oil paint yellowing.

Hi. If it is its been kept from me. Traditional oil based paints will always yellow over time. There are factors that speed up and effect the yellowing, areas where there is little natural light, and the conditions in which the paint was applied at the time...... i.e Cold and damp air. Different brands yellow quicker than others. Ive switched to using water based trim paint because it stays white. But on the rare occasion i am asked to finish in traditional gloss i only use dulux trade pbw Edit. Yes dulux trade gloss is durable and stays white longer than others. The formulas changed in 2010 to lower the vocs. Dulux had a disaster with this initially but are back where things should be now As i say in areas that achieve natural light it will stay white pretty well Ive just used it in a 4 bed house throughout and in terms of flow and finish no water based gloss compares but water based is better in terms of discolouration Its not reccomended you apply gloss directly to gloss. If youre happy with the finish you have now (smooth, no runs etc) then very lightly rub down, clean and then apply either a thin undercoat, coat. Or a 'supergrip' primer. The undercoating ensures adhesion and also assists the levelling and flow of the gloss coat

in 2006 the main problems started to occur when manufacturers of paint were told by the government to lower the VOC in paint (volatile organic compounds ) initially they all had problems and its only recently that the matter has been resolved by improving the formula of the paint so................ there is no hacks or trade secrets that will stop paint yellowing by adding things best advice use Dulux trade paints they will last longer without yellowing than other brands
