There are many types of paint failures but the causes for different paint failures are very common i.e. moisture, poor surface preparation etc. Given below are some easy remedies for different paint failures.
Moisture is the main cause of blistering. To prevent blistering, avoid painting on a sunny day or under direct sunlight. When blistering goes down to the substrate level, remove the blister by scrapping, then sand the surface. surface preparation is an essential before priming and repainting.
Leaching occurs in a damn area due to moisture. To avoid leaching, painting should be done on a completely dry and prepped surface. If the leaching occurs in a first few days after painting is resin by water. It is a common problem and it doesn’t affect the durability of paint.
Improper drying of paint coating results into wrinkling. Thorough drying of a paint coating prevents wrinkling. Scraping of substrate removes wrinkling and sanding smooth up the then the surface. Priming is the next step after surface preparation. Repainting is later stepping when the primer dries down completely.
Yellowing occurs due to oxidation and oxidation in solvent based paints is a natural phenomenon. Choosing a water based acrylic paint is a better idea to prevent the yellowing. Yellowing takes place in damp areas or the areas without any exposure to sunlight. If the yellowed paint coating comes under direct sunlight again, the color changed back to previous overtime.
Poor color hiding
Poor color hiding is a problem related with quality of paint. Primer hides the underlying coating or original wall surface if it is darker than the paint color. Using better quality paint or quality painting tools are better for hiding underlying surface.
Poor sheen uniformity
Uneven spreading of paint results in poor uniformity of coating.Priming gives Homogeneity to wall surface before application of an upper layer of paint coating. Priming fills the uneven cracks or hole on the surface. Application of an additional coat is essential for unprimed surfaces.
Use of low-quality paint results into formation of small powder or chalky residue on a wall surface. A wire brush or a water wash is helpful in removing the chalky residue. If chalk residue is not present then priming is not necessary. Use of high-quality exterior paint avoids future chalking even on the surface without priming.
Use of interior paint on exterior walks or lower quality paint results in premature lightning o the paint color. Fading is a result of chalking. Removal of as much chalk residue as possible avoids fading. High-quality exterior paints should be used for repainting.
