Product details



NANO-BAU GRESS PROTECT impregnation is an innovative agent based on silicon nanoparticles intended to protect matte stoneware and terracotta tiles against dirt and stains. The unique formula of the preparation protects impregnated stone surfaces against oil stains, food fat, mustard, wine and other foodstuffs. Suitable for indoor and outdoor use. It does not create a layer of varnish and does not darken the surface. Perfect for protecting stoneware against limescale deposits in bathrooms.

Wear: 10 to 20 ml/m2


  • Floors and terraces
  • Floors and building finishes made of terracotta and stoneware
  • Shower cabin finishes
  • Glazed ceramic tile
  • Clinker and glazed brick
  • Ceramic pots
  • Lastrico


  • excellent protection against stains and dirt
  • protects against oil, ketchup, mustard, wine, coffee, cola and fats
  • hydrophobic and protects against limescale deposits
  • does not change the slip, does not make the surface shiny
  • protects against the harmful effects of weather conditions,


The effect of the impregnation on most surfaces is about 1 year, but in places used to a greater extent, there may be a need to improve the impregnation after about 6 months. Thanks to surface protection with NANO-BAU preparations, they become exceptionally easy to clean. Most of the dirt is washed off by rainfall, and periodic cleaning is recommended using pressurized water.

 We use the impregnation to protect:

  • mat stoneware and terracotta
  • travertine, basalt, onyx
  • glazed tile
  • clinker and glazed brick
  • slate, quartzite,
  • stone conglomerates, terrazzo

application method: spraying, brush painting, immersion

wear: depending on the type of surface from 10 to 20 ml/m²

Application method:

  1. Before impregnation, the surface should be clean and dry. All types of dirt should be removed (algae, mosses, lichens, as well as stains from various types of liquids, etc.). Elements and surfaces that will not be impregnated and are in the immediate vicinity should be protected, for example, with a protective foil.
  2. NANO-BAU GRESS PROTECT impregnation is applied without dilution with a garden sprinkler or HVLP gun, you can also use a roller or brush to apply it, or immerse objects in the preparation.
  3. Apply a thin layer of impregnation and then polish the surface with a paper towel or clean cloth.
  4. Leave to dry. Protect against precipitation for approx. 4 hours.


Depending on the degree and method of use from 6 to 12 months.

NANO-BAU GRESS PROTECT impregnation for stoneware and terracotta is a specialized product that offers many benefits. Here are some reasons why you should use it:

  • Protection against stains and dirt: NANO-BAU GRESS PROTECT impregnation creates an invisible, protective coating on the surface of stoneware and terracotta. It protects against stains, dirt and other substances, which makes it easier to keep clean and prolongs the aesthetics of the surface.
  • Moisture resistance: NANO-BAU GRESS PROTECT impregnation creates a hydrophobic barrier that repels water and moisture. Thanks to this, stoneware and terracotta surfaces are more resistant to stains caused by barbecue grease or rainfall.
  • Easy to clean: Thanks to impregnation, surfaces become easier to clean. Dirt does not penetrate deep into the substrate, and ordinary cleaning agents are more effective in removing dirt.
  • Long-lasting color protection: NANO-BAU GRESS PROTECT impregnation protects against fading and loss of color on stoneware and terracotta surfaces. They retain their original appearance for longer, even when exposed to UV radiation.
  • Ease of application: NANO-BAU GRESS PROTECT impregnation is easy to use and can be applied independently. Usually, it is enough to apply it to a clean and dry surface using a cloth, roller or spray and then polish it with a microfiber cloth.

It is worth using NANO-BAU GRESS PROTECT impregnation for stoneware and terracotta to ensure protection, ease of cleaning and attractiveness of the surface.
