Sagging
Read MoreDownward “drooping” movement of the paint film immediately after application, resulting in an uneven coating. Possible causes: Application of a heavy coat of paint. Application in excessively humid and/or cool conditions. Application of overthinned paint. Airless spraying with the gun...
Roller spattering
Read MoreTendency of a roller to throw off small droplets of paint during application. Possible causes: Use of exterior paint on an interior surface. Use of lower grades of latex paints. Solution: Higher quality paints are formulated to minimize spattering. Using...
Roller marks/stippling
Read MoreUnintentional textured pattern left in the paint by the roller. Possible causes: Use of incorrect roller cover. Use of lower grades of paint. Use of low quality roller. Use of incorrect rolling technique. Solution: Use the proper roller cover; avoid...
Surfactant leaching
Read MoreConcentration of water-soluble ingredients on latex paint, creating a blotchy, sometimes glossy appearance, often with a tan or brownish cast. More likely with tinted paints than with white or factory-coloured paints. Possible causes: Painting in cool, humid conditions or just...
Wrinkling
Read MoreA rough, crinkled paint surface occurring when paint forms a “skin.” Possible causes: Paint applied too thickly (more likely when using alkyd or oil-based paints). Painting a hot surface or in very hot weather. Exposure of uncured paint to rain,...
Poor stain resistance
Read MoreFailure of the paint to resist absorption of dirt and stains. Possible causes: Use of lower quality paint that is porous in nature. Application of paint to un-primed substrate. Solution: Higher quality latex paints contain more binder, which helps prevent...
Poor sheen uniformity
Read MoreShiny spots or dull spots (also known as “flashing”) on a painted surface; uneven gloss. Possible causes: Uneven spread rate. Failure to properly prime a porous surface, or surface with varying degrees of porosity. Poor application resulting in lapping (see...
Poor scrub resistance
Read MoreWearing away or removal of the paint film when scrubbed with a brush, sponge, or cloth. Possible causes: Choosing the wrong sheen for the area. Use of a lower quality paint. Use of an overly aggressive scrub medium (see burnishing)....
Mud cracking
Read MoreDeep, irregular cracks resembling dried mud in dry paint film. Possible causes: Paint is applied too thickly, usually over a porous surface. Paint is applied too thickly, to improve inherent poor hiding (coverage) of a lower quality paint. Paint is...
