Protective coatings can be good options for iron and steel objects. They help retain original appearance and protect against foreign bodies such as moisture and debris that can cause rust or corrosion. Clear coatings – Permalac [9] – Ormocer [10] – Paraloid B-72 [11]
Rust converters are chemical solutions or primers that can be applied directly to an iron or iron alloy surface to convert iron oxides into a protective chemical barrier. These compounds interact with iron oxides, especially iron(III) oxide , converting them into an adherent black layer ( black oxide ) that is more resistant to moisture and ...
There is solvent-based and water-based. Solvent-based acrylic paints are soluble in mineral spirits, and water-based acrylic paints are water-soluble. Acrylic paint differs from oil paint in both its quick drying time, and how the paint dries. Acrylic paint dries in as little as thirty minutes, and dries by the evaporation of the solvent or ...

"Strappo" involves the removal of only the uppermost pigment-bearing layer; "stacco" is the removal of the fresco and its plaster preparation; "stacco a massello" is the removal of the ...

The back of the fresco is thinned to remove excess lime and reconstructed with a permanent backing made from two thin cotton cloths, called velatini, and a heavier cloth with a layer of glue.
Phosphate conversion coating is a chemical treatment applied to steel parts that creates a thin adhering layer of iron, zinc, or manganese phosphates to improve corrosion resistance or lubrication or as a foundation for subsequent coatings or painting.
Custom strainers or inner panelings that are fit to the painting and secured with screws, therefore offering strength to the painting and allowing hanging devices to be attached without damaging a painting. [24] Cradling – Cradling refers to the addition of wooden supports or frames on the back of paintings. These slats require flexibility to ...
