ROXSiL Breathable Paint

Your key to treating paint problems!


ROXSiL Breathable Paint is a breakthrough technology that conforms to Low Liquid Water Absorption and High Water Vapour Permeability – qualities which are referred to as “Breathability”. Breathability allows trapped moisture within cement-plastered walls to escape as vapour into the atmosphere. Our Breathable Paint System also includes a proprietary surface treatment that forms a layer of water resistance with water repellent properties inside cement walls, safeguarding against water intrusion.

Our paint technology stands up to major paint problems such as efflorescence, peeling, algal and fungal contamination and more. ROXSiL Breathable Paint ultimately enhances your home aesthetics and delivers a performance that is unrivalled by any ordinary paint.


ROXSiL Breathable Paint is designed for general use on exterior cement-rendered walls. It possesses the unique ability which allows it to lock into the cement surface. This leads to an increase in terms of adhesion strength, something which is usually not possible for ordinary paints. As we know, water trapped inside the walls is the number one cause of paint damage and that’s where the arrival of ROXSiL’s revolutionary technology matters: a paint that allows the wall to “breathe” while letting trapped water escape without harming the walls in any way.


Painting new walls had always been a problem in the past — until we discovered a method to make the paint you use to learn of its inner ability to “Breathe”. ROXSiL’s Breathable Paint System allows water to escape from newly plastered walls while staying resistant to the water against absorption.

Why is it vital to make a paint that is able “Breathe”? This is because traditionally, the paints that we use would form a plastic film that traps water. When the water behind the walls is subjected to sunlight, it allows moisture to penetrate through the paint film and this in turn will damage the paint in a number of ways. As it is, trapped water within walls is the number one reason of paint failure.

Blistering and Peeling

Ordinary acrylic paints are prone to blistering and peeling. Blistering occurs on a moist substrate where moisture inside the wall is trapped within the paint coats. The moisture which has accumulated beneath the paint will separate the coating from the substrate. This will affect the adhesion between the paint film and substrate while causing the paint to detach itself from the surface. Over time under extreme weathering conditions, this will lead to paint cracking and peeling.


When cement-plastered walls are exposed to various atmospheric conditions over a long period, it will be subjected to paint discolouration. This is because the energy from UV radiation can cause a change in the color of the paint. Paint pigments especially organic ones will break down and it will not retain the physical and chemical properties which it was designed for. Poor alkaline resistance of the paint film can also cause discolouration. Freshly painted walls needs to be cured for a certain duration to reduce its alkalinity. Failure to do so will result in an alkaline attack which is capable of affecting the paint film’s integrity and colour.


The process of a wall going through efflorescence involves the migration of salts to the surface of a porous material. In general, it can be described as whitish powder (salt deposits) that occasionally appears on the walls as it is carried to the surface by moisture. Low temperatures, condensation, rain, moisture, and water added to the surface of cracked porous substrates are among the causes of efflorescence.


The formation of loose, white powder on the surface of the paint film due to weathering, which may give the appearance of color fading. This can be caused by a combination of prolonged exposure to moisture and the sun’s UV rays. Other possible causes include using a low quality external emulsion paint and over-thinning the paint.

Algae and Fungus

Thriving in an environment that is damp or receives little to no sunlight, fungal or algal contamination can occur on the surface of the paint. Brown, black or gray in colour, it can also be caused by failing to use a paint that contains a sufficient amount of fungicide or algaecide.

Rising dampness

Moisture presence, be it in walls or from water in the ground underneath or next to walls rising up through the fabric of the wall is known as rising dampness. Rising dampness can affect brick, block, and stone walls. The way it happens is that the water travels upwards through the wall as a result of capillary action through the capillary tracks of the cement plaster. Gravity-affected rising dampness can sometimes reach the height of approximately 1 metre.
