What material surfaces can cair paints be applied to?



Application on wooden surfaces is possible, but not recommended. Our paint is not able to replicate the natural beauty of wooden surfaces due to its matte-texture finish. If you wish to paint gush on wood, you would need to apply a layer of sealer first 




Application is also possible but not recommended. If you wish to paint gush on plastic, you would need to apply a layer of sealer first, to ensure the adhesiveness of the paint coat. 




cair / cair fresh interior paint should not be applied to metal surfaces, as it is a water-based, latex paint which may cause rusting of the metal surface.  



gush cair / cair fresh interior paint should never be used as a replacement for exterior paint as our paint formulation is specifically formulated for interior home settings.  

Do I mix water with cair paints?


Nope, you don’t need to! The cair series of interior  paints are formulated for immediate application straight from the tin. In fact, adding too much water risks reducing our paints’ efficacy and finish. Simply stir the paint well before use, and you’re good to go! 


Should you need to thin the paint, only clean water should be used to prevent contamination of the paint.Also, water added to paint should never exceed 15% of the overall paint solution as this would severely reduce our paints’ efficacy. 


Do I need to use sealer?

Sealer helps neutralise existing alkalis on the wall, which can cause peeling, staining or cracking of paint surfaces. It also helps remove excess moisture trapped within the walls, preventing mould and efflorescence growth. Additionally, sealer allows paint to adhere better to walls.  


We would especially recommend using sealer if:

  • There are previous issues with the wall, like hard-to-cover marks due to stains or grease, or patched-up areas 


  • You are changing from a dark to light colour 


  • This is the very first paint layer being applied to fresh drywall  


  • It has been 5 years since the last painting  


  • The wall was previously painted with an oil-based, emulsion paint 

Do you have a guide for painting with cair?

Yes, we do! Check out our instructional video here, by the wonderful Inch Chua.  
We hope you have fun painting your walls as much as she did! ?  

How long have cair paints been in the market?

gush interior paint has been sold publicly since 2017. The name ‘gush cair interior paint’ has been implemented since 2019.  

You can view our product testing and certifications here: 

How much paint should I get?

1 litre of gush paint gives you 2 coats for a  5-6 m² surface area. 


A standard 4-room HDB of around 90m² would therefore require about 45-50 litres of paint, for 2 coats.


Kindly note that the estimated quantity may differ for your home, based on how many walls you would need to paint. You can use our paint calculator, available on our colour pages, to estimate the amount of paint needed (click on Estimate Quantity”) 

What's the difference between cair and cair fresh?

cair fresh is a washable version of cair interior paint, but with reduced moisture absorbency. With cair fresh, you can easily wipe off stains and dirt from your surfaces without damaging the paint coat, while still enjoying our air-purifying benefits. 


We would recommend cair interior paint for the ceilings or areas with high moisture, and cair fresh for walls and areas prone to dirt, stains and marks. 

Is there a special application method to use cair paints?

Nope! Even with its air-purifying features, cair / cair fresh can be applied normally like every other paint in the market. We recommend applying 2 coats of paint layer to fully enjoy the benefits of our paint. 


Kindly note that the results of your painting may vary.

Paint Maintenance.

Please refer to our paint maintenance guide.


The paint warranty.

All paint purchases are covered by our Limited Lifetime Warranty.


Paint services provided by gush are covered under a 2-year anti-moulding warranty from the date of completion of your job.

How long do the benefits of cair last?

The air-purifying features of cair / cair fresh have been tested to last for up to 8 years.


We are also confident in our paint’s anti-moulding capabilities, and offer a two-year guarantee if you engage our painting services.


Our anti-bacterial capabilities should not deteriorate under normal usage. 

How durable is the paint?

The cair series of interior paints have been tested for durability in accordance to industry recommended SS 150: 2015 specifications, with the Wet Scrub Resistance test; in which a wear and tear simulation was used to assess the durability of the product. The lower the loss in thickness of the paint coating during the test, the greater the durability. The passing mark was 20 microns mean loss in thickness. At the end of the test, the sample of cair interior paint had a mean loss in thickness of 5.4 microns. 

Will the paint fade under exposure to normal sunlight into the room?

The paint might fade over prolonged exposure to sunlight, just as all paints will be subject to some form of gradual discolouration when in UV light. 

What do I do if my wall has existing moulding issues?


It’s best to remove any existing mould before applying gush paint.  


Doing it yourself? You can use mould removing solvents to scrub and wipe away any existing mould.  


If your mould problems are severe, we provide a range of mould removal treatments with our paint services. Contact our friendly gush representatives for more details. 


Upon removal of the mould, you must apply a layer of sealer before painting to minimise future potential mould growth. 

Are cair paints covered by a warranty?

As an original purchaser of our paints, you will be covered by a limited lifetimewarranty in which cracking, chipping, blistering or peeling from the paint, on properly prepared surfaces, are covered, subject to terms and conditions.
