SpeedFloor - SUBSTRATE PREPARATION
Surface grinding and milling
One of the simplest, basic ways to prepare the substrate that requires it is milling and/or grinding its surface. These actions allow you to remove detached, loose fragments of the substrate. And if it is necessary (e.g. in the case of planning to make leveling layers or gluing the surface), cleaning its surface from dirt and old coatings. This is the easiest and fastest way to level the ground in a coarse range. It can also be a way to restore mineral floors before applying protective coatings.
"Sewing" concrete, supplementing the surface
Sometimes the ground has visible scratches, cracks and clear cracks, and its surface has serious deficiencies and cavities. If it is load-bearing and durable in itself, it can be repaired on an ad hoc basis. The cracks will be filled with filling compound (resin or PCC) by attaching steel clamps across it to support stabilization. Deficiencies in the surface of the substrate can be repaired by filling them with a repair compound selected according to the type of substrate, the size of the deficiencies and the size of the loads that will occur later. It often turns out that these activities are enough to go to the stage of assembly of various SpeedFloor surfaces. Sometimes this is only the next stage of revitalization of the substrate, e.g. before making leveling layers.
Equalization layers
It happens that the surface of the ground has so many defects in its structure or different heights of its individual areas that local supplementation and levelling would be very time-consuming and not very economical. In such situations, the best solution is to use levelling compounds. They must be properly selected. First of all, in terms of strength, thickness range of application or drying time. The terms of the application are also important. Properly made levelling and reinforcing layers, sometimes with “reinforcement” with a special PE mesh, constitute a solid substrate for the installation of finishing layers.
