Properties :
· Water repellant surface.
· If required, longer application time ( up to 72 hours)
· Optimum drying time.
· Excellent workability
· Excellent adherence
· Excellent flexibility, strength and durability
· Lightness
· Easy spreadability
· Improvement of the frost resistance properties
· Compatibility with all kinds of sand, cement and other additives
· Non-corrosive
· No excessive cracking
· Antibacterial protection.
PWR containes special additives that provide high flexibility, adherence and workability to the mortar. Additionally it containes special silicone polymers which renders the surface of the plaster, water repellant. This water repellancy does not impair the breathing of the wall.
