Koster Flooring Systems KOSTER VAP I 2000

Koster VAP I 2000 is a one-coat moisture vapor reduction system consisting of a unique combination of epoxy resins and other chemical compounds. Koster VAP I 2000 is formulated to prevent floor failures on concrete slabs containing elevated levels of moisture vapor emission. Koster VAP I 2000 has no upper limits for water vapor emissions; it resists high moisture levels (100% RH) and a sustained pH of 14.

Features
  • Due to its very high interlacing density, KÖSTER VAP I 2000 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.

Fields of Application
  • KÖSTER VAP I 2000 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
  • KÖSTER VAP I 2000 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.
Underlayments / Leveling Compounds
  • KÖSTER SL Premium is especially suited for installment on top of KÖSTER VAP I 2000.
  • Cementitious underlayments, leveling or skim coatings are not required over KÖSTER VAP I 2000 but are commonly used to smooth or level the KÖSTER VAP I 2000 coated surface in preparation for subsequent floor coverings and systems as required.
  • KÖSTER VAP I 2000 is not formulated to be a floor leveling product.
  • All underlayments, leveling or skim coats must be applied on top of the cured KÖSTER VAP I 2000 unless otherwise specified by your representative or the KÖSTER Technical Staff.
  • To guarantee proper adhesion of cementitious products to non-porous surfaces use KÖSTER VAP I 06 Primer prior to the installation of any cementitious material.
  • Do not install KÖSTER VAP I 2000 over any gypsum based products.
Adhesives
  • Most flooring systems and adhesives may be applied directly to the cured KÖSTER VAP I 2000.
  • Adhesives must be designed and formulated for use over a non-porous substrate.
  • There is no absorption of any fluid or solvents from the adhesive into the VAP I 2000 coated concrete.
  • Apply adhesives to a test area to check for compatibility prior to overall application.
  • Adhesives containing solvents (including water) that are not allowed to flash off prior to the flooring installation may be applied to a minimum of 4 mm of a cementitious underlayment.
  • Check with the manufacturer’s recommendation for installation over an underlayment and the required thickness for use as an absorptive blotter.
Application
  • The two components of KÖSTER VAP I 2000 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.
  • KÖSTER VAP I 2000 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.
