Factors That Affect The Painting Time For A Room 

There are different factors that will help determine how long it takes to paint a room in your home. The more you can cut down on each of these, the easier it is to make the room look nice, and the less time or half the time it takes. Some of the factors that influence how long it takes to paint a room include: 


Before you start painting project, you will need to prepare the room. This includes moving items out of the room, covering up anything that has to stay, and cleaning the walls. Some choose to put painter's tape down to keep the edges clean. 

This can add to the overall time that it takes to keep the room looking nice. The more rooms you paint, the faster the preparation time will be, helping to speed up your painting time.  

Size of the Room 

The size of the room will determine how long it takes to paint. Smaller rooms have less area to paint over and can be done faster. If you have a really larger rooms, you can expect it will take longer to finish all of the painting and make it look nice. 

Smaller spaces are going to be easier to paint job and will not take as long. You can factor in the average sized room or average room length of time it takes to roll paint per square foot to help set an free estimate of cost and estimated time to get the work done.  

Previous Paint Color 

The previous color of the walls will make a difference on how long it takes to paint. The darker the color, the longer it will take. With dark paint, you may need to use a good primer and wait for it to dry before you can start with the new color. 

If the walls were a lighter color to start, you might only need to put one coat of paint on the walls to be done. Darker colors of chipped paint depends upon how many coats you apply. Generally darker colors will need to apply paint in two coats, and this takes longer.  

Weather Conditions 

The weather can slow down the drying process when you are done painting. Humid weather will slow down things and can mean you will need to wait longer between coats of paint. If the air is dryer, like in winter, you will be able to get the more paint to dry a little faster because there is not as much moisture in the air. 

If you are experiencing lots of humidity in your area, you may want to wait a few days before you start to paint a room. This can speed up the painting process.  

Tools and Equipment 

The tools you use will make a difference in how long it takes to paint. If you use traditional rollers, brushes, drop cloths or sanding sponge for excess paint soaks and the work will get done more slowly than with a paint sprayer. Most homeowners choose to use a roller and paint brush or angled brush because it costs less money, but they will take a little longer to get the work done. Homeowners also use extension rod for painting higher sections of open walls. 

Paint Color and Type 

The type of paint and the color of the paint will make a difference. Some paints are thicker than others, which helps you to cover the area faster than others. Darker and bold colors tend to stick on the wall a little better, helping you to have a great-looking wall in a fraction of the time.

Tips To Speed Up The Process 

Painting your home can seem like a huge task. It can take time and will waste up a whole day if you are not prepared and ready.

There are some simple steps you can take to help speed up the process and make sure that your painting walls look amazing when you are done. Some of the best tips for how to paint a room quickly include: 

  • Gather The Supplies
    Figure out what you will need to get the room painted and find them all before you start. If you have to stop and find more items throughout the painting job, it will slow down your progress. Bring all the items into the room with you. Have some extra paint brushes and excess paint on hand and rollers in case you need more than you thought your paint job. 
  • Prepare The Room
    Efficient painting needs some efficient prepping. You will need to get the room ready so that you can get going. Clear out all the items with drop cloths, put down the painter's tape, and get to work to make the area look nice. Cover window frames and remove picture frames. This will speed up the process.  Remove painter's tape after finishing your painting process.
  • Prep The Walls
    Clean off the walls with drop cloths to remove some of the lint, dust, and debris that can gather there over time. You can even add a clean rag to a swivel duster and clean off the hard-to-reach places.
  • Skip The Painters Tape
    Taping the trim may seem like a good idea, but it can take a long time to do. If you are careful around the edges and use a good paintbrush, it is not necessary. If you plan to repaint the trim, too, there is no need to add the painter's tape to the area at all. 
  • Skip The Primer
    This will be a good shortcut because more rooms do not need it. The only time primer is necessary is when you are taking a darker color and turning it light. If you have a really dark and bold color on the wall, you may need to use the primer or painter's putty, but for most paints, you will be fine just painting over it. 
  • Start At The Ceiling
    Go from top to bottom. The ceiling is never fun, but if you get it out of the way from the beginning, you will be able to avoid some of the hassle of doing it later and reaching over wet paint. 
  • Roll, Then Cut In
    This helps you to make big progress quickly, which can trick you into thinking you have gotten a lot of work done in a short amount of time. This is the opposite of most advice, but it does work.
