AQURON® 2000 CURE & SEAL MOISTURE PROTECTION
1.
GENERAL
This section relates to AQURON® 2000™ to form an internal hydrogel within the
concrete to provide concrete waterproofing, prevent moisture movement in concrete and
provide CURE & SEAL, harden surface, minimize slab curl, anti - dusting, minimizes
hairline/map cracking, increases thermal resistance, allows early application / installation
of floor coverings, paint, coatings, or other impervious surfaces without additional
protection. Reduces laitance, damage from salts, chemicals, freezing and carbonation.
Provides steel reinforcement protection. Guaranteed moisture control for new concrete to
be covered with floor coverings or coatings

2.1
AQURON® CURE AND SEAL CONCRETE PROTECTION FOR CONCRETE
AQURON® 2000™ catalytic agent in a waterborne proprietary silicate base complies to
moisture retention requirements of ASTM C309, a deep penetrating, non toxic
waterborne solution which forms an insoluble calcium silicate gel within the concrete
matrix. Tested to have nil crystalline silica. Also acts as flooring preparation treatment to
eliminate drying delay beneath floor coverings.
3.
EXECUTION
Conditions
3.1
TECHNIQUE DISCUSSION
Before application, arrange a meeting to confirm the method of preparation and surface
treatment. Refer to AQURON® 2000™ Flooring Protection Treatment leaflet for Simple 5
Rules and 8 Precautions, this outlines key issues for flooring installers with detailed
flooring installation information for AQURON® 2000™ treated surfaces.
Application - new concrete
3.2
AQURON® CURE AND SEAL CONCRETE PROTECTION FOR NEW CONCRETE
Apply AQURON® 2000™ to fresh concrete as soon as the surface is firm enough to walk
on. Apply AQURON® 2000™ at a rate of 4.5 m²/litre or at a rate to satisfy the
absorbency of the concrete.
Application - aged concrete
3.3
Not Applicable to this specification.
3.5
PREPARING FOR FLOOR COVERINGS AFTER AQURON® 2000™ APPLICATION
Refer to AQURON® 2000™ Flooring Protection Treatment leaflet for Simple 5 Rules and
8 Precautions, this outlines key issues for flooring installers with detailed flooring
installation information for AQURON® 2000™ treated surfaces.
3.6
REMOVE CONTAMINANTS
Where oils or contaminants are purged to, or lay on the concrete surface, any such
contaminants must be removed from the surface while still soluble or alternatively as they
become dried. Determine on site the method of removing contaminants to use a
progress sander with vacuum, grinding, shot blasting, scraping.
3.7
TIMING AND SURFACE ABSORBENCY
Floor coverings or coatings should not be installed to AQURON® 2000™ treated
concrete substrates earlier than 28 days from the date of the concrete pour or within 72
hours after the application of AQURON® 2000™
Check the total floor area to ensure surface is absorbent and voids have not been filled or
glassed over by AQURON® 2000™. Where this occurs abrade the surface before
installing floor preparation, adhesives or coatings.
To ensure satisfactory adhesive grip and bonding as a part of general floor preparation,
scrape, stone or progress sand concrete floors before the application of further
preparations and floor coverings.

3.8
RELATIVE HUMIDITY LEVEL
Relative humidity levels "before and after" AQURON® 2000™ treatment will read the
same or higher as AQURON® 2000™ "locks up" the moisture.
3.9
CONTAMINATION OR GLAZING
Should any contamination or glazing be visible on the surface, test this with water. If this
produces greasiness, this must be removed to ensure a moisture absorbing non-greasy
surface.
3.10
CONDENSATION
If condensation occurs do not install floor coverings until the ambient temperature of the
area rises to allow absorption of the condensation into the general atmosphere. The
concrete surface temperature must be greater than 7 to 8°C.
3.11
HARD POLISHED CONCRETE
Grind/abrade any hard polished surface substrate before the installation of preparations,
floorings or coatings.
3.12
ADHESIVES
Where adhesives are applied over AQURON® 2000™ treated concrete allow sufficient
tack off time as the greater percentage of moisture within the adhesives, needs to be
released into the atmosphere.
Completion
3.13
LEAVE TO REQUIRED STANDARD FOR FOLLOWING PROCEDURES
Leave adjacent materials, fittings and finishes clean and to the standard required by
following procedures.
3.14
REMOVE RUBBISH
Remove debris, unused materials and elements from carrying out this part of the work
from the site.
