Quakertown, Bucks County

Skim coating in Quakertown, PA.

Quakertown is a masonry town of twins, rows and big square houses, and more than a quarter of its homes predate 1940. Plaster on stone and brick walls gets patched in its own particular ways.

Skim coating for Quakertown homes

Square, solid and mostly masonry: that is how the National Register nomination describes the borough's houses, stone and brick with some of it stuccoed, two and a half stories tall. Inside, plaster on walls that heavy tends to stay put for generations, but it still collects cracks at window corners, filled holes from decades of hanging things, and patches where pipes and wiring were run.

Skim coating finishes what those repairs start. Once the cracks are taped and the loose spots rebuilt, thin coats go over the whole wall, so the old surface and the repairs read as one plaster wall again under paint. It keeps the plaster's mass and the original trim, which in houses this solid are worth keeping.

Quakertown

Masonry twins, rows and Foursquares

About 27 percent of the borough's homes were built before 1940, and most of the borough lies inside the Quakertown Historic District, listed in 2011 with 2,197 contributing buildings. The trolley, from 1896, brought blocks of row houses for factory workers, and the early 1900s added solid masonry Foursquares and Craftsman houses, most notably in the middle and northeast of the borough, along with Tohickon Heights, the area's first large subdivision, advertised in 1906.

A Foursquare's big square rooms show any unevenness across broad, unbroken walls, which makes them strong candidates for a full skim. The borough's largest postwar decade, the 1970s, added about a fifth of its homes, and drywall from those years tends to need popped fasteners reset and old patches flattened before any compound goes over it.

Worth knowing

  1. Richland walls, one at a time

    In Richland Township's newer houses, a skim is usually for the one wall a remodel or a removed fixture scarred, not for whole rooms.

  2. Later houses in the district

    The brick Capes, ranches and Colonials built later on single lots are usually drywall or gypsum-lath plaster, and they skim like the 1970s houses rather than the old masonry ones.

  3. Masonry holds the cold

    Thick stone and brick walls stay chilly through winter, so the rooms are kept heated before and during the work, which lets each coat dry evenly.

  1. Walkthrough and estimate

    Randy walks the rooms with you, looks at how sound the plaster and old paint are, and explains what each wall needs. The walkthrough and written estimate are complimentary.

  2. Repairs first

    Loose plaster is reattached, cracks are opened and bridged with mesh tape, and deep holes are filled with setting-type compound, which shrinks less than ordinary joint compound. A skim over an unsound wall only hides the problem for a while.

  3. Clean, dull, seal

    Walls are washed and glossy paint is dulled so the compound can grip. Torn paper facing and leftover wallpaper paste are sealed with an oil- or shellac-based primer, because water in the compound would make them bubble.

  4. Thin coats, edge to edge

    Compound is spread over the whole wall and wiped back tight, then left to dry hard before the next pass. Thin coats, never one heavy one: thick compound shrinks and cracks as it dries.

  5. Sand, prime, paint

    The dry wall is sanded smooth and cleaned of dust. Primer evens out how the surface absorbs, so the paint dries to the same sheen everywhere.

Questions

Skim coating, Quakertown.

Our Quakertown Foursquare was split into two units years ago and has patched ceilings where walls came out. Can a skim coat hide that?

Yes. The strip where each wall stood is filled flush with the ceiling around it and the joints taped, then the whole ceiling is skimmed, not just the strip. Patched alone, the old line tends to show the moment light crosses the ceiling.

A crack at the same window corner in our Quakertown twin keeps coming back. Will a skim coat stop it?

Not on its own. A crack that returns after filling usually means some movement, so it is opened, bridged with mesh tape in setting compound and only then skimmed over. If it keeps widening, the masonry or framing needs a look from a structural engineer before any finisher touches it.

Is the trim painted before or after the walls are skimmed?

After. Sanding a skim coat makes fine dust that would settle into fresh trim paint, and the compound is feathered tight to the casings and baseboards, so the woodwork is painted once the walls are skimmed and primed.
