CHEMIACRYL Acrylic Sealant is an is an acrylic-based elastic sealant that protects against dust and water.



  • Easy application
  • Over-paintable
  • Can be easily smoothed and levelled out
  • Form permanently water-repellent layer after curing
  • Keeps flexibility quite a while after curing
  • Good weathering and water resistance


The product hardens by dehydration (dry by water loss), so it should be protected from water until the joints form a resistant and hard coat.
Factors such as high humidity, low temperatures and too thick joints can significantly delay coating formation and drying.
In outdoor applications, protect the dry product from rain. Avoid permanent contact with water and moisture.
During the drying process, the colour of the sealant may vary slightly.
The product is compatible with various paint systems, however, a previous test is recommended.
Before painting, the sealant must be completely dry.
Do not apply when in contact with surfaces that may release bitumen, tar or plasticizers.
