Preparation:
Before installing KPRO Floor LevelEase Duo 225, ensure that concrete, sand-cement, and calcium sulphate screeds are at least 28 days old and fully dry. The moisture content should be below 4% CM (around 6% Tramex or gravimetric). For screeds with underfloor heating, the limit is 3% CM (around 4.5% Tramex or gravimetric). Any joints in the substrate must be mirrored through the KPRO Floor LevelEase Duo 225 layer. Additionally, suitable perimeter strips should be used at edges and junctions to contain the fluid material and prevent movement during curing. For heated screeds, it is crucial to commission the heating system prior to installation. After commissioning, turn off the heating system and allow it to cool for at least 2 days before applying KPRO Floor LevelEase Duo 225.
Priming:
All surfaces must be thoroughly primed to ensure optimal performance of the levelling compound. Priming is essential to maximize the working time, maintain the flow life, and enhance adhesion, while also preventing air bubbles from rising through the compound. It is crucial to adhere to the manufacturer's specified drying time for the primer to achieve the best results.
Mixing:
To prepare KPRO Floor LevelEase Duo 225, mix one 20kg bag of the dry material with Component B, which is a 4.6kg bottle of dispersed acrylic. It is important not to add any additional water to the mix, as this may compromise the product's strength and overall performance. Begin by pouring the entire contents of the dispersed acrylic bottle into a clean mixing bucket. Gradually add the dry powder to the liquid while continuously mixing with a mechanical paddle mixer. Mix thoroughly until the mixture reaches a smooth, lump free, and homogenous consistency. Once mixing is complete, allow the material to rest for approximately one minute to realise any trapped air bubble. For applications involving large areas, it is essential to plan for sufficient workforce to ensure the material is poured and spread within the appropriate working time. If a layer thickness exceeding 25mm is required, KPRO Floor LevelEase 250 should be used instead, as it is specifically designed to accommodate thicker applications. Following these steps will help ensure optimal product performance and a professional finish.
Placing:
Pour the mixed KPRO Floor LevelEase Duo 225 onto the prepared substrate and let it flow and self-level within the first 15 minutes of its 20–30-minute working time. Use a steel trowel or squeegee to spread the compound evenly to the desired thickness. Since the maximum aggregate size is 0.5 mm, it is suitable for feather applications, with a minimum thickness of 2 mm. To achieve a smooth finish, use a spiked roller to release trapped air bubbles. During the working time, a steel finishing float can be used for precise feathering and refining edges.
Curing:
Protect the freshly applied surface from drafts until it hardens. Impermeable floor coverings can be installed after 12 hours*, depending on the material's thickness, room humidity, and temperature. Refer to the drying times listed in the previous page table for guidance.
