Once the right primer has been purchased, feel free to prime your drywall. Lastly, after 2-3 hours, you can safely paint your drywall.

The general rule of thumb is to properly tape and mud drywall joints before painting. Not only will skipping this step lead to unattractive walls, but it is also against building codes. So yes, mudding the drywall before applying the first coat of paint is a necessary step.

Drywall and skim coats are highly absorbent and will require multiple layers of paint. It is better to apply one to two coats of a quality primer and seal the pores in those substrates before your top coat.

Matte, eggshell, and satin finishes are commonly used for painting drywall. Matte finishes have a flat appearance and are ideal for hiding surface imperfections. Eggshell finishes have a slight sheen and provide better washability. Satin finishes offer a subtle shine and are durable enough for high-traffic areas.
