Stacee, I agree with you completely, from adding water to latex paint to taking whites from job to job. This article makes all painters look like scam artists. You get what you pay for people! There is no denying that there are scammers out there but in my experience, most painters are under paid any ways so if you want a good paint job, you are going to pay for it. If you just want a new color on your walls real quick, and that is what you pay for then that's what you pay for people. Most painters get the crap end of the stick and are left with making an entire house look good when it took a lot more than a painter to build the house in the first place. Good painters do not get enough credit. They are not all scammers who are cutting corners!
With that said, here's the reality of that particular scenario. Painters do put water in the paint, but not for reasons you would think. Some materials need to have their viscosity manipulated in order to slow drying time, allowing gravity to 'smooth' out the product for a better finish. It also prevents 'drags' and 'sausages'. I personally try not to do it too often, but from time to time I have to. I want my client to have a proper finish.
Use a roller to paint the rest of the wall. A good method to use is the 'W method'. You start by painting a large 3 foot (0.91 m) square W on the wall. Then, without lifting the roller, you fill in the W. You can paint a wall section-by-section, and do the walls one at a time for best results. It's generally a good idea to use an extension pole for your roller instead of standing on a ladder. Make sure that neither the extension pole nor the roller has plastic handles, as plastic handles are flexible and this makes it difficult to control the painting.
When painting the trim, you don’t have to be neat. Just concentrate on getting a smooth finish on the wood. Don’t worry if the trim paint gets onto the walls. You’ll cover it later when painting the walls. Once the trim is completely painted and dry (at least 24 hours), tape it off (using an “easy release” painter’s tape), then paint the ceiling, then the walls.
Paint preparation is the foundation for the entire job — if done correctly your paint will perform to its fullest potential. If done incorrectly, the best paint will crack, peel, or chip easily. Make any necessary repairs before you start your painting project. Dirty walls should be cleaned, especially near the stove and sink. Greasy deposits and soap scum can interfere with paint's adhesion.

Thanks, all, for your time & efforts adding to the article & comments, especially Dave urging requesting both General Liability AND Worker Compensation insurance certificates to protect from real & fraudulent liability--from my experience especially in California, where insurance fraud is a popular income thief, even causing car collisions to collect.
We don’t believe in handing our customer a roll of tape and asking them to check for deficiencies. That’s our job and we take it seriously. Our quality control is ongoing and done through every step of the project. Our interior painters are constantly checking their own work and our team leaders conduct a full inspection of the job when it’s completed. Our layers of quality control and inspections mean that when we are done, and you do a final walk through, the only thing you should be seeing is a beautiful paint job.
You are right on with this - why do people leave switch plates on when it's just so easy to take them off? Another thing that happened to us - we had the popcorn ceiling taken off and the ceiling painted white. When the job was done and I later went to change out all the fixtures/fans, they had left every fixture in place, so there was a large patch of popcorn and unpainted ceiling left behind - it just didn't dawn on me to specify that they take those down before scraping and painting. It was kind of a mess.
We've heard countless stories of people who have been let down by other house painting services. No one wants to take valuable time off of work to wait for painters who never show up. At Handy, we pride ourselves on connecting our customers with reliable and trustworthy residential house painters. They will arrive on time, fully ready to do your job.
To paint a large section without leaving lap marks, roll the nearly dry roller in different directions along the dry edge, feathering out the paint as you go. After completing the entire length of the wall or ceiling, move to the next section and paint over the feathered edges. For the second coat, apply the paint in the opposite direction. This crisscrossing paint application sharply reduces (if not eliminates) lap marks.
If the point of hiring a well established, experienced, reputable painting contractor is to secure the professionalism and trust suggested to be inherent with that choice, then I would EXPECT that professionalism and experience to include the ability to make the proper and correct calculations for labor and materials for a fixed price quote, and there should be NO reason for the contractor to put the cost burden of their miscalculation on the consumer.
Yes the pricing does change, and quite significantly. I have worked inside the paint industry on counter sales outside sales and application for over 10 years. One thing many people do not understand is, the resins in the paint are more expensive to produce the higher the sheen goes. Therefore the company is at of higher cost making the paint, which in terms they charge more for the paint. I have seen a 15$ variance between flat-semi-gloss it is not uncommon and is not unrealistic to pay more for a higher sheen. Another thing to add is when doing samples on your wall prior to a painter coming is a good idea, however do not do them in huge squares with heavy coats, remember you are just wanting an idea. A lot of times the issue comes up of the paint not covering the sample coats, in fact it is covering quite well, however the paint sample applied is often times much darker than the wall color, creating a contrasting difference from the lighter surrounding wall and the sample placed on the wall. I recommend getting a piece of sheet rock and using it for the samples so you can move around with it etc.

These guys are first class. We are going to be building soon, and I will be using this company to do all interior and exterior paint. Heidi and Warren are fully involved from the start to the finish of the project and they are exceptionally helpful. These guys are all wonderful. They show up when they say they are going to show up. They are respectful on the worksite and everyone is friendly and hardworking. Thanks guys. Looking forward to working with you again soon!
Unless you like textured walls, don't paint over dust. Wash the walls with trisodium phosphate (TSP) or a mild cleaner, like Jasco's TSP No-Rinse Substitute. For smoke-stained walls, Toto uses a 50/50 solution of bleach and water. To clean a wall, use two buckets. Load up your rag or sponge from your cleaning-solution bucket, and scrub. Before redipping, rinse the sponge in a second bucket filled with clean water.
Plan the workforce. If you intend to not hire a professional crew, you'll need lots of help. There are many jobs to be done. First there's the furniture moving, then wall preparation, floor covering, materials gathering and prep, cleaning, and don't forget everyone will have to eat. It can easily take a team of five people a full ten days to paint a two-story (approx 2000 sq.ft.) home. Get as many people to help as you can. If some can only come one or two days, great. Maybe others can fill in. Ensure you plan with your workforce members in mind. They'll need plenty of time to arrange days away from work. Identify a few key personnel:
The speed with which a painter can complete the job will determine its final cost, but time is difficult to estimate. Some painters have more experience and cover a wall faster, but some are more methodical and take more time. Most painters should be able to cover about 100 to 120 square feet of flat surface in an hour, unless they are working on a very large wall. Wood or plaster might reduce that amount to 80 to 100 square feet. You should also consider the time required for a first coat to dry before a second coat may be applied. This will add time as well -- anywhere from one to 48 hours depending on the paint.
