I painting vinyl siding. I'm using Benjamin Moore products, Moorgard, and I have fresh start primers, oil and latex. I know it's clean, I did it by hand with sponges, brushes and rags by hand myself with tsp and properly rinsed. Squeeky clean when wet. The weather has been good, sunny dry here in northeast PA. The paint color is lighter than the original siding colors. The vinyl is a vertical type with a wood grain look and is about 15 years old.
My BM retailer recommended using latex 100% acrilyc primer so I primed and painted a dormer and 10 days later I can fairly easily scrape it off with a fingernail. When I asked about emulsabond they said that the primer is a bonding primer and I should not use a bonding additive. Over the last 10 days I have tried a number of paint primer configurations. including paint without primer, oil primer and using emulsabond with latex primer and using emulsabond with paint and no primer. Although the emulsabond test seem to do better than the others, it really changes the nature of the fingernail scrapings more than solving the bonding issue altogether.
It should be noted that Flood recommends against using Emulsabond for vinyl, and that none of the newer test spots are on more than a 7 days or so.
I have not painted vinyl before so I really do not know what to expect.
Am I expecting too much?
Is it just a matter of cure time?
Is my vinyl different?
Should I use Sherwin Williams Duration?
Thanks, Rob
