Strip paint completely using chemical stripper or a hot air gun (Image 2). Prominent brush marks are caused by poor application technique (Image 1). If using a natural wood finish, take care to apply stain with the grain, keeping a wet edge at all times.
Sand the area to remove any paint ridges created by roller edge trails (Image 2).
Recoat the area using as many coats of paint necessary to match the surface (Image 3).
This problem sometimes occurs when filled areas are not primed before painting.
View photo gallery instructions for this project Drips are caused by poor technique — usually overloading the brush during application.
Drips may look unsightly but can be easily removed (Image 1). Stains are caused by smoke damage or not properly priming before painting. You can also treat stains caused by mildew this way, provided the cause of the problem has been fixed.
Use a scraper to scrape back the paint drips (Image 2). Clean the area thoroughly with TSP, then allow the surface to dry completely (Image 1).
Apply stain blocker or oil-based undercoat over the stain (Image 2).
Allow the stain blocker or undercoat to dry, then recoat with spare topcoat (Image 3).
Rough or gritty finishes are a result of poor preparation or impurities introduced into the paint during application. This effect is created by painting coats too quickly, and not allowing adequate drying time.
