Stripping – $54–$151/100 sq. ft.. “The principle of paint strippers is penetration of the paint film by the molecules of the active ingredient, causing its swelling; this volume increase causes internal strains, which, together with the weakening of the layer's adhesion to the underlying surface, leads to separation of the layer of the paint from the substrate.”— Wikipedia. All the stripper will do is soften the paint. You’ll still have to scrub or scrape it off.
If you have kids, pets, or occupants who will damage the walls, it is recommended to go with washable matte, eggshell, or satin, because these paints can be easily cleaned and are more durable. However, flat paint can be touched up more easily and hides imperfections better, so if you are selling the home, it is highly recommended to go with flat. Bathrooms with showers/tubs should go in semigloss- unless you are selling or want a specific design look, then use satin. Louisville House Painting
The primary difference between interior ($15 to $70 per gallon) and exterior paint ($25 to $60 per gallon) is the resin. The resins used in exterior paints are softer, making them resistant to flaking, chipping, and sun damage, whereas interior paint uses more rigid resin that resists marking and staining. Many exterior paints use a resin that causes outgassing, an emission of volatile organic compounds. Common to many manufactured products, it is what causes that “new car smell.” The outgassing from exterior paint resins can continue for many years, even after the odor dissipates. It is a major reason professionals don't use or allow homeowners to use exterior paints indoors.
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. House Painters Louisville
