Old Plaster Walls Fixed and Smoothed

Richmond's old walls are plaster, not drywall

The Fan. Church Hill. Older streets in Henrico. Walk into a Richmond home built before the 1950s and the walls are likely plaster — hard, thick, and very different from modern drywall.

Plaster cracks differently. It fails differently. And it needs a different fix. Spackling a plaster crack like it is drywall is why so many old-house cracks come back.

We repair plaster across Richmond, VA. Cracks, loose and bulging sections, crumbling patches, and whole walls that need skim-coating. We work with the plaster, not against it.

Plaster cracks vs drywall cracks

Drywall cracks follow the seams. Plaster cracks wander. They spiderweb from corners, run diagonal across walls, and trace the lines where the plaster keys broke behind the lath.

Hairline plaster cracks are usually just age and settling. The house has moved a bit over eighty years. Rigid plaster shows it. These cracks are cosmetic and very fixable.

Wide cracks, cracks with bulging, or plaster that sounds hollow when you tap it mean the plaster has let go of the lath behind it. The keys — the bits of plaster squeezed between the wood lath — broke off. That section needs reattaching, not just filling.

Tap the wall. Solid plaster rings hard. Loose plaster thuds hollow. That tap test tells us what the wall needs before we start.

How it works

For hairline cracks, we open the crack slightly, fill it with the right material, and finish it smooth. Plaster is harder than drywall compound, so the fill has to bond well and cure hard. Then we sand and blend.

For loose plaster, we reattach it. We drill small holes through the plaster. We inject adhesive behind it. Washers pull the plaster tight to the lath until the adhesive cures. Then we fill the holes and finish smooth. This saves the original wall.

For crumbled sections, we cut back to solid plaster. We patch with new plaster base, built up in layers like the original. Small areas can use modern patching compounds. But real plaster cures harder and matches better.

For walls that are sound but ugly — decades of bad patches, alligatored paint, rough texture — we skim-coat. Thin layers of compound over the whole wall, sanded smooth. The old wall stays. The surface becomes new.

Skim coating: a fresh start

Skim coating is the best-kept secret of old-house walls. Instead of tearing out plaster, we resurface it.

We spread thin coats of joint compound over the entire wall — two or three passes. Each coat fills the low spots and tightens the surface. Then we sand it smooth.

The result looks like a new drywall wall but keeps the solid feel of plaster. Old houses keep their character. The walls just stop looking tired.

Skim coating also buries old wallpaper residue and heavy texture. It covers the ghosts of bad patches too. One process, many flaws gone.

What we will not do

Straight talk on limits. We do not tear out good plaster to hang drywall unless the plaster is truly beyond saving. Original plaster is better than new drywall in almost every way — sound, fire, feel. We preserve it when we can.

We do not patch structural problems with plaster. If a crack comes from a failing foundation or a sagging beam, no wall fix holds. We tell you when the wall needs a different trade first.

And we do not rush plaster. It cures on its own schedule. Thin coats, full cure time, then finish. Old walls reward patience.

Working in old houses

Old houses have quirks and we plan for them. Plaster dust is heavier than drywall dust — we seal rooms tight. Old paint may contain lead, so we do not sand old paint layers aggressively and we contain what we disturb.

We protect original trim. Old woodwork cannot be replaced. We mask it and guard it before we start.

Most plaster jobs take a few days. Reattachment needs cure time. Skim coats need dry time. We schedule honestly and clean up every day.
