I do not know how to spray. I do one coat of primer myself because I never think enough primer gets on the cabinets when it is sprayed on. Its been my understanding that too much primer is a better problem than not enough.
My tenant is a painter and he will come and spray the cabinets.
I was hoping to find if there was a difference between vinyl sealer and clear coat.
Hiya Sac...
Grant brought up the point that no one ever answered your q about vinyl sealer - you mentioned that you're using all water borne primers and finish - does this apply to the vinyl sealer and clear coat too?
Typically clear vinyl sealers are for use beneath hot solvent topcoats (not water-borne), such as solvent lacquers, some epoxies etc. They are sometimes used as "sandwich" type primers to protect a solvent sensitive coating from a hot solvent finish coat. If that's the case, it doesn't sound like your finish is a water-borne clear. If it is a water-borne clear, are you talking about a water-borne poly? ...or a water-borne lacquer (CAB lacquer)? In either case, a vinyl sealer wouldn't necessarily hurt anything, but is not water-borne, and is way over-kill for what you're trying to finish.
Now, to further confuse the issue - water-borne polys typically don't call for any type of sealer as there can be compatibility issues with those components that make a sealer a sealer...Plus, most (not all) wb polys are not really an easy product to spray - they can be, but the recommended method is usually brush app.
And if you're considering the CAB lacquer (water-borne), CAB's are not always the best recommendation for kitchen cabinets as they are not typically very resistant to oils and grease, and can soften from detergent cleanings (and in the method you've described, they really wouldn't need a sealer anyway).
Let us know what the clear vinyl sealer and clear coat actually is that you're considering - but with the information we currently have, I think I'd recommend the water-borne poly with no sealer, and brush applied as opposed to spray.
