Installation Tips for Flooring in Humid Climates
Proper installation is crucial for any flooring in humid environments. Acclimating flooring materials to your home’s conditions for 48-72 hours before installation helps prevent future moisture-related problems. This allows the materials to adjust to the ambient humidity and temperature.
For wood-based products, leaving appropriate expansion gaps around the perimeter accommodates natural movement. Using moisture barriers or underlayments provides additional protection against moisture migration from subfloors.
When installing tile or stone, proper substrate preparation and waterproof membranes are essential. Using the right adhesives, grouts, and sealants designed for humid environments significantly enhances moisture resistance and longevity.
Before installing any flooring, test concrete subfloors for moisture using calcium chloride or relative humidity tests. Excessive moisture may require remediation before proceeding with installation.
