WEBAC_® 5611: highly resistant acrylate dispersion for sealing surfaces against pressing water

WEBAC_® 5611 is a highly resistant and sprayable bituminous acrylate dispersion. It is designed for sealing surfaces against pressing water. WEBAC_® 5611 can be used in civil engineering, foundation engineering, tunneling and construction engineering, and the sealing system is especially suited for use in monument conservation. 

WEBAC_® 5611 is an active sealing system; separately available Portland cement is added to the bitumen modified acrylate dispersion. The two components interact chemically and physically after mixing. They are perfectly matched as regards cross-linking and film formation of the dispersion on the one hand and hydration of the cement on the other hand.
 

WEBAC_® 5611 offers reliable protection from salts detrimental to the building structure

The excellent properties of WEBAC_® 5611 are only obtained if the specified mixing ratio of 1 : 0.8 parts of cement is complied with. Thanks to the hydrophobizing effect of its bitumen content WEBAC_® 5611 provides reliable protection from damage caused by salts detrimental to the building structure (salt resistance). WEBAC_® 5611 can be used without undercoat or primer. It is recommended to apply a priming coat of WEBAC_® 5611 without added cement before use. WEBAC_® 5611 is usually applied by roller or wide paint brush but the acrylate dispersion is also suitable for spraying.
