Berling recommends various solutions for different paint problems that you may experience in areas you wish to paint. Once you have found a specific problem or issue, these solutions will help you understand, fix the problem and also prevent failures during the painting process. Each different topic illustrates and describes the problem, lists possible causes of the problem and provides one or more solutions.

In addition, indicated products are proposed for the best use and result on your premises. If you need more help, you can always ask us

Discoloration of exterior surfaces

Possible cause:

  • Use of a shade with low resistance to sunlight.
  • Chalking:

A. If the problem does not occur because of chalking (follow recoating directions in case of chalking)
B. There are shades that are non resistant to solar power, resulting in fading shades.

Solutions:

  • The best solution is to choose the correct external shade from Berling’s special colourcard “Exterior”, where you will find shades made without pigments which are not resistant to sunlight.
Peeling

Paint peeling from various surfaces

Possible cause:

  • Wet surface or moisture leakage from compounds which are not well sealed – or not at all.
  • Poor or no surface priming.
  • Bad quality paint that doesn’t have good adhesion properties.
  • Poor preparation of the painting surface.


Solutions:

  • Make sure to insulate the cracks-skirting boards with suitable insulating materials before painting.
  • Surface must be primed.
  • Always use good quality paint with excellent adhesion
  • During repairs, you must:

a) Clean the surface thoroughly using sandpaper or brush
b) Use the appropriate primer
c) Use good quality paint

 

Dust and dirt pick-up on the paint or mold appearance

Possible cause:

  • Withheld moisture
  • Dirt or dust pick-up on the paint
  • Air pollution
  • Poor quality paint


Solutions:

  • Never paint on a wet surface. The plaster must be completely dry otherwise the trapped moisture creates mold. If you must paint under unsuitable weather conditions, then we propose Berling’s unique primer AND paint, Storm Silicon (both are breathable).
  • Wash the entire surface with water and if it remains dirty, then use white spirit.
  • If the problem results from air pollution (with humidity conditions) the problem will unfortunately reappear.
Chalking

Appearance of fine powder on the painted surface. Usually on exterior surfaces.

Possible cause:

  • Poor or low quality paint.
  • Excessive alkalinity in construction materials (plaster-cement)


Solutions:

  • Remove the powder from the surface using sandpaper or brush.
  • Pour plenty of water to remove any residue.
  • Prime the surface using Super Primer
  • Paint again with 2 coatings using a very good quality paint (Monostop, Acrylux, SuperStorm) for exterior use.
Creation of color cracks in the form of “crackle”

Possible cause:

  • Final coat application to the primer, which is not well dried.
  • Application on rubber or asphalt/cement undercoat
  • Paint application under extreme weather conditions (very hot – too wet – very low temperatures).


Solutions:

  • It is essential that the primer has completely dried.
  • If the surface is elastomeric or asphalt/cement, prime first with Super Primer or Fixateur
  • Never apply paint under extreme weather conditions.
Paint dripping during application

The paint dripping phenomenon that takes place immediately after application, results in an uneven appearance of the final coating.

Possible cause:

This problem usually occurs in oil paints and varnishes. This is because:

  • You have applied paint, leaving too much of it on the surface without spreading it.
  • The paint has been diluted too much.
  • Paint conditions are affected by high moisture.


Solutions:

  • When applying, make sure to spread evenly the appropriate paint quantity by working the roller or the brush horizontally and vertically.
  • Always follow our dilution directions.
  • Do not apply under inappropriate weather conditions.
Stain appearance on the painted surface

Possible cause:

This problem typically occurs on repainted surfaces:

1. These stains come from:

  • Fumed surfaces (nicotine)
  • Very dirty surfaces (usually over radiators or around canvasses)
  • From oily residues on the surface
  • Alkalis that come from the plaster


Solutions:

  • The surface should be primed with the appropriate primer
  • There are special primers that hold up nicotine stains, such as Aquasil.
  • We recommend Super Primer that locks up the blackness, stains and alkalis.
Dull or shiny spots on painted surface

Possible cause:

  • Poor surface priming
  • Poor paint application with different hiding applications and uneven paint thickness
  • Excessive color thinning


Solutions:

  • New unpainted surfaces should be primed carefully.
  • Make sure that during paint application, the junction point is not completely dry, so we have an additional coating as a result (at that point).
  • Stir well and follow the dilution instructions as mentioned.
When the surface is washed with a sponge or cloth, the paint faints

Possible cause:

  • Low-quality paint.
  • High strength applied during rubbing.
  • Absence of sufficient drying time after paint application.


Solutions:

  • Use good quality emulsion paints such as Petite Mat, Petite Mat Satin, Eco Emulsion, Eco Leader, Yes.
  • Satin or glossy emulsion paints have much higher resistance to washing. In places where frequent washing is required, prefer using satin or glossy emulsion paints.
  • Allow sufficient time for complete drying, at least a week.
Low hiding power

Unsatisfactory paint hiding for good surface application coverage (in two coatings).

Possible causes:

  • Possible high surface absorbency.
  • Possible high paint dilution.
  • Stains and blackness or ink strokes which appear after 2 coatings.
  • Low-quality color
  • Poor quality or inappropriate roller
  • Shades of our choice, that have a low hiding power by the manufacturer.


Solutions:

  • If the surface to be painted is very absorbent , it must be first primed with Berling Emulsion Primer White or Berling Acrylic primer White (for external surfaces) or solvent based primer Berling Super Primer.
  • Always follow the manufacturer’s instructions.
  • Prime the surface with the appropriate primer or apply the same shade paint as a third coating
  • Have you chosen low quality paint, which is equally followed by a low price? We recommend good quality paint.
  • When painting with emulsion paints, always use roller with short hair.
  • It is well known that some shades do not have good hiding power. In this case, you either tint the primer approximately in the same shade and you apply at least two coatings, or you apply two or three coatings on top of the original two applications.
Creation of different color shade in the corners and cuts

Possible causes:

If there is no proven paint quality problem, then:

  • The problem occurs when we have first painted the main room with a roller and then the edges and corners with a brush (this is wrong). You should do it the other way round.
  • Do not “cut” the entire room. Paint on smaller areas so the surface on which you have made the “cutting”, remains wet. After that and as long as the “cutting” is still wet, you can paint the surface by using a roller.
Mold

Grey-black spots, smudges, patches or stains on the surface.

Possible causes:

Mold is created by moisture originating from indoors, especially in hot unventilated areas. Vapors which are created from various reasons (bathrooms, kitchens, etc.) become humidified and create an environment where fungi (mold) grows.

Solutions:

  • With a water and bleach mixture solution (1:4), clean the mold as much as possible.
  • Then apply the special anti-mould emulsion paint Super Best in two coatings
  • Berling’s SuperBest is especially designed to prevent fungal growth on the surface.
What can be done when on interior surfaces painted with an emulsion puttied areas show through?

The paint that has been used is either bad quality, or whitewash, water based paint, or the surface has not been coated with the suitable primer. The surface must be treated with the waterborne primer Aquafix, or the solvent based primer Fixateur. Two coats of the ecological paint Petite or Eco Emulsion should follow.

What can be done when interior surfaces painted with an emulsion leave paint residue on one’s hand?

The paint that has been used is either bad quality, or whitewash, water based paint, or the surface has not been coated with the suitable primer. The surface must be treated with the waterborne primer Aquafix, or the solvent based primer Fixateur. Two coats of the ecological paint Petite or Eco Emulsion should follow.

What can be done when interior surfaces painted with an emulsion leave paint residue when wiped with a cloth?

The paint that has been used is either bad quality, or whitewash, water based paint, or glue. The surface must be treated with the waterborne primer Aquafix, or the solvent based primer Fixateur. Two coats of the ecological paints Petite or Eco Emulsion should follow. Allow the surface to dry thoroughly, before washing it. The surface should be washed with a sponge or rag, and mild detergent.
