Stonat Protect Plus is a two-component matte PU varnish in an aqueous phase, for coatings in the Stonat range, forming a permanent barrier resistant to impacts, dirt as well as chemical agents and bad weather. It can be applied indoors and outdoors. It is particularly suitable for showers, worktops and furniture. It is ideal for protecting your Stonat coatings and guarantees their durability over time.

The use of this varnish allows:

  • Very good adhesion on Stonat compound for Lime and clay
  • Does not yellow
  • Its alkaline, dirt, dust and UV resistance
  • Its resistance to chemical attacks
  • Its water vapor permeability (Sd 0.295(m)), compatible with building physics, particularly eco-construction solutions
