Moisture Control Systems
Concrete is one of today's most important
building materials. Mostfloorslabs are made of
concrete. While concrete itself is permeable to
moisture vapor, many modern flooring systems
have very low moisture permeability and are
susceptible to problems caused bymoisture vapor.
The moisture control systems manufactured by
K65TER are designed to be applied on concrete
to supress moisture vapor and the problems
associated with it.
Why is moisture vapor an issue?
Flooring failures due to water vapor in concrete
floor slabs have been plaguing the construction
industryfor decades, causing millions of dollars in
damage to our economy. Typical damage patterns
indicating a serious failure of the flooring
system can be blisters in epoxy coatings, bubbles
in sheet goods, unsightly staining at seams,
adhesive bond failure, loose, curling and cracking
VCT, warped woodfloors, and damp and mold
infested carpets.
Where does the moisture vapor in floors come from?
Water is present in the ground everywhere, in
liquid form as ground water or attached to or
between soil particles and in form of water vapor
between the soil particles. While slabs on grade
are unlikely to come in contact with liquid ground
water, they definitely will come into contact with
the water vapor that rises through the soil. If a
below slab vapor retarder is missing or defective,
soil
water vapor will be able to penetrate the bottom
of the slab and accumulate in the slab if it cannot
evaporate. Slabs on grade in contact with moist
soil can also lead to capillary moisture transfer
into the slab. Basement floor slabs may come
into contact with liquid water if submerged in
ground water.
Wc+Lrr vusput
There are many sources of water
that can lead to damage of concrete floors.
Water is an essential ingredient in concrete.
At the time concrete is made, it contains liquid
water. While a part of that water is used in the
hydration of cement, another part of it remains
in the concrete and slowly evaporates over time.
The more water that is added into concrete at the
time it is batched and during curing, the longer
it is going to take to dry to a condition that is
acceptable for a flooring system.
Air conditioning and heating systems
de -humidify the air in buildings. Since vapor will
move from an area of high humidity to an area
of lower humidity, a stream of water vaporfrom
the floor slab into the air is set in motion. This
process creates a moisture gradient within the
slab; lack of a functional vapor retarder below
the slab allows moisture to continually re -charge
the slab.
Additional sources of water can be broken pipes
under a slab, spills onto concrete, building use
such as kitchens and bathrooms, cleaning and
maintenance, rain and snow, ambient relative
humidity, and condensate forming on the
concrete.
What other factors influence floor moisture vapor?
torgiv
Va
so
r'R+
rr
M'r
Missing or damaged vapor retarders
underneath slabs on ground prevent
drying offloor slabs.
Fast track construction often requires
flooring applicators to install flooring
systems before the concrete has had
sufficient time to dry.
Elevated slabs are frequently made with1110 ;,_ light weight aggregate concrete in order
to be able to build slimmer structures.
When light weight concrete is made,
the porous light weight aggregate is
saturated with water before it is added to
the mix. The water that is captured in the
aggregate of the concrete causes the light
weight concrete to need longer dry to
an acceptable level than normal weight
concrete.

buildings:
Renovation offlooring systems: In thepast,
manyflooring systems were more resistant
to moisture and high pH. Flooring systems
often have a limited breathability and
the adhesives have limits regarding the
moisture and pH they can withstand. After
a new, low permeable flooring system is
installed, moisture vapor is trapped inside
the concrete. That sets the condition for
the moisture vapor damage mechanism to
start eventually leading to failure of the
adhesive and theflooring.
Changing environmental conditions:
Moisture vapor conditions underneath a
floor slab on ground can change over time,
for example changing seasons, irrigation, or
heavy rainfalls over a long time period can
increase the soil moisture vapor condition.

concrete
Concrete is a porous material. It allows moisture
vapor to pass through it.
As long as moisture vaporcan simply pass though
the concrete, there will be a moisture gradient
with the concrete drier near the top surface and
more damp at the bottom.
Moisture can transport salts of various types into
and through the concrete causing efflorescence
on the surface of the concrete. This can be
detrimental to serviceability.
When a flooring system is installed, it typically
has lower vapor permeability than concrete.
The water vapor can no longer evaporate from
the surface of the concrete. As a result, the
amount of water vapor that is present in the slab
will slowly increase. This can be measured as an
increase in the relative humidity in the concrete
slab.
Many types of floor finishes can be damaged
when exposed to high moisture over a longer
period of time.
If concrete contains aggregate that is susceptible to Alkali Silica Reaction (ASR), the increased moisture
now present in concrete can cause the reaction to start, leading to damage of the concrete.
Microbial growth can develop underfloor coverings leading to health hazards for building occupants.
Coatings and adhesives can debond when the moisture condition underneath the low permeable
flooring becomes high enough.

concrete
Cured concrete contains soluble calcium,
potassium and sodium hydroxides. Once
dissolved in water, conditions develop with pH
readings up to 74.
Adhesives that bond floor coverings to the
concrete can degrade and fail as a result of the
high pH and moisture present on the concrete.
The high pH that develops at the surface of the
concrete due to moisture can also discolorfloor
coverings.
Once high pH condensation has developed
underneath the surface of adhered low
permeablefloorcovering, the adhesive is directly
exposed to the high pH conditions. Adhesive
can then degrade due to the high pH and high
moisture exposure.
The time frame in which this distress takes place
depends on vapor drive and the composition of
the concrete. The liquid in blisters can have a pH
of 14.
Typical for this damage mechanism is that it
usually takes 3 to 6 months for adhesives to
deteriorate.
How can moisture vapor problems be controlled?
If test results indicate an elevated moisture vapor
condition in the concrete, something needs to
be done to be able to install the desired floor
covering without producing a failure. Even if the
concrete slab is not exposed to a constant source
of moisture, drying of the slab may take many
months oryears. Usuallythat is not an acceptable

alternative. In most cases the installation of a
moisture control system is the only solution. The
moisture control system blocks rising moisture
vapor, and prevents adhesive and flooring from
coming in contact with the high pH that develops
in the concrete.
Moisture Vapor Control Systems
Successfully introduced to the flooring market
in 2007, K65TER VAP 12000 systems have an
impressive track record over more than 10 years
with thousands of satisfied customers. K65TER
VAP 1 2000 systems have been developed for
the sole purpose of protecting flooring systems
against moisture vapor damage. KOSTER VAP 1
2000 materials have been specially designed to
provide successful long-term solutions even in
dificult scenarios:
KOSTER VAP 12000 systems withstand a permanently elevated
moisture condition up to 700% RH
K65TER VAP 12000 systems resist a sustained exposure to pH 74.
KOSTER VAP 12000 systems provide a high degree of user friendliness due
to their ease of installation and one coat application.
Choosing the right moisture control system
No two flooring projects are the same, and
each has unique technical challenges.
K65TER, the specialist in the
field of moisture vapor control systems, has
developed reliable systems that protect flooring
from damage. These unique formulations are
100% solid epoxy, contain no fillers and are one
coat systems. The materials can be applied to
green concrete after 7 days, allowing for the fast
tracking offlooring projects. KOSTER VAP 12000
systems have been formulated to withstand
100%relative humidity (RH) (ASTM F2170) and up
to pH 14.
KOSTER VAP 1 products have an outstanding
vapor diffusion resistance. While all of
KOSTER's VAP I products have always been
low VOC and low odor, KOSTER now has 2
vapor suppression products that are zero VOC:
KOSTER VAP 1 2000 and KOSTER
VAP 1 2000 FS. The test certificates that show
LEED compliance are available upon request.
The available systems dffer from each other
mainly with regard to the curing times:
KOSTER VAP 1 2000 (12 hours), KOSTER VAP 1
2000 FS (fast setting 4-5 hours), for overnight
installations, KOSTER VAP 1 2000 UFS (ultm-

Why is the vapor diffusion resistance of a
moisture control system important?
Moisture vapor transmission rates are measured the factor by which a material is more resistant
by standardized test methods. The vapor dffusion against water vapor then air with the same
resistance is expressed as "p-value': The p-value is thickness.
A moisture control system has to reduce the amount of moisture
vapor to the level that the finish floor covering can tolerate.
adhesive
p= 26.000
N=150

concrete10 ay
Typical dry concrete has a vapor diffusion
resistance of p = 100. For a 70 cm slab this equals
an equivalent air layer thickness of 70 m. Many
floor coverings have a much higher diffusion
resistance to water vapor. Among floor coverings,
rubber flooring stands out because of its very
high diffusion resistance. Several manufacturers
of rubberflooring state that their products have
a vapor diffusion resistance of opprox. N = 26.000.
For a 7 mm floor covering this equals an equivalent
air layer thickness of 21,1 m.
As an example, let us consider the following
flooring system: Rubber flooring bonded with
an adhesive directly to a slab on grade made
of concrete. The concrete slab - which has a
dffuslon resistance of p = 100 - allows much
more water vapor to pass through than the
rubberflooring does - which has a p = 26.000.Of
the 700 %of water vapor that passes through the
70 cm concrete slab over a certain period of time,
less than half can pass through the 1 mm thick
rubberflooring over that same time period. The
remainder of the moisture vapor accumulates
under the adhesive and the rubberfloor covering.
The high levels of moisture and the high pH that
develop degrade the adhesive and lead to afloor
failure.

cone!
To prevent this damage mechanism, a moisture
control system has to be installed directly onto
the concrete before the flooring is installed.
This moisture control system has to bond to the
concrete despite moisture and high pH. It also
has to reduce the amount of moisture vapor that
passes through it to a level that the flooring and
adhesive can tolerate.
The KOSTER VAP 12000 moisture control system
can do all of this. It withstands the moisture
and high pH that develops underneath it and, if
installed at 400g/m2, it delivers a vapor diffusion
resistance which is considerably higher than that
of the rubberflooring used in the example. The
amount of moisture vapor which the moisture
control system allows to pass through it is lower
than the amount of moisture vapor that the
rubberflooring allows to pass through.
Flooring manufacturers publish the maximum
acceptable moisture levels for their products
in their technical literature. In order to protect
a flooring system, a vapor control system must
reduce the amount of moisture vapor that it lets
pass to meet the given requirements.
is the concrete slab dry enough to receive flooring?
28 days is often cited as the minimum length of
time for concrete to "cure"and develop strength.
This time period of 28 days is often incorrectly
interpreted as the time necessaryfor the concrete
to dry sufficiently to receive a flooring system.
As a rule of thumb: If Type 1 cement was used,
the drying time for a concrete slab in a climate
controlled environment is approx. one month per
2.S cm thickness. Fora standard 70-75 cm slab the
drying time would consequently be approx. 4 — 6
months.
Several factors can extend the drying time. To
accuratelydetermine afloor's moisture condition,
the flooring manufacturer's guidelines and the
industry standard ASTM F710 should be adhered
to, which state: 'All concrete slabs shall be tested
for moisture regardless of age orgrade level':
There are several tests that can be used to
quanta how much moisture is in a floor slab.
The relative humidity (RH) test is currently the
most widely accepted test and has become the
industry standard while the calcium chloride
moisture vapor emission rate (CaCI) test is
being phased out. Relative humidity data is not
comparable to calcium chloride test results.
The RH probe test according to ASTM F 2170 is
conducted as follows:
For slabs on ground a hole with a depth of
40% of the slab's thickness is drilled. Probes
are placed in the borehole and the results
are read after an equilibration time of at
least 71 hours. The relative humidity test
determines relative humidity in the slab.
Three tests should be carried out for the
first 100 mr with 1 per additional 100 m'.
The test results according to ASTM F2770
should not exceed the RH specified by the
flooring manufacturer. For links to current
floor covering and adhesive RH limits, see
www.RHspec.com.

Easy to understandfor project participants (easy to usefor non -trained personnel)
Moisture profile of concrete possible, when measuring at different depths
RH tests reveal moisture conditions deeper in the concrete
RH probes can quickly re -measure slab moisture conditions
Moisture testing should be carried out by
independent and certified experts. Proper
testing requires background knowledge and
experience, so that all project participants can be
assured of the quality and objectivity of the test
results. This is important, as elevated moisture
levels in the concrete can cause delays in the
construction schedule or require additional,
often not budgeted expenses. Therefore moisture
vapor problems should be anticipated during
the planning phase and hence be part of the
specifications. Flooring contractors should be
especially aware of this topic and, if a moisture
control system is not specified, talk about this
topic as soon as possible with owners and
planners - in everyone's interest.
Concrete testing: What else to look for?
When dealing with new concrete, sufficient
reliable information is usually available. In new
construction, usually the concrete mix design is
available as well as information about curing
compounds used.
When dealing with older concrete, reliable
The mix design can be reviewed and
evaluated for problematic ingredients that
can cause bonding problems for topically
applied vapor suppression products.
Topically applied curing compounds can act
as bond breakers.
Adequatedrying time forthe concrete should
be built into the construction schedule
and moisture testing should be carried out
before anyflooring is installed.
and comprehensive information is usually not
available. Substances that have a negative effect
on the bonding of the flooring system may have
been introduced to the concrete over time. If such
substances are present in the concrete that is to
be coated they can be evaluated by analyzing a
sample of the concrete.
Chemical Analysis is used to determine
if contaminants such as Sodium and/
or Potassium rich metasilicate residues
and byproducts (commonly applied as
curing compounds, surface densifiers, and
hardeners), sulfate -rich surface precipitates,
and excess chloride salts are present in the
concrete.
Thin Section Petrography Analysis is
routinely used to find out if ASR or other
deleterious constituents may be present in
concrete.
Infrared Spectroscopy and GC -MS are
used to identify and to determine IF
there are organic contaminants (e.g.
oils, grease, etc.) in the concrete, that
can interfere with bonding of the
moisture control coating.

Core testing
Core testing means that a piece of concrete is
removed from the top of the slab approx. 50 cm
in diameter and 50 cm in depth and sent to a
suitable laboratoryfor analysis. The core should be
removed dry, meaning no water should be used
in the drilling process to cool the diamond drill.

staff can recommend the right system for
the specific projects. KOSTER holds frequent seminars
on moisture vapor control systems for
all interested professionals: applicators, engineers,

Application of KOSTER VAP 12000 Systems
Testing of the substrate
moisture testing / core samples):
KO5TER recommends testing to determine
the moisture vapor condition in the concrete.
Moisture testing utilizing RH probes in situ
tests (ASTM F- 2170) is considered the industry
standard. Calcium chloride tests (ASTM F-1869)
have been used for this purpose in the past but
these are being used less.
Substrate preparation:
Concrete substrates to receive KOSTER VAP 1
2000 systems must be structurally sound,
solid, absorptive and meet acceptable industry
standards as defined in ACI Committee 201
Report "Guide to Durable Concrete" Surfaces
must be free of adhesives, coatings, curing
compounds, concrete sealers, efflorescence, dust,
grease, oils, and othermaterials orcontaminants
that may act as a bond breaker. The concrete
surface must be at least 3 °C above the dew
point' temperature. Avoid application in a
low dew point atmosphere, when the ambient
relative humidity is above 95% or the concrete
surface is wet.
Shot blast the substrate to an ICRI Concrete
Surface Profile (CSP) 3 to 4. 3 Grinding is
permitted only in areas inaccessible to shot
blasting orforedging purposes. Upon completion
of the shot blasting and grinding, the concrete
slab must be vacuumed free of all dust, dirt and

covered with primer and underlayment at later
ages as long as the coating surface is clean. KOSTER
VAP 12000 coatings must not be exposed to
direct sunlight for more than 48 hours after application
on concrete . If installing MMA's or
PMMA's, the maximum recoat window is 48 hours
after KOSTER VAP 1 2000 systems have cured.
KOSTER
VAP 12000 systems may only be applied by
KOSTER trained and approved installers.
Components of a standard flooring system
K65TER VAP 1 06 Primer for cementitious
underlayments
Installers" biggestconcerns with nonporoussubstrate
primers are usually time and money.
That is one of the major reasons why
KOSTER developed the KOSTER VAP 106
Primer Thisptoductisaonecomponent
primer, specifically designed to bond
daSYER to cementitious products, providing
E-,—,c maximum adhesion between non
porous substrate such as KOSTER VAP
12000 and the cementitious leveling
compound.
K65TER VAP 1 06 Primer is a water
based, solvent free system for
priming K65TER VAP 12000 moisture
mitigation systems, terrazzo, marble, metal decking,
ceramic, and quarry tile prior to the installation
of cementitious products such as underlayments
or separation screeds. The combination of quality,
ready to use packaging, and the rapid drying time
K65TER SL Premium - cementitious underlayment
KOSTER SL Premium is a high quality, fast
setting, fiber reinforced, low shrinking
underlayment. It provides a smooth, level
surface ready to receive flooring systems.
KOSTER SL Premium accepts all major
floor coverings and is compatible with
N most adhesives. It is resistant to abrasion
and wear. If the underlayment is installed
onto smooth, non absorbent substrates

System for concrete slabs that are contaminated with
water soluble silicates
K65TER Isolation Barrier Underlayment
Silicates are widely used as curing compounds,
in floor polishing, as denstfiers, as concrete
additives. When water soluble silicates are
present in concrete at a certain concentration,
they need to be removed mechanically, (e.g. by
grinding or shot blasting). Often, even that is
not sufficient. In such cases
v COMER . the isolating underlayment
4 KOSTER Self -Levelling IB
must be installed before
the flooring system can be
ill applied. KOSTER Self -Levelling

excessive, time consuming,
and messy concrete removal.

KOSTER Setf-Levelling IB is applied directly to the
shot blasted concrete. It creates an isolation
barrier between the substrate and the moisture
vapor reduction system. KOSTER Self -Levelling
IB is permanently tolerant to moisture and high
pH, and provides a barrier against contaminants
such as unreacted water soluble silicates. The
product has self -levelling properties which make
it easy to apply. KOSTER UAP 12000 systems are
applied on top of the cured isolation barrier after
preparing the surface by shotblasting.
Treating moving cracks and expansion joints
K65TER Joint Sealant Fs-H
Moving cracks and expansion joints must befilled
with a material that can follow the substrate
movements elastically. A joint waterproofing
must allow for movement
in the construction without
causing damage to the
construction itself. Moving
joints up to a width of 35
min can be waterproofed
with KOSTER Joint Sealant
FS-H, which is a self -leveling,
rubbery -elastic sealing
compound with high chemical resistance.
Therefore, it is an ideal material to waterproof

horizontal joints in heavy construction,
foundations, waste water treatment plants,
garages, tunnels, etc.
The expansion joint must be installed so that the
joint runs through the entire flooring system,
including all final floor coatings such as e.g.
KOSTER LF-VL. The prepared joint flanks are
coated with KOSTER VAP 1 2000. Allow KOSTER
VAP 12000 to cure for a minimum of 4-72 hours
depending on the product) before installing the
backing rod and the joint sealant. Do not use the
primer if the Joint Sealant is installed directly
onto the vapor control system.

Treating non-moving cracks and voids
Non-moving cracks and voids should be KOSTER VAP 12000
completely cleaned and repaired using KOSTER KOSTER VAP 1 2000 mixed
VAP 1 2000 mixed with KOSTER with a thickening agent concr
ndarcn e Thickening Agent.
nq Chase with a thin diamond blade or
angle grinder, do not widen or deepen
more than necessary. Cracks on
existing concrete slabs that may be
w I contaminated should be cut out 10 x
A J 10 mm to remove the contaminants
s _ from the side walls.
First, the prepared crack is primed with
KOSTER VAP 12000 Systems
KOSTER VAP 12000 (brush application). Then the
crack is filled using a mix of KOSTER VAP 12000
and K05TER Thickening Agent.
Equipment for proper installation
For the application of KOSTER VAP
1 2000 moisture control systems
a notched squeegee is used.
Squeegee kits provide everything
needed to spread resins in order to
ensure a uniform application of the
material onto the substrate.
A typical squeegee kit should
include:
2 Handles
2 Squeegees width approx. 60 cm
2 Replacement blades
2 Chia brushes 75 cm
Squeegee Frame and
Squeegee Blades
To meet the applicators
needs and the required layer
thickness, proper tools are
needed. It is important that
suitable squeegee frames,
width approx. 60 cm) and
notched squeegee blades
are used, providing a layer
thickness of 0.4 mm.
