ARDEX AM 100 is a rapid-setting, grey sand and cement render designed to facilitate quick project turnaround. This preblended product requires only the addition of water to achieve a slump-free mortar that can be applied in a thickness range of 2-30mm in a single coat. The primary advantage of ARDEX AM 100 lies in its ability to accommodate both very thin and substantial layers, making it an ideal choice for applications where conventional sand and cement renders would be impractical due to drying time constraints or required thickness. Its versatility extends to a range of surfaces, including in-situ concrete walls, brickwork, and block work. Additionally, ARDEX AM 100 is suitable for both internal and external environments, even in high-moisture areas such as swimming pools.

 

Key Points:

  1. Rapid Setting: ARDEX AM 100 is designed for quick application and can be tiled over in as little as 2 hours, making it ideal for fast-paced projects.
  2. Flexible Thickness Range: This render can be applied in a thickness range from 2mm to 30mm in a single coat, accommodating various project requirements and conditions.
  3. Versatile Applications: Suitable for rendering a variety of surfaces including in-situ concrete, brickwork, and block work, ARDEX AM 100 is effective in both internal and external settings.
  4. Moisture Resistant: The product is appropriate for use in high-moisture environments such as swimming pools, ensuring durability and performance in challenging conditions.

 

Coverage: ARDEX AM 100 has an approximate coverage rate of 1.3 kg per square meter per millimeter of thickness. For example, a 25 kg bag of ARDEX AM 100 will cover around 3.2 square meters when applied at a thickness of 6 mm.

Storage and Shelf Life: To ensure optimal performance, ARDEX AM 100 should be stored in its unopened packaging, elevated from the ground, in a cool, dry environment, and shielded from excessive draughts. When stored under these conditions, the product has a shelf life of 12 months from the date indicated on the packaging.

ARDEX AM 100 is a versatile, rapid-setting render capable of being applied in a single coat from 2mm up to 30mm in thickness. This product excels in scenarios where conventional sand and cement renders cannot meet the required drying times or thicknesses. It is suitable for rendering properly prepared in-situ concrete walls, brickwork, and blockwork. ARDEX AM 100 is ideal for both internal and external applications, including in demanding environments like swimming pools.

 

Surface Preparation

Ensure that all surfaces are stable and that any movement joints are carried through to the tiling surface. The areas to be rendered must be clean, firm, and free from dust, dirt, oil, grease, paint, gypsum plaster, and other contaminants that could impair adhesion. Mechanical preparation equipment may be necessary to achieve this. Allow sufficient drying time as specified in BS 5385: in-situ concrete walls, brickwork, and blockwork should be allowed to cure and shrink for at least 6 weeks. For concrete substrates, expose the aggregate surface as recommended in BS 5385. Settlement cracks should be filled with rendering mortar, though cracks caused by structural movement may not be fully resolvable. Small cracks should be cut out and widened to improve adhesion. Metal components must be protected against corrosion, and anchored reinforcements should be installed and mechanically fixed to backgrounds such as dense surfaces (e.g., glazed bricks or ceramic tiles), timber frames, old paint finishes that cannot be removed, weak surfaces, and areas above the first floor externally. All reinforcement and mesh must be secured according to the manufacturer’s instructions and/or BS 5385. Note: Proper substrate preparation is essential for ensuring the adhesion of the render mortar.

Mixing

The recommended mix ratio is approximately 3.5 parts ARDEX AM 100 powder to 1 part clean water by volume. A 25kg bag of ARDEX AM 100 requires about 5 liters of water. For slightly improved workability, an additional 0.5 liters of water per 25kg bag can be added, making a total of up to 5.5 liters per bag. Mix the ARDEX AM 100 powder with water in a clean container, stirring thoroughly until a slump-free mortar is achieved. Using an ARDEX mixing paddle with a 10mm chuck and a variable-speed electric drill makes mixing easier, or a forced action mixer can be used for larger batches. The pot life of the mixed mortar is approximately 30 minutes at 20°C, with variations depending on temperature.

Application

Apply ARDEX AM 100 at temperatures above 5°C. Start with a 1-2mm thick skim coat or bonding layer, then apply the remaining thickness (up to 30mm) while still fresh. For greater thicknesses, the material can be applied in two layers. For instance, for a total thickness of 30mm, apply a 25mm layer, allow it to set, and then apply a 5mm top layer. Always ensure that the top layer is thinner than the initial layer.

Treatments & Tiling

Depending on the porosity of the background, additional treatments such as wood floating can be performed between 40 minutes to 1 hour after application at 20°C. If needed, ARDEX waterproof coatings, such as ARDEX WPC and ARDEX S 7 PLUS, can be applied typically after 2 hours at 20°C, following the relevant product data sheets. Tiles can generally be installed as soon as 2 hours after application using an appropriate ARDEX Cement-Based Tile Adhesive. Note that these times may vary based on site conditions, with extended times at lower temperatures and shortened times at higher temperatures.
