The next step up is a semigloss finish, which has the level of reflectivity that makes an impression but can be challenging to apply. Semigloss paint provides great coverage and is easy to clean but is less forgiving when it comes to brushstrokes and overspray. The highest-end finish is full gloss, which looks very luxurious when the job is finished, but requires a surprising amount of prep work and painting experience to apply correctly. It is also on the expensive side, so it is often used sparingly on door frames, window treatments and accent walls.
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.
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.
Similar to exterior mold, mold is more likely to emerge in warm and humid areas. That being said, rooms like bathrooms and basements are more prone to mold. To preemptively prevent mold, use paints that are mold resistant. Should you find mold on a wall in your home, you can clean it with a simple solution of one part bleach to four parts water. If the area is large, you may want to leave the cleaning to a professional.
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.
