Moisture penetration through concrete slabs can cause severe problems for subsequent flooring systems.
High concentrations of moisture and alkalinity (levels determined through testing) can lead to the deterioration of flooring adhesives and delamination of coatings by osmotic action. Even with relatively low moisture emissions (MVER), elevated alkalinity can compromise even the toughest flooring system adhesives. To avoid this problem, the concrete slab should be primed with a material that will tightly bond to the concrete under these very adverse conditions.
KÖSTER VAP I 2000 is a special material which fulfils all of these functions; it has very low permeance ASTM E96 wet: .04–.09, excellent bonding characteristics and is resistant to sustained high alkalinity (pH of 14). The KÖSTER VAP I 2000 vapor reduction system is applied to shot blasted, solid concrete substrates that are free of bond inhibiting substances.
After curing, a covering layer (i.e. KÖSTER LF-VL) or any other type of final flooring may be applied. If an underlayment is required use KÖSTER SL Premium together with KÖSTER VAP I 06 Primer on top of the moisture mitigation system.
Always adhere to the specifications in the respective Technical Guidelines.

KÖSTER LF-VL
Floors in industry and production facilities are subjected to a multitude of stresses, especially mechanical stresses through forklift traffic, machines, or shocks through falling objects.
Concrete floors subjected to such stresses are covered with the industrial floor coating KÖSTER LF-VL.
KÖSTER LF-VL is a solvent free, self-leveling and pigmented floor covering for industrial uses with a high abrasion resistance.
The substrate must be prepared, dry, clean, and freed of all bond inhibiting substances. It is then primed with KÖSTER CT 121 or, when moisture is present in or below the slab, with KÖSTER VAP I 2000; and broadcasted with quartz sand.
The top layer can also be adjusted for various slip resistance classifications by broadcasting it with kiln dried silica sand or various top coats. The application of KÖSTER LF-VL can then follow as a thin layer to create a slip resistance or in various millimeter thicknesses. The complete system can be installed with low emission materials according to the AgBB guidelines and can therefore be installed in critical interiors such as schools or hospitals.
Always adhere to the specifications in the respective Technical Guidelines.

In areas where electronics are manufactured or in areas that can be electrostatically charged by people or machines, the floor must have a sufficiently high electrostatic dissipation to eliminate the risk of damage. For these environments, ESD protection areas are required (ESD: Electrostatic Discharge), where special ESD coatings are installed.
The KÖSTER ESD System has a structure that provides maximum protection against unwanted electrical charges. The product system consists of the conductive layer KÖSTER ESD 175, which is a solvent free epoxy resin dispersion that is simply applied with a roller. After only two hours, it is cured and can be connected to the building grounding with the adhesive copper tape KÖSTER ESD 476.
Afterwards, the solvent free, self-levelling coating KÖSTER ESD 275 is applied as the top coat. After cure it not only protects the concrete from chemical and mechanical stresses, it also maintains the high electrostatic dissipation required for an ESD protected area. The KÖSTER ESD System has been tested according to DIN EN 61340-4 by the KIWA Polymer Institute Ltd. The excellent test results allow the KÖSTER ESD System to be used in rooms with very high requirements.
Always adhere to the specifications in the respective Technical Guidelines.

Parking garages and trafficked areas have especially high requirements on coatings. The KÖSTER OS 8 System is a highly resistant, easy to apply solution.
Surface preparation is critical and should result in a clean, dry surface free of all bond-inhibiting materials. KÖSTER CT 121 mixed with Quartz Sand 0.06 – 0.36 mm (1:1) is used as a primer and applied with a standard trowel. Immediately afterwards, the primed surface is broadcasted with Quartz Sand 0.4 – 0.8 mm. Through the broadcast with quartz sand, the mechanical resistance is increased and a higher slip resistance is achieved.
After excess Quartz Sand has been removed, the top coat consisting of the solvent-free KÖSTER CT 221 is applied. The KÖSTER OS 8 system has been tested according to the DIN EN 1504-2 guideline and fulfills the supplementary standard DIN V 18026.

KÖSTER UC 300
KÖSTER UC combines properties of mineral floor leveling materials (leveling and repair of mineral substrates) and reactive resin coatings (protection against penetrating substances and damage as well as decorative design) in one product. It is based on a polymer binder (polyurethane) and mineral fillers. KÖSTER UC Systems can therefore be used in a wide variety of fields of application with high demands on the coating, such as in the food production industry (production, kitchens), as well as in chemical and pharmaceutical industries. KÖSTER UC can be installed in new construction projects (retail) and in the renovation of production areas which must be quickly open to traffic.
In order to ensure a successful application, the substrate must be properly prepared by shotblasting. The three-part KÖSTER UC System is made up of: KÖSTER UC 100, a self-leveling urethane cement flooring system for layer thicknesses between 3 and 9 mm; and KÖSTER UC 300, a very thin-layer urethane cement flooring system, which can be used as a primer or top coat, depending on the circumstances. Additionally, KÖSTER UC Pigment Paste can be used to color any of the KÖSTER UC flooring system to meet decorative requirements.
Always adhere to the specifications in the respective Technical Guidelines.

KÖSTER CT 228 Flex
KÖSTER CT 228 Flex is an advanced epoxy coating designed for protecting concrete and steel surfaces. When applying to vertical surfaces it is mixed with 6% KÖSTER KB-Pox Thickening Agent. It is ideal for use in industrial and agricultural settings, such as wastewater treatment and biogas plants, and is also highly effective for safeguarding heavily loaded industrial floors. When higher slip resistance beyond R9 is necessary, KÖSTER CT 228 Flex can be textured with kiln-dried broadcast materials or used as a scratch coat by incorporating kiln-dried fillers. Additionally, it serves as a chemically and mechanically resilient top sealer for epoxy resin compounds or as a top coat for thick-layer surface protection in high-traffic areas.
For concrete substrates the surface must be dry, clean, and free from loose particles. Preparation involves mechanical methods such as shot blasting or grinding, followed by vacuuming to ensure a dust-free surface. Any significant surface roughness can be treated with a scratch coat primer or an epoxy resin screed, using products such as KÖSTER CT 121 or KÖSTER leveling compounds (e.g. KÖSTER SL Protect, KÖSTER SL Premium, or KÖSTER SL Flex). Cracks in the concrete should be sealed with KÖSTER KB-Pox IN and broadcast with kiln dried quartz sand as needed. For wall areas, sandblasting is recommended to achieve a rough, clean surface. A single layer of KÖSTER CT 228 Flex is applied.
For steel substrates the surfaces must be dry, clean, and free of oil and grease. Preparation should meet DIN ISO 12944-4 standards, with blasting to at least SA 2 ½ purity and a mean roughness of at least 50 μm, or manually with a steel brush to SA 3. Weld beads and seams must be removed, and edges smoothed by grinding. Optionally revisions can be made with KÖSTER CT 228 Flex, again incorporating 6% KÖSTER KB-Pox Thickening Agent. Finally, all dust and residues must be thoroughly removed to ensure a clean surface ready for coating. Two layers of KÖSTER CT 228 Flex are applied to ensure optimal protection.
