Liquid Rubber Metalsafe Sealant is a sealant that is easily brushed on and cures into a waterproof membrane. It can be used in many applications where you need to create a watertight seal. Metal roofs, ponds, lightly rusted areas, and more. Use Liquid Rubber Seam Tape or Liquid Rubber Geo-Textile to bridge seams, joints, vents, protrusions to create a long lasting repair or rejuvenation. Apply when temperature is above 5C/41F. Apply to a dry surface, free of anything that would hinder adhesion. Typically cures within 24-48 hours. Do not freeze. Store in a warm area. Do not apply in wet conditions or if rain is forecasted within 24 hours. Not meant as a constant walking surface. Coverage: Vertical Surfaces - Apply a minimum final thickness of 1 gallon/30 sq ft (2.8 sq m). It should require around 2-3 heavy coats to achieve a 30 mil. (0.76mm) (DFT) membrane. Flat/Ponding Surfaces - Apply a minimum final thickness of 1 gallon/15 sq ft (1.4 sq m). It should require around 4-5 heavy coats to achieve a 60-80 mil. (1.5-2mm) (DFT) membrane. Apply next coat when dry to touch and nothing is wet underneath; tacky is okay. Generally, 12-24 hours between heavy coats. Amounts vary depending on surface roughness. Use all material up to achieve a long lasting membrane. Avoid hot, direct, intense sunlight during application. Remove painters tape while still wet. Membrane will turn brown in ponding situations due to surfactants. Will dissipate over time as the water cycles and cleans. Clean Up: Use soap and water or mineral oil to clean skin.
