Master of Plaster

Specialty Plaster LLC extensively uses the Master of Plaster Finishing System.

What is Master of Plaster?

In short, Master of Plaster is a pre-mixed skim coat plaster which requires no bonding agents or sanding to obtain a premium level 5 surface. It is designed for restoration of antique plaster walls, ceilings, and ornament, but Master of Plaster is also well suited for new construction.

Why would anyone use Master of Plaster?

Master of Plaster is the only pre-mixed restoration plaster.

Master of Plaster is lime based, not gypsum based, which makes it a superior restoration plaster. Gypsum based plasters are sensitive to moisture and cracking. Lime plasters are soft, flexible, and breathable.

Master of Plaster is both historically accurate and green; no polymers, acrylics, or resins are present. Using Master of Plaster to restore the original plaster saves on construction waste and does not alter the historic fabric of old lime plastered buildings.

Where can Master of Plaster be used?

Master of Plaster requires no bonding agents. It bonds naturally to any clean sound surface including painted plaster, sheetrock, greenboard, blueboard, brick, and masonry.

Master of Plaster can be used on any interior surface, and it performs well in kitchens, bathrooms, showers, and exteriors.

Master of Plaster is a wet finish plastering system. Its application requires absolutely no sanding. Master of Plaster will produce all the traditional wet finishes which include Venetian, Marmorino, Scagliola, Marezzo, Caenstone, Granite, Travertine, and Brownstone.

Who should use Master of Plaster?

Anyone can become proficient at the Master of Plaster Finishing System in a short period of time.

We at Specialty Plaster LLC are willing to train both contractors and homeowners the Master of Plaster Finishing System. We offer private lessons and occasional classes.

Master of Plaster was specifically developed for the restoration of antique plasters which usually consist of lime and sand.

Q: Why not use cheaper gypsum veneer plaster (like Diamond/Imperial or Kal-Kote)?

A: Hard, dense gypsum veneer plasters are susceptible to cracking as the original plaster expands and contracts. Gypsum plasters are not very breathable. They will not release the moisture that gets trapped in exterior walls. The result is failure: delamination and cracking.
A smooth finish void of cat faces, trowel marks, and blisters is difficult to achieve with gypsum plaster. Master of Plaster easily produces surfaces suitable for critical lighting and glossy finishes.

Q: Why not skim coat with joint compound?
A: Joint compound is soft and very prone to abrasions and punctures.
Joint compounds act like a sponge for moisture because they are softer than the plaster; over time they will fail due to moisture build-up. The joint compound and paper tape eventually delaminate.

Master of Plaster, which is lime based, will expand and contract at the same rate as the original lime plaster, and it will allow the original plaster to breath properly. It can be polished to a beautifully smooth, blemishless, dense, durable surface, and it naturally bonds to the old painted plaster.
