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.
Prime. Dark colors, stains (once sealed), and previously unpainted surfaces (drywall, spackle, etc.) will need a primer coat, usually white. NOTE: most paint stores & home improvement centers will now tint primer (at no charge) to match fairly close to the color of the finished coat, that way two coats of primer need not be applied.[6] Although not all surfaces need a prime coat, skip this step at your peril! Dark colors will likely show through the first -- or even the first couple-- topcoats of paint. Sealants and unpainted surfaces like spackle patches will absorb or repel moisture in a topcoat at a different level than the areas surrounding them. Applying a good primer coat will help even out these differences. Primer equalizes a wall to a uniform surface. It's like erasing a canvas before drawing a new picture. Although some will argue the point, you generally don't need to spend a great deal on primer or buy special primer. A cheap, 5 gallon (18.9 L) bucket of plain, flat white paint will usually do the trick and cover a large area. Give your primer at least 24 hours to dry (follow its instructions) before applying a topcoat.
The following guidelines will set you up for success. First, start at the top and work down. Second, paint out of the sun’s glare, since the sun will cause the paint to dry too quickly and flake or blister. To avoid marks, try to brush from one wet surface onto another. If you do have to paint onto a dry surface, overlap the wet paint onto the dry surface by several inches.
If you are painting for a client, skip the paint in the bucket, and use large trays. For faster completion and still quality results the 5 gallon bucket and strainer work great as well as a wood filler, 5-in-1 tool, screw gun (drill), metal joint compound tray, metal putty knife, wide drywall knife, mini hand-held paint containers (for brushes), and a mini-roller and corresponding nap (for edging, after cutting in with brush on the bottom, top and sides of wall, and the sides of ceilings, so that you don't see brush lines).

One of the most common home-improvement projects can also be one of the most enjoyable for the entire household. While some aspects of interior room painting, such as masking and “cutting in,” can require some experience and skill, applying a fresh coat of paint to a ceiling or wall or doorway is often a matter of a good brush, a paint tray, and some sweat equity. A coat of fresh paint may be all that’s required to revive a living space that’s faded a bit.
Paint supplies cost anywhere from $10 to $100 or more depending on what you need. Painters will typically provide most of the supplies for a project, but sometimes they will allow you to pay for solely labor if you provide all the materials yourself. You might decide to do a DIY paint job down the road. In which case having these supplies on-hand will save you time and money.

There are a few ways to prevent your interior house paint from fading — or stop it from getting worse. One simple fix is to install shades or curtains to block incoming sunlight. If you don’t want to shut out the light, you can also tint your windows with a UV protectant. However, fading shouldn’t be much of an issue if you use high-quality interior house paint.

One of the first considerations when it comes to interior house paint is the base. There are two schools of thought, each with their pros and cons. Some brands commonly sold to contractors for commercial projects are oil-based, meaning the chosen pigment is mixed with an oil derivative called alkyd. Oil-based paint provides thorough coverage, and the finished coat resists moisture well. However, oil-based paint releases a high level of volatile organic compounds (VOCs) as it dries, and it can only be removed from floors, brushes, and clothing with strong chemical paint thinners. In fact, many states have actually banned the use of oil-based paints because of their VOC levels and hazardous ingredients.
Latex paint refers to water-based paint, the most popular and environmentally friendly paint. Since latex paints provide great color retention, they’re ideal for exterior walls that face a lot of weathering. Latex paints are also a good option for interior walls that are subjected to a lot of moisture, such as bathrooms and laundry rooms. Additionally, latex paints dry faster than oil-based alternatives and produce fewer odors.
Most of a projects price is the cost of labor at $25 to $75 per hour. However, most contractors bid out based on the entire project which includes all work hours. Hourly rates are only useful if your pro asks to do the job as “time and materials.” However, be wary of this pricing structure, it usually shows the contractor is uncertain how long the project will take.
