This is the only remaining section of the transept wall that has not been painted. The water content is too high (above 40%). It has to be below 30% to paint. Otherwise, the paint will not adhere properly.
Last week, Ribbeck Construction workers removed the water soluble paint (calcimine) in order to get it ready for the new paint.
The apse wall behind the high altar is now painted.
Here's the color scheme and design patterns for the apse wall.
The through wall vents at the perimeter of the Cathedral are now closed up, and the historical look of the prior vent openings from the exterior is retained. This would solve many problems such as: reduce maintenance work, prevent further spalling of the underside of the concrete floor reinforcing, extinguish the need for cost of ductwork replacement, condition the crawl space expelling unwanted moisture.
