What are some common problems with COREtec flooring?

Common problems with COREtec flooring include denting with heavy furniture, scratching with pets and abuse, gapping with temperature changes, and installation issues if subfloor not flat, though overall satisfaction is high as COREtec is top-rated LVP. COREtec Original and Plus feature rigid core luxury vinyl plank that is durable, but can dent with heavy furniture without felt pads, as rigid core is not as hard as hardwood and heavy point loads can cause dents, costing 3 to 6 dollars per square foot materials. Scratching can occur with large dogs, dragging furniture, and abrasive dirt, especially on darker colors that show scratches more, though 20 mil wear layer resists normal scratches. Gapping and expansion can occur if installed without proper expansion gap or if temperature changes significantly, as COREtec can expand and contract slightly, requiring 1/4 inch expansion gap around perimeter per installation instructions. Installation problems include click-lock breaking if subfloor not flat within 3/16 inch over 10 feet, requiring subfloor leveling. Some complaints about cork underlayment compressing over time. After installation, some owners report hollow sound if subfloor uneven. Compared to Shaw Floorte Pro and Mohawk SolidTech, COREtec has similar problems. Overall, COREtec problems are similar to other LVP brands and often due to improper installation or lack of felt pads, not manufacturing defects, with high owner satisfaction.
