Polymer based Lucas #1900 Water-Based Clear Sealant is an elastomeric water-based coating intended for waterproofing fiberglass roof panels and translucent skylights.
Lucas #1900 is based on 100% acrylic co-polymers. The formula is non-yellowing and will develop a tackfree finish when fully cured.
Surface to be coated must be dry and free of dirt or corrosion particles. Mechanically mix product before using. Avoid entraining air in the product. All seams, fasteners and penetrations should be sealed with #1500 Acrylic Mastic. Apply in two coats of 1 gallon per one hundred square feet each. For best results, apply coating in one direction with the slope of the roof.
When applied to areas that retain water more than 48 hours service life will be severely diminished and adhesion failure can be expected.
