Detailed Product Benefits:

The Everbuild 402 Waterseal forms a breathable, water-repellent barrier that prevents rainwater absorption while allowing trapped moisture within walls to evaporate. This helps to prevent efflorescence, spalling, and frost damage over time.

The transparent finish ensures no change to the colour or texture of treated surfaces.
