Tip size for epoxy mixed as sealer


Sorry if this has been asked before, I searched but could not find the answer.

I believe the TDS for epoxy primer says to use 1.4-1.5 tip size. I assume this is for unreduced epoxy.

I plan to spray my sealer using a Devilbiss FLG3. I have 1.3 and 1.5 tips...what size should I use for reduced epoxy?

How big of an area? I use a 1.4 LPH 400 for sealer. I think either would work, the 1.3 wide open on fluid, the 1.5 choked down to maybe 2 turns open from fully closed. Spray a test panel before spraying on the "real" thing.


Trying to be the best me, I can be
1.3 will give a slightly smaller pattern. Not as wet as the 1.5. The 1.5 will give a full wet pattern with epoxy reduced as a sealer. 1.3 will be easier to control and probably better suited for single panels. 1.5 will be faster but also easier to lose control of and get something too wet. Test and see what you are comfortable with.
