Dip coating is an industrial coating process which is used, for example, to manufacture bulk products such as coated fabrics and condoms and specialised coatings for example in the biomedical field.
The foundations are made of brick and concrete, with lath and plaster cladding. [71] At the bottom of the facade is a concrete water table. [252] [d] Running horizontally, approximately 6.5 to 8.0 feet (2.0 to 2.4 m) above the water table, are concrete belt courses and friezes with hollyhock patterns. [252]
