Paint that was applied to the walls sometimes run into various problems in the future. The causes include the lack of proper application techniques, paint quality is not good to use, or less than the maximum surface preparation.
Painting problems are frequent and common among which are:
Chalking (calcification), a layer of paint film is damaged due to the influence of alkali salts attack (commonly seen in the new wall painting) or the influence of sunlight (going on outside the walls of the room). Dilution so that the paint is too thin the paint film can not be formed.
Water Spot(such as wet spots), use of which has not plamur perfectly dry and then given a coat of paint, then the remains of plamir water is trapped between two layers of paint plamur and thus causing wet spots like.
Saponification,alkali attack on adhesives made from layers of paint that contains oil as alkyd gloss. Alkali and oil will react chemically called saponification which gives the final results such as soap and a soft lead paint layers and form a sticky blob.
Drying Trouble(hard dry), the painting is done in poor weather such as low temperature, hazy and humid, the painting is done on surfaces that contain wax-like material for polishes, oils or dust, painting with alkyd enamel paint on the type of wood surface been given a camphor layer of shellac material, the use of a diluent which does not correspond to the type of paint used.
Stainning (spots like the island), use wall paint from wood, because wood or resin-containing media was still unfinished in the preparation of the material out. The sap that comes out trapped under layers of paint and form patches like islands.
