Recently, I repainted my home. Pretty decent job except the paint on the door is peeling off (presumably after it got scratched by the edge of a mop). This happened yesterday, around 9 days after they'd finished painting.

However, how can it be so sensitive to such a small scratch? Is it normal? Did the contractor do less than he needed to? We agreed on two coats of paint. This is a Nippon Paint for wood surfaces. I'm worried that before I even properly move in the doors are getting scratched, it might get worse in the future.

Thanks!

PS: My current home has oil-based paint doors and they have lasted for 10+ years with no issues like this whatsoever.

Pretty obvious he didn’t sand down and wipe down the previous painted surface before painting.

The new paint will never stick this way

Is it double coated?

Also, any recourse that I have if he didn't sand down?

Gloss paint need time to completely dry and adhered to the base surface esp when it is indoor.

How long is that? This was after 9 days

Since part of the paint is peeled off, try to cut a small piece and see whether the paint is still 'wet'.

There is no fix time frame. It depends on workmanship and weather.

Oil based paint looks dry from outside but not inner surface.

The paint feels sticky. If I touch it, it sticks and peels off.

Does it matter that it was not sanded before painting? Rather, it was just painted over the previous colour. Does it affect the long lastingness, the time taken to dry, etc?

Sanding makes the adhesion better....it helps to remove the original oil base.

Gloss paint takes time to completely dry ...there is no fix time. Proper care when one is near the door when newly painted.

Once it is 100% dry, it should last.

Actually for me, prep work of the surface is of paramount importance (80%) and the actual act of brushing the paint is secondary (20%).

Dust, finger oils, sanding dust (sand old paint will give a smoother finish coz old paint probably have teardrops) removed by wiping down with mild soap and let it dry..then paint using brand new brush so no hair stuck into the new paint.

I usually paint on my own as I can say I'm rather fussy about the output

Another POV we didn't explore-

Did the painter thin the gloss paint too much? If that's not the case then it's also the weather. Lately has been cold thunderstorms so it may take awhile to fully cure on the inside. If everyday hot season like sauna then it should have cured by now. You can also try to keep the door open and use a slow table fan blowing at it to "help" it cure a bit faster.

At least a month or 2. The longer, the more it get hard and strong.

means your paint is dry to touch but not completely cured, oil based paint take longer time to dry, it can take 4-6 hours to become dry to touch and even longer for it to cured

try to ventilate the area of the door especially if it is toilet door and keep the humidity low to help with the curing process, and oil based paint gassing off a lot, until you no longer able to smell the 'new house' or the thinner smell then the curing process is consider complete

another possibility is that the base surface has moisture which caused the paint not able to stick well, painting without sanding and priming the surface can cause this issue as well
