DIY Exterior house painting?

Question:How to paint the house exterior

Answers:
Pressure wash and scrape/sand/brush any loose paint.

Seal surface with a sealer designed to prime and seal chalked surfaces.

Paint from top to bottom.

These are just high level rules of thumb. Factors such as condition of existing paint, material (wood, siding, stucco, etc), location all play a part in determining the right solution.

Best bet is to either clarify your question here with details that include the state, near salt or fresh water or no water, condition of the existing paint, the type of material the house is made of, etc. Or, take this information and an open mind to a local paint store. Cheap paint does not equate to a low cost job. Often times, cheap paint requires more coats than quality paint to cover the same area. You usually save time and money by buying as good a quality as you can afford.
