Exterior Painting

An Exterior Near the Ocean Is a Timing Job as Much as a Painting Job

Two crews can use the same product on the same house and get results five years apart in lifespan. The difference is rarely the paint. It is whether the surface was clean, whether it was dry, whether the temperature and the dew point allowed the coating to form a proper film, and whether the trim and the ironwork got the material they actually needed.

On a coastal block those variables are tighter than they are inland, and we plan the job around them instead of hoping.

Washing, and Then Waiting

Everything starts with getting the wall clean. Coastal exteriors carry salt, road film, and on shaded elevations a layer of biological growth that looks like dirt and is not. Salt left on the surface interferes with adhesion. Growth left on the surface comes back through the new coating.

So the wall gets washed appropriately for what is on it, at a pressure that cleans stucco rather than eroding the finish coat, and then it gets time. A cement plaster wall that has been soaked holds water for longer than a dry morning suggests. Coating it while it is still giving that water back is how you get blisters in the first summer.

Dew Point, Surface Temperature and the Marine Layer

Coatings have a working window. Surface temperature has to be above the manufacturer’s minimum and comfortably above the dew point, or moisture condenses on the wall as the film is forming and the film never properly coalesces.

In Santa Monica that window is narrower than most homeowners expect. On a typical late spring morning the fog sits until the middle of the morning and the wall is measurably damp. By late afternoon the temperature drops back toward the dew point again. That gives a usable stretch in the middle of the day, and it is the reason an exterior that takes four days in the valley takes five or six here. We would rather tell you that at the estimate than explain it later.

Trim, Doors and Windows

The trim on a Spanish Colonial house is where the sheen ladder matters. Flat hides surface imperfection and holds dirt. Eggshell and satin are the usual compromise on siding elements and shutters. Semi gloss and gloss give you a hard, washable film on doors and casings and they show every ripple underneath, so they demand more prep.

On doors and high wear trim the choice between a waterborne enamel and a traditional alkyd is a real one. Alkyd levels beautifully and cures hard, and it yellows over time and takes far longer to reach full cure. Modern waterborne enamels have closed most of that gap and stay truer in color, which matters on a white casing in strong sun. We pick per element rather than per job.

Windows get their glazing checked before anything else. Loose putty on an older wood sash is a water entry point, and painting over it just hides the gap.

Wrought Iron and Metal

Gates, window grilles, railings and stair rails are standard here and they rust here faster than they do inland. Painting over active rust is a wasted afternoon. The scale gets removed back to sound metal, the remaining rust gets converted or the section gets primed with a rust inhibitive primer, and only then does color go on. Sheltered sections and sun exposed sections often need different attention on the same gate.

Caulking, Masking and Living in the House

Joints get caulked before the topcoat, not after, and they get tooled rather than smeared. A bead that is left proud collects dirt and reads as a shadow line for the life of the paint.

Masking is the part that decides whether you enjoy the job. Windows, hardware, light fixtures, tile roofs, walkways and any planting close to the wall. On the narrow lots here that also means protecting the neighbor’s side, because there is often less than ten feet between the two houses.

We work in occupied homes almost exclusively, including a lot of rentals turning over between tenants, so the site gets cleaned up at the end of each day and access to the front door stays open. Staging and parking get worked out during the estimate, because a permit parking block with no driveway does not accommodate a compressor being figured out on the morning of day one.

Number of Coats, and the One Coat Quote

Over a color change, two coats. Over a heavily faded south or west elevation, sometimes two even when the color is not changing, because UV has broken down the old film unevenly and one coat lands patchy.

A one coat quote will always be cheaper than ours and it is not the same job. What it usually means is a thinner total film that fails first on the elevations taking the most sun, which are the ones you look at from the street.

Dry Time Versus Cure Time

A coating that is dry to the touch is not a coating that has cured. Recoat windows and full cure are different numbers, and full cure is where the hardness and the washability live. We schedule against the real numbers, and we will tell you to keep hoses, furniture and ladders off a fresh wall for longer than feels necessary.
