Permokapar Silicone Exterior Covering Primer, Water-based white insulating exterior primer on the basis of acrylic emulsion with the addition of silicone. Recommended touse when changing from one colour to another. Prepares a strong base for the last layer of paint applied to mineral surfaces. Filling voids, reduces the number of consumables. Leaves a thin layer of film, which enhances the coating ability of the paint. Has a high water vapor permeability. The porous structure allows the wall to breathe. The silicone component protects the surface from the negative effects of the environment, such as rain. Prevents premature drying of the paint. Helps to avoid colour heterogeneity when painting surfaces having different degrees of ink absorption. Reduces the complexity of work when painting previously painted surfaces. When working with surfaces that are highly absorbent and prone to dust, it is recommended to use Permolit Permobinder.
