Transform Your Home with Perfect Vinyl Flooring: Master the Art of Subfloor Preparation for Lasting Beauty
When it comes to installing vinyl flooring, the foundation beneath your feet matters just as much as the beautiful surface you see. Luxury vinyl flooring must always be installed on a perfectly smooth and even surface, as subfloor works are imperative because if the subfloor is not good, the finished look will not be good either. Whether you’re working with concrete or wood substrates, proper subfloor preparation is the key to ensuring your vinyl flooring investment delivers years of stunning performance.
Understanding Your Subfloor Foundation
Vinyl is one of the few types of floors that can be safely installed over concrete, wood, or other solid floors. However, each substrate type requires specific preparation techniques to achieve optimal results. A subfloor is the surface underneath the new flooring to be laid or installed and serves as the foundation on which the new flooring will stand.
Concrete Subfloor Preparation: The Essential Steps
Concrete substrates present unique challenges that require careful attention to detail. If your concrete subfloor was just poured, you’ll need to allow it to properly cure for a minimum of 60 days before your luxury vinyl flooring installation begins.
Moisture Testing and Control
The most critical aspect of concrete preparation is moisture management. Most commonly, the maximum moisture condition is 3.0 pounds per 1,000 sq. ft. per 24 hours when tested with the Rubber Manufacturers Association test. A simple DIY test involves taping a piece of your scrap vinyl to the floor using duct tape and checking after 72 hours—if it pulls up easily, moisture levels are too high.
Floating vinyl flooring will require a vapor barrier upon installation on a concrete subfloor. This crucial step prevents moisture from compromising your flooring investment over time.
Surface Preparation and Leveling
Once moisture is controlled, focus shifts to creating a perfectly smooth surface. Check your subfloor to make sure it is level by testing multiple areas using a large level and noting any low or high spots. If you find any low spots, smooth them over using a floor patching compound, follow the instructions on the compound and then let it dry for at least 20 minutes.
Wood Subfloor Preparation: Building the Perfect Base
Wood substrates require a different approach but are equally manageable with proper technique. When you install your vinyl on a wood subfloor, the top plywood should be a minimum of 1/4″ thick. However, professional installers often recommend going thicker for optimal results.
Adding Underlayment for Stability
The goal is to have a wooden subfloor consisting of two layers at least 1-inch thick. This involves installing additional plywood over your existing subfloor. Do NOT line up the second layer with joints in the first layer, and make sure you give yourself at least a quarter inch gap along the walls and between each joint so the wood can expand naturally.
Proper fastening is crucial for long-term performance. Secure the plywood with 1-inch deck screws, with screw-heads falling just below the surface of the wood. Cover the gaps between the screw heads and joints with floor patching compound and allow it at least 20 minutes to dry before sanding it down.
Moisture Considerations for Wood
Wood substrates also require moisture monitoring. Verify that there are no signs of insect or mould growth and that the wood’s moisture content is no more than 10%. This ensures your vinyl flooring will perform optimally without warping or other moisture-related issues.
Professional Standards and Tolerances
Industry standards are strict for good reason. The general ASTM requirements for any resilient flooring are no more than 3/16″ in a 10′ span in any direction or no more than 1/8″ in a 6′ span over any wood or concrete substrate. These tolerances ensure your vinyl flooring will lay flat and perform as intended.
