The paint appears to have dripped down the wall

Εξωτερικά σε διάφορα σημεία έχουν δημιουργηθεί τρεξίματα με τη μορφή κάθετων γραμμών. Πού οφείλεται;
  • The paint was applied in conditions of high humidity (fog, dew, frost, etc.).
  • It rained shortly after the painting was completed.
  • Rinse the surface (if possible) with water and gently rub with a cloth or sponge as soon as possible after the problem occurs.
  • Leave it to self-wash over time.
