The lab area interior paint color is Sherwin Williams A100, 15yr warranty, exterior latex satin white.

The contractor shall coordinate access times and protocol with the USDA’s location personnel (see Section 2.5 below). The contractor shall excavate from the existing grade down to the building foundation from the exterior side of the kneewall and inspect all existing CMU and mortar joints and repair/replace/repoint as needed. Upon completion of the coating application the kneewall will be backfilled and compacted with a positive slope away from the building of 2% or greater.
