This problem was mitigated by the introduction in the 1950s of vacuum hot-table processes, designed for use with wax-resin adhesives, which exerted a more even pressure on the paint surface; however the longer periods of heating and high temperatures involved often led to other types of textural alteration.

Painted surfaces have been consolidated with an acrylic resin diluted with deionized water and then injected into cracks, [12] as well as the use of antibiotics for the removal of bacteria. [ 13 ] The teams today also have more high-tech tools at their disposal, including lasers to clean the frescoes, and ultrasound, thermal imaging, and radar ...
Radiography can also be used to revel the opacity of specific paint colors. Degradation to the surface of panel paintings is often a sign of underlying structural issues, temperature and humidity fluctuations, and wood-boring pests.

Painting types include fine art to decorative and functional objects spanning from acrylics, frescoes, and oil paint on various surfaces, egg tempera on panels and canvas, lacquer painting, water color and more. Knowing the materials of any given painting and its support allows for the proper restoration and conservation practices.
Paraloid B-72 or B-72 is a thermoplastic resin that was created by Rohm and Haas for use as a surface coating and as a vehicle for flexographic ink.Subsequently, it has found popular use as an adhesive by conservator-restorers, specifically in the conservation and restoration of ceramic objects, glass objects, [1] the preparation of fossils, the hardening of piano hammers, [2] [3] and can also ...
Particulate resin is evenly distributed on all or parts of the plate, then heated to form a screen ground of uniform, but less than perfect, density. After etching, any exposed surface will result in a roughened (i.e., darkened) surface. Areas that are to be light in the final print are protected by varnishing between acid baths.
The result is a highly durable connection between paint coat and substrate. The water glass binding agent is highly resistant to UV light. While dispersions based on acrylate or silicone resin over the years tend to grow brittle, chalky, and crack under UV, the inorganic binder water glass remains stable.
Water transfer printing, also known as immersion printing, water transfer imaging, hydro dipping, watermarbling, cubic printing, Hydrographics, or HydroGraphics, is a method of applying printed designs to three-dimensional surfaces. The resulting combinations may be considered decorative art or applied art. The hydrographic process can be used ...
