BestCrete PU 500SR

BestCrete PU500 SR has a medium-textured anti-slip surface, making it suitable for application in wet areas. Its dense structure and waterproofing properties make it an ideal finishing floor coating system for:

• Food and beverage factories.

• Pharmaceutical and medicine manufacturing plants.

• Chemical plants.

• Seafood processing factories, cold processing areas, and cold storage rooms.

• Heavy impact industrial workshops, etc.

• Withstands extreme temperatures up to 150°C.

• Excellent anti-slip performance, even when the floor surface is wet.

• Highly durable, capable of withstanding heavy loads, abrasion, and severe mechanical impact.

• Excellent chemical resistance.

• Fast return-to-service time.

• Effectively inhibits the formation of bacteria and mold.

• Solvent-free, contamination-free, ensuring indoor air quality with zero VOC emissions.

• Considered a sustainable flooring system with long product lifespan and extended service life.

SURFACE PREPARATION:

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

• The substrate surface must be flat, dense, dry, and mechanically prepared by grinding or shot blasting before application of BestCrete PU500 SR.

• Cracks and defective areas must be properly treated, repaired, and patched according to procedure. All contaminants, debris, and dust must be thoroughly cleaned.

• If the substrate is metal, oil stains and rust must be completely removed and cleaned using BestThinner SC01.

APPLICATION PROCEDURE:

Coating System:

• One primer coat of BestCrete PU500 SL with thickness ~ 1 mm.

• One finishing coat of BestCrete PU500 SR with thickness as required by the design.

Note:

• BestCrete PU500 SR industrial flooring is highly tolerant to residual substrate moisture and can be directly applied on 7-day-old new concrete, or on sound existing old concrete with high moisture content without primer if a waterproof membrane exists within the structure.

• Epoxy damp-proof membranes (DPMs) should not be used because they soften under high temperature conditions and may lead to floor failure.

Mixing:

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

Note: Partial mixing is not recommended. Always mix the entire pre-packaged set.

Application:

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

Note: BestCrete PU500 SR must be applied by professionally trained applicators certified by the manufacturer.

CLEANING:

• Use a dry cloth and BestThinner SC01 for cleaning before the product hardens.

SAFETY INSTRUCTIONS:

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

• 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 and household utensils. Keep out of reach of children.

• Dispose of excess material in accordance with local regulations.
