Applying Clay Plaster Effects

Effects have mainly been developed for the decorative enrichment of the various Tierrafino wall finishing products. However, effects also influence the composition of the products. Straw is a fiber and the other Effects are sands that improve resistance against shrinkage cracks.

Other Effects: max. 10% of the dry weight of FINISH, DURO, BASE or T-Paint.

For every 0.1% Straw you would like to add, you can add 1% less other Effects than the maximum of 10% allowed
