    Can anybody offer an guidance for the anti-cracking mortar formula?

    42.5 Cement:400kg, sand 40-70:600KG, cellulose 200,000 viscosity: 2KG, Redispersible Polymer powder:5.5kg, the cost is cheaper compare others on the market. After 30 hours on the wall, rub it with hands and there is a slight white. Can anybody offer a solution?
