The versatility of our Duo Patch – our two-component, polymer modified concrete repair mortar – was on display on a project recently in Cardenas, Panama. Our distributor in the region, Construventas, S. A., partnering with Tecnova Panama, S. A. and coordinating with our SpecChem sales representative Roger Bellido, utilized SpecChem’s repair and restoration line to the tune of over 40,000 square feet of resurfacing, patching and repair.
Internal and external perimeter walls, along with floors, walkways, and other outside walls made up the majority of the project. Surface preparation on the walls was done using a manual surface grinder with both diamond discs and cutting discs for removal of any loose material and debris. SpecPatch – our general purpose, polymer-modified concrete repair mortar – was used first to repair damaged areas. Duo Patch was then applied throughout as a 3mm resurfacing coat.
Floors and walkways were handled similarly, using the surface grinders along with pressure washing to remove deteriorated layers to achieve the required surface profile. Duo Patch was then applied at thicknesses ranging from 3mm to 5mm, depending on the depth of repair and level required.
The project was a perfect opportunity to highlight the diversity of one of our strongest – and most versatile – repair and restoration products. In this case, Duo Patch was specifically selected for its uniform finish and natural concrete gray color, its flexible consistency, and its durability and adhesion.
