Waterproofing is more than just a protective finish—it’s a crucial layer that defends your structure from water damage, leaks, and deterioration over time. At Radiant Construction Chemicals, we’ve developed ConFlex 511, a high-performance, two-component waterproofing system designed to deliver long-lasting protection across a wide range of applications, including residential, commercial, and industrial projects.

This guide will walk you through the proper method of applying ConFlex 511 to ensure you achieve optimal results and long-term waterproofing performance.

What is ConFlex 511?

ConFlex 511 is a two-part, cementitious waterproofing system formulated for flexibility, strength, and durability. It consists of:

Part A: A high-quality cement-based powder enriched with chemical additives for enhanced performance.

Part B: A liquid polymer which enhance flexibility, bonding strength, and water resistance.

When mixed, the components form a smooth, brush able slurry that creates a seamless, watertight membrane over concrete and masonry surfaces.

Ideal Areas of Application

ConFlex 511 is an effective waterproofing solutions for various structures:

Roofs and terraces

Bathrooms and wet areas

Water tanks (internal and external surfaces)

Basements and retaining walls

Podiums, balconies, and lift pits

Swimming pools and other submerged surfaces

Step-by-Step Application Instructions

Step 1: Surface Preparation

Proper surface preparation is essential for effective waterproofing.

surface cleaning: Enusure all dust, grease, dirt, old coatings, or any loose particles are removed before application.

Check substrate: Ensure the surface is structurally sound and slightly damp—avoid overly wet or waterlogged conditions.

Repair defects: Use Radiant ConRep FR Mortar to fill cracks, voids, and damaged areas before applying ConFlex 511.

Step 2: Mixing the Components

to start with pour the Part B into a clean container.

Add Part A gradually: While stirring continuously, slowly add the powder into the liquid.

Mix until smooth: Use a mechanical stirrer or paddle to mix the material until a uniform, lump-free slurry is formed. Avoid air entrapment.

Step 3: First Coat Application

Apply with brush or roller: Use a soft brush or roller to spread the first coat in one direction (either vertical or horizontal).

Ensure even coverage: Avoid pinholes or uneven patches. The first layer should be consistent.

Allow curing: Let the first coat dry for 4–6 hours, depending on ambient temperature and humidity.

Step 4: Second Coat Application

The second cote application is recommended for effective and long lasting results it direction timeline will be assessed after seeking on ground conditions of the first coat. for further assistance please contact our support team to achieve desired outcome.

Maintain thickness: Ensure the total thickness meets the product’s recommended application standard. not too thin nor too thick.
