Surface Protection

SILRES® BS – Protecting Surfaces against Stains and Graffiti

Natural stone and artificial stone are a popular choice of material due to their unique appearance and the way they feel. But these kinds of stone are particularly prone to staining and weathering. If they remain untreated, the stone absorbs water, oil and other substances very quickly. This causes irreversible stains or other damage. A highly effective and long-lasting way to prevent such damage is to treat surfaces with SILRES® BS, thus preserving the beauty of natural and artificial stone.

Highly Permeable to Water Vapor and Extremely Long-Lasting

SILRES® BS penetrates the pores by means of capillary action and is deposited on the pore walls. These siliconized pores prevent any further capillary effect – without impairing essential water-vapor permeability. What is more, silicone resin coatings last a very long time when some of the coating remains on the surface. This is because these coatings form a long-lasting covalent bond with the substrate and therefore cannot be easily washed off by rain or otherwise removed. At the same time, stains and graffiti are easy to remove.

Permanent Protection for a Variety of Surfaces


  • Minimal absorption of water, oil and dirt
  • Easy-to-clean effect/simple removal of graffiti
  • High water-vapor permeability
  • Possible to accentuate surfaces


  • Dense to porous natural stone, such as marble, travertine and granite
  • Brick/clinker brick
  • Ceramic tiles

Preventive Protection against Stains

SILRES® BS provides easy-to-clean protection against water, oil and dirt, without altering the external appearance of the surface. Unlike film-forming coatings, vapor permeability is not affected – the substrate remains “breathable” and keeps its natural feel.


  • High oil, dirt and water repellency
  • Extremely long-lasting effectiveness
  • Preserves the natural look
  • Non-tacky surface structure
  • No surface sealing


  • Absorbent and dense mineral-based surfaces on:
  • Table tops
  • Window sills
  • Kitchen worktops
  • Internal walls
  • Floors
  • Facades


  • SILRES® BS 38 – solvent-based, but tin-free mixture
  • SILRES® BS 39 – water-based formulation

Suitable for all easy-to-clean protective coatings that do not alter the surface.

Repellency of stains, such as those left by ketchup, mustard, oil, soy sauce and wine (possible to clean surface after 24 hours).

The Two-in-One Solution for Lasting Beauty

SILRES® BS is an ideal way not only to protect surfaces, but also to enhance their appearance. In this way, the natural colors of the substrate surfaces become more vivid and intense – enabling both matt and gloss effects. SILRES® BS 30, a 100% silane/siloxane mixture, is ideal for further surface-enhancing effects.


  • Enhanced visual appearance
  • Enhanced stain resistance
  • Water, oil and dirt repellency
  • Gloss or metallic effect
  • Wet effect possible
  • Paintable
  • Tin-free
  • Low-VOC


Absorbent and dense mineral-based substrates such as marble and granite for:

  • Floors
  • Table tops
  • Window sills
  • Kitchen worktops

Application Method

Easy to apply using a

  • Roller
  • Sponge
  • Brush
  • Pump spray


  • SILRES® BS 30 – 100% silane/siloxane mixture

Permanent Protection against Unwanted Coatings/Graffiti

It is often expensive and unpleasant to remove street art. If a facade is treated with SILRES® BS 710, however, graffiti can be removed easily and cost-effectively. SILRES® BS 710 is a transparent, one-component moisture-curing silicone elastomer concentrate.

Only Water Needed

After application, it forms a permanent coating that makes it possible to remove graffiti using just cold water without any other detergents. Small-scale graffiti can be removed with a wet sponge.

Permanent Effect

There is no need to reapply SILRES® BS 710 after the removal of graffiti. It is a permanent system, unlike most established anti-graffiti systems, which are temporary.


  • Lasting protection
  • Simple removal of graffiti
  • UV-resistant
  • Easy to peel off posters and stickers
  • Breathable film
  • Pigmentable


A variety of substrates such as:

  • Concrete
  • Masonry
  • All kinds of natural stone
  • Wood
  • Coated metal

Application Method

  • Roller
  • Sponge
  • Brush
  • Pump spray
