The suggested formulation of cement based putty under nature stone paint This article introduces a quick method to test redispersible polymer powder (RDP) quality by making a film. Steps include mixing 10ml RDP powder with 10ml water, stirring for one minute, letting bubbles disappear, pouring on flat ground, and drying. A quality RDP film should have good color, flexibility, and strength.
