You can even cover your carpet with a canvas drop cloth. You can have a long runner of canvas cloth and put it down where you are painting.

If your floor is hard, you can use rosin paper as an alternative to canvas or plastic sheets. Both will be slippery for vinyl, wood, and tile flooring.

Cover all plates, switches and fixtures 

Remove all your cover plates or switches from the walls. It will make your painting work look more professional. Unscrew all the cover plates and cover all the outlets with masking tape.

You can do taping for an average room in 20 minutes.

Apply primer on your wall

Most DIYers avoid using primers; they want to skip this step.

They feel it will be double the work as the brush strokes and roller rolls are the same as a paint coat. 

If you have patched your walls with spackle or putty, it’s a good idea to prime the walls.

Your room walls might have stains, so if you plan to apply paint directly over them, it will take more color as we also have to cover stains.

It will also be cost-effective since primer is less expensive than paint.

A better primer will give a smooth and clean base to your room, and the final look of your paint will be professional.

When you bring your primer, first stir it from the bottom and then use it as it has been lying in the store for a long time.

You have to put some primer in the paint tray and use an angled paint brush to apply it to the edges of the wall.

Once you have applied the edges, you can now switch to a paint roller and paint the rest of the wall.

The drying time for the primer is one to four hours on average. However, it depends on the type of primer, room temperature, and humidity in the room.

Nowadays, primer gets dry within 30 minutes and you can add a coat of paint over it.

If you touch the wall after applying primer, you will feel it has not come off. Then it is ready for applying the first coat of paint or second coat of primer.
