Uneven subfloors can cause issues like creaking, cracking tiles, or uneven wear on your new flooring. Self-leveling compound, a polymer-modified cement mix, flows easily to fill dips and level surfaces. It’s ideal for preparing wooden subfloors, such as plywood, particleboard, or yellow tongue, for various floor coverings. Here’s why it’s a top choice: Quick and Efficient: Dries in hours, allowing faster flooring installation. Versatile: Works on timber, concrete, and tiled subfloors when properly prepped. Cost-Effective: Saves time and money compared to replacing subfloors. Durable: Provides a strong, smooth base for long-lasting flooring. Source Inspiration: This article draws on expert insights from flooring professionals, including tips from FloorVenue, ensuring practical and reliable advice. Preparing Your Wooden Subfloor for Self-Leveling Compound Proper preparation is critical to avoid cracking or adhesion issues. Wooden subfloors require extra care due to their flexibility and susceptibility to moisture. Follow these steps to get started: 1. Inspect and Repair the Subfloor Check for Stability: Ensure the subfloor is structurally sound, with no loose boards or excessive movement. Replace warped or damaged sections. Seal Gaps: Use painter’s caulk to fill joints between plywood sheets to prevent compound leakage. Remove Debris: Sweep or vacuum to eliminate dust, nails, or old adhesive. 2. Waterproof and Prime Apply Waterproofing: Wooden subfloors like timber or particleboard need a waterproof primer to prevent moisture absorption. Prime the Surface: Use a compatible primer to enhance adhesion. Let it dry completely to avoid bubbles or cracking. Skipping this step can lead to failure. 3. Address Specific Subfloor Types Plywood or Particleboard: Always seal and prime to handle the compound’s weight. Yellow Tongue Flooring: Requires waterproofing to prevent swelling. Magnesite Subfloors: Avoid self-leveling compounds due to potential asbestos risks; consult a professional. How to Apply Self-Leveling Compound on Wooden Subfloors Once your subfloor is prepped, applying the compound is straightforward but requires precision. Here’s a step-by-step guide: Choose the Right Product: Select a self-leveling compound designed for wooden subfloors, like ARDEX K900BF or Cemimax DL59, which offer flexibility for timber. Mix the Compound: Follow manufacturer instructions, typically mixing with water in a 25L bucket. Use a drill with a mixing paddle for a lump-free consistency. Pour and Spread: Start at the room’s far end, pouring the compound and spreading it with a trowel or gauge rake. Work quickly, as it sets in 20–30 minutes. Smooth the Surface: Use a spiked roller to remove air bubbles and ensure an even finish. Allow Drying Time: Thin layers (1–3mm) dry in 2–4 hours, while thicker layers (up to 50mm) may take 48 hours. Check product guidelines. Pro Tip: For thicker applications (over 20mm), consider adding metal lath to reinforce the compound and prevent cracking. Common Mistakes to Avoid To ensure a flawless finish, steer clear of these pitfalls: Skipping Primer: This leads to poor adhesion and cracking. Ignoring Subfloor Condition: Unstable or dirty subfloors compromise results. Overmixing with Water: Too much water weakens the compound, causing cracks. Applying Over Floating Floors: Remove existing floor coverings first. Rushing the Process: Allow adequate drying time before installing flooring. Benefits of Using Self-Leveling Compound Investing in self-leveling compound offers long-term advantages for Australian homeowners: Enhanced Floor Longevity: A level subfloor reduces stress on tiles or timber, preventing cracks. Improved Aesthetics: Eliminates visible dips or bumps under thin flooring like vinyl. Compliance with Standards: Meets Australian floor level tolerances (e.g., max 4mm deviation over 2m). Versatility: Suitable for wet areas like bathrooms when using products like Cemimax DL59. Key Takeaways Prepare Thoroughly: Inspect, seal, and prime wooden subfloors to ensure adhesion and durability. Choose the Right Product: Use compounds designed for timber, like ARDEX or Cemimax, for best results. Follow Application Steps: Mix, pour, and smooth carefully, respecting drying times. Avoid Common Errors: Don’t skip priming or apply over unsuitable surfaces. Consult Professionals for Complex Jobs: For magnesite or heavily uneven subfloors, seek expert help.
