The treatment of base concrete is the key to making a good polyurethane concrete floor. In order to enhance the adhesion between the base and the floor, mechanical treatment is required to expose concrete aggregates (such as shot blasting). The floor surface must be grooved, with the depth and width of the groove being 2-3 times the thickness of the polyurethane mortar floor.
Mix the SPR-23101P polyurethane universal self-leveling mortar material evenly according to the design ratio. Strictly control the filling of each groove and gap. After mixing, use a trowel to continuously pave it. This step cannot be interrupted to ensure better adhesion. A primer thickness of 1mm is suitable.
After solidification of the polyurethane mortar primer, it is necessary to grind the rough primer with a grinder to increase the adhesion between subsequent coatings.
Evenly mix SPR-23101P according to the proportion using a low-speed double-head or spiral blade mixer. Use a nail rake to evenly spread the material, use a spatula to pave, and use a defoaming roller to roll back and forth. This step must be completed as soon as possible to ensure surface quality.
