Question Answer
Frequently Asked Question
Florida's high humidity and temperature fluctuations demand exceptional subfloor preparation for large format installations. Technical standards require maximum allowable deviation of 1/8" in 10 feet (twice as stringent as standard installations), with mandatory moisture vapor testing showing maximum 3 lbs/1,000 sq ft/24 hrs on calcium chloride tests. Additionally, crack isolation membranes rated for minimum 1/8" movement are required throughout, with specialized edge isolation at all perimeters. These enhanced requirements add $8-$15 per square foot to installation costs but prevent the catastrophic failures common in Florida's challenging environment where substrate movement is exacerbated by unstable soil conditions and seasonal moisture variations.
Technical requirements increase exponentially with tile size. While 24"×48" formats require 95% mortar coverage and specialized edge-leveling systems, 60"×60" and larger formats demand 100% coverage achieved through specialized back-buttering techniques, mandatory dry-laying before installation, and multi-person placement teams. Additionally, mortar selection becomes increasingly critical with larger formats, requiring extended open time (minimum 4 hours in Florida's humidity) and enhanced flexibility to accommodate the increased risk of lippage and cracking. These technical demands explain why installation costs increase approximately 15-20% with each substantial increase in tile dimension.
Large format installations in Florida's luxury market require specialized equipment including vacuum-assisted lifting systems ($3,500-$5,500), diamond bridge saws ($6,500-$9,500), and mechanical lippage control systems ($1,800-$3,200).
