W. R. Meadows recently introduced Peneseal W/B, which limits the intrusion of moisture and chlorides into concrete surfaces. Peneseal W/B is a water-based, VOC-compliant, penetrating concrete sealing compound for exterior concrete surfaces. The proprietary blend of silane and siloxane in Peneseal W/B penetrates deep into the pores of the concrete to help protect it from scaling and freeze-thaw damage caused by de-icing chemicals. Transparent and nonstaining, Peneseal W/B reduces entrapment of dirt particles and other contaminants that cause discoloration. Surfaces treated with Peneseal W/B will also be resistant to staining from oils, fuels and common chemicals. In addition, Peneseal W/B contributes to Materials and Resources LEED credits.
