Transforming a plywood substrate into a sleek, durable concrete surface is not only feasible but also a smart choice for remodeling projects. This blog post delves into the step-by-step process of installing self-leveling concrete over plywood, as demonstrated by Duraamen’s experts
Understanding the Benefits
Installing concrete over plywood offers a unique advantage, particularly in remodeling scenarios. It provides an opportunity to leverage the existing structure without the need for extensive tear-outs, thus saving time and reducing construction waste.
Key Preparation Steps
- Ensure Plywood Stability: The plywood must be stable without any deflection; if it flexes, it needs reinforcement before proceeding.
- Surface Preparation: All seams and screw heads on the plywood must be well-covered to create a smooth base for the concrete.
- Moisture Protection: If moisture is a concern, applying a flexible waterproofing membrane over the plywood can safeguard the installation.
Installation Process
- Preparing the Plywood: Start with a firm, non-deflective plywood base. The surface should be meticulously prepared to ensure it is smooth and free from imperfections.
- Applying a Waterproofing Membrane: For areas prone to moisture, a waterproofing membrane is crucial before the concrete application.
- Mixing and Applying the Concrete: Use Duraamen’s Param 35M or Param 5500, which are designed for thin applications (3/8″ to 1/2″ thick) and lay down ultra-flat. These materials are ideal for ensuring a level and smooth surface.
- Finishing Touches: For a unique finish, products like Skraffino can be used over the base layer to create a hand-applied, aged concrete appearance.
FAQs
- Can I install self-leveling concrete on any type of plywood?
- Yes, but the plywood needs to be stable and free of flexing. Preparation is critical to ensure the surface is smooth and secure.
- What thickness should the concrete overlay be?
- Typically, a 3/8” to 1/2″ thickness is sufficient. This ensures a solid overlay without the risk of cracking or instability.
- Is it necessary to use a waterproofing membrane?
- If there’s a risk of moisture exposure, yes. A waterproofing membrane prevents moisture penetration, protecting both the plywood and the concrete.
- Can I apply a decorative finish over the self-leveling concrete?
- Absolutely! Products like Skraffino can be applied over the self-leveling concrete to give it a customized, decorative appearance.
Utilizing self-leveling concrete over plywood allows you to enhance the functionality and aesthetic of your space efficiently. With careful preparation and precise application, you can achieve a long-lasting and beautiful concrete surface atop an existing plywood base.
