INTRASIT® RZ1 55HSP

Properties

• capillary inactive due to dense matrix with stable micropore structure
• extremely low shrinkage, therefore crack-free even in thick layers
• improved chemical resistance and salt resistance
• very rapid strength development, even at low temperatures
• Self-crystallisation leads to high adhesive pull values on dry and moist mineral substrates
• Consistency can be adjusted from slurryable to stable and trowelable by adding the appropriate amount of water

Applications

• Part of the instant renovation system for the permanent renovation of damaged building fabric
• for the production of waterproof and adhesive covings
• as a fast-setting filling and tamping mortar
• as rear moisture protection and intermediate waterproofing against moisture acting from the rear in accordance with DIN 18533 in the area of external basement waterproofing made of PMBC and FPD

Composition

• Standard cements
• Mineral aggregates
• Hydrophobic agents
• Fibrefillers
• HS-Puzzolane

Substrate

Properties/tests

• The substrate must be clean and sound.

Pretreatment

• Remove loose particles, dust and adhesion-depleting contaminants.
• Scrape out any joint mortar that is not sufficiently solid. Then apply INTRASIT Aquarol 10A to the entire surface with a trowel or brush and spread well into the substrate.

Processing

Processing

• Sprinkle INTRASIT RZ1 55HSP into clean water and mix intensively for approx. 1 minute using a low-speed drill and stirring basket. The working consistency is achieved during the mixing process. Observe the water quantities.
• Recommended mixing ratio
  Fillable: 25 kg INTRASIT RZ1 55HSP: 4.5 l water
  Slurryable: 25 kg INTRASIT RZ1 55HSP: 5.0 l water
• INTRASIT RZ1 55HSP is applied in the layer thickness required for levelling after the primer has been applied until matt damp.
• For optimum adhesion, INTRASIT RZ1 55HSP should be applied as a slurry in the first coat. The mortar can then be applied fresh in fresh in the required layer thickness using a spatula and trowel.
• For better adhesion for subsequent coats, comb the plaster horizontally to create a 3 – 4 mm deep toothing. Alternatively, after a waiting time of approx. 45 minutes, an adhesive spray coat of INTRASIT RZ1 55HSP can be applied. This should be applied as a mesh (approx. 70 % coverage).

Drying / Hardening

• Initial setting begins after approximately 40 minutes; final setting is complete after approximately 50 minutes (at +20 °C and 60% relative humidity)

Cleaning the tools

• Clean all tools and equipment with water immediately after use.

Notes

• Maintain a processing temperature of +5 °C to +30 °C.
• Protect the fresh plaster from drying out too quickly and from unfavorable weather conditions. Avoid draughts.
• Strong fluctuations in temperature and/or humidity during the curing/drying of the render system can lead to shrinkage cracks.
• High temperatures accelerate, low temperatures delay the setting process.
