BestCrete PU 500SL

BestCrete PU500 SL is designed for floors requiring high chemical resistance together with a flat, smooth finished surface for easy cleaning and maintenance.

Typical areas of application include:

• Textile factories and film studios.

• Food and beverage industries.

• Warehouses and storage facilities.

• Confectionery factories.

• Electronics assembly and manufacturing plants.

• Pharmaceutical industries.

• Chemical plants.

• Excellent durability, capable of withstanding heavy loads, abrasion, and severe impact.

• Compliant with hygienic standards for food, pharmaceutical, GMP, and HACCP applications.

• Seamless, oil-resistant, stain-resistant surface allowing easy cleaning, maintenance, repair, and patching.

• Excellent chemical resistance.

• Fast return-to-service time.

• Effectively inhibits the formation of bacteria and mold.

• Recognized as a sustainable flooring system with long service life and prolonged operational durability.

SURFACE PREPARATION:

• If the substrate is concrete, the compressive strength must be ≥ 20 MPa, tensile strength ≥ 1.5 MPa, and suitable for the actual service load of the floor.

• The floor substrate must be level, dense, dry, and mechanically prepared by grinding or shot blasting before applying BestCrete PU500 SL.

• Cracks, defective areas, and damaged spots must be properly treated, repaired, and patched in accordance with standard procedures. Dust, debris, and loose particles must be thoroughly cleaned.

• If the substrate is metal, all grease stains and rust must be completely removed and cleaned with BestThinner SC01.

APPLICATION PROCEDURE:

Coating System:

• One suitable epoxy- or polyurethane-based primer layer, or one primer layer of BestCrete PU500 SL with thickness approximately 1 mm.

• One topcoat layer of BestCrete PU500 SL with thickness as required by design.

Note:

• BestCrete PU500 SL industrial flooring is highly tolerant to residual substrate moisture and can be applied directly onto 7-day-old green concrete or onto sound old concrete with high moisture content without requiring a primer, provided that a waterproof membrane exists within the slab structure.

• Epoxy damp proof membranes (DPMs) should not be used because they tend to soften under high temperature conditions, which may result in floor failure.

Mixing:

• Premix Component A, then add Component B and mix thoroughly. Add Component C (according to the specified ratio) and mix using a low-speed mechanical mixer or paddle mixer (300 – 500 rpm) until homogeneous. Total mixing time should be approximately 1 minute 30 seconds to 2 minutes.

Note: Do not split the pack into smaller quantities; always mix the full pre-packed unit.

Application:

• Pour the mixed material onto the corresponding substrate area in successive strips approximately 180 ÷ 200 mm wide. Immediately use an appropriate notched trowel to spread and compact the material evenly to the required thickness, then use a specialized roller to assist compaction and create a uniform finished surface.

Note: BestCrete PU500 SL must be installed by professionally trained applicators certified by the manufacturer.

CLEANING:

• Use a dry cloth and BestThinner SC01 to clean tools and equipment before the product hardens.

SAFETY INSTRUCTIONS:

• BestCrete PU500 SL may cause allergic reactions to sensitive skin after prolonged contact. Protective gloves, masks, and safety goggles should be worn during application.

• In case of contact with eyes, nose, or mouth, rinse immediately with plenty of clean water several times before going to the nearest medical center for timely and proper treatment.

• Avoid contact with food, household utensils, and keep out of reach of children.

• Dispose of excess material in accordance with local regulations.
