Soudabond TIMBER - Joint & Joist PU Wood Adhesive Foam

When using Soudabond TIMBER High-Yield PU Adhesive, it is crucial to follow detailed instructions to ensure optimal results. This guide provides comprehensive steps covering substrate suitability, surface preparation, application method, and cleaning, ensuring the efficient and effective use of the product.

Substrate Suitability:

Soudabond TIMBER is compatible with a variety of substrates, including plywood, lumber (whether frozen, moist, or treated), OSB, particle board, concrete, metals, masonry, stone, AAC-bricks, and plaster.

However, it is important to note that this adhesive is not suitable for use on substrates with a water film, standing water, or materials like PE, PP, PTFE, and silicone.

To ensure the best results, all substrates should undergo a compatibility and adhesion test before application.

Surface Preparation:

Prior to application, ensure that the adhesive surfaces are stable, clean, and free of contaminants such as grease, oils, or separating agents. It's essential to cover adjacent areas to protect them from soiling, particularly in windy conditions.

For indoor use, maintain good ventilation as the product is flammable during dispensing.

Personal protective equipment, such as goggles and gloves, should be worn for safety.

Application Method:

Begin by securely attaching the can to the Foam Applicator Gun, ensuring a tight fit. Shake the gun with the valve pointing downwards for approximately 30 seconds, mixing the contents thoroughly for optimum adhesive quality and yield. For extended periods of non-use, re-shaking is necessary to maintain adhesive quality. Adjust the adhesive bead diameter using the gun's adjusting screw, bearing in mind that the emptier the can, the more the screw needs to be opened.

The adhesive should be applied in uniform beads of 1-2cm onto the mounting studs, maintaining a 1-2 cm distance between the gun nozzle and the substrate. Once applied, place the subfloor decking onto the gel adhesive within 20 minutes. Avoid removing and reapplying panels as it significantly reduces the adhesive strength.

In conditions of high temperature and low humidity, you can accelerate curing by lightly spraying the adhesive bead with water. After setting the panels, secure them with mechanical fasteners while maintaining pressure.

Optimal Temperatures for Use:

The can temperature should ideally be between +5°C and +25°C, with an optimal range of +15°C to +25°C. If necessary, slowly bring the can to the optimal temperature using cool or lukewarm water. The surface temperature range for application is between -15°C and +35°C.

Cleaning:

For cleaning, use Soudafoam Gun & Foam Cleaner or Swipex Cleaning Wipes before the adhesive cures. After curing, the adhesive can only be removed mechanically or with the use of Soudal Cured PU Foam Remover.
