MuralColors will revise a sequence of treatments to accommodate the current construction conditions and prior to any further structural enhancements. The recommendations in this conservation estimate may change based on site conditions, and as coordination takes place with the Client's GC, and related trades. SUMMARY OF MURAL CONDITION A detailed condition report and preliminary assessment of the artwork was provided to the client. The following is provided for context and reference purposes. Mural Condition and Recommendations for Conservation The mural is composed of various acrylic paints on top of a layer of white plaster that was used as a priming and smoothing substrate by the artist on an unfilled masonry block wall. The acrylic film seems to have been extended. The surface has evidence of the artist using a glazing technique to apply thin translucent layers of pigment. The paint film appears uncoated. There is efflorescence on the acrylic paint, which is a build-up of salts on the surface of the structure that obscures the paint and makes it appear faded. The efflorescence appears to be consistent throughout, and most concentrated over blue hued pigments and near wall fissures and the base of the wall. The paint film lacks flexibility and exhibits some pigment and binder deterioration throughout, especially in the skin tones, reds, yellows and orange hues. There is paint delamination in several areas of the mural where paint has peeled and raw concrete is exposed with,no evidence of the priming layer. The primed layer has poor adhesion and is compromising the paint film's bond to the wall structure where water has permeated. The paint film is delaminating primarily at the bottom of the mural, indicating the presence of moisture seepage at the base of the mural. Mildew and sediment development in the surrounding areas indicate that there may be poor drainage contributing to the wall absorbing moisture in these areas. MuralColors conducted four patch tests on the mural, each focusing on different areas and pigments with the goal of determining if the surface could be cleaned and consolidated in order to improve substrate adhesion and regain flexibility in the paint film. The patch tests indicate that a mild detergent for fine-art surfaces successfully begins to dissolve build-up of efflorescence and pollutants. The patch tests also indicate that chemical consolidation is capable of improving the surface characteristics; the restored pigment after consolidation remained evident in patch tests on the second and third site visits. We were unable to fully determine if the consolidation migrated into the plaster substrate beneath. More treatments may be necessary post construction to increase paint adhesion to the wall structure. Chemical consolidation is a conventional procedure for managing paint delamination. Reinforcement of the paint film along the wall fissures will be necessary before any structural repairs can be done.
