Priming the door with a product designed specifically for metal will keep your paint looking better for longer. Use a small paint roller to cover the door with two coats of primer, giving plenty of time for the primer to dry between coats.  Make sure the primer you are using is compatible with your chosen paint. Each product should say which others they are compatible with, but you can ask for help when purchasing them if you’re unsure. Different primers will take different amounts of time to dry in different climates. It can take between 1 and 3 hours for each coat to fully dry. Give the door a light touch every hour until you are certain the door is dry. If painting both sides of the door, you'll need to work one side at a time. Apply both coats of primer to the door and let fully dry before turning over to prime the other side. If you use a Direct-To-Metal paint, you can begin applying it without applying primer to the door first. Always follow the manufacturer's instructions when painting with a specific product. Make sure that you are using a paint that is designed for exterior use, such as an exterior satin or semi-gloss paint. Use a brush to carefully paint any grooves or panels on the door, before painting the rest with a small roller. This will minimize the brush stroke marks on your door when it is finished.  Be careful to fix any drips or uneven roller strokes before the paint dries. It might be easier to paint in the morning, early evening or in the shade, so the paint doesn’t dry too quickly and stays wet while you’re still painting.  Give the door plenty of time to dry between coats, normally between 6 to 12 hours but sometimes up to 18. Check the information on your chosen paint for more information on the expected drying times. Work one side at a time, as even slightly wet coats of paint can be damaged if they come in contact with another surface too quickly. Each coat of paint will improve the overall look of your door, as well as increasing its resistance to the elements. Give the first coat at least 6 hours to dry and then apply at least one more coat.   Follow the manufacturer’s instructions when applying paints. They will likely tell you how many coats you’ll need, as well as how long you should leave each coat to dry. If you’re unhappy with the look of the second coat of paint once it is dry, you can always add another one. Give your final coat of paint plenty of time to dry before putting it back in place. If the paint is still a little wet, it may rub off on the doorframe and need repainting. Leave it for as long as possible, but normally at least 12 hours. Heat guns and similar tools might help the paint dry faster, but won't dry it evenly and could even damage the paint if it is too intense. If you use something to accelerate the drying, do so carefully. Remove any painter’s tape you applied to the door when you began painting. Using a screwdriver, reattach any hardware you removed exactly as it was initially. Finally, put the door back on its hinges and reinsert the hinge pins with a hammer. You might want to remove the weather stripping around the edge of the doorframe for a day or two after reattaching the door. This will give the paint much longer to dry fully before the edges are pressed tightly against the stripping.
