Parex Aquatic Mortar accelerated

Anti-washout rapid setting mortar  

Parex Aquatic Mortar accelerated is blend of special Portland cements, high quality graded sands, and unique combinations of polymers and admixtures. The product contains no iron, high alumina cement, chloride or deleterious substances. Parex Aquatic Mortar accelerated is used when ambient temperatures are low, or when an early strength gain is required.
The product is easily mixed with gauging water to produce a putty-like consistency for ease of application. The mixed material will not disperse, wash out or break up in water or underwater situations. The placed mortar develops rapid early strength even at low temperatures. The anti-washout properties enable effective plugging and sealing of leaks in running water situations.

  • Easy to use - just add water.
  • Very rapid setting.
  • Anti-washout properties.
  • Suitable for application to Brick, Masonry and Concrete.
  • High early strength gain.
  • Consistency - good workable mortar.
  • Chloride free.
  • Suitable for plugging and sealing leaks in riunning water.
  • Non-shrink.
  • Suitable for use in relatively low temperatures. 
  • EuroClass A1 reaction to fire.

Application steps

SURFACE PREPARATION

Ensure all contact surfaces are clean, free of contamination and marine growth. In underwater locations, for cleaning, use a water jet. For surfaces situated in the tidal zone, or above the waterline, use hot compressed propane burning to remove contaminants, abrade the substrate and clean the surface.

MIXING

Add the required quantity of water to a suitable mixing vessel. Slowly add the powder to the water whilst continuously mixing. Suitable mixers include a slow speed high torque (1kW) drill with a Mortar Stirrer. After all the powder has been added mix for a further 1 to 2 minutes. Mixing by hand is NOT recommended. 
 

APPLICATION

Use a gloved hand to form a contact / scratch coat. Work and compact the mortar onto, and well into, any cracks or cavities and completely cover the substrate. The contact / scratch coat will reduce voids at the bondline and promote intimate contact between the repair material and the concrete. It will also prevent peeling and slumping on vertical and soffit substrates.

On top of the contact / scratch coat, use a trowel or steel float to apply the mixed mortar and build up to the profile of the surrounding concrete. For ease of working and application of the mortar above the waterline, keep gloves and all implements wet. Use a handheld water sprayer to wet mortar surfaces and to produce a smooth finish.

CURING TREATMENT

Protect the fresh mortar immediately from premature drying for a minimum of 3 days using an appropriate curing method (e.g. curing compound, wet hessian, moist geotextile membrane, polythene sheet, etc.). 
Curing compounds shall not be used when they adversely affect subsequently applied products and systems.. 

CLEANING OF TOOLS

Clean all tools and application equipment with water immediately after use.
Hardened / cured material can only be mechanically removed.
