Isocrete Aqualock
Surface Damp Proof Membrane

DESCRIPTION
Aqualock
A two coat solvent and water free epoxy resin liquid
applied surface damp proof membrane designed to
withstand moisture pressure from substrates of up to
100% Relative Humidity.

Aqualock One Coat 
A single coat solvent and water free, epoxy resin, liquid applied surface damp proof membrane designed to withstand moisture pressure from 
substrates of up to 90% Relative Humidity.

Aqualock Plus 
A two coat solvent and water free, epoxy resin, liquid applied surface damp proof membrane. Finished with Isocrete 1500 to provide a surface 
ready to directly receive floor finishes.

Fast cure grades of the above are available if required for very fast track refurbishment projects. 

Can be used in combination with Aqualock Adhesive (see separate datasheet) for the rapid installation of rubber flooring on 
damp concrete bases.
       

USES
Aqua lock
Allows immediate installation of moisture sensitive floor finishes onto concrete and cementitious screeds which have o moisture content of up to 
100% Relative Humidity.

Aqualock One Coat
Allows immediate installation of moisture sensitive floor finishes onto concrete   and cementitious screeds which have a moisture content of up to
90% Relative Humidity.

Aqualock Plus
Allows immediate installation of moisture sensitive floor finishes onto concrete   and screeds which have a moisture content of up to 1 00% Relative 
Humidity. The Isocrete1500 leveling screed is suitable to receive mostfloor finishes, such as vinyl, carpet, rubber, tiles, timber and similar.
       

BENEFITS
• Reduces project timescale. Allows early installation of floor finishes.
• Impervious to water.
• Excellent adhesion to concretes and screeds.
• Tolerates up to 100% Relative Humidity in the
   concrete or screed substrate.
• Easy to apply.
• Solvent free, low odour.
• Excellent gap filling properties.
• Contrasting colour coats allows for visual control of the Aqualock membrane uniformity in laying. 
• The Aqualock System can be used for either, heavy duty industrial or medium to light duty commercial applications.
• With Aqualock Plus, Isocrete 1500 high strength (30 N/mm2) leveling screed the entire floor construction is available from one supplier.

    

SURFACE PREPARATION
Either by totally enclosed shot blasting or light scarification. Edges completed by vacuum controlled hand tools. All residues must be removed 
to provide a dust free, open textured surface with exposed aggregates. The substrate should be surface dry before application of the Aqualock 
resin.

APPLICATION
Aqualock & Aqualock Plus
Apply the first coat (red) by squeegee and roller at a coverage of 0.28kg/rn2 and allow to cure to a tack free condition (7-1 5 hours, dependent
on temperature).

Within 24 hours of the first coat, apply the second coat (yellow) by squeegee and roller at a coverage of 0.22kg/rn2. Broadcast to full cover over 
the wet Aqualock with 0.2 to 0.4mm dry Silica Sand (coverage approx 2kg/rn2) and allow to cure overnight.

If a resin topping or coating is to be applied within 24 hours of the second coat of Aqualock the sand scatter may be omitted. If Isocrete 1500 is 
used to level prior to a floor finish, then Isocrete Primer should be used.

Aqualock One Coat
Apply Aqualock One Coat by squeegee and roller ensuring an even coating at a coverage rate of 0.33kg/rn2. Broadcast to full cover over the wet 
Aqualock One Coat with 0.2 to 0.4mm dry silica sand and allow to cure overnight.

Note: It is essential that the coverage of 0.33kg/rn2 is maintained and that there are no pinholes in this single coat application.
lsocrete.

Light Duty Areas
For light duty areas, the Isocrete 1500 can be applied onto the unsanded Aqualock using Isocrete Primer.

MIXING
All Systems
Pour total Hardener B into Base A container and drain thoroughly. Ensure that the materials are properly mixed using a slow speed industrial 
hand drill and helical spinner.

PROTECTION ON COMPLETION
All Systems
Protect the installed membrane from other trades prior to the floor covering application. It can be desirable to leave the excess sand on the s
urface as protection until the final covering is applied. Excess sand must be fully removed and the floor vacuumed before application of the 
underlayment.

OVERLAYING
Semi dry thick section cementitious screeds may be laid directly into the wet second coat of Aqua lock.
Prior to bonding floor coverings such as carpet and vinyl, Isocrete 1500 or a latex underlayment such as Isotex is normally applied.
For direct bonding to Aqualock, the adhesive manufacturer should be consulted to determine if a sanded or unsanded finish is required.

COLOURS
Aqualock and Aqualock Plus. Supplied in two colours, red for the first coot and yellow for the second coat.

TEMPERATURE
Aqualock should not be applied at material or floor temperatures below 10°C. Temperatures should not fall below 5°C in the 24 hours after 
application.

TOOL CLEANING
Clean with Flowsolve Cleaner before the product has cured.

HANDLING & STORAGE
Stored unopened in dry conditions at 10-25°C, shelf life will be 12 months minimum.

PACKAGING
Available in 5kg and 10kg composite packs consisting of Bose A and Hardener B. Base A supplied in red and yellow.
