Royston® 120-29 Edge Sealer

Royston® 120-29 Edge Sealer is a single component, cold applied, high viscosity black rubberized asphalt sealant. Designed to create a watertight seal in between masonry and/or waterproofing materials, 120-29 Edge Sealer is commonly used as the perimeter and joint sealant with our Rosphalt® line of asphalt additives. Additional applications include use as a joint adhesion promoter between sections of traditional asphalt pavement and as cold applied crack sealer for asphalt pavements. Locations include curb lines, areas around drains & scuppers, along expansion dams or any other locations that are physically difficult to seal. Royston® 120-29 Edge Sealer adheres easily to dry concrete and asphalt base surfaces such as Rosphalt® , Rosphalt® LT and traditional HMA overlays.
