Proteus - Protecting Exterior Walls

Exterior walls are a building's first line of defence against the elements, but they also serve an important aesthetic purpose, contributing to the overall appearance of the structure.

When choosing an exterior wall coating, it is important to consider both protection and aesthetics, with a coating that will shield walls from the weather and keep them looking their best for years to come.

At Proteus Waterproofing, we provide a selection of decorative coatings designed for performance that combine superior protection with stunning visual appeal. Our coatings are designed to meet the diverse needs of any project, from new construction to refurbishment.

Flexcrete: Ultra-Fast Drying for Minimal Disruption

Flexcrete, a rapid-drying water-based coating, offers effective protection against water ingress and carbonation. It is ideal for projects where time is of the essence, as it can be applied and dried in just a few hours. It is also highly flexible, making it resistant to cracking and peeling. It is also UV stable, so it will not fade or discolour over time.

Monosil: Invisible Protection for Sensitive Substrates

Monosil, a clear penetrating sealer, delivers inconspicuous protection against water ingress, carbonation, and other environmental hazards. It is ideal for use on sensitive substrates, such as brick, stone, and concrete. Monosil does not alter the appearance of the substrate, so it is perfect for preserving the natural beauty of exterior walls. It is also breathable, allowing moisture vapour to escape from the substrate.

Monodex: Textured Finish for Enhanced Aesthetics

Monodex, a textured coating, offers effective protection against water ingress and carbonation. It is ideal for use on exterior walls where a decorative finish is desired. It is available in a range of colours and textures, so you can create a unique look for your building. It is also highly durable and resistant to fading, cracking, and peeling.

Which Coating is Right for You?

The most suitable coating for your exterior walls will depend on your specific needs and requirements. Consider the following factors when making your decision:

• Substrate type: Some coatings are only suitable for certain substrates. For example, Monosil should not be used on concrete that has been treated with a curing compound

• Environmental conditions: The climate in your area will also play a role in your decision. For example, if you live in an area with extreme weather conditions, you will need a coating that is durable and UV stable

• Aesthetic requirements: If you are looking for a coating that will enhance the appearance of your exterior walls, consider choosing a textured coating such as Monodex
