Limewash - Design - What is shelter coat and why would you use it?

A shelter coat limewash is a specialized type of limewash, that contains a fine aggregate, that is applied as a protective layer over an existing limewash or another surface treatment. It is designed to provide additional weather resistance and durability, particularly in exposed or harsh environments.

There are several reasons to use a shelter coat limewash:

1. Enhanced protection: Shelter coat limewash provides an extra layer of protection against moisture, and other environmental factors that can degrade the underlying surface.
2. Extended lifespan: By adding a shelter coat, you can prolong the lifespan of the underlying limewash or substrate, reducing the frequency of maintenance and repainting.
3. Improved aesthetics: Shelter coat limewash can enhance the appearance of the surface, providing a fresh and uniform finish while preserving the texture and character of the underlying material.
4. Increased durability: In areas prone to heavy rain, wind-driven rain, or other harsh conditions, a shelter coat can help prevent premature deterioration and damage to the surface.

The application process for a shelter coat limewash is the same to that of regular limewash. It involves cleaning the surface to be coated, preparing the limewash mixture, and applying it evenly using a brush. Multiple coats may be necessary to achieve the desired level of protection and appearance. It is normally only applied externally due to the textured finish the fine aggregate in the mix creates.

In summary, a shelter coat limewash provides added protection and durability to surfaces exposed to harsh environmental conditions, offering benefits such as enhanced lifespan, improved aesthetics, and increased weather resistance.
