Exterior Painting

Four Walls, Four Different Jobs

An exterior repaint in Santa Monica is really several jobs sharing a scaffold. The elevation facing the water is carrying a salt film, more hours of surface damp out of the marine layer, and on the west and south faces the hardest afternoon UV in the day. The elevation facing the street behind a neighbour’s hedge is barely weathering at all. Coating them identically means one of them is over-specced and the other is under-specced, and you find out which about four years later.

So the survey walks all four faces before anyone quotes. We are looking for edge lift around cut lines and trim, chalk that comes off on a hand, rust bleed at fastener heads, hairline map cracking in stucco, and any place where a coating is still stuck but has gone brittle and glassy. On the sheltered sides that list is usually short.

Prep Is Most of the Money

The part owners underestimate is that surface preparation is the majority of the labour and effectively all of the durability. Paint does not fail because of what is in the can, it fails because of what was under it.

The order does not vary much. Wash the whole elevation down to get the salt and the accumulated grime off, and let it dry properly rather than nominally. Scrape everything that is loose. Feather the remaining edges so the transition does not telegraph through the new film. Treat rust on any exposed metal. Caulk the joints, around window and door frames, at trim junctions and where dissimilar materials meet, because an uncaulked joint on the weather side is an open route into the wall. Then prime what is bare.

Primer choice is not a formality. A bonding primer is for a chalky or glossy surface that a topcoat will not grip. A stain blocking primer is for tannin bleed, water marks and rust staining that will otherwise ghost through. A masonry primer is for bare or patched stucco, where alkalinity would attack an ordinary film. Using one product for all three situations is common and it is where a repaint quietly goes wrong.

Product and Sheen

For the body of a house here we use a quality one hundred percent acrylic exterior, which stays flexible and holds colour against UV far better than the cheaper vinyl blends. On the salt-facing walls we generally step up the sheen ladder from flat to a low sheen or satin. A flatter finish hides substrate imperfection, which is why it is popular, but it also holds deposits in its surface texture. A slightly tighter film sheds salt and dust and can be hosed down without burnishing.

Trim, fascia and doors are a different conversation. Acrylic latex trim enamels have improved enormously and they will not yellow, which matters on a white trim colour. A traditional alkyd still lays down flatter and harder on a front door or a handrail if you can accept slower cure and some ambering. We will tell you which one we would use on your door and why.

Two coats over any colour change. One coat quotes exist and they come back within a couple of seasons as patchy coverage, especially on a south wall where UV finds every thin spot.

Working the Weather and the Street

Exterior work here is scheduled around dew point and surface temperature, not around the calendar. If the marine layer has not lifted and the wall is sitting close to dew point, coating it traps moisture under the film and you get adhesion loss that looks exactly like bad paint. Most days the productive window opens mid morning. We would rather lose two hours than lose a wall.

The other constraint is the street. Narrow lots, permit parking and driveways that will not take a second vehicle mean staging has to be planned rather than improvised. We work off one vehicle where we can, keep the ladders and drops out of the neighbours’ access, mask and contain daily, and close the site down each evening rather than leaving an occupied house open.

What You Get Told

If two of your elevations are sound, we will quote the two that are not and explain what to watch on the others. If the body colour has faded enough that a partial recoat will read as two colours, we will say so before you commit rather than after. And if the substrate underneath is taking water from somewhere, we stop and find the source, because painting over a wet wall is the one thing here guaranteed to waste your money.
