Yes, in many cases, you can install engineered wood flooring directly over floorboards. However, there are a few important considerations to keep in mind.

First, the floorboards must be in good condition and level. Any warped or damaged boards should be replaced before installation. Additionally, the boards should be properly secured to the subfloor to prevent any movement or squeaks.

Second, a suitable underlayment should be used to provide a smooth and stable surface for the engineered wood flooring. This can include a foam or cork underlayment or a layer of plywood or OSB.

Finally, it’s important to follow the manufacturer’s installation instructions and recommendations for the specific type of engineered wood flooring being installed. With proper preparation and installation, engineered wood flooring can be a durable and attractive option for installation over floorboards.
