WEBERTEC FILLER

Webertec Filler is a cement and powder polymer-based filling and repair mortar designed for interior and exterior applications. It is developed to level uneven surfaces and create a smooth, durable substrate before painting and coating applications. The product provides reliable repair performance with high adhesion, mechanical strength, and moisture resistance.

According to the technical datasheet, it can be applied in thicknesses ranging from 1–10 mm, with a maximum recommended thickness of 5 mm per coat.

Areas of Use

  • Filling and surface repair on interior and exterior walls
  • Covering imperfections on wall and ceiling surfaces
  • Preparing smooth and solid substrates before painting and coating
  • Creating moisture- and humidity-resistant surfaces
  • Levelling rough surfaces with its filling structure
