Subfloors and Preparation
Half the battle
You can have the most expensive, most durable, most beautiful floor selected, but if you haven’t figured out how much prep work your floor will require, you could be setting yourself for failure. Here are a few things to look for.
Deflection: How much your subfloor moves when a load or force is applied to it. It has to do with how thick your subfloor is in addition to how far apart your floor joists are positioned. The less deflection you have, the better.
RH: Relative Humidity is the amount of water vapor in the air expressed as a percentage of what it would require to be saturated at that temperature. Generally, as temperature goes up, humidity goes down. Too little or too much humidity can destroy hardwoods and severely damage most types of flooring or create health risks.
Levelness: How flat your substrate is when measured using a 10′ straightedge. You don’t want deviations from the manufacturer’s recommended settings, as it could lead to floor failure. With vinyl planks, you could have hollow spots that could break or mark up through the vinyl. With tile, it could leave you hollow spots which are susceptible to breaking under load. For a long lasting floor with a good warranty, self leveling and grinding are typically how we fix those issues.
