Polyurethane universal self-leveling mortar is a four component color water-based self-leveling mortar floor coating made with high-performance polyurethane resin as the base material, and special cement, graded silica sand, and active pigments as the aggregates; Excellent impact resistance, damage resistance, chemical resistance, and scrub resistance
Base Surface Treatment
The treatment of base concrete is the key to making a good polyurethane concrete floor. The quality of ground treatment directly affects the service life of the 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; In particular, all edges (such as trenches, etc.) should be grooved at a distance of 20mm;
Primer Application
After the base surface is cleaned, mix the SPR-23101P polyurethane universal self-leveling mortar material evenly according to the design ratio, pour another bucket for mixing again, and then use the scraping and coating method for batch scraping construction. Strictly control the filling of each groove and gap. After mixing the material, use a trowel to continuously pave it. This step cannot be interrupted, and needs to be completed as soon as possible to ensure better adhesion of the material. To ensure that the base layer is completely sealed, a primer of polyurethane on a thickness of 1mm is suitable;
Grinding After Solidification Of The Primer
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;
Construction Of Polyurethane Mortar Surface Coating
evenly mix SPR-23101P polyurethane universal self-leveling mortar according to the proportion (using a low-speed double-head or spiral blade mixer), pour another bucket for mixing again, use a nail rake to evenly spread the material according to a certain thickness, use a spatula to pave, and use a defoaming roller to roll back and forth. After mixing the material, continue to apply it. This step cannot be interrupted, and needs to be completed as soon as possible, To ensure better surface effect and adhesion.
