Exterior Painting Services

Why Colorblast for your next Exterior Home or Commercial Painting Project?

A top notch Bay Area exterior painter, must be green minded and mindful of EPA and lead paint laws. Bay Area residents are not only environment conscious, but also pay some of the highest home prices in the US. Their Bay Area homes are high-end investment and they want to protect it with quality paint and sealers.

In some areas of the Bay Area (Berkeley and San Francisco for example), special care to paint color choices for detail work is needed to maintain the old Victorian look. It also takes extra masking time and in some cases, the careful touch of a skilled hand painter to get the details just right. The painting pro’s at Colorblast Painting have the knowledge and experience in these areas to ensure a great looking outcome that’s sure to impressed you and your neighbors.

Our 8 Step Exterior Painting Services Process is tailored to the Bay Area

1.Pressure Wash

  • The pressure washer is a loud gas powered machine (about as loud as a lawn mower)
  • The pressure washer will knock some of the failing paint off of the house. This will create paint debris around the house and most of this will be cleaned up on the first day. Any remaining paint debris will be cleaned upon job completion.
  • The pressure washer sprays a high powered stream of water at the house and water will enter the house through any open windows (or windows that do not seal well.) Please inform the Production manager and/or paint crew of any areas where water may enter the house.
  • TSP will be sprayed through the pressure washer to help kill and remove mildew where needed.
  • Pressure washing often leaves windows streaky so it is best to have the windows cleaned after the house is pressure washed (and painted) and not just prior. More on Power Washing


  • Scraping will be done to all areas where the paint is loose, and may take place on the first day or any day thereafter.
  • Scraping is designed to remove any failing paint (most of the scrapings will be cleaned up daily, and all will be cleaned up at the conclusion of the job.)
  • Small areas will need to be scraped again following the application of primer or paint because some paint will be pulled up from the surface following the application of paint or primer.


  • We will feather sand areas where the paint has failed and the material below is showing, unless otherwise clarified in the contract. Feather sanding is designed to reduce the visibility of the ridge that is created by thepaint failures. Sanding will not eliminate the paint ridge. It will only reduce the visibility of them.
  • Light sanding is done on glossy and certain other unpainted surfaces to create a “bite” on the surface for the latex paint to adhere to.


  • We prime all areas where there is a bare surface (wood, metal, etc) with a high quality exterior primer. This protects the surface and gives the paint something to bond to.


  • The caulk that we use is a top of the line product. It is an Elastomeric, water-based material. As caulking material dries, it will shrink about 30% . It is designed to seal cracks that are not larger than 1/8 inch.
  • We caulk all areas around the home that were previously caulked. These areas include window and door trim (where trim pieces come together)
  • Most wood sidings are not designed to be caulked due to the amount that they shift and move. When they are caulked, the caulking often fails or pulls away from the wood siding. Therefore we do not caulk these areas.

6.Stucco Preparation

  • If there is loose or failing paint on stucco then this will be scraped or wire brushed.
  • Cracks that are smaller than _ inch, but larger than a hair line crack, will be caulked with an elastomeric caulking. This is textured to blend in with the stucco. However, such cracks may still be noticeable after the paint application. Hairline cracks will be left alone to be filled in by the paint, which will be sprayed on and back rolled in to minimize the appearance of these cracks.
  • Cracks that are larger than _ up to an _ inch can, and will, be filled with a stucco patch, as well as smaller holes.
  • Holes that are the size of a half dollar unless they are very shallow cannot be fixed using a stucco patch and must be fixed prior to our arrival, unless specified in the contract.


  • When spraying is necessary all windows will be masked. The masking used is a thin layer of opaque plastic sheeting that will be taped over the windows. The masking will remain over the windows from 1-3 days while spraying is being done around the house.
  • Other areas that will be masked around the house include the ground, roof line, and other areas that are not to be painted.
  • Trees, plants and shrubs around the house will also be covered up. However, if they are touching the house or if they are very large they may get some paint on them.
  • Some small plants or flowers may get flattened due to the covering that is used.
  • In order to work around the house we must be able to walk around the house. Plants that are close to the house may be unavoidably stepped on.


  • Our policy is to spray all areas that can be sprayed. On medium to thick stucco, and on some wooden surfaces, the area will be back-rolled as well to push the paint in and to give a more even and uniform finish.
  • All areas that cannot be sprayed will be rolled if possible.
  • All areas that cannot be rolled, or sprayed, will be paint brush applied.
  • Confirm with the Production Manager whether you are to receive one or two coats of paint.
  • With any color change, it is recommended that two coats are done to ensure that the color does not bleed through. Some really bright or really dark colors may need three coats of paint. If this is required, the production manager will outline the additional cost.
  • Only the highest quality paints will be used.
