The polymer is the type of additional material which has high adhesion and is deformable. This study aims to determine the effect of additional polymer against the value of the compressive creep, as well as to predict the long-term creep value based on existing short-term data and the possible error value. The method used in this research is to experiment in the laboratory. The object used in the study is a cylinder with a diameter of 75 mm and a height of 275 mm. The variations in polymer content that are used were 0%, 2%, 4%, and 6% of the cement weight. The data obtained on the creep values that occurred during the 84-day test The data analysis showed that the addition of polymer content in the repair mortar tended to decrease the creep value. The greater the polymer content, the smaller the creep value that will decrease. In the calculation of the obtained creep prediction, it showed a difference when compared to direct measurement. As the predicted value obtained has a large error value, it is necessary to modify the formula to get a more precise prediction.
