The role of the polymer
Redispersible polymer powder supports internal bonding and flexibility in cementitious putty. Evaluate its performance after the layer has dried.
Find the cause of weak adhesion
An unsuitable substrate, insufficient binder or excess water can also cause problems. Increasing RDP dosage is not always the answer.
Compare grades in the formulation
Assess adhesion, flexibility and stability under consistent conditions. This note summarises Celotech’s selection guide.
