts about things then ask. Second...THIS IS A BIG ONE...Make sure you keep a record of how much water you are adding to your mix. That will help other on this forums diagnose your problem better if you run into a spitting problem like i did....Again, KEEP RECORD of how much water you added to your mixture. I Didn't and now i realize that if i would have, MississippiMan or others would have realized my problem in a jip. Third...THIS IS THE BIGGEST ONE...watch how much you are tipping your gallon can of paint mixture when straining into the paint gun container. If you tilt it to much then more paint will back up into the strainer and you will add to much water to help it flow through the strainer at the speed your are pouring it into the paint gun container . I'll post some video's and pictures to go in more detail on proper straining, when it comes to the angle you tip your can in couple of days.
