Pros prefer 5-gallon buckets with a roller grid to roller pans. They hold more paint than pans and, says Doherty, "It's tougher to tip over a bucket." A bucket also lets you box, or mix, two or three cans of paint to avoid color discrepancies. To use a bucket and grid, dip the roller a quarter of the way into the paint and run it over the ramp to work the paint into the nap.
Sanding not only feathers out chipped paint but also provides "tooth" for the next coat of paint. For glossy trim, use a sanding sponge rather than sandpaper. Sponges mold to the shape of the trim and last longer than paper. When applying latex over alkyd paint or when he is not sure of the original finish, Brian Doherty, a painter in Richmond, Virginia, follows the hand-sanding with liquid sandpaper to make sure the surface is completely deglossed to prevent incompatibility problems. "I've seen homes where latex was used on oil-painted trim, and the paint started to peel in less than a year," says Doherty.
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.
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 budget. Costs will vary greatly, depending on price and quality. Choosing mid to upper-grade paint, expect to pay in the area of $350.00 in paint alone for a 2000 sq. ft. house. Add another $100 to $200 in brushes, rollers, pans, tape, and other materials. Don't forget food, if you plan to feed your workforce. When it comes to materials, not all paints are equal. Some truly cover with one coat, some say they do but don't. Your costs will double if you have to apply two coats to everything, so buying the cheaper paint might cost more in the long run. Trust your paint professional salesman (to a certain degree) to tell you which paint to buy. You can generally go cheap on primer, expensive on top coats.
My painter franchisee, who I got from Angie's List, must have found some shmucks on the corner to paint my house. I specifically said I wanted stain. First my house was painted the wrong color, Then it was painted with LATEX paint- not stain. Estimates to 'undo' the damage is around $10,000 and its not a guarantee that it will work. The work is at best amateurish. Many underpainted or not painted spots, drips, etc. They did the entire outside (scraping?, priming? caulking?, painting), cleaned up and left within the time I left for work and came home. There were thee of them (my neighbor told me) This was two years ago and I am still upset. Can't be fixed.
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.
