The PRIMO 2x20 sheet (40m2) is an innovative waterproofing membrane specifically designed for use on floors and walls, offering a reliable and versatile solution both indoors and outdoors. Made from synthetic fiber nonwovens on both sides, the PRIMO provides excellent strength and durability to protect surfaces in a variety of environments, such as showers, decks, balconies, flat roofs, cornices, and window frames. However, unlike WATER STOP (W-S) film, it is not suitable for pool waterproofing, making it more suitable for residential and commercial applications outside of this specific category.

The technical design of the PRIMO includes a double interlayer structure entirely made of 100% polypropylene. This composition differentiates it from the W-S sheet, whose intermediate layers are a mixture of polyester (50%) and polypropylene (50%). Thanks to this approach, the PRIMO ensures reliable protection against water leakage, maintaining its integrity even under demanding conditions. In addition, the weight of PRIMO film is 190 g/m², which makes it lighter than W-S (250 g/m²), ideal for projects that require an efficient solution without adding additional weight.

One of the main features of the PRIMO is its compatibility with C2 type adhesive cements, which ensures excellent grip during the installation process. This compatibility makes it easy to use in various construction and renovation projects, allowing professionals to achieve effective waterproofing with fewer complications.

While PRIMO shares many similarities with W-S foil, it also has key differences that should be considered when selecting the right product. For example, PRIMO sheet is less malleable than W-S due to its composition and weight. However, it remains highly functional and reliable for most standard applications. This makes it an excellent choice for projects where high malleability is not required, but reliable waterproofing performance is required.

The PRIMO film stands out for its durability and ease of installation. Its design ensures long-term protection against moisture issues, resulting in safer and more stable surfaces in any environment. It is particularly effective in areas such as showers, terraces and balconies, where exposure to water and humidity can be constant. In exterior applications, such as flat roofs or cornices, its ability to withstand the elements ensures that surfaces remain protected for years.

In conclusion, PRIMO sheet is an advanced technical solution for the waterproofing of floors and walls in a wide range of applications. Its polypropylene double interlayer design, together with its optimized weight and compatibility with C2 adhesive cements, make it an ideal choice for projects looking for a balance between reliability, lightness and functionality. However, it is important to consider the specifications of the project, as it is not suitable for waterproofing swimming pools, where the WATER STOP sheet could be a more suitable alternative.
