Soudal Sprayable Insulation Foam is compatible with a wide range of substrates, enhancing its appeal for diverse construction and renovation projects. It adheres effectively to concrete, masonry, stone, wood, drywall, and various metals that are corrosion-protected, among other materials.
Surfaces that are inherently non-adhesive include polyethylene (PE), polypropylene (PP), polytetrafluoroethylene (PTFE), and silicone.
Before application, it is imperative to ensure that the substrate is stable, clean, and devoid of any substances that could impair adhesion such as dust, talcum, grease, or oils.
The product is best applied to substrates that are dry to the touch but can accept a degree of building moisture - however, substrates should not be wet or have standing water.
Effective surface preparation is crucial for optimal foam performance. Begin by clearing the application area of all debris, dust, and potential contaminants.
Surfaces must be thoroughly cleaned to remove grease or oil. For substrates exposed to the elements or those with old paint, a more rigorous cleaning may be necessary.
Moistening the surface lightly with a water sprayer can enhance the foam's adherence, especially in dry conditions. Always protect adjacent areas to prevent accidental soiling and ensure that the workspace is well-ventilated, particularly for indoor applications.
Wearing protective goggles and gloves is recommended to safeguard against accidental exposure during application.
To start, vigorously shake the aerosol can for at least 20 seconds to ensure the foam mixture is well agitated.
Attach the application nozzle securely to the tip of the foam applicator gun and fit the can onto the gun adaptor.
Adjust the nozzle orientation depending on whether a vertical or horizontal application is needed. The foam output can be controlled via the adjustment screw on the gun.
Begin applying the foam from a distance of 30-40 cm from the surface; this distance helps regulate the thickness and spread of the insulation layer. It is essential not to exceed a single layer thickness of about 2.5 cm.
For thicker requirements, apply subsequent layers after a minimum waiting period of 30 minutes between applications, re-moistening each layer as needed.
Soudal Sprayable Insulation Foam is designed for efficiency and extensive reach with a single 700 ml can covering up to 1 square metre at a 2 cm layer thickness after curing. This high yield makes it an economical choice for both large-scale and smaller projects.
For larger areas, multiple cans will be required, and planning your project in sections will help in achieving uniform thickness and consistent results across different surfaces.
After application, the foam will begin to expand and cure. Expansion can be up to twice the initial volume sprayed, so it is crucial to consider this when determining the amount of foam applied.
Once the desired expansion and curing have occurred, any excess or misapplied foam should be trimmed or shaped before it fully hardens. If over-spray occurs, it should be cleaned promptly before the foam cures.
Note that cured foam is not UV-resistant; exposed areas should be painted or covered to prevent degradation from sunlight exposure.
Immediate cleaning of the spray nozzle and gun with Soudafoam Gun & Expanding Foam Cleaner is recommended to maintain equipment and prevent clogging.
Test the cleaner on a small, inconspicuous area of the surface beforehand to ensure it does not damage the material, especially sensitive plastics or painted surfaces.
Cured foam is resilient and can only be removed mechanically or with a specially formulated Soudal Cured PU Remover.
