Drywall vs. Plaster:
Which Is Right for Your Home Renovation?
Myrtle Beach Elite Drywall has worked on both drywall and plaster surfaces across the Grand Strand for 20+ years! If you are renovating an older home — or building new and researching finish options — the drywall versus plaster question comes up early. Plaster was the dominant interior wall material in American residential construction until the 1950s, when drywall displaced it almost entirely due to speed and cost advantages. Today, plaster is rarely specified for new construction, but it appears regularly in renovation work on older homes, and understanding the practical differences between the two materials affects every decision from budget to finish timeline.

What Each Material Actually Is
Drywall — also called gypsum board, sheetrock, or wallboard — is a factory-manufactured panel of gypsum plaster pressed between two layers of paper facing. Panels are cut to size, fastened to framing, taped at joints, finished with joint compound, and painted. The entire process from hanging to paint-ready can be completed in three to five days on a standard room depending on compound drying time.
Plaster is a wet-applied wall system. Traditional three-coat plaster involves a scratch coat, a brown coat, and a finish coat, each applied by hand over a metal or wood lath substrate and allowed to cure before the next coat goes on. The process is labor-intensive, requires a skilled plasterer, and takes significantly longer than drywall installation — a full three-coat plaster system can take one to two weeks to cure before painting. Modern veneer plaster applies a thin finish coat over a specialized gypsum base board, compressing the process while retaining some of the hardness and finish quality of traditional plaster.
How They Compare on the Factors That Matter
Durability and Surface Hardness
This is the category where plaster has a genuine, measurable advantage. A fully cured three-coat plaster wall is significantly harder than drywall — it resists dents, scratches, and surface damage that would mar a drywall finish. In high-traffic areas like hallways, stairwells, and entryways, plaster outperforms drywall on longevity of the finished surface. Hardness also means plaster transmits less sound than an equivalent drywall partition — a standard plaster wall achieves STC ratings several points higher than a single-layer drywall wall on the same framing.
The trade-off is brittleness. Plaster does not flex with structural movement the way drywall can. In homes with settling foundations, seasonal wood movement, or seismic activity, plaster cracks — and plaster cracks are more difficult and expensive to repair than drywall cracks because matching the original finish coat requires skill that most drywall finishers do not have.
Installation Cost and Timeline
Drywall is faster and less expensive to install than plaster by a significant margin. Material costs for standard drywall run roughly $0.50 to $0.75 per square foot for the board alone; labor for hanging, taping, and finishing typically adds $1.50 to $3.00 per square foot depending on finish level and market. Three-coat plaster installation runs $8.00 to $15.00 per square foot installed in most markets, reflecting the higher material cost of lath and plaster materials and the longer labor hours required for a skilled plasterer to apply and cure three coats.
Veneer plaster — the modern hybrid system — sits between the two on cost, typically running $3.00 to $6.00 per square foot installed, and compresses the timeline to two to four days rather than one to two weeks.
Repairability
Drywall repairs are straightforward for any competent drywall contractor. Damaged sections are cut out, backing is added at the stud bays, new board is installed, and the repair is taped, finished, and textured to match. The challenge in repair work is texture matching — replicating the existing wall texture on the patch — but the underlying process is fast and predictable.
Plaster repair is more demanding. Matching a traditional plaster finish coat — particularly smooth trowel finishes, sand finishes, or decorative textures applied decades ago — requires a plasterer with specific skills that are increasingly uncommon. Many drywall contractors will patch plaster walls with joint compound rather than plaster, which produces a visible color and texture difference over time as the two materials age differently. In historic homes in Conway or older sections of Myrtle Beach, plaster repair done correctly costs more and takes longer than the equivalent drywall repair.
Moisture Performance in Coastal Markets
Standard drywall and standard plaster both absorb moisture — neither is inherently moisture-resistant in a coastal environment like the Grand Strand. Plaster's denser, harder surface is slightly more resistant to surface moisture penetration than drywall's paper facing, but both materials will deteriorate under sustained moisture exposure. The relevant comparison in Myrtle Beach's coastal climate is not drywall versus plaster — it is standard board versus moisture-resistant or mold-resistant board, which is a product specification decision within the drywall category. Mold-resistant fiberglass-faced drywall outperforms both standard drywall and standard plaster in sustained high-humidity environments.
Finish Quality Ceiling
A perfectly executed three-coat plaster finish, troweled smooth by a skilled plasterer, produces a harder, denser, and more uniform surface than even a Level 5 skim-coated drywall finish. Under raking light, the plaster surface is marginally superior. In practice, a Level 5 drywall finish executed correctly is indistinguishable from plaster under normal lighting conditions and is the standard for high-end residential and commercial interiors. The finish quality ceiling of drywall — Level 5 with a bonding primer — is sufficient for any residential or commercial application currently being built.
When Plaster Still Makes Sense
Plaster remains the correct choice in two specific scenarios. First, historic preservation work where the existing wall system is traditional plaster and local preservation standards or personal preference require matching the original material. Second, when the surface hardness advantage of plaster has functional value in a specific application — a high-traffic institutional space, for example, where surface durability over decades is more important than installation cost. In both cases, the work requires a plasterer with demonstrated skill in the specific plaster system being matched or installed. Outside these scenarios, drywall — specified correctly for the moisture environment and finished to the appropriate level — is the practical choice for residential and commercial renovation in virtually every application.
What This Means for Your Renovation
If you are renovating an older Grand Strand home with existing plaster walls and have no preservation requirement, the decision between repairing the plaster and converting to drywall comes down to the condition of the existing system and the scope of the renovation.
Plaster in good condition with isolated damage is worth repairing. Plaster that is extensively cracked, has widespread key failure — where the plaster has separated from the lath — or is being opened for electrical or plumbing work anyway is a reasonable candidate for conversion to drywall. Once lath is exposed, the incremental cost of removing it and installing new drywall is often lower than the cost of replastering the opened sections.
If you are building new or doing a full gut renovation, drywall is the correct material. Specify the board type for each location's moisture exposure — standard board in dry interior spaces, mold-resistant fiberglass-faced board in bathrooms, kitchens, laundry rooms, and any exterior wall in a coastal environment — and finish to the level appropriate for the paint sheen specified.
