How do I paint interior doors black?

Did you use latex? It sounds like it. Hopefully your primer was oil or your doors will begin to rust. Only use oil on metal. The best thing to do at this point is strip off the paint and redo. If you try sanding it will gum up the sand paper and start to peel. I'm so sorry you are having a bad time of it. The paint store should have advised you better.

Hi Kim. I'm Cindy. Have you talked to anyone from Sherwin Williams? Did you tell them what you intended to paint? That's where I would start. They would be able to advise you where to go from here. Good luck Kim.

Hello. Sounds like a nightmare. Have you contacted the customer support number on your paint can? When we have had paint failures and problems the support has been excellent even to the point of shipping us replacement product. It might be a good place to start.

Honestly, it is hard to get a good finish, especially if the door is still hanging, because you are working against gravity. Throw in a metal door with imperfections, and it is even more frustrating. Check with the company as the others suggested, because it may be the paint and the gloss level. If you have to repaint them I would suggest paint intended for metal like Rustoleum. Also, if you have access to a paint sprayer, you will usually get a smoother finish. If the door can be put on sawhorses to paint, it will make your life easier! Good luck and stay safe!

For metal doors you need to use DTM paint (direct to metal). Sherman Williams sells it. Nursing home I worked at had metal doors and we only used DTM paint. Metal expands and contracts differently than wood with temp changes. You will need to scuff up the surface to remove any shine.

Ahh that sounds awful. If there is any way you can strip it all. I have heard of applying stripper and adding plastic wrap over night. I hear this is easier to redo a job. Geez sounds like a mess. How many doors are already complete? Sherwin Williams has great paint for specific applications. DTM by Sherwin Williams would be the better paint for your job. Also, Rustoleum paints. You might be able to order rustoleum in a can rather than a spray since you have a large area to paint. Good luck! I am so sorry you are dealing with this.

Using a semi-gloss will often yield odd results. You will need 3-4 coats to get it uniform. I would have gone with an enamel paint. You are stuck with same if you re paint but it's so durable with reliable finish every time.

I have been doing finish work for nearly 30 years and it took me a while to figure out how to get a smooth finish, but I had to before I could begin doing and selling work to customers. The ‘trick’ is to lightly sand between coats. This knocks off what are known as the ‘nibs’, small particles that settle in the paint while it’s still sticky. You are probably using enamel paint seeing as how you’re painting metal doors, and enamel dries very slowly. This means that nibs have a lot of time to settle in the paint. There are products you can buy to shorten drying time that you just add to the paint.

You don’t mention if you are an employee, or owner. If you’re an owner another option is to knock out the hinge pins and remove the door. Then paint it and lean it against a wall at about a 30° angle with the painted side down, and leave it until the paint dries. This will probably give you the best finish.

Curious why would you paint the trim the same color as the door? By trim you mean things like door handles?

I would buy Rustoleum. They have a nice black paint that can be put on with a roller, brush or sprayer. I am talking about a quart of paint, not the spray can.

You just need to do a couple of coats of paint

If absolutely no bare metal test an area with black emulsion paint. Good luck
