Breathable Paint & Breathable Masonry Paints for interior & exterior walls, and woodwork

Natural breathable paint and eco friendly breathable paints.

 

What are breathable paints?

Breathable wall paints are designed to allow moisture or water vapour to escape and permeate through it. If there is any form of dampness within your walls, you need the moisture to be able to be released and evaporate, rather than being trapped behind the paint thus leading to bobbles, blister and spots on your paintwork.

This range of fab Graphenstone eco paints are all great for breathability. Which breathable paint should I use on normal walls and ceilings? Easy. Just use the Grafclean Premium.

By using a ‘standard’ petrochemical plastic paint, you are giving no choice to the moisture, and effectively trapping behind your paint within your plaster or render, so you would want to use a natural and breathable paint for damp walls. You would never want your walls to be sealed in this way. Although it seems you are making them ‘waterproof’ and stopping the water penetrating, you actually you are just trapping the moisture within the fabric of your walls, leading to deterioration and more problems down the line due to this short term fix.

Breathable paint for damp walls, stone walls, internal walls & cellar walls

breathable paint has special microporous characteristics allowing water vapour permeate through materials. The rates of permeability are defined with an Sd value, which measures how much of a barrier the material is to water vapour. The lower the Sd value, the more breathable the paint is. Sd values of common breathable paints range from 0.02m to 0.5m, meaning that an Sd value of 0.5 is the equivalent to 50cm of air barrier.

Breathable paints such as lime based natural paints allow water to evaporate away quickly letting the walls, the window frames, the door frames and the render to breathe naturally without trapping moisture. So they are ideal for rooms with large moisture and temperature fluctuations such as kitchens, basements, bathrooms and laundry rooms. Breathable paint for damp walls.

What is breathable paint and why does it matter?

How is it possible that houses built decades ago maintain their plaster and walls in an excellent condition, when more recent construction and builds in the same city are in poor condition after just a few years? This is because that buildings need to breathe.

Everyone knows that when an old wall is painted it has the ability to change the mood of the occupants. But the colour of the paint is not the only thing that matters. Its compounds can protect or harm our health and our house.

In the past, people used to cover their stone walls with lime and plaster, using a minimum amount of cement, so they had achieved good breathability of their houses. As time went by, the use of various chemical insulation, abundant cement and finally coating with plastic petrochemical paint on top creating a very thin -but without pores – membrane led to perfect insulation.

However, humidity, unhealthy volatile components contained in the various chemical based paints used for furniture, radiators and walls and other harmful everyday materials such as toxic cleaning supplies, etc. are trapped inside the house. The use of breathable natural paints which are friendlier not only to our health and the environment, but to our homes, as well are the logical solution.

The point is: Keep old walls breathing and save them from building up a damp problem by allowing the moisture to escape through breathable materials. Clay paint was an 'original' breathable paint, as was lime – but modern natural paints like many in our range outperform these by a long way.

 

What are the advantages of Breathable paint?

 

  • They hardly ‘crack’, because no moisture is trapped into the materials.
  • Breathable paint helps to prevents wood rot, as moisture gets away.
  • They create a healthy indoor microclimate.
  • Natural materials and eco conscious manufacture.
  • They have no or low odour. They don’t emit VOC, or have very minimal VOC content.
  • Easy to apply to walls and ceilings. We would advise using a roller or brush.
  • They are economical.
  • They can be used for coatings on surfaces containing lime and cement, loam rendering, woodchip wallpaper or old chalk silicate paints. They provide high coverage.
  • They have both internal and external applications.They can be easily cleaned by light sponging.

 

Are breathable paints easy to use and to apply?

Yes, breathable paints apply in pretty much the same way as standard petrochemical paint, no extra skill needed!

What kind of applications can I use breathable paint for?

There are a great deal of applications for breathable paint, such as using breathable paint for lime plaster, or using them as a breathable emulsion paint for porous renders. We offer paints for the best microporous masonry paint, both exterior breathable paint or breathable paint for interiors.

Where can I buy a highly breathable paint?

Plenty of places offer it, but whether it contains chemicals is another matter, so I suggest you look at the range we have here.

Should I think about breathability before renovation?

If you are about to start a renovation, remodelling, or construction of your building, then there are a lot of things you would need to educate yourself on to be able to make the best possible choices for your home. One parameter that you need to assess is the paint your home is going to be covered in, both externally and internally.

A lot of the modern paints you would find on the market contain certain pigments, binders, and solvents that are packed with harmful chemicals. These chemicals can be detrimental to human health and the environment. If this wasn’t enough for you to reevaluate your choices and look for healthier alternatives, these synthetically formulated paints might also reduce your building performance by giving way to condensation and mould problems.

What is the Impact of Humidity and Temperature on Paint

The weather conditions have a considerable impact on the quality and performance of the paint. Wind speeds, temperatures, precipitation and moisture content in the air undermine the process of painting and repainting. In this article, we will discuss two of the most important factors that influence synthetic paints: temperature and humidity. These two greatly influence the painting and drying phases of paint application, as well as the durability and longevity of paint afterward.
Plenty of places offer it, but whether it contains chemicals is another matter, so I suggest you look at the range we have here.

What is the effect of Temperature on Paint

In colder temperatures, the drying of paint is comparably slower. This is because paint starts to come together into a thicker than usual coat of paint. It reduces the rate at which the solvent evaporates, and increases the time taken for the paint to oxidise if the paint is oil-based. The opposite happens in the case of higher temperatures. The paint dries too quickly and results in cracking, uneven coat, and lumps.

What is the effect of Humidity on Paint

Humidity also has plenty of undesirable effects on the application of paint. In a highly humid environment, water in the atmosphere can mingle with the fresh coat of paint, reducing both the quality and application of the paint. Higher water content in the atmosphere also impairs the drying process and makes it longer for latex and acrylic paints to dry. In case you are painting wooden surfaces, humid environments can seep into the wooden structure and reduce its binding affinity to the paint.

Are Breathable Paints the Answer to These Problems?

Breathable paints work well in fluctuating weather conditions, both interior and exterior Breathable paints, depending on their formulation, can readily adapt to the environment. For instance, lime-based breathable paints work great in humid conditions. These paints absorb the moisture content in the air, reducing the humidity of the environment, and release moisture into the air in the dryer and arid atmospheric conditions. With breathable paints, you wouldn't have to worry about reducing paint performance if you live in fluctuating weather conditions.

 

How do I Identify a Breathable Paint from the SD Value?

Even though you can always read the label of paints to check whether the product is breathable or not, we think you should also be able to identify breathable paints in the absence of it. What you need to look for on the paint label is the SD value of the pant. An SD value describes how well a material is able to resist the passage of water, or moisture, through it. Higher SD value indicates greater resistance to vapour diffusion, whereas lower SD values show higher water permeability. Breathable paints are supposed to have lower SD values, ranging from 0.01 to 0.1.

Does My Building Need Breathable Paint?

Whether or not your building needs a breathable paint depends entirely on the construction of your building. If your building is adequately porous and constructed from more natural and organic materials like clay, wood, cellulose, etc., you might not direly need breathable paint because an organic structure allows for water permeability and ample ventilation.

In the case that your building is of modern construction and made of synthetic materials like plastic, cement, or such, then you might find yourself in a very impermeable building. While you might be inclined to think that it would offer better insulation, which is true, these buildings are more prone to mould and condensation problems because they facilitate the buildup of water within the building which can severely undermine building performance.

By using breathable paint on your internal walls, you help improve the indoor air quality and ambiance of your building. Breathable paints help regulate humidity by absorbing excess moisture and releasing it in drier conditions – meaning they basically act as organic dehumidifiers. So if you're living in a hot and humid climate, your house would be more prone to condensation problems, which means you should definitely look into your options in breathable paint.

What are the types of Breathable Paint?

In an ever-evolving market, you would find a range of breathable paint from different brands. The market is pretty competitive, and more and more companies are coming up with new and innovative formulations to satisfy consumer demand. Some of the most popular breathable paints you would find in the market are:

Lime-based breathable paints

Lime-based paints, particularly lime-wash, have been around for quite some time because of their eco-friendly constitution and colour availability. These paints work well on lime-rendered and porous surfaces. What's more, is that these paints all provide good wall coverage and great breathability. If your building has some old and damp walls, or if you have a basement, you might want to consider lime-based paints as an option.

Clay Paints breathable paints

Clay paints are also very popular in the category of breathable paints. They offer great breathability and work very well on almost all surfaces, even pre-painted walls, and plain plaster. However we have yet to find a long lasting and true natural clay paint.

Natural breathable paints

Most of the paint that is naturally made is quite breathable and suitable paint, but you would have to check the SD value of the product to confirm this. Exterior Paint and interior paints made from natural ingredients like earth oxide pigments, minerals, or casein protein allow for good water permeability and contribute to lower SD values and a good level of breathability.
