SILRES® BS 1803
SILRES® BS 1803 is a solvent-free emulsion based on organo-modified silanes and siloxanes.
SILRES® BS 1803 can be used as water repelling admixture for semi-dry concrete and other non-load-bearing cement based building materials (e.g. paving stones, concrete blocks)
- greatly reduces water absorption
- very good water beading
- protection against de-icing salts
- efflorescence reduction
- water vapor permeable

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.
