Liquid Rubber Color Waterproof Sealant - Elastomeric Roofing Coating for Flat or Slope Roofs & Foundations - DIY Paint & Leak Repair Membrane Compatible with Metal & Concrete - White, 1 Gallon

Apply when temperature is above 50F/10C. and surface is dry, free of dirt, loose flaky paint and coatings, oil, grease, coal tar or other contaminants. Typically cures within 24-48 hrs. Do not freeze. Store in a warm area. Do not apply in wet conditions or if rain is forcasted within 24 hrs. Not meant as a constant walking surface.

Coverage - Vertical Surfaces - Apply a minimum final thickness of 1 gallon per 25 sq ft (2.3 sq m). It should require around 2-3 heavy coats to achieve a 30 mil (0.76 mm) (DFT) membrane.
Flat/Ponding Surface - Apply a minimum final thickness of 1 gallon per 15 sq ft (1.4 sq m). It should require around 4-5 heavy coats to achieve a 60-80 mil (1.5-2 mm) (DFT) membrane.

Apply next coat when dry to touch and nothing is wet underneath; tacky is okay.

Generally 6-8 hrs 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.
