Where does the term BLOB come from?
BLOB, or Binary Large Object, is an amoeba-like building shape. A shape that consists of an irregularly curved surface. The term BLOB was introduced by American architect Greg Lynn. He used this term in 1995 to describe the shape created by clicking a cloud of random points in a CAD computer program.
One of the first BLOBs built was the water pavilion (1997) on the Eastern Scheldt barrier by Kas Oosterhuis and Lars Spuybroek. Spuybroek in particular has made many designs for BLOB-like structures thereafter (source: Architectenweb).
BLOBs are often used for small pavilions or large buildings with a cultural function. Critics of blob shapes point out that they are more complicated to design and produce than strictly necessary.
Sealing a BLOB is a challenge
Sealing and coating BLOB designs can sometimes lead to major challenges. Prokol developed a number of Polyurea Hotspray coatings for this application, among others, which are characterised by a short drying time of 5 seconds. These short drying times, in combination with special spraying techniques, make it possible to seal all these special structures completely seamlessly.
