Parquet stratifié: la préparation pour un support plat (ragréage et OSB)

In this video, I show you how to prepare a floor with up to 2.3 cm of difference between its highest and lowest points before installing laminate flooring. The concrete slab was poured in several stages and has numerous uneven surfaces. To achieve a stable and durable base, I implement a solution combining a leveling compound, an adjustable support structure, and OSB panels. The process includes: ✅ Precise measurement and leveling using a laser ✅ Use of screws and wall plugs as height guides for leveling compound application ✅ Quick leveling compound application to correct the main imperfections in the slab ✅ Adjustment of remaining unevenness using shims under battens serving as support blocks ✅ Installation of OSB panels on the blocks with PU adhesive to ensure a solid and quiet base for the future laminate flooring This method allows for a perfectly flat surface, even when the original slab has significant irregularities, while minimizing the thickness and quantity of leveling compound required! ################### Equipment used in this video: ➡️ Lasgoo LG-3DS & 3Dx Laser: https://amzn.to/3Zr7NKs - https://amzn.to/3Qj0rJ0 ➡️ Bosch Laser Rangefinder: https://amzn.to/3RU8X1E ➡️ 1.5m Mason's Ruler: https://www.leroymerlin.fr/produits/r... ➡️ Stanley 5M Tape Measure: https://amzn.to/47DGLlP ➡️ Stanley Fatmax Utility Knife: https://amzn.to/3MY2Un6 ➡️ Stanley 30L Wet & Dry Vacuum Cleaner + Power Tool: https://amzn.to/46drzvk ➡️ Pica Automatic Pencil: https://amzn.to/3PQa0w6 ➡️ Pack of 10 Pica Leads: https://amzn.to/3RsS8sl ➡️ Sharpie Fine Point Markers: https://amzn.to/4dd0hJ5 ➡️ Spax Torx Screws 4x30 x180: https://amzn.to/4xoS5QO ➡️ Rubson FT101 PU Adhesive: https://amzn.to/49R1XZt ➡️ Wolfcraft Caulking Gun: https://amzn.to/46kuPFk Power Tools: ➡️ Bosch Pro 18V Multi-Tool: https://amzn.to/4v6LZTq ➡️ Saw Bosch Pro 18V Jigsaw: https://amzn.to/444ZJCi ➡️ Bosch Pro 18V 8.0Ah Battery: https://amzn.to/3WgobfI ➡️ Bosch Pro 18V 4.0Ah + 5.5Ah Battery Set with Charger: https://amzn.to/457n6t0 ➡️ Metabo Mitre Saw: https://amzn.to/49quNgb ➡️ DeWalt 18V 5Ah Battery: https://amzn.to/4ttqiw4 ➡️ DeWalt 18V Compact Drill Driver: https://amzn.to/3YoVlej ➡️ DeWalt Fast Battery Charger: https://amzn.to/4xtfWPq PPE: ➡️ Ear protection: https://amzn.to/4gfRY3G ➡️ DeWalt Safety Glasses: https://amzn.to/4vAJw3q ➡️ 10-Pack of 3M Disposable Dust Masks: https://amzn.to/3NKpVKU ➡️ 12-Pair Pack of HyFlex Gloves: https://amzn.to/3LDQn7f Amazon links are affiliate links 00:00 Intro 00:26 Slab Assessment and Strategy 02:28 1 - Leveling Compound Preparation - Measurements, Reference Screws, Primer, PU Foam 08:59 2 - Leveling Compound 13:17 3 - Preparing the OSB Panel Structure After Leveling 17:55 4 - Installing the Structure 22:07 5 - Installing the OSB Panels 32:12 Conclusion ************************************* My name is Flo, and Sandrine and I embarked on the self-build of our house.
