External Walls

Externally, walls are subject to many external influences; rain, wind, snow and fluctuating temperatures being the most usual causes of erosion and damage to buildings. However, increased industrialisation has added more aggressive pollutants to the environment, accelerating the damage to building surfaces. 3M™ Scotchkote™ liquid coatings provide durable protection of all types of building fabric from degradation due to environmental factors.
