Spray. Apply. Sealed!
A well-sealed building envelope is the key to energy efficiency. Regrettably, the job of priming surfaces so that they can be properly sealed with insulating materials is often difficult and time consuming. With its new Ampacoll® Airmax spray primer, the Swiss supplier Ampack now promises to make the work a whole lot easier.
Professional and conscientious priming is hard work. Applying a sealant with open cans, trays, rollers and brushes takes a lot of time and working on overhead surfaces with liquid sealants tends to be strenuous. Nonetheless, it’s simply not an option to skip the priming. This is because porous and absorptive building surfaces, low temperatures and moisture can prevent you from achieving a tight seal. This is where the new spray primer Ampacoll® Airmax by Ampack plays such a helpful role because it allows you to complete the priming work quickly, easily and safely.
Ampacoll® Airmax serves as an adhesive base for Ampacoll adhesive strips on porous or rough surfaces such as masonry, plaster, concrete, rough-cut wood, and wood-fibre panels. Simply spray the solvent-containing, synthetic rubber Airmax in the corresponding width to the clean, dry and grease-free surfaces you need to seal in order to form a basis, and then apply the adhesive strips or panels. The spray primer makes it easier to complete overhead and vertical work. The new spray primer is also especially effective when you’re forced to work in difficult conditions involving moisture and low temperatures ranging down to -5°C.
Make sure to cover any sensitive surface elements before applying the spray. Thanks to the double-rotating spray nozzle, you can also precisely aim and adjust the spray to one of three different levels of volume. After application, the saturated surface begins to harden, with the ventilation time ranging from 10 to 40 minutes depending on the temperature and the surface properties. Once it dries, Ampacoll® Airmax remains sticky and provides a perfect substrate for all Ampacoll adhesive panels and strips.
Spray primer for Ampacoll adhesive strips on porous surfaces, such as masonry, plaster, concrete, bare wood, soft wood fibre board, etc. Suitable for use in difficult conditions (cold, damp).
- Sprayable, faster than with a brush
- Short drying time
- Permanently tacky
- Makes overhead and vertical work easier
