PAINTING FAILURE

Premium paint with outstanding raw materials comes from the renowned worldwide paint producer. Before sending it to the market, the products have undergone a series of researches and tests to make sure that there should be no mistakes or failures in the painting process.

If any information and techniques for painting is applied properly as suggested, no mistakes will occur.
BLISTERING
Premium paint has strong bonding and plastic layers, therefore play a great role in preventing water or solvent underneath the paint from arising to the top. This, as well as starting a painting process on a damp surface may cause lesser adhesive power, which can also encourage blistering on the wall's surface.

Solvent may stay underneath a surface when the painting process is done within a thick layer and been exposed directly under the sunlight. The upper layer will dry up fast, while the lower layer will probably occupy too much solvent on the inside. This solvent may be trapped underneath a dry layer and force it to blister.
Prevention:
  1. The recently cleansed wall surface (either by clean water or rain) should be dried thoroughly.
  2. The timeline between each layer should definitely be based on the provided technical data. Each layer needs to be as thin in shape as possible to encourage a perfect dry out.
  3. Avoid doing any painting works while in bad climate (rainy, foggy, or humid) or on surface with direct exposure to sunlight.
Reparation:
When blistering occurs in many spots, the paint surface has to be entirely cleansed and scrubbed. Wipe the surface and use foundation when needed, before finally applying the final paint coating. Otherwise, when blistering seldom happens, the reparation should only be done as needed on the problematic areas.
WATER SPOT
The case is almost similar to blistering, only here the paint layer has been properly glued therefore water or solvent trapped underneath the layer may create a wet look accent to the surface. Other reason is due to lack of time needed to dry off the surface while painting by using plaster material. Remains of the plaster migrated to the upper layer, trapped underneath, therefore the surface may look as if it is wet.
Prevention:
  1. Similar to blistering.
  2. Plaster is not recommended to polish the wall?s surface.
Reparation:
Scrub the whole surface to widen the pores; allowing water, solvent and material to vapour easily. When mildew has grown widely on a wet area, wash it down with chlorine and wipe it off with a damp cloth. When needed, apply one layer of Wall Sealer before finally adding the finishing.
FLAKING
Flaking generally happens due to these possible causes:
  1. Painting is done on an old painting surface, therefore may also eliminate the adhesive power of the paint.
  2. Painting is done on an oily and dirty surface.
  3. Using low quality plaster that has no adhesive power, and in result when given a final coating it will instantly remove the plaster.
  4. When painting using high quality paint on an old low quality painting surface with less adhesive strength, the old surface will come out and rise on top.
  5. The foundation does not applicable for use with the final paint coating.
Prevention:
  1. Paint surface has to be free from water, humidity, and dirt.
  2. Remove old painting surface, either broken or of low quality product.
  3. Avoid using plaster all over the surface, especially for exterior.
  4. Only use the type of foundation as recommended in conducting such painting project.
Reparation:
Scrub the old painting surface to the very end, and clean the surface. Apply foundation before the final coating whenever necessary.
CRACKS ON BUILDING WALL
Prevention:
  1. Apply Alcaplast-Alcabond + water with ratio of 5:1:2 to seal and cover the cracks on wall to create a smooth surface.
  2. Add Wall Sealer (Water Based) ± 1 layer as primer before painting the top coat.
  3. Paint the top coat.
