Mapei Primer G

Key benefits include strong adhesion to natural stones, elasticity to accommodate substrate movement, self-leveling ease of application, a quick setting capability for faster projects, and a formula that is lightweight and non-toxic for interior use.

Primer G is formulated for natural stones and is intended for interior applications. It can be used where a fast-setting, high-adhesion adhesive is required, and it may be suitable for certain exterior applications depending on substrate preparation and environmental conditions.

1) Prepare a clean, dry substrate free of dust and contaminants. 2) Open the container and use as-is (no mixing required). 3) Apply the adhesive paste evenly to the substrate with an appropriate trowel or for direct placement of natural stones, ensuring full contact with the back of the stone. 4) Install the natural stone pieces with gentle pressure and adjust as needed. 5) Allow the adhesive to cure according to ambient conditions before subjecting the installation to load.

Primer G has a short drying time designed to speed up installations. Drying and curing times depend on temperature, humidity, and substrate characteristics; interior projects typically progress quickly, but always follow project-specific conditions and allow proper curing before loading the fixed stones.

Yes. Primer G is described as lightweight and non-toxic, suitable for interior use where stone fixation is required. Always use appropriate personal protective equipment (gloves and eye protection) and ensure good ventilation during application.

Typical applications include fixing natural stones in interior spaces such as living areas, bathrooms, feature walls, and countertops. It can also be considered for specific exterior projects where substrate conditions and environmental exposure are appropriate.

Compared to other adhesive options on Fepy, Primer G offers quick-setting, high-adhesion performance specifically for natural stones with self-leveling properties. For reference, these alternatives on Fepy include: Ultrabond ECO 830 (https://fepy.com/product/mapei-ultrabond-eco-830) and Adesilex P9 (https://fepy.com/product/mapei-adesilex-p9). These products provide different coverage, cure profiles, and substrate compatibility, so choose based on stone type, project size, and environmental conditions.

Consider stone type and thickness, interior vs. exterior exposure, required cure time, substrate roughness, and potential substrate movement. If you need even faster cure, greater flexibility, or different substrate compatibility, compare products like Ultrabond ECO 830 or Adesilex P9 to determine the best fit for your project.

Store Primer G in a cool, dry place in a tightly closed container. Keep away from extreme temperatures and moisture. Before use, inspect the container for any signs of separation or contamination. Keep tools and surfaces clean to ensure optimal adhesion.

Wear appropriate PPE such as gloves and eye protection. Ensure good ventilation in the work area, avoid skin contact, and wash thoroughly after handling. Follow any additional safety data on the product label and MSDS for best practices.

Coverage depends on substrate texture, stone dimensions, and the desired thickness of the adhesive layer. For accurate quantities, consult the product data sheet or contact Fepy support with your project details (stone size, surface area, and substrate type) to get a precise estimate.
