Polymer External Wall Putty
Features of Performance
High strength, excellent water, alkali and freeze-thaw resistance. High adhesion to surface of various walls and exterior coatings.
It has good waterproof property, high crack resistance because imported hydrophobic polymer is incorporated in the formulation.
The disadvantage of using traditional primer. such as random selection of materials and mixing ratio, low strength and poor water, alkali resistance, can be overcome. Moreover, workload and labor are saved, application is easier.
Scope of Application
It is widely used as a primer on external wall of various buildings including the walls made from cement mortar, concrete, TK board, gypsum board, pearlier board, aerated concrete block etc. providing flat, smooth and strong substrate for finishing of the external wall. The decorative effect of the wall finish can be greatly enhanced and service life of the exterior coating can be extended.

1. Mixing ratio :Liquid Putty: Putty Powder=1:2.5. Before application they must be stirred evenly first, the paste should be used up within 6 hours.
2. Adopts scraping method. Polish immediately after the layer is dry completely (approx. 3-4 hours), otherwise the putt), glue will be indurations cause smooth difficulty. Usually the external wall paint can be brushed after three days.
