Waterproofing for Swimming Pools: Best Products & Application Methods

29, May 2025

If you own a swimming pool, you know how crucial it is to keep it leak-free and structurally sound. Waterproofing for swimming pool areas isn’t just about preventing water from escaping—it’s about protecting the structure from damage caused by constant exposure to moisture. Whether you’re dealing with waterproof walls outside or the interior surfaces of the pool, choosing the right waterproof solution can save you from costly repairs down the line.

In this blog, we’ll explore the best products and application methods for water proofing your swimming pool, with insights from high-performance solutions like Seep Guard Seep Blocker Pro 2K.

Why Waterproofing Your Swimming Pool is Essential

Swimming pools are constantly exposed to water, chemicals, and temperature fluctuations. Without proper waterproofing for swimming pool structures, you risk:

• Leaks and seepage, which can weaken the foundation.

• Cracks due to thermal expansion and contraction.

• Efflorescence (white salt deposits) and mold growth.

• Structural damage from prolonged water exposure.

A high-quality waterproof solution acts as a shield, ensuring your pool stays durable and leak-free for years.

 

Best Products for Swimming Pool Waterproofing

When it comes to water proofing pools, not all products are created equal. You need a coating that offers:

• Strong adhesion to concrete and masonry.

• Elastomeric properties to handle movement and cracks.

• Resistance to hydrostatic pressure (both positive and negative).

• Anti-fungal and anti-efflorescence properties.

One such product is Seep Guard Seep Blocker Pro 2K , a polymer-modified, cementitious coating designed for high-moisture areas. Here’s why it’s a great choice:

Key Features of a Premium Waterproofing Coating

1. Waterproofing: Waterproofing protection of up to 5 bars of positive and negative hydrostatic pressure

2. Durability: Safeguards the building surface against the damage caused by leakage and seepage.

3. Elongation: It has highly elastomeric properties to withstand stress resulting from thermal expansion & contraction. It offers remarkable elongation up to 90% at break.

4. Crack Bridging: Excellent crack bridging properties due to presence of German Elastomeric polymers

5. Food grade certified: The product is certified from Central Food Technological Research Institute and is safe to be applied in swimming pools

6. High solid content: The acrylic polymer has high solid content which offers remarkable waterproofing properties. This product resists Efflorescence & provides long lasting effect

7. Anti-Efflorescence: This product resists Efflorescence & provides long lasting effect.

8. Anti-Carbonation: Guards the concrete structure from the effects of carbonation.

9. Eco-friendly: Zero Volatile Organic Compound (VOC)

10. Algae & Fungi Resistant: Prevents build-up of algae and fungi on the surface.

HOW TO APPLY

Surface Preparation

• Ensure that the plumbing system is leak-free with a pressure test. Rectify the leakages if present before commencement of waterproofing application.

• Remove all the loosely adhering material like dirt, dust, organic solvent (de-shuttering/curing free compound) & oil etc. from the surface by using emery paper, chisel, or wire brush etc.

• In case of efflorescence, remove the plaster up to the brick level and clean the masonry surface thoroughly.

• Surface cracks (less than 3mm) must be filled by crack filler products & bigger cracks (more than 3mm), honeycombing in concrete, damaged portion and hollow areas must be repaired by polymer modified mortar/ polymer modified fibre reinforcement repair mortal before application.

• Surface should be pre-wetted to make saturated surface dry (SSD) condition.

Mixing

• Mixing ratio – Powder: Liquid = 2:1

• Slowly add 2 kg of powder product with 1 Kg of liquid polymer to make slurry.

• Mixing should be carried out preferably by a mechanical stirrer (3-5 minutes).

• Leave the slurry for 5 minutes after thorough mixing to release trapped air, to get the best performance. Prepared slurry should be used within the pot life.

Product Application

• After thorough mixing apply the first coat of Seep Blocker Pro 2K on the clean & dry wall/substrate surface uniformly with the help of painting brush.

• Allow the surface to dry for at least 5-6 hours & then apply second coat of the product. Application of second coat must be applied in crosswise direction for better results.

• The total thickness of both the coats should be limited to maximum 1 to 1.2 mm.

• Waterproofing should be carried at least 300 mm on the vertical surfaces above the floor finish level. For the splash zone of shower in bathroom, the waterproofing should be carried out to 1.8 metre to 2.1 metre. In other wet areas the vertical surface should be waterproofed for a minimum height of 150 mm.

• The treatment should be left as is for 3-5 days to air cure before carrying out ponding test.

Ponding Test

•Conduct a 48-hour ponding test at a 50mm depth after closing all outlets and address any water seepage or leakage with remedial actions.
