Our recommendation to fix white cabinets that have yellowed is to do a thorough sanding and precleaning and recoat with the following products:

Haze (the technical term is blush) is caused by too many coats applied too quickly. A recoat time of 12 hours is not enough dry time when applying over an EXISTING finish. To remove the blush or haze, you can either wipe the area with a strong solvent, like xylene or lacquer thinner, or you can try sanding out the haze and then reapply the topcoat.

Although we spray product all the time in our workshop, with several sprayers ranging from airless to HVLP, we do not consider ourselves to be spray gun experts for all brands.

The most critical part of finishing a piece of furniture happens before you open a can of stain or paint - it starts with the sanding. Sanding is critical to creating a smooth surface. Use the following sanding sequences for new wood:

PAINT

For wood that is going to be painted, use 120-grit, followed by 150-grit.

There is no easy solution to this problem. General Finishes Milk Paint has strong adhesion properties but there are several reasons this finish could fail:

All bright white paint will yellow slightly with time, even without topcoat. You have probably tried to touch up white woodwork in your home after several years and noticed that the new paint is brighter.

But white and light paints can react if clear coated with a waterbased finish; water-based topcoats are reactive and may draw out substances in the wood such as tannins, dyes or unknown substances in existing finishes causing the topcoat to yellow. This is an industry-wide issue and can happen right away, years later or never.

ANSWER: For ideal results, GF recommends applying finish with a spray gun and putting your project on a rotating lazy susan.

Answer: There are several ways to determine whether a surface is dry.

Dry OIL BASED products are no longer tacky and they do not emit a smell.

Dry WATER BASED products no longer feel cool to the touch and a powder will form with light sanding. 

A primer is your best defense under light-colored paint.

Another technique to avoid the slight color change that sometimes occurs when applying topcoat is to add 10-15% of the paint you are using to your topcoat. This technique layers additional coats of color over your piece as well as providing the protection of a topcoat. If you don't like measuring, just add enough paint until you can see a bit of the hue in the topcoat. This method works with a brush or a spray gun.

To maintain the full-strength protection of the topcoat, DO NOT TINT YOUR FINAL COAT of topcoat.
