- Ready-to-Use Product Features
- Features
- Due to its very high interlacing density, the product is able to reduce the accumulation of water vapor to such an extent that synthetic resin coatings, synthetic resin adhesives and plastic coverings are not pushed off the substrate.
- The material displays a good resistance to water, sewage, mineral oil, salt solutions, and diluted acids.
- Works with virtually all types of flooring.
- Unique combination of epoxy resins.
- Very low permeability.
- Resists moisture levels up to 100% RH.
- VOC Free.
- Resists sustained pH of 14.
- Fast track application.
Applications & Uses

- Compatible Substrates & Surfaces
- Fields of Application
- This product is a special resin for application on unsealed interior concrete floors such as industrial and multi-purpose halls, offices, hospitals, schools, supermarkets, manufacturing facilities, airplane hangars, storage and retail space, and commercial and residential construction which is exposed to moisture from the underside due to faulty or missing waterproofing of the concrete.
- It protects against high concrete alkalinity (pH 13 - 14) and serves as a primer by reducing the water vapor diffusion prior to the application of epoxy or polyurethane resin coatings or respectively the adhesion of vapor tight floor coverings such as PVC, rubber, wood, and solid backed carpet.
- Substrate
- This product is used to seal concrete surfaces.
- The minimum age of the concrete surface to be sealed must be 7 days.
- The surface to be sealed must be clean, absorbent, free of dust, oil and grease and other adhesion-reducing substances.
- Any kind of surface contamination like adhesives, coatings, curing compounds, efflorescence, dust, grease, oils, etc., have to be removed completely by shot blasting.
- Smooth concrete surfaces must be roughened by sand or shot blasting.
- The substrate must have a minimum adhesive tensile strength of 1.5 N/mm².
- During application and curing the surface must have a minimum 3°C above the dew point.
- The concrete must be free of alkali sensitive aggregates, and the surface free of water soluble silicates as often found in surface hardeners, sealing agents, and crystalline waterproofing products.
- Application
- The two components of this product are mixed using an electrical stirring device below 400 rpm until a homogeneous consistency is achieved.
- To avoid defects due to insufficient mixing, repot the material and mix it again.
- This product is applied evenly with a roller or squeegee in one coat.
- The formation of puddles must absolutely be avoided.
- Concrete surface profile, absorption rate and moisture vapor rates can effect coverage requirements.
- The substrate must be completely covered with a glossy film.
- The minimum continuous layer thickness is 0.4 mm.
- If a second coat is necessary to achieve the minimum layer thickness, it is to be applied between 12 and 24 hours after the first coat.
- After a waiting time of min. 12 hours, subsequent work steps such as the application of sealants, coatings or coverings can be carried out.
- In order to avoid air entrapment, use only solvent free or respectively water free adhesives.
- Cleaning
Clean tools immediately after use with KÖSTER Universal Cleaner.
- Other
- Liquid polymers react to temperature fluctuations by changing their viscosity and/or curing behavior.
- Application should only be carried out during falling or constant temperatures.
- Low temperatures will slow the reaction; high temperatures and mixing large volumes will increase the reaction rate.
- Protect the coating form moisture of all kinds during application and curing.
- Coverage
approx. 300 - 500.
