What kind of primer should I use before painting?

The primer you use depends on the surface and the type of paint you'll be using. If you're painting over a previously painted surface, you can often get away with using a <a href="https://www.homedepot.com/b/Paint-Primers/Universal/N-5yc1vZbt0tZ1z0ut90?emt=plpfaq_2408_primers" style="text-decoration: underline;">general-purpose primer</a>. However, if you're painting over a bare surface, you may need a primer specifically designed for that surface.

Should I use a brush or a sprayer to apply primer?

How do I choose the right sheen for my primer?

The sheen of your primer will depend on the final look you're aiming for and the surface you're working with. <a href="https://www.homedepot.com/b/Paint-Primers/Flat/N-5yc1vZbt0tZ1z1vuja?emt=plpfaq_2408_primers" style="text-decoration: underline;">Flat</a> or matte primers are generally best for walls and ceilings, while <a href="https://www.homedepot.com/b/Paint-Primers/Semi-Gloss/N-5yc1vZbt0tZ1z10m17?emt=plpfaq_2408_primers" style="text-decoration: underline;">semi-gloss</a> or gloss primers are better for trim, doors, and areas that need to be cleaned more frequently. Always check the product label for recommendations on the appropriate sheen for your specific project.
