Some small questions of the following: please check.
What is the best primer for wood doors?
Primer hides slight imperfections or old finish while providing a smooth, clean surface for the new paint. Wood doors need an oil-based primer and paint because standard water-based latex paints can cause the wood grain to rise.
What color trim goes with Brown Siding？
Beyond LRV, choose a color that complements the color of the door trim and the siding of your home. For example, a light taupe door would pair well with white trim and brown siding.
What is exterior Primer?
Both dedicated exterior paint (used in addition to a separate primer, covered below) and exterior primer-and-paint-in-one products will do the job. Today’s primer-and-paint combination formulas often cost half as much as separate primer and paint and provide equally good coverage in some scenarios.
