W. R. Meadows Inc. has launched Intraguard, a water-based, penetrating concrete sealing compound for exterior concrete surfaces specifically designed to limit the intrusion of moisture and chlorides into concrete surfaces. Its proprietary blend of silane and siloxane penetrates deep into the pores of the concrete to help protect it from scaling caused by deicing salts. The product is designed to provide lasting protection from de-icing chemicals and moisture intrusion. Surfaces treated with Intraguard will also be resistant to staining from oils, fuels and common chemicals. Intraguard also reduces the entrapment of dirt particles and other contaminants that cause discoloration and inhibits soiling, protects against efflorescence and rust staining, and is water based and VOC compliant.
