TUFINEIN Waterproof Sealant 70oz Clear – Transparent Water-Based Coating for Roofs, Walls & Outdoor Surfaces

Meet the TUFINEIN Waterproof Sealant, a 70 oz clear, water-based coating designed for indoor and outdoor projects. When applied, the product starts as a semi-transparent layer and cures into a clear waterproof membrane that helps resist moisture without changing the surface color or texture.

Key benefits and what it can do

• Clear, water-based formula suitable for roofs, walls, basements, sheds, gardens, gutters, skylights, pipes, bathrooms, chimneys, and window sills.
• Compatible with various materials including wood, concrete, brick, metal, and ceramic surfaces.
• Forms a dense waterproof coating that acts as a barrier against air, water, and moisture intrusion.
• Resistant to both high and low temperatures for a durable seal that protects underlying items and preserves aesthetics.
• Two to three coats can cover approximately 14 square feet per kilogram of product (about 1.3 square meters per kilogram).

How to apply and optimize results

• Apply with a brush, roller, or pour the coating for different project sizes.
• Cross-apply coats and allow 24 hours between coats for a long lasting membrane.
• Each coating should be applied at a width greater than 15 cm to create a continuous seal.
• Use in dry, sunny weather with an ambient temperature of 5 C or higher (41 F+).

Important considerations and limitations

Not suitable for long-term water immersion areas such as swimming pools, ponds, or bathrooms where the coating remains submerged. For projects with frequent water contact, plan accordingly and test on a small area first.

In everyday use, this coating can support seasonal protection of exterior wood, seal brick or concrete walls, or refresh damp basements. The clear finish helps maintain material appearance while adding a protective layer. As with any sealant, proper surface prep and ventilation influence the final outcome, so reviewing instructions before starting is advised.
