STEICO Interior Render L – The Multifunctional Lime Plaster for Healthy Indoor Spaces
STEICO Interior Render L is a high-quality lime-based plaster designed for multiple interior applications. The product was developed specifically for use with the STEICOinternal insulation system. You can use it to bond wood fiber insulation boards, create a reinforcement layer together with STEICO Mesh, or apply it as a decorative topcoat. In this way, it offers a complete and versatile solution for ecological and healthy wall insulation.
This lime-based plaster is vapour-permeable, alkaline, and resistant to mould growth. It helps create a naturally balanced indoor climate by allowing walls to breathe. Thanks to its open-pore structure, moisture can move freely through the wall, keeping it dry and durable over time.
You can apply STEICO Interior Render L either by hand or with a machine. Its smooth consistency ensures pleasant and accurate handling. Craftsmen appreciate its excellent adhesion to STEICO wood fiber boards and its reliable performance across different layers. Because it works as an adhesive, reinforcement, and finish coat, you only need one product for the entire wall system.
As a topcoat, STEICO Interior Render L achieves a natural look with a layer thickness of 2–3 mm. You can felt, brush, or smooth the surface depending on the desired texture. The result is a breathable, natural wall finish that gives rooms a warm and harmonious character.
When combined with STEICOinternal and STEICO Mesh, this plaster forms part of a perfectly coordinated insulation system. STEICOinternal provides effective thermal insulation, while STEICO Mesh ensures surface stability and prevents cracks. Together, they create a durable and visually appealing finish that improves both comfort and energy efficiency.
The system works equally well for energy-efficient renovations and eco-friendly new buildings. Because all components are made from natural, pollutant-free materials, the result is a healthy and sustainable indoor environment. Homeowners and builders who care about ecology and comfort benefit from a long-lasting and environmentally responsible solution.
In summary, STEICO Interior Render L combines versatility, natural performance, and exceptional quality. It supports the complete interior insulation process – from bonding and reinforcement to the final decorative surface – ensuring healthy, durable, and beautiful walls for years to come.
