underfloor heating. It is single-part, permanently flexible and isocyanate-
free

SURFACE PREPARATION:
- Subfloors must be dry, sound, smooth, clean, and by the relevant
Floorcoverings Australian Standards 1884 - Subfloors must also be free of wax, grease, oil, polishes, old adhesive,
curing compounds, high levels of moisture (> 90% RH) and any other surface
contaminants that may affect adhesion. - If mechanical preparation is required, prepare the floor using
recommended methods such as shot blasting, scarifying, and diamond grinding to
provide a roughened, clean, sound, solid and open porous surface. - The minimum subfloor temperature before commencing installation should
be 10°C. Do not use solvents or acid etching to clean the subfloor.
STANDARD ADHESIVE:
- All concrete subfloors must be tested for moisture content.
- Relative humidity readings should be determined as per ASTM F2170.
- Ensure the relative humidity (RH) is below 85% (tested as per ASTM F2170
in-situ probe method). - If the RH of the sub-floor is above 85%, we recommend the use of RLA
MOISTURE SEAL.
3 IN 1 ADHESIVE< VAPOUR BARRIER AND MEMBRANE SYSTEM:
- This product can be used as a vapour barrier for up to 90% RH on
concrete substrates. - If the RH of the sub-floor is above 90% RH, we recommend using RLA
MOISTURE SEAL. - The minimum subfloor temperature before commencing surface preparation
and adhesive application is 10°C. - Please refer to the application instructions below.
- The manufacturer’s recommendations should treat indentations and uneven
concrete subfloors with the RLA range of levelling compounds. - Contact our technical staff for advice when temperatures less than 10⁰C
or greater than 30⁰C are encountered.
MOISTURE PROTECTION:
- Concrete slabs can be a source of excess moisture.
- To prevent moisture migration, apply Two coats of RLA MOISTURE SEAL
ensuring the second coat is applied perpendicular to the first coat’s direction. - Applying Timber Flooring Adhesive onto RLA Moisture or Vapour Barrier,
ensure the adhesive is applied onto the Moisture Barrier within four days after the
Moisture Barrier application has taken place and cured. - Ensure the Barrier is clean and free from dirt, dust and any other
contaminant that may affect adhesion. - Concrete slabs can be a source of excess moisture.
CONCRETE SUBSTRATES:
- Subfloors must be dry, sound, smooth, and clean, and any contaminants
that may affect adhesion and by the relevant Floorcoverings Australian Standards. - All concrete subfloors must be tested for moisture content before
applying the adhesive, primers, and barriers. - The manufacturer’s recommendations should treat indentations and uneven
concrete subfloors with the RLA range of levelling compounds.
TIMBER SUBSTRATES:
- Timber flooring must be solid, sound, clean and free from wax, oil, free
from gaps and securely fixed and in accordance with the Timber Flooring
Manufacturer’s Instructions and relevant Australian Standards. - Timber Flooring and Particle Board may be coated with a resin waterproof
protective layer. - This layer can act as a bond breaker and affect adhesion of applied
finishes.
- It should be removed by sanding the subfloor before applying timber
flooring. - It is recommended to install timber flooring onto timber substrates
- Timber Flooring is nailed/ secretly fixed in combination with the
application of adhesive. - Please ensure adequate crossflow ventilation and the minimum height
clearance between the earth and the timber flooring is by the relevant Australian
Standards. - Failure to have sufficient ventilation can result in moisture build-up
under the subfloor and compromise the installation of underlayment and floor
coverings.
VAPOUR BARRIER AND MEMBRANE SYSTEM:
- When applying this adhesive onto concrete substrates up to 90% RH as a
vapour barrier, ensure RLA X3 adhesive is applied with a 5mm x 5mm V5 notched trowel
and 100% transfer of the adhesive film is achieved. - If the RH of the sub-floor is above 90%, we recommend using RLA Two Part
Epoxy Moisture Barrier.
VAPOUR BARRIER PERFORMANCE:
- For the adhesive to function correctly for Vapour Barrier performance,
the trowelled adhesive must be flattened when the timber is pressed into the
adhesive to ensure a homogenous adhesive film forms a barrier between the
subfloor and the timber floor covering. - 100% transfer contact between the substrate and timber flooring must be
achieved. - Apply adhesive evenly with a 5mm x 5mm V5 notched trowel.
- Note: Always refer to the timber manufacturer’s instructions for
specific trowel size as a larger notched maybe required.
NOISE REDUCER ACOUSTIC PERFORMANCE:
- When 100% transfer of the adhesive film is achieved, RLA X3 Timber
Flooring Adhesive provides a noise-reducer barrier over substrates. - Apply adhesive evenly with a 5mm x 5mm V5 notched trowel.
- Note: Always refer to the timber manufacturer’s instructions for
specific trowel size as a larger notched maybe required. - The trowelled adhesive must be flattened when the timber is pressed into
the adhesive to ensure a homogenous adhesive film forms a barrier between the
subfloor and the timber floor covering. - 100% transfer contact between the substrate and timber flooring must be
required
APPLICATION:
- PLEASE REFER TO TECHNICAL DATA SHEET – ATTACHED
CURE TIMES:
- Cure times can vary substantially and depend on weather conditions such
as temperature and humidity. - Typically, SMP will form a firm skin in one hour and cure in
approximately 24 hours. - Hotter and more humid conditions will increase the cure rate and
decrease the skin time, whereas colder climates and lower humidity will
reduce cure times and increase skin time.
COVERAGE:
- 2 to 3mm V-notched trowel will achieve coverage of approximately 2
square metres per litre. - A 4 to 5mm V-notched trowel will achieve coverage of 1 to 1.2 square
metres per litre.
PACKAGING:
- 10 Litre / 15 kg Containers
SHELF LIFE/STORAGE:
- 12 months when stored in original unopened packaging.
- To be stored in a cool dry and weatherproof environment off the ground.
PRECAUTIONS:
- Always ensure the flooring is placed into the wet film of adhesive and
apply sufficient pressure to ensure transfer occurs between the adhesive film and
the floor covering. - DO NOT allow the adhesive to skin, and DO NOT place timber flooring onto
the skinned glue. - A minimum of 90% (Transfer) contact between the substrate and the back
of each piece of timber is required. - Maintain complete contact with the adhesive until full cure is achieved
after a minimum of 24 hours (mechanical fixing or weighing down is recommended). - Vapour barrier and noise reducer performance by applying the adhesive evenly with a 5mm to 6mm V-notched trowel and ensuring the timber flooring is
placed into the wet adhesive film. - Application of timber flooring adhesive directly onto RLA MOISTURE SEAL.
Ensure the adhesive is applied onto the Moisture Barrier within four days after the
application of the Moisture Barrier has taken place and cured. - Do not walk on laid matting during the first four hours after
installation. - Avoid air entrapment when making the bond or filling joints.
- For application details of timber flooring systems, contact the
manufacturer. - Care should be taken to prevent any reaction or damage to pre-finished
timber coatings. - Do not use adhesive in excessively hot or cold conditions, i.e., below
10°C or above 28°C. - This adhesive will not stand up to hydrostatic pressure or capillary
action. - Ensure your trowel is consistently notched to the manufacturer’s
recommendations. - Timber flooring systems must be acclimatised; refer to the timber
flooring manufacturers’ recommendations before using this adhesive. - If in doubt regarding the suitability of the adhesive, always contact
the manufacturer. - Always follow the manufacturer’s instructions
- Do not apply over acrylic or PVA primers/sealers.
- Not recommended to be used in totally confined spaces as it requires
atmospheric moisture to cure properly. - Do not expose to water or alcohol-based cleaners before the complete
cure. - Adhesive must be fully cured before sanding; allow a minimum of 72
hours. - Compatibility tests must be first carried out.
- Due to the many forms of timber flooring available today, the installer
should undertake preliminary adhesion testing to confirm adhesion. - RLA Technical can assist with large projects.
- Do not apply over dense burnished concrete surfaces without abrading
first to obtain a mechanical key for the adhesive to bond.
