Hello Everyone,
I sprayed a test panel with epoxy that I reduced 4:1:2, the two being the reducer as recommended on the tech sheet but it is still a little thicker than I'd like for use as a sealer prior to base. Is there anything wrong with adding more reducer such as 4:1:3? The product is Matrix Epoxy Primer.
Thanks advance for your advice ~ Lenny b

So far I sprayed it as regular Epoxy mixed 4:1:1 through a Devilbiss FLG4 Finishline with a 1.8 tip at 23 PSI. At that ratio it is thick. I then bumped the air pressure up to about 28 PSI and thinned to 4:1:2 and it sprayed a lot smoother, still with the 1.8. My plan for using it as a sealer is to mix it 4:1:2 or 3 and use a 1.3 tip and play with the air pressure to see what works. I plan to just practice on an old deck lid to see if I can get the results I want.
Also the tech sheet says to mix it 4:1:2 as a sealer with a 1.3 tip and 23 PSI. I'll start there and play with the air followed by reducing more if needed. Just don't no the effects of over reducing and how much reducer is to much. Last edited by Lenny B on Thu Jan 11, 2018 3:42 pm, edited 1 time in total.

lenny one of the most common problems is not using the right equipment, that 4:1:2 ratio is the correct ratio, if you find it not spraying well then you need to look at spray gun before thinking more reducer will solve a problem. once you start flooding your mix with reducer you no longer have the product you expect to have on your job.
