Primer Hardener

✅   Improved resistance and primer adhesion : This primer hardener is specifically designed to reinforce the structure of primer layers before applying paint or a final coating. It optimizes surface adhesion while improving resistance against mechanical and chemical damage, ensuring a more durable and professionally finished result.

✅   Money-back guarantee : We have complete confidence in our primer hardener’s effectiveness. That’s why we offer a money-back guarantee. If the product doesn’t meet your expectations after following our application recommendations, you can request a no-questions-asked refund, thus ensuring a safe and risk-free purchase.

✅   Compatible with a wide range of materials : This hardener is suitable for primers used on metal, wood, plastic, concrete, cement, and stone. It works with acrylic, epoxy, polyurethane, and glycerophthalic primers, offering maximum versatility for all types of projects, whether automotive, construction, or decorative items.

✅   Optimized economic yield : Due to its concentrated formula, 1 quart of hardener can treat up to 5 quarts of primer, thus reducing the necessary quantity of product and enhancing its performance. Its ability to reinforce adhesion and primer resistance also limits the need for retouching, significantly lowering labor and material costs.

✅   A safe and non-toxic product : Formulated without harsh solvents or toxic emissions, this hardener poses no danger to the user or the environment. It can be handled safely without the need for specific protective equipment, ensuring a risk-free application both indoors and outdoors.

✅   Ease of application and optimal compatibility : This hardener integrates easily into primers without altering their texture, color, or application method. It blends directly before use, guaranteeing perfect uniformity and a professional finish without requiring additional technical adjustments.

✅   Enhanced durability and resistance : Once mixed with the primer, this hardener reinforces surface protection by improving resistance to impacts, moisture, and chemical products. It prevents premature flaking and provides long-lasting protection against wear, thus extending the life of your final coating.

✅   Rapid drying for considerable time savings : This hardener accelerates the drying process of primers while ensuring a progressive increase in resistance. It also reduces waiting time between coats, allowing a faster final finish and thereby optimizing production and application times.

Usage protocol

🔹 Primer Preparation : Ensure the primer is thoroughly homogenized before adding the hardener. If the primer is solvent-based or water-based, mix thoroughly to prevent any component separation.

🔹 Recommended Dosage : Add between 5% and 20% hardener depending on the type of primer and desired resistance. For surfaces subjected to extreme conditions (humidity, high temperature, shock exposure), a higher dosage is recommended.

🔹 Homogeneous Mixing : Gradually incorporate the hardener into the primer while continuously mixing with a manual or electric stirrer. Ensure a perfectly smooth and homogeneous blend.

🔹 Application of the Hardened Primer : Apply the primer as usual, using a spray gun, brush, or roller, following the manufacturer’s application instructions. The hardener does not alter the application method and ensures an even finish.

🔹 Drying Time : Allow the primer to dry according to the manufacturer’s recommended time. With the action of the hardener, drying is accelerated, allowing subsequent steps to be completed more quickly.

🔹 Complete Hardening : Avoid handling or recoating the surface prematurely. The primer reaches maximum resistance after 24 to 48 hours, thus providing a perfectly stable base for applying paint or the final coating.

🔹 Tool Cleaning : After application, immediately clean brushes, rollers, and spray equipment using the solvent recommended for the primer used (water for water-based primers, suitable thinner for solvent-based primers).
