Isocheck Primo High Load is applicable over existing floorboards on traditional and composite steel and timber joist floors. 

• all invasive fittings must be properly treated;
• all structural wall should be sealed;
• the sub-floor, which must be clean and dry, should be covered with proper insulation layer consisting of mineral wool insulation, added between the floor joists;
• the entire structure needs to be watertight;
• the product must be kept and stored in dry conditions.

Installation should begin with at the furthest point from the entrance, while the decking must follow a stretcher-bond pattern. The boards are pushed over the joints which have been treated with a proper adhesive added both on top of the tongue and bottom of the groove. It is advised that stud partitioning should be built from the sub floor and that flanking strips should be added for improved insulation performance of the walls and floors. Once the entire system has been installed, the boards should be protected from potential damage with a proper finish layer added on top. All skirting must be isolated from the floor surface and new ceiling boards installed prior to installing the system, in order of avoiding potential flanking transmission.
