SILRES® BS 1803

1 of 110 products in this brand
SILRES® BS 1803 is a solvent-free emulsion based on organo-modified silanes and siloxanes. It is specifically designed to act as a water-repellent admixture for semi-dry concrete and other non-load-bearing cement-based building materials, including paving stones and concrete blocks. SILRES® BS 1803 helps to minimize the amount of water absorbed by the concrete or other cement-based materials, thereby enhancing their durability and resistance to moisture-related issues.

Application Details
  • Stir product before use. The recommended admixture range is 0.1 % to 1.0 % of the cement content.
  • A significant reduction in water uptake can be achieved at a concentration of 0.2 %. For post-treatment a 1:4 solution can be recommended to reduce water uptake significantly.
  • When used as an admixture in semi-dry concrete SILRES® BS 1803 produces a matrix that resists water absorption without blocking pores or capillaries.
  • The treated concrete inherently resists intrusion of damaging water and chemicals increasing the service life of the building material. SILRES® BS 1803 prevents or at least reduces efflorescence. A strong water beading effect occurs throughout the whole concrete block.
