Laying Wood Flooring On New Concrete

Laying Wood Flooring On New Concrete: A Comprehensive Guide

Installing wood flooring over new concrete requires specific considerations to ensure a durable and aesthetically pleasing result. Here's a comprehensive guide to help you navigate this process:

Moisture Content:

Concrete contains moisture, which can damage wood flooring if not properly addressed. Use a moisture meter to measure the concrete's moisture content; it should be below 12% for successful installation.

Vapor Barrier:

A vapor barrier is essential to prevent moisture rising from the concrete into the flooring. Install a plastic sheeting with an overlap of at least 6 inches, taping the seams securely to create a complete seal.

Subfloor Preparation:

The concrete surface should be level, dry, and smooth. Fill any cracks or uneven areas with a cement-based self-leveling compound. Sand any rough spots or protrusions.

Underlayment:

An underlayment provides additional moisture protection, reduces noise, and improves the feel underfoot. Choose an underlayment specifically designed for use over concrete, such as a cork or foam underlayment.

Wood Species and Planking:

Select a wood species suitable for high-moisture environments, such as engineered wood or moisture-resistant hardwood. Consider the width and thickness of the planks, as narrower and thicker planks are generally more resistant to moisture.

Acclimation:

Allow the wood flooring to acclimate to the temperature and humidity of the room for several days before installation. This will help the wood expand and contract naturally, preventing gaps or buckling.

Installation:

Follow the manufacturer's instructions for the specific type of wood flooring you are using. Generally, the flooring is glued or nailed directly to the underlayment.

Expansion Gap:

Leave an expansion gap around the perimeter of the room to allow for natural movement of the flooring. Use spacers or molding to ensure a consistent gap.

Finishing:

Once the flooring is installed, it should be sanded, stained, and sealed. Use a moisture-resistant polyurethane sealant to protect the floor from moisture and wear.

By following these steps, you can successfully install wood flooring on new concrete, creating a beautiful and durable foundation for your home.
