Plaster Hardener

✅   Plaster Strengthening and Reinforcement : This plaster hardener is specifically designed to improve the strength and durability of plaster surfaces. It penetrates deep into the material’s structure, reducing its porosity and significantly increasing its hardness. Ideal for sculptures, moldings, coatings, and all plaster surfaces requiring long-lasting reinforcement.

✅   Money-back Guarantee : We have complete confidence in the effectiveness of our plaster hardener. That’s why we offer a money-back guarantee. If the product does not fully meet your expectations after application according to the recommendations, you can request a refund with no conditions, ensuring a risk-free purchase.

✅   Compatible with Various Mineral Surfaces : This hardener is not limited to plaster; it is also effective on lime-based coatings, stucco, porous concrete, and certain mortar surfaces. It is suitable for both renovation work and artistic or architectural creations, providing a versatile solution to reinforce and stabilize different mineral supports.

✅   Optimized Economic Coverage : Thanks to its concentrated formula, 1 liter of product can treat between 3 and 5 m², depending on the porosity and thickness of the surface. It can be applied in one or multiple layers to adjust the hardening effect as needed, ensuring cost-effective and efficient use.

✅   Safe and Non-Toxic Product : This hardener is formulated without harmful solvents and does not emit toxic fumes. It is safe for users and the environment, allowing application without the need for special protective equipment. It can be used indoors or outdoors without risk to air quality or adjacent surfaces.

✅   Easy Application and Quick Implementation : This product is ready to use and requires no prior mixing. It can be applied simply with a brush, roller, or sprayer, quickly penetrating the plaster to reinforce its structure without altering its appearance. Its smooth and even application makes it suitable for both professionals and DIY users.

✅   Enhanced Plaster Durability and Resistance : Once applied and dried, this hardener provides long-lasting protection against wear, cracks, and mechanical impacts. It significantly improves plaster’s resistance to handling and external aggressions, ensuring that treated surfaces maintain their integrity for years without requiring frequent maintenance.

✅   Fast Drying for Significant Time Savings : This hardener is designed to penetrate quickly into the plaster and dry within a few hours, depending on the surface’s absorption rate. It helps accelerate finishing times by making the plaster more durable without slowing down project progress. Its rapid efficiency is ideal for construction sites where time is a key factor.

Usage Protocol

🔹 Surface Preparation : Before application, ensure that the plaster surface is clean, dry, and dust-free. If there are paint residues or dirt, clean the area to allow better penetration of the product.

🔹 Recommended Dosage : Apply between 0.2L and 0.5L per m², depending on the porosity of the plaster and the level of hardening required. A single coat may be sufficient for light reinforcement, while a second application will further strengthen the structure.

🔹 Hardener Application : Apply the product using a brush, roller, or sprayer, ensuring even coverage of the entire surface. Work in sections to avoid premature drying before the product has penetrated properly.

🔹 Absorption Time : Allow the product to penetrate the plaster for 10 to 30 minutes. If applied to a very porous surface, a second coat may be applied after the first one is absorbed.

🔹 Complete Drying : Let it air dry for 12 to 24 hours before applying a finish (paint, coating, or varnish). Avoid excessive contact or sanding before the product has completely hardened the material.

🔹 Maintenance and Finishes : Once the plaster has hardened, it can be sanded, painted, or covered with a coating as needed. This hardener also improves the adhesion of paints and varnishes, ensuring an optimal and durable finish.

🔹 Tool Cleaning : After application, clean tools immediately with clear water to prevent the product from hardening and to extend the lifespan of the equipment used.
