Soudal Primer 100 - Polyurethane Sealant Surface Primer

When embarking on a construction or renovation project, ensuring the longevity and effectiveness of sealants or adhesives on porous surfaces is paramount. Soudal Primer 100 is specifically designed for this purpose, providing a high-quality foundation that enhances adhesion and durability.

Below are detailed instructions on how to utilise Soudal Primer 100 effectively, encompassing substrate suitability, surface preparation, application method, coverage, and cleaning.

Substrate Suitability:

Soudal Primer 100 is universally compatible with all porous building substrates. This encompasses a wide range of materials commonly encountered in construction and renovation projects, including concrete, wood, stone, and various other porous surfaces.

Its formulation is tailored to penetrate these materials, creating an optimal surface for the application of polyurethane or hybrid polymer-based sealants and adhesives.

Surface Preparation:

To achieve the best results with Soudal Primer 100, it's crucial to begin with proper surface preparation.

The substrate should be clean, dry, and thoroughly free of dust, grease, and any other contaminants that could impede adhesion. This can often involve a thorough brushing or wiping down of the surface, and in some cases, the use of a cleaner such as White Spirit to remove grease or oil.

Ensuring the surface is dry is also essential, as moisture can affect the primer's performance. The meticulous preparation of the surface not only guarantees optimal primer adhesion but also significantly enhances the longevity and effectiveness of the subsequent sealant or adhesive application.

Application Method:

Soudal Primer 100 is designed for ease of application, making it accessible for both professional contractors and DIY enthusiasts. Using a brush or roller, apply Soudal Primer 100 in one full covering layer across the prepared surface. It's important to ensure that the primer is spread evenly, covering the entire area where the sealant or adhesive will be applied. This uniform application is key to achieving a consistent and reliable bond.

After the application of Soudal Primer 100, there is a specific window during which the sealant or adhesive should be applied for optimal results. The sealant should be applied no sooner than 1 hour and no later than 4 hours following the primer's application. This timeframe allows the primer to achieve the necessary level of tackiness and readiness to securely bond with the sealant or adhesive.

Coverage:

The coverage rate of Soudal Primer 100 is highly efficient, making it a cost-effective solution for large-scale projects.

While specific coverage may vary based on the porosity of the substrate and the method of application, users can generally expect to cover approximately 5m² per litre of primer.

This efficient coverage ensures that a single 500ml flask can prepare a significant surface area, providing an economical option for projects of various sizes.

Cleaning:

In the event of spills or if the need arises to clean tools, uncured Soudal Primer 100 can be effectively cleaned with White Spirit.

It's important to perform this cleaning immediately after use, as once the primer cures, it becomes more challenging to remove.

By promptly addressing any spills or cleaning tools with White Spirit, users can maintain a clean work environment and ensure their tools are ready for future use.
