Deck Painting & staining across Cape Cod, Massachusetts.

Deck boards lie flat to the sky, hold rain in every seam, and collect sand and grit underfoot, so the stain or paint on them takes more wear than the coating on the walls of the same house.

Census data shows 81.6% of the county's housing units are single-family detached homes, and on a detached house there is no neighbor's railing or shared stair to match. Another 5.1% are single-family attached units, where a deck or railing can line up with a neighbor's and an association may set the color, the product or who does the work.

Choosing stain or paint for the wood you have

Penetrating finishes fade and wear rather than peel, which makes the next recoat a wash-and-apply job. Film-forming finishes protect longer against UV but fail by peeling, and every peeled patch must be scraped before recoating. The paint vs. stain deck comparison goes deeper into how each one ages.

• Pressure-treated pine: let new lumber dry until water soaks in rather than beading, then use a penetrating or semi-transparent stain
• Cedar and other naturally decay-resistant woods: penetrating oils and semi-transparent stains show the grain; light solid colors may need a tannin-blocking primer
• Tropical hardwoods: dense boards that resist absorption, so they need products made for hardwoods
• Composite decking: cleaned rather than coated unless the manufacturer approves a coating
• Boards that already have paint or solid stain: another film coat, or a full strip to bare wood before switching

Seasonal houses and spring timing

One in three housing units in Barnstable County, 33.1% by the Census count, is classified as held for seasonal, recreational or occasional use. In Truro the figure is 67.8%. For a deck that sits under snow and leaves until the house opens, the work is best lined up so cleaning, repairs and stain are finished before guests or the family arrive.

Stain needs boards that are dry several days after washing and rain, plus a dry forecast through the product's cure time. That means the spring window depends on the weather pattern that year rather than the calendar. Our post on how deck stain survives a New England winter covers stripping, sanding, moisture checks and product choice for boards that sit out the winter.

Low-lying lots and repairs before coating

The Cape Cod Commission notes that Truro, Falmouth and Provincetown have the most inventoried historic structures in flood zones, among them many small early-20th-century vacation cottages at Truro's Beach Point. On any lot where water pools or sits close to the framing, check post bases, the ledger board where the deck meets the house, stair stringers and the boards nearest the ground before anyone applies finish.

Soft, spongy or split boards should be replaced, popped nails reset or swapped for screws, and the whole surface cleaned of mildew and graying with a deck cleaner, then neutralized with a brightener. Light sanding knocks down raised fibers so the stain goes on evenly.

Historic districts and older porches

The Old King's Highway committees review changes to the exterior of buildings and structures, plus fences, and Brewster names color among the factors they weigh. If a deck, porch railing or stair is visible from the street in that district or in a Chapter 40C district in Barnstable, Dennis, Eastham, Falmouth, Harwich, Mashpee or Provincetown, check with the town before changing its color or materials.

With 56.4% of the county's housing built before 1980, a painted porch floor or railing on an older house may carry lead-based paint under newer coats. Paid scraping of that paint on a pre-1978 house falls under the EPA's lead-safe rule; see the lead-safe painting page. If the house itself is also due, the Cape exterior painting page covers historic review, lead-safe scraping and prep for the siding and trim.
