paint over water stains

Water stains on the wall or ceiling can be painted over, but only when the ceiling / wall is completely dry. Read on to find out what else you should pay attention to when painting over water stains.

What to do beforehand

Water stains are no coincidence: The source of moisture must be permanently removed, otherwise painting over the water stain is completely pointless. Then you should let the wall dry out completely. If the damp area is in a heatable room, it is advisable to turn up the heating for a few days, in summer you should simply keep the window open when the weather is good. An electronic heater that is placed directly in front of the wall can also be of great help.

Instructions for successfully painting over water stains

  • spatula
  • Container for mixing the filler (€ 4.25 at Amazon *)
  • Paint roller
  • vacuum cleaner
  • Filler (if necessary)
  • Isolation Ground
  • Wall paint

1. Remove salt crystals and other

Complets moisture from a wall, creating small salt crystals when drying on the surface. In addition, wallpaper and wall paint dissolves. You can not simply paint the dissolved wallpaper! This must first be removed together with the salt crystals. To do this, scramble with a spatula over the affected area and remove loose color and wallpaper residues.

Then suck the stain with a vacuum cleaner.

If any adjoining sockets, door or window frames or other surfaces stick with crepe tape.

2. Isolate

Then use the color roller to wear a layer of insulation based on the stain. This covers the stain reliably. Depending on the degree of pollution, you should apply two or three layers insulation reason.

Then let the color dry three to four hours (observe the manufacturer's instructions!To).

3. Filling

If the scraping off has created bumps, these are removed next. To do this, stir the filler according to the manufacturer's instructions (or use ready-made, liquid filler) and apply it thinly to the wall / ceiling with the help of the spatula.

Make sure that you only fill in bumps and not put too much mass on the wall, so that new bumps appear instead!

Let the filler dry completely (observe the drying times on the packaging!).

4th. Paint over

Finally comes the new coat of paint. To avoid transitions, you should repaint the entire wall. When buying wall paint, keep in mind: the higher the quality the paint, the better the result and the fewer coats of paint are necessary. So go ahead and spend a few more euros.
