Discovering what it cost to paint the interior of a home can be a little tricky. It all depends on several key factors: the type of paints, the amount of prep needed, how many coats, how large the space is and the amount of protection needed to non painted surfaces and areas. We have painted a bedroom that can take just a few short hours and cost $300 or so dollars on one home and then spend over a week painting a bedroom with two painters and cost over $5,000.
I am not one to typically write reviews but I was so happy with the work that Warline Painting had done, they completely exceeded my expectations. Heidi helped us so much with all the decisions that go with an exterior renovation to ensure that everything came together and it looks AMAZING. I have had many paint jobs over the years inside and out and by far this is the best. The painters were meticulous, polite and the clean up everyday gave the kids back their space.
It pays to be proactive regarding home improvement projects. If you can tackle multiple tasks at once, you end up saving both time & money in the long run. So, before you call the job done, make it a point to inspect your baseboards & molding to see if its time for them to be replaced. Doing this before you tackle the paint on the wall will save you headaches later on & will only add to the facelift you’ve given your home interior.
Back to the article. You can add water to all latex based paints / thinner to oil based paint. The tinting base has absolutely nothing to do with it. Say you are working outside and throughout the day you have to add a little water to keep the same consistency. If somebody really tried to add 20% to 50% water they no longer would be painting they'd be performing a whitewash or pickle finish.

To get basic measurements, measure the length and width of each wall you want to paint in inches. Multiply the length and height together, and divide by 144. This will give you the square footage for each wall. A gallon of paint typically covers around 400 square feet. In some cases, you may need a primer 2 first, then a single coat of paint, meaning that you may need one gallon of primer and one gallon of paint to cover 400 square feet. However, if the wall requires multiple coats, this will increase the total amount of square footage required, and therefore the amount of paint.
The graph says the average cost to paint a home interior is $1600; at the high end, $4,000. But for what size home? I'm getting estimates for painting an 1800 square foot townhome in the range of about $6500 - which includes sanding and repainting all doors, and painting all trim, walls and ceilings. What does the range above include and for how big of a home? Thanks.
