SILRES® BS 34 A is a stable, low VOC silicone and organic polymer containing water based emulsion. When applied to a surface it forms a stable, penetrating water repellent for enhancing a wide variety of porous mineral substrates including concrete, natural and artificial stone and unglazed ceramic tile.

SILRES® BS 34 A is not recommended for below grade applications where hydrostatic pressure can be significant.

  • Enhances the features of the substrate providing a vibrant appearance
  • Repels water, hindering penetration, maintaining a consistent appearance
  • Beads liquids
  • Very low VOC
  • Physically and chemically bonds to substrates increasing the service life, making cleaning easier, thereby reducing maintenance costs
  • Improved UV stability
  • Suitable for interior or exterior decorative stone and concrete projects


The "Best use before end date" of each batch is shown on the Certificate of Analysis.
