Why does my wall go patchy after painting?

Patchiness usually happens if you don't use enough paint, or apply it unevenly. Using a touch more paint, and painting in small sections one at a time, usually does the trick. Also, rolling in a grid fashion will get you an even finish too. But, sometimes, changes in the gloss level leave things patchy.

Clean and dry your brush and roller, or set them aside for a dry, fresh set. Painting with soaking wet brushes guarantees the dilution of your first 15 to 20 minutes worth of painting, and that will make the coat patchy.

Rushing to apply a second coat before the first has thoroughly dried will create this heavy stippled texture. When paint is only dry to the touch a second coat reactivates the first. This effectively reduces the available moisture needed to flow the paint by 50%.

What causes patchy emulsion paint?

The emulsion I have just applied has dried streaky and patchy, why? This is usually caused when the paint hasn't been applied in a uniform/even manner or it hasn't been thoroughly stirred before use.
