Phenomenon: The paint film surface is dry, wrinkled, grainy, does not create a continuous surface.

Reason:
– Applying too heavy paint, especially for Alkyd or oil-based paints)
– Construction in hot or too cold weather causes the coating outside to dry too quickly compared to the inner layer.
– Due to the high humidity in the air, it affects the drying process of paint film.
– Do not comply with the time the paint layer is removed, the inside layer is not dry already painted outside layer.
– Paint on the surface of impurities.

Solution: Remove the paint, clean the surface. When using primer, allow this layer to dry completely before applying the coating (avoid painting in extremely high temperature and humidity conditions).

Phenomenon: There are cracks on the paint film surface.

Reason:
– Use paint with low adhesion and durability.
– Paint is too thin or too thick
– No good surface treatment, or non-primed wood surface.
– Use Alkyd paint that is too hard or too brittle.

Solution: Use an effervescent brush and a high-iron brush to remove all paint, sanding surfaces and corners. For wood, use primer before recoating. Use high quality paint.

Phenomenon: The paint film is not smooth and flat due to the foam particles and holes caused by the foam.

Reason:
– Stir the paint bucket evenly.
– Use low quality paint.
– Roll the paint too fast
– Incorrect use of the roller (incorrect yarn length).
– Rolling excess paint.
– Paint has a high gloss on the rough surface.

Solution: All paints during the construction will foam, but the paint quality, when the surface is still wet, the foam has broken, giving the paint film a good flow. Avoid over-rolling or over-use paint. Using a semi-gloss or semi-gloss paint with a short-fiber roller, roll primer over a rough surface before painting. Sand the rough surface before rolling repainted.

Phenomenon: the paint film is green or brown, black spots.

Reason:
– Occurs in places with favorable conditions for the development of moss: moist, warm (bathroom, kitchen, washing room) …
– Due to the use of Alkyd paint or oil-based paint or water-based paint of low quality.
– For wood surface: the primer does not meet the quality before painting.
– Paint on the surface of moss that has not been carefully treated.

Solution:
Check by using 1 drop of bleach on the mossy area (blob), if the spots are faded. Scrub the entire surface to remove mold and mildew with a bleach solution. When using this solution, wear rubber gloves and eye protection. Use high quality water paint. These paints have more anti-moss properties than low quality paints. Clean the surface with a cleaning solution if necessary. Install a fan in a place with high humidity.

Phenomenon: The concentration of active substances on the surface of water paint in places with high humidity. It has a light brown stain and sometimes looks like soap or sticky mucus.

Reason: All water paints suffer from this phenomenon when painting in places with high humidity, especially in the ceiling.

Solution: Use soap to wash the problem area and when painting the bathroom, let the paint film dry completely before using water. Remove all stains before repainting.

Phenomenon: The paint film is damaged by absorbent dirt.

Reason: Use low-quality paint or paint on non-primed surfaces.

Solution: Using high-quality water paint, this paint has a high content of film-making substances, dirt is difficult to penetrate into the paint film, facilitating easy cleaning. It is recommended to use primer to create paint film with maximum thickness to prevent contamination
