Note: When Liquid Rubber Waterproof Sealant is immersed in water, it may appear slightly brown. Once fully dry, it turns to a deep black color.
Can it be painted over?
If you wish to paint over the sealant, apply one coat of our Primer / Sealer on top of the sealant first. This will ensure optimal adhesion and a smooth finish.
