A ready to use, water based silane/siloxane water repellent. Designed for use on concrete and masonry surfaces, Siloxane PD penetrates more deeply than conventional water or solvent based water repellents. Low odour and alkaline stable, Siloxane PD is ideal for field or in plant application to colour sensitive concrete, GFRC, most masonry and stucco surfaces. Application equipment, window glass and areas affected from overspray are easily cleaned with soap and water.
