Liquid Rubber Basement and Foundation( Stock tank) Repair Sealant - Waterproof Concrete Sealer & Crack Filler - Flexible Coating for Indoor & Outdoor Use - Waterproofing Paint - Black, 5 Gallon

For your concrete stock tank, the Liquid Rubber Foundation Sealant typically requires 3–4 coats minimum for concrete, depending on the surface condition and porosity.General application guidelines:
• Interior surfaces: 2–3 coats (50 sq ft/gallon per coat)

• Exterior surfaces: 3–4 coats (20 sq ft/gallon per coat)

• Between coats: Allow 4–6 hours drying time

• For porous concrete: Customers frequently report needing 4+ coats for concrete stock tanks and similar porous surfaces to achieve full effectiveness
Adding seam tape for reinforcement:The product documentation specifically recommends using Liquid Rubber Seam Tape (also called Geo-Textile) at critical joints, transitions, cracks, and seams—especially important for your stock tank. Here's how to incorporate it:
• Apply tape at: Tank seams, corners, where the tank meets the ground, and any existing cracks

• Installation: Apply one coat of sealant, embed the seam tape into it, then apply additional coats over the tape for reinforcement

• Coverage: Seam tape creates a stronger barrier against active leaks and movement stress

• Best practice: Customers recommend using the 3-course method with seam tape at critical stress points for maximum durability
What customers report for concrete tanks:Reviews suggest that porous concrete like stock tanks often requires more coats than the minimum recommendation. Some users mention applying 4–5 coats and still needing to monitor results. Key tip: Apply heavy, consistent coats and ensure each coat is fully tacky before the next application (not fully dry). Work in sections and lap overlaps by at least 6 inches for better adhesion. The seam tape will significantly improve long-term performance, especially on a working water storage tank.
