KERACRETE ADF100

Acrylic Cementitious Highly Flexible Waterproofing Membrane

KERACRETE ADF100 is a two-component product. It consists of a liquid component, which is a blend of highly durable and flexible polymers, and a powder component made of special cements, finely graded fillers, and active chemicals.

📍 Key Uses

This membrane is designed for waterproofing in a wide range of applications:

Bathrooms and Wet areas
Water Storage Tanks
Swimming pools
Flat Roofs
Basement Walls
Planter Boxes
Tunnels
Retaining Walls and Foundations
Balconies, terraces, and roof floors

✨ Advantages

Water Pressure Resistant: It's resistant to water pressure up to 7 bar, making it suitable for both water-retaining (like tanks) and water-excluding (like basements) structures.
Excellent Crack Bridging: The membrane can bridge cracks up to 2mm, allowing it to move dynamically with the structure while maintaining its waterproofing performance.
High Bond Strength: Its polymer composition provides a very high bond.

📏 Coverage

Coverage is approximate and will depend on the surface's profile and porosity. Here's a general guide:

For 1mm thickness: 1.5kg/m²
For 2mm thickness: 3.0kg/m²

Applying the Product

A quick overview of the application process. (Note: Always refer to the full Technical Data Sheet before starting.)

1. Preparation

Substrates must be clean and free of contamination like oils, grease, and dust.
Surfaces must be sound. Any weak or friable surfaces may need repair.
Cracks larger than 1mm should be cut into a V-shape, cleaned, and filled using mixed KERACRETE ADF100. A 50mm reinforcing scrim should be applied over the crack.

2. Priming

For very porous substrates: Seal the substrate using a mix of 3 parts clean water to 1 part KERACRETE liquid. Allow it to dry for at least 40 minutes.
For external or normal mineral substrates: Pre-wet the surface with water until it has a damp appearance. Do not allow water to pond. Apply the membrane immediately after.

3. Mixing

The product is supplied in ready-mixed quantities.
In a clean container, add all the liquid component.
Slowly add the powder component while mixing.
Mechanical mixing with a slow-speed mixer (200-600 rpm) is recommended.
Mix until you achieve a lump-free, smooth, and homogenous slurry.
Important: On no account should additional water be added, as this will affect performance.

4. Application

Pour the mixed liquid membrane onto the prepared substrate.
Spread it using a comb, serrated trowel, or squeegee.
A minimum of 2 coats should be applied, perpendicular to each other.
Allow the membrane to cure for at least 24 hours before applying another coat or allowing light foot traffic. Full cure is achieved after 28 days.

📦 Storage & Packaging

Packaging: KERACRETE ADF100 is supplied in a 23 kg/set.
Storage: The product has a 6-month shelf life from its manufacture date. It must be stored correctly in its original packaging, out of sunshine, and at temperatures between 20°C - 40°C.
