Restoration of Deteriorated Plaster

In many cases, old plaster can be restored to nearly pristine condition.

How about a Case History?



1. Strip

3. Primer plus Elastomeric Coating

2. Consolidate

4. Finish Coats and Gold Leaf

1. Strip

This has to be carefully performed in order to salvage as much of the old plaster as possible.



2. Consolidate

This process saturates the weakened plaster and hardens (consolidates) it, creating a sound surface on which to apply the protective coatings (paint).



3. Primer plus Elastomeric Coatings

After consolidating, the plaster is first sealed with an acrylic primer and then painted with a heavy bodied elastomeric coating. This coating helps fill in small cracks and voids and produces a flexible system that will protect for decades.



4. Finish Coats and Gold Leaf

Two coats of 100% acrylic finish paint are applied, along with a 24K gold “button”, to put the final touches on this plaster medallion.



Plaster: Restore or Replace ? Sometimes, the old plaster is so badly damaged that replacement is necessary.

Plaster Replacement

Deteriorated plaster is removed, as well as a relatively intact section, from which a rubber mold is created.

Badly decayed plaster has lost detailing.

Plaster Replacement

Newly cast plaster is allowed to dry completely (moisture meter used), sealed on all sides with consolidant, and then installed.

When finished, the new sections blend seamlessly with

the restored original plaster.

Plaster Replacement Example #2


Old deteriorated acanthus leaf plaster frieze band.

Approximately 80’ of curved and flat sections were removed. Of

interest, the original plaster used burlap for reinforcement.


Molds were produced from relatively intact sections of the original plaster, and then replacements were cast. Drying required 2 weeks and involved used of heat lamps. Note the moisture meter.

Plaster was first sealed on all sides with an epoxy primer, and installed with adhesive and stainless screws. Seams were then patched with epoxy filler.


An example of where the new plaster meets the original.

Once the new plaster was installed and patched, all sections (new and old) were primed with acrylic sealer and then finished with two coats of 100% acrylic paint.

Plaster Replacement

Additionally, on this same project we replaced three enormous portico brackets, as well as five ornamental frieze cartouches. All new plaster duplicated the originals.

“Portico Bracket”

Example #3

Painting Restoration….

Job completed.

Well, Almost….

A Little Carpentry, Anyone?

How does one get from this….

To this…?


FIRST, take it off.

A word to the wise:number every piece that is removed.


In this example, the quoins (corner blocks) were removed, rusted nails taken out, paint stripped, consolidated, and holes epoxy filled prior to re-installation.

Surfaces behind the quoins were cleaned up, consolidated, and epoxy filled.

Re-installation was performed with adhesive caulk and stainless steel screws (holes are always predrilled).


Hot dipped galvanized finish nails were then used to attach the smaller moldings to the face of each quoin.

A Little Carpentry, Anyone? In a majority of cases, moldings can be

salvaged by careful dismantling, restoring with epoxies, and re-installing. In instances where new duplicate moldings are required, that wood should be both consolidated and primed on all sides, including cut edges, before installation.

(Try telling that to a Building Contractor -most of them will just ignore you…)

Procedural Sequencing

From the Start :

• Meet with Owner, Initial Inspection and Prepare Budget for Project.

• Erect Scaffolding and Containments• Stripping and Prep Work begin.

(Be “Lead Aware”).• Revise as necessary the budget for

“Restoration” depending upon conditions uncovered.

• Epoxy Consolidation and Fillers applied.

• Carpentry and Other Repairs performed.

Procedural Sequencing

To the Finish :

• First Coat of Acrylic Primer applied.• Cosmetic Fillers.• Second Coat Primer applied as needed.• Caulking of seams, joints.• Finish Coat(s)

– Two coats minimum recommended on “Restored” & heavily exposed surfaces.

– 100% Acrylic. – Gold Leaf is indeed the final touch.

Another Result of Painting Restoration

And one in Progress

• IT’S AN ATTITUDE

• TREATS THE CAUSES – not just the

SYMPTOMS

• TECHNIQUES – learn and develop new ones

• EXPERIENCE Satisfaction – longest lasting jobs that look fabulous

• PRIDE of Ownership
