PINKOW

Thin-layer Concrete
Polymer-modified

polymeric Thin-layer concrete is a flooring system engineered for high mechanical strength and superior adhesion. Designed to be applied in thin layers ranging from 10 to 30 millimeters, it is installed over existing concrete substrates using a power trowel. Our expert installation team handles the entire process, from substrate preparation to surface finishing.

introduction

PINKOW polymeric thin-layer concrete is a composite material made of modified cements, reinforcing polymers, hard aggregates, mineral pigments, and approved additives. Designed as a flooring solution with high mechanical strength and adhesion, it is applied in thicknesses ranging from 10 to 30 millimeters. This product is applied over existing substrates or concrete using a trowel and is ideal for applications where a thin, durable, and aesthetically pleasing surface is required.

polymeric thin-layer concrete can be applied in thicknesses ranging from 10 to 30 millimeters in a single layer directly onto old concrete. By finishing with a power trowel, a seamless and impermeable surface can be achieved, making it suitable for both industrial and decorative environments.

This product exhibits high adhesion and resistance to compression, bending, and abrasion. Given the expectation of high durability, it should be subjected to a 21-day immersion test in water and other methods to prevent sudden water expulsion.

Additionally, after the substrate is completely dry, a specific coating (L3 sealer) can be applied and polished to achieve a glossy, light-reflective surface with higher abrasion resistance.

The PINKOW polymeric thin-layer concrete is similar to the BAUFLOOR® ENDURO Thin-layer product.

Polymer properties

Economic substitution

Thin-layer concrete is a product that can be applied directly onto old concrete surfaces and finished using a power trowel.
Given its thin application thickness and consequently low weight, this product is ideal for renovation and lightweight construction projects.
It serves as an alternative to traditional concrete pouring and flooring methods in projects with height limitations.
It enables the modernization of factory floor coverings without the need to relocate machinery, resulting in significant time and cost savings.
It replaces the need for re-flooring old substrates and eliminates the requirement for demolishing existing floors due to its high strength and thin thickness.
It saves time and costs associated with shutting down production lines for floor renovations.
It saves time and the costs of concrete demolition and transporting the resulting waste.
The resulting surface is exceptionally strong and significantly harder than dry-shake hard concrete and mortar due to its monolithic nature and polymeric composition.
The product offers a wide range of aggregate colors, can be polished, and the aggregates can be exposed through grinding, allowing for repeated surface renovations.
It prevents cracks from the existing floor from transferring to the new surface.
It can be used for renovating parking lot floors, sidewalks, and as a base for resinous floor coverings like epoxy and polyurethane.
By applying special sealants and polishing, the surface can achieve the appearance, abrasion resistance, and impermeability of natural stone.

Floor covering for special conditions

PINKOW polymeric Thin-layer concrete is a high-performance solution for flooring applications. Its exceptional mechanical strength, abrasion resistance, and reduced thickness make it a superior alternative to traditional thick concrete slabs. The power trowel finish ensures a smooth and durable surface, ideal for industrial settings.

Method of use

First, weak areas of the substrate are removed to ensure a firm and solid surface. Then, using a specialized grooving machine, the surface is grooved so that the substrate acts like a nail bed, preparing it for the application of thin-layer polymer concrete.
Grooving the surface can be performed in several ways, with the aim of increasing the adhesion of the thin-layer polymer concrete to the surface and improving control of the mortar shrinkage.
After grooving the surface, it is cleaned with a high-pressure water jet to remove any grease, dust, or contaminants.
In the next step, the thin-layer polymer concrete powder is mixed with a specific percentage of water (approximately 1% of the powder weight) using a mixer. The prepared mortar is poured onto the substrate and after a specified time, the surface is finished using a power trowel.
The finished surface is cut at regular intervals with a cutter for up to 84 hours to control cracking.
To achieve a high-quality flooring in terms of compressive, flexural, and abrasion resistance, curing and avoidance of heavy traffic must be carefully performed for up to 12 days.

Final word

Achieving a top-tier industrial concrete flooring requires meticulous planning, coordination, and control. The concrete mix must be of the highest quality, and the delivery schedule to the job site must be closely monitored and consistent. Environmental conditions significantly impact the concrete surface moisture, subsequently affecting the application and quality of the final product. The stages involved in spreading the concrete using specialized equipment must be precisely timed. Finally, the proper execution and finishing of the concrete are crucial for attaining a high-quality final surface.

An experienced industrial hard concrete flooring contractor who understands the nuances and intricacies of concrete installation and the use of appropriate equipment plays a pivotal role in producing a quality product. Professional contractors employ a quality control system.
