Special features
- excellent water repellency: reducing cracking, spalling, freeze / thaw damage, chemical degradation, efflorescence and dirt pick-up
- excellent beading for improved aesthetics
- low VOC emissions during curing
- minimizes darkening effects, maintaining the original substrates’ appearance
- minimal effect on adhesion of topcoats to the mineral substrate, improving the service life of the paint
- lengthens substrate life, reducing maintenance costs
Application
- Thoroughly mix SILRES® BS 1803 US prior to use to ensure 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 US.
- 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.
Use of SILRES® BS 1803 US as a waterproofing concrete admixture in accordance with ASTM C 494: SILRES® BS 1803 US can be diluted in the mix water, added simultaneously with the mix water or preferable after 75% of mix water is added. 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 US as a topical waterproofing sealer (post-treatment): Recommended dilution is a 1:4 ratio of SILRES® BS 1803 US to water (by weight).
- Recommended application rate is 125 ft² per gallon.
- Product may be applied with a roller, brush or low pressure sprayer. DO NOT ATOMIZE THIS PRODUCT.
