Profile: R. M. Lucas Co. offers a full line of coatings and mastics for the professional roofing contractor. Our aluminum roof coatings are an effective reflective surfacing for asphalt B.U.R. & both SBS and APP modified bitumen roofs. Our aluminum roof coatings consist of bright reflective aluminum flakes in a bituminous vehicle with various modifiers. Our solvent-based elastomeric coating provides moisture resistance and offers lower water vapor transition than water-based elastomeric coatings. This allows application in roof areas that retain ponding water. Highly impermeable coatings prevent penetration by moisture & oxygen and ingredients necessary for rust development & growth.
