Acoustic Underlay Adhesive | AM Dispertec AR-7329

Acoustic Underlay Adhesive | AM Dispertec AR-7329

Choosing the right bonding agent is critical to the longevity of any flooring project. AM Dispertec AR-7329 is a premium, unilateral water dispersion specifically formulated for the installation of acoustic underlays, PVC, linoleum, and various textile floorings. Whether you are working with rolls or tiles, on horizontal floors or vertical walls, this Acoustic Underlay Adhesive provides a powerful, elastic bond that withstands intense foot traffic and structural vibration. By ensuring a permanent connection between the substrate and the finish, it eliminates the risk of floor failure in challenging environments.

Superior Bonding for Soundproofing Systems

In soundproofing, the connection between the subfloor and the acoustic layer must be airtight and permanent. This Acoustic Underlay Adhesive is the primary choice for Concrete Floor Soundproofing when bonding Eco-Lay or other resilient underlays. Its fast-setting formula creates a constant elastic film that doesn’t just hold the material in place but works in harmony with the acoustic system to prevent movement and “hollow” sounds. Because the formula is water-based and non-toxic, it is safe for use in residential homes, schools, and hospitals where air quality is a top priority.

Key Performance Properties

• Powerful Initial Grab: Formulated for a fast and strong setting, it allows for efficient installation workflows even on large-scale commercial sites.

• Elastic Durability: Once cured, the bond remains flexible to absorb structural stress without cracking or debonding from the subfloor.

• Multi-Surface Versatility: Suitable for a wide range of floor and wall coverings including vinyl, carpet, and textiles, providing a uniform finish across different material backings.

• Safety First: This product is non-flammable and free from toxic solvents, making it ideal for confined spaces and large-scale indoor projects.

Yield and Coverage Rates

To ensure you order the correct amount for your project, please refer to the yield estimates based on your application method:

• Roller Application: Approx. 220–280 g/m² (Recommended for flat, even surfaces).

• Spatula No. 1: 300–350 g/m².

• Spatula No. 2: 350–400 g/m² (Recommended for uneven substrates or heavier backings).

Installation & Application Guide

For a perfect bond using our Acoustic Underlay Adhesive, surface preparation is vital. The substrate must be dry, free from dust, grease, and oils, and completely free of any rising damp.

1. Preparation: Clean the substrate thoroughly. Never use soaps or detergents as they can leave a residue that interferes with the final bond.

2. Application: Apply the AM Dispertec AR-7329 using a spatula or roller, ensuring the amount applied is sufficient for complete impregnation of the material backing.

3. Waiting Time: Before laying the flooring, allow the glue to “tack off.” This varies between 20–60 minutes for spatula application and 10–30 minutes for roller application.

4. Storage: Keep tubs away from direct sunlight and frost. Store between +10°C and +35°C to maintain the chemical integrity of the dispersion.
