Trouble Painting Laminate Counter Top

I need some help. I painted my countertops with granite spray and used a water based poly on top (4 coats). That was 3 days ago. They feel dry to the touch, but are soft enough to leave marks.

What can I do to fix this problem? There is also a few milky streaks when you look just right in the light. Anyone know why? I waited the 2 hours in between that it suggested. Any advice would be greatly appreciated.

I painted my laminate countertops. I did my 14 foot long countertops and they came out good. I started doing my 4 foot counter and disaster hit. I believe i did the same technique as the other countertops. I sand then apply the minwax polycrylic and it keeps crackling. I let it dry for 24 hours then sand down again and the same thing happens when I apply another coat. I have repeated these steps 4 times already.

I believe the coats of clear coat were not fully dry because there was very hot and humid weather even though to the touch it was dry. My question is should I leave the countertop alone for about a week then sand it down then apply the polycrylic or should I sand it down now then wait a week to apply the polycrylic? I'm figuring maybe I could give it some time for the under coats to get hard.

Please help!

If your granite spray is an oil-based paint, that could be the problem. Putting a water-based paint over an oil-based paint can cause bubbling and peeling. If your paint store has knowledgeable employees, they might know how to solve your problem.

For future reference, when painting standard counter tops you should use a product specifically for that purpose. Here's a link to a DIYer that used Rustoleum's counter top paint:

I have no advice on the current problem though.
