• Injected damp-proof course (DPC, horizontal barrier) for brick, stone and concrete walls
• Admixture for concrete and other cement based formulations (0.1 - 1.0 % df. based on cement)
Properties/Benefits
As well as durable protection from water-induced damages to masonry TEGOSIVIN® HE 328 and products formulated from it provide:
• Effective protection even in driving rain
• Efflorescence prevention
• Protection against de-icing salts
• Alkali resistance
• A reduction in heat conductivity and thus improved thermal insulation
• A non-tacky finish with a stain release effect
• In most instances no change in surface appearance and virtually no reduction of vapour permeability
• Solvent-free and low VOC

Dosage and Handling
For the production of ready-to-use formulations TEGOSIVIN® HE 328 may be diluted to 5 - 25 % active content depending on the intended use. When used as an admixture dilutions of < 5 % active may be beneficial for cost saving purposes.
For the production of ready-to-use dilutions water (preferably de-mineralised) is added to the emulsion while stirring at low shear. Dilutions have to be protected by adding a suitable preservative (e. g. Acticid MBS from Thor-Chemie). We recommend stirring TEGOSIVIN® HE 328 and formulations made from it prior to use.
Masonry water repellents produced from TEGOSIVIN® HE 328 should be applied by flooding, brushing or rolling. The substrate has to be dry and clean and has to have sufficient porosity. It is recommended to evaluate the required dosage by means of representative test areas prior to the final impregnation. Very dense substrates (e. g. marble) may not be suitable for impregnation with products based on TEGOSIVIN® HE 328.
