RLA Moisture Seal

DESCRIPTION:

RLA MOISTURE SEAL is a high-performance, 2-part water based epoxy primer and barrier coating system designed to prevent moisture and vapour ingress and rising damp through surfaces

FEATURES & BENEFITS:

• Water based, solvent free and low VOC
• Withstands up to 25 metres or up to 250Kpa of hydrostatic pressure
• Can be applied to damp and “green” concrete
• Extended pot life
• Outstanding adhesion properties
• Fully compatible with RLA waterproof membranes, coatings, adhesives and leveling compounds
• Complies with AS 4020 for potable water storage

USES:

• General primer and adhesion enhancer for overlaid RLA waterproof membrane systems
• Barrier coating system over surfaces containing residual moisture or subject to rising damp to protect overlaid RLA waterproof and epoxy coating systems against blistering or delamination
• As a barrier coating system to protect overlaid decorative floor & wall finishes including paints, vinyl, carpet, tiles, timber flooring and levelling compounds against damage caused by residual moisture, moisture vapour, rising damp & efflorescence
• Moisture barrier to negative sides of underground wall structures to prevent moisture ingress and seepage (basements, lift pits, retaining walls etc)
• Waterproof coating for potable water storage applications
• High strength, high performance waterproof repair mortars

SUBSTRATES:

• Concrete & concrete block
• GRC – glass reinforced concrete
• Screed and render
• Masonry
• Timber
• Compressed fibre cement sheeting including James Hardie Scyon™Secura™

NOTE: For suitability over any substrate or material types not listed above, contact RLA Technical Department for confirmation of suitability and surface preparation

APPLICATION & COVERAGE

• Over floor surfaces product can be applied using a squeegee, stiff nylon broom or medium/long nap roller.
• Over vertical wall surfaces a medium-long nap roller is recommended
• Work the Moisture Seal into surfaces to enable optimum absorption and penetration into the substrate and to ensure all pinholes and voids are filled.
• Where multiple coats are required, apply subsequent coats at right angles to the previous coat
• RLA recommends regular testing of the depth of the coat with a wet film thickness gauge at regular intervals during installation.
• Check dry film for pinholes and recoat as required

GENERAL PRIMER AND ADHESION ENHANCER

Uses:

• General primer and adhesion enhancer for overlaid RLA waterproof membrane systems to approved substrates including James Hardie Scyon™ Secura™ compressed fibre cement sheeting
• Apply 1 x coat @ coverage of 1litre/10m² forming a 100 micron wet film thickness and a 50micron dry film thickness

Waterproofing Applications

Uses:

• For application over damp or “green” substrates with elevated residual moisture readings >80% RH when tested to ASTM F2170, or 5% moisture content when tested to ASTM F2659 and with the moisture content falling*
• Apply 1 x coat @ coverage of 1litre/5m² forming a 200 micron wet film thickness and a 100micron dry film thickness.

Flooring Applications Uses:

• For application over damp or “green” substrates with elevated residual moisture readings ≥90% when tested to ASTM F2170, and with the moisture content falling* –
• Apply 1 x coat @ coverage of 1litre/5m² forming a 200 micron wet film thickness and a 100micron dry film thickness.
• For substrates with readings > 95% RH when tested to ASTM F2170, and/or where the moisture content is not falling and hydrostatic pressure or Alkaline is present
• Apply 2 x coats @ coverage of 1litre/5m² forming a 200 micron wet film thickness and a 100micron dry film thickness.

*Always refer to individual product TDS for application recommendations and moisture tolerances

MOISTURE BARRIER COATING:

Uses

• Hydrostatic barrier coating to floor and wall surfaces against permanent / continuous moisture and rising damp
• Efflorescence prevention through floor & wall surfaces
• Waterproof coating to potable water storage vessels and immersed applications
• Apply 2 x coats @ coverage of 1litre/5m² per coat forming a total minimum dry film thickness of 200 microns

HIGH STRENGTH REPAIR MORTARS

Uses:

• Patching surface defects and irregularities
• Crack and general repairs
• Waterproof fillets Moisture Seal Repair Mortar 1 part mixed Moisture Seal 1 part Portland cement 3 parts fine wash sand

Method:

Combine wet and dry components and mix thoroughly to form a working mortar consistency and apply with spatula or trowel

Note: Only mix what can be used for the application as product cannot be stored
