Why is your Gloss turning Yellow?
Any homeowner looks for the perfect finish to their decor when it comes to painting as part of the DIY painting schedule. There is nothing better than pristine white woodwork once it has been painted with a fresh coat of gloss.
However, all homeowners are also familiar with the way in which gloss paint turns yellow after a period of time.
This change in colour can be extremely frustrating but there is a reason why it happens. Over time, all paints that are enamel solvent-based become oxidised. This then results in your white gloss paint taking on a yellow tinge.
Unfortunately, this is one of the downsides of using oil-based paints and varnishes and it is something that cannot be stopped.
However, the oxidisation process can speed up due to a number of factors and so, the list of causes below can help you to slow down the process, leaving your paintwork looking better for longer.
Oxidisation is a natural process and as the paint is exposed to oxygen, there is not a lot that can be done to prevent it. As a result, oil-based paints change colour but if you want to keep your paint looking white and as fresh as possible then natural and artificial light can help.
Commonly, inside cupboards or behind picture frames, you will notice a yellow tinge. However, enamel paint benefits from light when it comes to slowing down the process of oxidisation.
So, when paint turns yellow, you can reverse the process by simply exposing the paint to light.
Over a period of time, the yellow tinge will become less noticeable. However, the area will become yellow again should it not be exposed to light regularly.
Commonly, people will clean these areas using a range of cleaning products but many of these will contain ammonia. From household cleaners to floor polishes and even acrylic water-based paints, all of this can cause the paint to turn yellow.
Along with this, if the paintwork is located near to a heat source such as stoves, heaters and radiators, it can also cause the process of yellowing to speed up.
It is also possible for moisture to cause the same problem while cigarette smoke and grease from cooking can cause the paint to yellow. Therefore, if you are planning to paint an area, you should ensure that it is free from moisture while checking for any leaks or condensation.
What can also help the situation is good ventilation in areas such as bathrooms and kitchens as this is where grease and moisture can build up.
So, it is inevitable that gloss paint will turn yellow as that is something that happens through the process of oxidisation. Despite this, the process can occur faster due to a number of reasons. Therefore, if you can remove these factors, it can help to reduce the speed at which it becomes yellow, leaving the paint looking whiter for longer.
