Oh, where to begin? Let me start with 'watered down paint'. 25-50% before the material gets to the site? Impossible. You would basically be painting with water at that point. It would be less of a hassle, and cost, to simply use proper material. You would be forced to apply three coats instead of two, as the coverage would be horrible. Whatever cost you think might be saved in materials would be lost in labor.
I would not recommend this company for the following reasons:1. Original appointment was very specific to them on what was needed and to take photos for 3 apartment unit plumbing fixture repairs. One unit had a bathroom tub/shower backup.2. No photos taken, 3 trips later and only 1 unit completed to satisfaction. (Backup) 3. Other faucets unable to find on line with their suppliers and repair 4. Had to find another plumbing company to complete the jobs. 5. Invoicing had to be redone as not in detail of job address for tax purposes 6. Bad communication throughout the project process with their internal customer service. Their technician and project manager ordering parts. 7. For the back up. Did not bring out correct snake on both trips and had to replace lines as too small to break through backup. Costing over $800 for 3 trips just to complete that situation out. 8. Ordered the wrong parts when 2nd trip out since no photos taken to confirm what was needed. Very dissatisfied and will never ask them to work in any of our rental properties again.
To begin, move everything out of the room. Every painter we spoke with had a horror story about the time he didn't follow Rule No. 1. Bigger pieces of furniture can sometimes be left covered in the center of larger rooms, but if you are repairing drywall, says Chris Span, of Span's Quality Painting in Mobile, Alabama, "Take everything out. Drywall dust goes everywhere." Remove doors, light fixtures and hardware, and label everything with masking tape. Also, invest in drop cloths. "It's surprising how well a few drops of paint can cover a floor," says Rich Maceyunas, of Maceyunas Painting and Wallpaper in Waterbury, Connecticut. Buy high-quality drop cloths, such as canvas or paper-backed plastic. (Paint soaks right through lightweight fabrics and bedsheets.) Plastic sheeting works, but it's very slippery and doesn't absorb drips.
With an exterior paint job, proper preparation before painting is essential for the paint to withstand the elements over time. Preparation may include sanding rough surfaces, patching holes, dents or cracks, caulking around windows, and priming all surfaces before painting. Proper preparation will have a big impact on the finished appearance and how long the paint will last.
Even if you go it alone, specialize to keep your initial investment low. If you do only interior painting, for example, you might get by with one ladder, a few brushes, rollers, basic hand tools and such, for an investment of less than $300. Again, you can add to your tools as you need to (every job is a bit different), and parlay profits into the equipment necessary for exterior painting or working on large commercial properties.
