Project features：

Polyurethane heavy-duty anti-slip mortar is a four component color water-based self-leveling mortar floor coating made of high-performance polyurethane resin as the base material, and special cement, graded silica sand, and active pigments as the aggregate; Excellent impact resistance, damage resistance, chemical resistance, and scrub resistance; Capable of withstanding heavy loads and a high degree of slip resistance.

Construction process：

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 polyurethane primer of 1 mm 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.

Sanding construction for the middle layer

Mix the SPR-23101P polyurethane universal self-leveling mortar material evenly according to the design ratio, pour another bucket for mixing again, use a nail rake to evenly spread the material according to a certain thickness, and then sprinkle quartz sand.

Surface layer construction

Evenly mix the SPR-23104P polyurethane heavy-duty anti-slip mortar according to the proportion (using a low-speed double-head or spiral blade mixer), pour another bucket and mix again. After that, evenly spread the material with a trowel according to a certain thickness, pave it with a trowel, and continuously pave the material after mixing. This step cannot be interrupted, and needs to be completed as soon as possible to ensure better surface effect and adhesion.

Scope of application：

low-temperature freezer, high-temperature decontamination area, boiling water and scalding operation room; Areas such as frying rooms, slaughterhouses, and treatment areas that have oil, water, high temperatures, and require a high degree of slip resistance; Areas requiring high temperature hot water vapor pressure flushing.
