From the mid 1980s, Richter began to use a home-made squeegee to rub and scrape the paint that he had applied in large bands across his canvases. This spread the paint over the surface and integrated the various colours with each other. In the 1990s the artist began to run his squeegee up and down the canvas in an ordered fashion to produce vertical columns that take on the look of a wall of planks. 'Abstraktes Bild (809-3)' is typical of these paintings. One effect of the use of the squeegee was to create a blurring of one area of colour into another – similar to the blurring in Richter’s earlier photo-paintings – so that one has the feeling of looking at an out of focus image, that lies tantalisingly beyond decipherment.
