Paint can last a variety of times, with latex paint lasting an average of 10 years and oil-based paint up to 15 years. Used cans of paint go bad faster and may only last for one to two years. Oil-based or latex paint will last longer.
To store leftover paint, it is best to keep it in a dry place out of direct sunlight. Consumer Reports provides tips on when leftover paint is past its prime, how to dispose of it safely, and which interior paints are the top of their tests.
Unused latex and water-based acrylic paints can last up to 10 years, while alkyd and oil-based paints can last up to 15 years. The federal government estimates that over 750 million gallons of architectural paint go unused every year, equal to 10 of what’s sold.
All types of paint can go bad, but the difference lies in how long they typically last before they turn on you. An unopened can of latex or acrylic paint lasts up to 10 years, while oil-based or alkyd-based paints can last up to 15 years. New, never-opened cans of latex or oil paint usually last three years.
A general rule of thumb is to close the can within an hour or two after use and use the paint within a year. However, some paint jobs may last between 5-10 years, and potentially even longer if stored properly. It is best to keep paint cans away from direct sunlight and avoid harsh weather conditions, direct sunlight, or high humidity.

Old paint can be a sign of deterioration, with a harsh smell, physical changes, or separated solutions. If these signs are present, it is likely that the paint has expired. If the paint has separated into semi-transparent and opaque liquids, it is no longer suitable for use as the solvent and pigment won’t work together to stick to the wall.
To dispose of old paint, it is recommended to contact regional governments for programs to help people dispose of it, or donate it to building charities if it hasn’t expired yet. To avoid leaving leftover paint, it is recommended to contact local professionals like Five Star Painting, who can handle both inside and out painting projects and provide a thorough cleanup after the job.

A gallon of paint can cover about 400 square feet, which is typically enough for a bathroom or small bedroom. However, most rooms require more than one coat of paint, so a gallon can cover around 200 square feet if needed. Two gallons can cover two coats over roughly 800 square feet, which is commonly used for common-sized spaces like living rooms or larger bedrooms. To calculate the appropriate amount of paint, multiply the width and height of each wall in the space, calculate the square footage of each door, window, or wall cutout, and deduct this from the total square footage of walls, ceilings, and trim.
Rounding up is recommended, but if rounding up means purchasing an extra gallon when you need less than half, consider purchasing an extra quart instead. It’s important to have a little paint left over for touch-ups, but not to waste money on overbuying.

Hey this is Dave, now question is, how much paint do you need? This Regal select for instance, 400 to 450 square feet. Okay so …
Bad advice! There’s no such thing as a paint and primer in one. It’s a marketing, gimmick, Do yourself a favor and always prime and then paint. Primer is cheap at 25 bucks a gallon and can be tinted Then purchase a high-quality topcoat Trust me… I’ve painted a recently brand new painted walls with a paint and primer in one, and it did not take . I had to go back and prime the entire two-story home.
Paint and primer in one is a gimmick that was made up to be more competitive. It is always suggested to prime and then 2 coats of paint. Don’t believe me do one wall with primer and 2 coats and then do another wall with just 2 coats of paint. You will notice the difference. In fact Benjamin Moore suggests to prime and 2 coats. I would suggest Regal or Aura in the Ben Moore line over anything else.
I’m about to make my third trip to buy more paint for my room. I started out with 1/2 gallon of blue for my ceiling but needed a second and I started out with a gallon for my walls but need 1/2 gallon more. This room is 8 by 8 with a 10 ft. high ceiling. I wish I would have watched your article before I ever got started.
Actually, it’s easy. With a normal water based paint you will need about 1l/ 10 square meters. You will probably do it twice to level up the paint, so make it 1l/5 square meters (i do it in meters cuz i am european). So you measure your wall: lenght x hight = square meters. Lenght 4 meters x hight 2.5 meters = 10 square meters. So you need 2l to paint it twice. (don’t paint it once, unless it’s a mild color and your wall is prepped right). You will also need a primer, wich is also 1l/10 square meters. So for that wall you need 1l of primer and 2l of paint. Easy, ha? 🙂
Regal DOES need a primer, stop talking bull. If it was Aura, yes, you would paint without primer, but with Regal you put 1 coat of 181 super spec, then apply Regal. If you put Regal on a wall like that, it will come off. Dont listen to this guy, ALWAYS buy a primer, no matter what. People also use it with Aura too, it’s much safer. Primers are cheap, so you dont need to be too.
