But how are consumers meant to know how the VOC level will affect the paints performance? We've learnt that another leading brand, Crown do place a message on one of their tins warning that yellowing could take place but there are no such warnings on Dulux tins, so their customers only become aware of the problem when it's too late. Again, this was important information only found out when it was too late. Perhaps if Dulux had made it known earlier, the steady drip, drip, drip of complaints to Watchdog would have dried up long ago.
In response to the item being aired by the BBC's Watchdog programme about Dulux Pure Brilliant White gloss and satinwood products discolouring under certain conditions:. A piece of EU legislation was brought into effect on 1 January to reduce the amount of a particular type of solvent, known as 'VOCs', which were allowed to be in paint products. This was because of the impact which VOCs have on the environment. As a sustainable company, we were fully supportive of the legislative change.
All manufacturers who had paint products with VOC levels higher than a certain level had to change their products to comply. In changing the formulation, and despite rigorous testing, it became clear that in some conditions, early versions of the 'new' paint formulations were more prone to yellowing after application.
We addressed this issue in by reformulating our Pure Brilliant White gloss and satinwood paints. The result is a restriction of VOC contents within the paint industry. With the new legislation being introduced in painting manufacturers sought to find a solution to the new limits of solvent regulations in the UK. This prompted manufacturers to replace it with an increase of drying oil components to aid in the finish of gloss paint.
Unfortunately, an unknown side effect of the introduction of additional drying oil components resulted. With previous well-established paint mixtures boasting long-lasting white gloss finish the new mixtures failed to provide the same quality that many homeowners came to expect from their paint finish. The result was the yellowing of paint over time, with some gloss paints yellowing in a matter of months or even weeks after application.
The issue has affected all oil-based gloss paint manufacturers within the UK. For the best results and to avoid yellowing of gloss paint the solution is a high-quality water-based paint, A Water-based gloss paint will not yellow over time. The best way is to avoid the possibility of yellowing gloss is by choosing a water-based gloss and with the ongoing development of WB paints, new products are coming to market that offers better durability and more hard-wearing capabilities that can often rival those of oil-based solvents.
Water-based paints benefit from reduced drying times compared to oil-based paints and can often be dry to touch within an hour or two. While they often need multiple coats to be fully opaque the reduced drying time means the task of re-application does not have to be a lengthy process. You can expect water-based paints to be water-soluble and easy to clean making the painting process smooth and non-troublesome but the paint will become water-resistant when dry.
Containing microscopic plastic particles of binder such as acrylic, PVA or alkyd it is less harmful to the environment than oil-based solvents. Many thanks, Paul Cutting Edge Decor.

Hello, There could be a number of reasons why the paintwork is going yellow quickly but the hmost common ones are probably poor preparation where the woodwork has not been cleaned down properly especially if it is or has been a home of heavy smokers and the nicotene staining is bleeding through the finished coat.
Real open fires can cause staining aswell. This will be worse if a water based gloss was used and a sealer was not applied first. If the rooms are constantly very warm then the paint tends to yellow quickly. Also if cheap DIY paint has been used and not a good quality trade paint then this wont help either. A good quality water based paint will stay white unlike an oil based paint but will require more coats for a perfect finish.
Paint manufacturers have to comply with the new health and safety guidlines now for VOCs so the paint has changed alot from a few years ago so better for your Health now ,but some would say not as good for decorating with. Hi There. To shed more light on the paintwork, move any furniture blocking it and draw open the curtains of a nearby window if the room has one during daylight hours. Moisture from water, cooking grease, or cigarette smoke can also impart a yellow tinge to paintwork.
If you suspect that a leak is behind a water stain, suss out the source of the leak and repair it. Then, gently sand down the stain with medium-grade sandpaper and use a paintbrush to cover the spot with stain-blocking primer in the same shade as the painted surface. To remove cooking grease, fumes, or cigarette smoke, don gloves and goggles, dilute a quarter cup of trisodium phosphate in a gallon of water, then dip a sponge in the solution and wipe down the stain to remove it.
Dry the area with a clean rag.
