Sakač is an architect by profession and this has been reflected in his painting and in his seeking artistic expression. This coherent entirety has generated from his seeking, proving his vital creativity and enviable production. His prior abstract art, where he has been present during the last years, has been characterized by the irregular but controlled lines creating strong architectural structures with a powerful feeling of composition and achieving rudimentary forms. In his prior cycles and paintings the space has been suggested by lines,
the windows and doors have been suggested by squares, the poplar-trees by ovals etc. He has gradually reduced the motifs that have been only discernible under the thick fine paint coats as he has insisted on the materiality physically incorporated in his paintings. He has suppressed the color palette and has restricted the tonal range. Therefore, black, grey and white shades, sometimes with bluish tints have dominated the paintings, while some structures have been occasionally accentuated and dynamized by ochre yellow and red.
