SILRES® BS 1803 A

1 of 110 products in this brand
SILRES® BS 1803 A is a stable and VOC-compliant silicone emulsion with a 60% active content. It is specifically designed to reduce water uptake and create visual beading on concrete substrates while allowing the pores and capillaries to remain unblocked. This product is particularly effective when it comes to preventing water uptake and promoting beads, even at very low addition levels. One of the main applications of SILRES® BS 1803 A is as an admixture for non-load bearing cement-based formulated products, including precast products, blocks, and pavers. By incorporating this emulsion into the formulation, the resulting products gain enhanced waterproofing properties and resistance to water penetration. Furthermore, SILRES® BS 1803 A can also be used as a topical sealer for post-treatment of cement-based formulated products.

Applications
  • Concrete Admixtures
  • Concrete Protection
Application Details
  • Use of SILRES BS 1803 A as a waterproofing concrete admixture in accordance with ASTM C 494: SILRES BS 1803 A can be diluted in the mix water, added simultaneously with the mix water or post added to the wet concrete blend. The recommended admixture range is 0.2-1.0% based on cement (3 oz. to 16 oz./cwt).
  • We recommend testing compatibility with other concrete admixtures separately. Use of SILRES® BS 1803 A as a topical waterproofing sealer (post-treatment): Recommended dilution is a 1:4 ratio of SILRES® BS 1803 A to water (by weight).
  • Recommended application rate is 125 ft² per gallon.
  • Product may be applied with a roller, brush or low pressure sprayer. Note:Do not atomize this product.

Processing

  • Thoroughly mix SILRES BS 1803 A prior to use to insure that the emulsion is homogeneous.
  • Tap water is acceptable for blending. Due to the chemical variables in tap water and in concrete formulas it is recommended that samples be tested for water repellency, beading and other performance parameters prior to commercial use.
  • Mixing time should be adjusted to insure thorough distribution of all components including SILRES® BS 1803 A.
  • Depending on curing conditions, water repellency can be seen after 24 hours and maximum water repellency is realized in about 72 hours. Beading generally improves over time however best results are noticed after 28 days.
