Remove any outlet covers or lighting fixtures (if possible). Then scrutinize the walls for any defects. Simply fill them in with caulk or spackling compound if you encounter cracks, dents, or holes in your walls and trims. There are also tips and tricks for filling nail holes. Once done with the repair, smoothen the wall down with sandpaper and then wipe it with a damp sponge.

After you have done the multiplication, subtract about 40 sq feet per window, and about 60 sq feet per door. Divide by 400 (interior paint covers 400 sq feet per gallon). The number that remains, is how many gallons you will need. If doing multiple wall colors, then you should do this process for each room (or sets of rooms) with a particular color. 
Your contractor will sweep or scrub the concrete first with a dry brush, and then clean it thoroughly with trisodium phosphate (TSP) and warm water, then let it dry. TSP is a mostly alkaline solution that does a great job cleaning grease and oil off concrete surfaces. Brush painting concrete siding costs $138 per 100 sq. ft., roll painting costs $50 per 100 sq. ft., and spray painting $32 per 100 sq. ft.
Repainting is key to maintaining exterior house paint. The material that your home is made of affects how often you should repaint. For instance, wood-paneled homes need to be repainted twice as often as those made of stucco. Environmental factors also play a role in how often you should repaint, since harsh climates can be hard on a home. As a general rule of thumb, homeowners should repaint their home every six to ten years.
Decorating a house is a fun but important activity. It is important to make sure the curtains match the walls and the walls match the furniture. Earlier, all interior walls were painted in the same color, and in the same way. Today however, we get to have more fun with colors and textures. It's possible to create a fun effect on your walls using a sponge or even crushed tissue. You may want to paint one wall a different color from the rest of the room. You get to decide what colors you want to use, and how you want them to look on your wall. If you really want to decorate your entire home by yourself, you can even try painting your house by yourself with these 5 easy steps.
Interview past clients. Talking to former customers is always a good idea. But, to ensure you're getting honest feedback — not just feedback from people who have been handpicked by the painter to sing their praises — ask to speak to the painter's three most recent clients. When you speak to them, ask about specifics. Find out whether the painters showed up on time, protected furniture from paint spills, kept the house clean, completed the project on schedule, and of course, what it cost to paint their house.
Get estimates from several contractors, request and contact references, search for complaints at the Better Business Bureau[12] and check that the company is properly bonded and insured, as well as licensed in your state[13] . Only pay a small deposit, and don't pay the entire amount until the job is finished to your complete satisfaction (both painting and cleanup).
For trim and doors, start with 1 gallon (3.8 L) of trim paint for every 600 sq feet of floor space. Purchase more at the store if/when needed. Trim is something that is difficult to calculate exactly, and it is more time-efficient to simply start with less than you need, and go buy more after you have used up the first round of paint and determined how much you will need to finish by seeing how much you have painted so far, compared to the gallons used.
Use semi gloss for hallways because walls there are more likely to be touched, bumped or otherwise marked over time (semi gloss cleans more easily). However, use flat for a living room. Flat will help hide imperfections in the walls. If you want the same color in both the hall and living room, then no problem. Use flat in the living room, semi gloss in the hall, making the threshold the transition point.
Staining a deck costs $540 to $1,000. Covered porches might hit $2,000. Consider negotiating the price a bit lower by combining it with a full exterior job. Painting handrails can run anywhere from $1 to $2 per linear foot, depending on whether it’s wood, metal or some other material. Although you might think this is an easy $30 to $100 job, most painters charge a minimum fee regardless of the size of the project. You’ll probably end up paying at least $150.
