Ecological product with a high degree of technological innovation. Mixture of cement, aggregates, additives and 100% recycled polymeric material that give it thermal-acoustic properties superior to those of conventional mortar. The pre-supporting screeds for continuous paving can reach thicknesses of less than 35 mm, providing a completely level, light and seamless surface. It is a product that provides acoustic and thermal insulation as specified in the technical building code.


Additional information

Field of application

  • Surfaces requiring higher than normal thermal and acoustic insulation.
  • Surfaces with a thickness of less than 3.5 cm.
  • Surfaces for lightened structures thanks to its low density.
  • As a final coat, PROSILENCE is compatible with floating parquet, marble, tiles and ceramics. In the case of ceramics, a polishing of the surface layer is necessary.
  • Direct application on the bonded material.


  • High content of recycled material – Environmentally friendly.
  • Low density.
  • Better acoustic and thermal insulation.
  • Controlled dosage – Homogeneity of the product.
  • High flatness.
  • Optimal and fast laying, high daily performance.
  • Good resistance to compression.
  • Optimisation of on-site space – Maximum cleanliness.
  • Safety during application.
  • Provides scores for “eco” buildings according to the Technical Building Code.


Application system

It is supplied by means of a concrete mixer truck on site, and by means of a pumping system it is applied by a professional team of applicators that Molins provides you with.
