Here's the story guys

>painting kitchen cabinets and drawers over weekend
>cabinets are some laminate or melamine plastic pink shit
>not very glossy or smooth at all
>sand every surface a once over with 600grit paper
>wipe with warm water to remove dust
>wipe a decent coat of ESP all over
>have used ESP before and paint turned out fine without priming
>wait 2 hours
>no primer
>paint 3 coats of semi gloss on
>it's been 2 days and the paint scratches off easily
>no peeling or cracking
>thinking of spraying a clear gloss coat all over to protect from scratches

Is the scratch problem because the paint has not cured yet, or is it because the paint has bonded poorly to the cabinets?

Due to there being no flaking, I'm hoping I can get away with a protective clear coat and not have to sand back to the plastic and start again.

Thoughts and advice would be appreciated because my missus is really up my ass about this one.

And when I say scratches off easily, I mean I can dig my nail in and leave a knick in the paint, revealing the cabinets original surface. Not scratching and chips of paint fly off.

-The cabinet material doesn't have a good bond to the paint.

-The paint you purchased is latex/ not for the purpose you used it for.

-Three coats if not allowed adequate dry time in between will take longer to dry. There is no wood underneath to absorb the moisture so all has to come through the top.

Pick one or a combination.

So a gloss coat over the top would not help to protect against scratches?

I'm happy to re do the whole job but if I can get away with a gloss coat and prolong the life of the the current job for a couple years even better

YOU DUN GOOFED.
Sand over everything and start again, prime then paint. Do not ever paint a second coat of semigloss or any gloss over another coat of gloss without sanding first, all you're doing is trying to bond a smooth surface to another one. ALWAYS wait for dry time before re-coat otherwise you fucked up. ALWAYS paint in the temp range and ALWAYS prime unless it's a 2 in 1 (which may or may not work).

If you want long life then get strong paint. Use a oil based paint if you want more durability, Rustoleum makes some strong shit. Then ENAMEL coat it if you desire more strength, durability and easier touch up.

also oil based is better for chemical resistance and water. Be sure to get primer specifically for oil based paint.

Considering its usually 150-300 that gets used for surface prep, no, no it's not.

Yeah if you're staining something.

Not this guy>>1185114, but as a cabinetmaker for over 25 years now, I generally went no higher than 180 grit for stain grade hardwoods...and thats about as fine as you should have too...600 is way to fine, scratches won't be deep enough...

I think you are fucked, you need to scrape the paint and try again
