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.
Paper drop cloths: $3 to $5 for 9x12-feet. Paper drop cloths provide a cheap way to cover furniture or windows while painting small, indoor jobs, such as touching up window trim. They're absorbent and textured to hold paint. When you're finished, you can just fold them up and throw them away. However, paper cloths are not the best option for protecting floors since they can tear easily.
Determine the coverage area for each color and estimate the number of gallons you'll need for each. For odd walls with angled ceilings, make your best guess. If you're not comfortable doing this, measure the wall at its highest height and multiply that by its width. Now subtract the lowest height from the highest height, multiply that number by the width, cut that answer in half, and finally subtract that new number from the original height by width. That should give you the wall area.
Flat, or matte finish on the no-shine end of the finish spectrum. A friend to walls that have something to hide, flat or matte paint (the terms are interchangeable) soaks up — rather than reflects — light, has the most pigment, and provides the most coverage. It's good for adults' bedrooms and other interior rooms that won't be roughed up by kids. That's because it's tough to clean without taking paint off.
An example of the wall measurement would be: 40 linear feet of bedroom space, x 8 wall height, = 320, x 2 = 640. Minus 1 door (60) and 2 windows (80) = 500 sq feet being painted. Then divide the 500 by 400 (sq feet per gallon), and you get 1.25 gallons (4.73 L) needed for that room. For this, you'd need 1 gallon (3.8 L) and 1 US-quart (950 ml). If the amount it comes out to is over 1.3, we recommend just getting 2 gallons (7.6 L) so that you have leftovers if needed, since 2 US quarts (2,000 ml) costs essentially the same as a gallon in most stores.

A single gallon of paint can run anywhere from $20 to $80 per gallon. Professionals get a contractor discount of anywhere from 25 to 50 percent. For rough siding, like stucco, you’ll need to use 10% to 20% more paint. Some textures, like wood and stucco, require extra paint because they have more surface to cover in a tiny area compared to smooth siding. Use the highest quality exterior paint your budget will allow for your project. It will look the nicest and save you money by offering better coverage and durability. Better coverage means fewer coats and fewer work hours. You’ll also go a few years longer without needing to shell out more cash for a new coat. How do you know how much paint you're paying for? Here's some helpful math:
