A Simple Process, Carefully Applied
Property Assessment
Before any treatment is applied, the property and masonry should be assessed to determine whether the treatment is suitable.
Different building materials and surfaces can behave differently, so suitability should always be considered on an individual basis.
Surface Preparation
The masonry is checked and prepared ready for application.
The aim is to ensure the appropriate surfaces are in a suitable condition for the treatment to be applied effectively.
Professional Application
The treatment can be applied using a brush, roller or airless sprayer, depending on the surface and application requirements.
It penetrates into the masonry and bonds with the building material rather than simply forming a surface coating.
Water-Repellent Protection
Once treated, the masonry becomes highly water-repellent, helping to prevent rainwater from penetrating the wall.
The treatment is designed to protect the masonry without changing its appearance.
Deep Penetration
Protection That Goes Beyond the Surface
The treatment can penetrate up to 12mm into masonry, allowing it to extend beyond the depth of typical hairline cracks.
This deeper penetration helps provide protection against water ingress within the masonry rather than relying solely on a shallow surface treatment.
Penetration
Breathable Protection
Keeps Water Out. Allows Vapour Through.
One of the key properties of the treatment is that it remains vapour-permeable. It lines the pores within the masonry rather than completely blocking them.
This means liquid water is prevented from entering while water vapour can still pass through the wall. Any residual moisture within the masonry can therefore continue to evaporate, helping the wall to dry out.
Rainwater
Repelled
Liquid water cannot enter the masonry.
Water Vapour
Allowed Through
The wall can continue to breathe and dry out.
Single-Coat Application
Long-Term Protection From One Application
The technical information states that a single coat can provide protection against rain penetration for at least 25 years.
This makes the application straightforward while providing long-term protection for suitable masonry.

Where It Can Be Applied
Suitable Masonry and Building Materials
The treatment is designed for application to a range of building materials, including:
The supplied technical information also notes that the treatment has been laboratory tested across more than 50 substrates. Suitability depends on the individual material and property, which is why Kosi-Dry assesses the masonry before application.
The Result
Protection Without Changing the Appearance
The treatment absorbs into and bonds with the building materials, making them water-repellent without changing their appearance.
The result is designed to provide long-term protection from rainwater penetration while allowing the masonry to remain vapour-permeable.

Water-Repellent
Helps prevent rainwater from penetrating the wall.
Vapour-Permeable
Allows the masonry to continue to breathe.
Long-Term Protection
A single coat providing protection for years.
Deep Penetration
Protection Beneath the Surface
The treatment penetrates deep into the masonry, beyond the depth of typical hairline cracks. This deeper protection helps guard the structure from water ingress rather than relying on a shallow surface layer alone.
A deeper treatment provides more substantial protection than a shallow coating, which can leave hairline cracks vulnerable to water penetration over time.
Breathable Protection
Water Out. Vapour Through.
The treatment remains vapour-permeable, allowing the masonry to continue to breathe. While liquid water is prevented from entering, water vapour can still pass through the wall.
This helps any residual moisture within the masonry to continue evaporating, supporting the wall to dry out naturally even in cold conditions.
