Territory Sales Representative from Merkrete submitted a com- plete installation system including Merkrete Hydro Guard SP-1 water- proofing, crack-isolation and air- barrier membrane, and 855 XXL LHT Mortar, a high-performance setting mortar, providing excellent non-sag characteristics for vertical stone applications in exterior con- ditions. This sole-sourced Merkrete installation system was submitted and approved by the architectural and design team atArchitects Design Group, and the Merkrete team was available as a resource for the project to answer any questions or address concerns relating to the installation system as recommended from Merkrete. The specifications called for crack-isola- tion, waterproofing and air-barrier on the exte- rior parts of installation to meet the new FEMA FIRM map elevations, as well as updated code that required wind and impact-resistant design. Combined with an aggressive project sched- ule, work began using Merkrete Hydro Guard SP-1. The liquid-applied, fast-drying Hydro Guard SP-1 combines crack isolation up to 1/8” and a waterproof system to enable crews to prepare the substrate for setting tile at a faster pace. Hydro Guard SP1 contains excellent elongation, adhesion and high-strength properties providing a 100% waterproof membrane that prevents the transfer of substrate cracks to the finished ceramic or stone tile surface. “Merkrete’s liq- uid membranes have been a staple FEATURE: Merkrete Systems provide protection to Naples Fire-Rescue Station Exterior protected using Merkrete’s Hydro Guard SP1 Waterproofing & Crack Isolation Membrane. 54 TileLetter | July 2019
