Subfloor Prep: The Key to a Good Floor

No matter how resilient the type of flooring you select is, it is important to support it with a strong subfloor. It’ll ensure the overall performance of the floor itself, as well as prevent any damage or leaving you with an uneven surface. We’ve put together a subfloor guide to help you better understand how important a sound subfloor is for your next flooring installation.

Before you begin the installation process, ask yourself, what type of flooring are you installing? Take a look at our warranty guide for hard and soft surface flooring for up to date information about which would be best for your home. Next, are you doing a new installation or a remodel? And finally, what condition is your subfloor in? You want to make sure your subfloor has five things, dry, level, structurally sound, clean, and smooth. If your subfloor is missing any of these, then you may need to take extra steps to ensure it meets the standards.

When preparing your subfloors, the foundation must be solid. That means they need to be dry, sound, and flat. Moisture content refers to the amount of moisture held within the product. Most subfloors in Hawaii are concrete, and concrete floors hold moisture. The subfloor should be dry prior to installation. To determine how much moisture is in the floor, use a moisture meter. For every 1,000 square ft., a minimum meter reading of 20 in subfloor is recommended by the National Wood Flooring Association, while concrete's moisture content should not exceed 4%.

Waterproof Flooring Options

Since we are in a tropical climate, we recommend choosing flooring that is either water resistant or entirely waterproof. We offer luxury vinyl brands like Pacifica by COREtec and Karndean Looselay.
