CHARACTERISTICSINTRASIT
® RZ1 55HSP is a quick-setting waterproof special mortar featuring advanced HSP (high-solids process) technology providing decisive advantages compared to conventional mortar systems.
- Capillary inactive due to its tight matrix providing a stable micropore structure
- Extremely low shrinkage, thus even thick layers can be applied without any cracks
- Improved resistance to chemicals and salt
- Extremely short setting time even at low temperatures
- Self-crystallization provides high adhesive tensile strength on dry and damp mineral substrates
- Consistency can be varied by amount of water added – from slurry-like to naturally stable and spreadable
INGREDIENTSStandard cements, mineral aggregates, waterproofing agents, fiber fillers, HS pozzolana
USEINTRASIT
® RZ1 55HSP is used for promoting adhesion and for sealing and leveling mineral substrates with 3 mm to 50 mm thick layers.
For the subsenquently sealing and renovation of salt and humidity damaged undergrounds at the positive and negative sides.
Areas of application:
- Part of the Quick & Easy repair system for permanent repair of damaged building structures
- For making waterproof adhesive coves
- For scratch coating on masonry and concrete
- As a quick-setting filling mortar (stop and lean-mixed mortar)
- As back-dampening protection and intermediate sealing against moisture acting on the back according to DIN 18533 in the area of the basement exterior sealing made of PMBC and FPD.
PREPARATION OF THE SURFACEThe substrate must be clean, firm and sound. Remove any loose debris and dirt.
Remove brittle joint mortar.
Subsequently prime the entire area well with INTRASIT
® Aquarol 10A applied with a wide wall brush or brush.
APPLICATION | 1. | Gradually pour INTRASIT® RZ1 55HSP into clean water, using a drilling machine with mixing tool to stir the mixture well for about 1 minute. The processing consistency is attained during mixing. Observe the recommended amount of water.
Recommended mixing ratio for troweling:
25 kg INTRASIT® RZ1 55HSP : 4.5 l water.
Recommended mixing ratio for troweling:
25 kg INTRASIT® RZ1 55HSP : 5 l water. |
| 2. | After the primer has begun to dry, apply INTRASIT® RZ1 55HSP as thickly as required for leveling. |
| 3. | For optimum adhesion it is recommended to apply INTRASIT® RZ1 55HSP as a slurry in the first session.
Subsequently, the mortar can be applied wet on wet as thickly as necessary with a trowel or smoothing tool. |
| 4. | To improve adhesion to the following coating, the plaster may be horizontally roughened with a wide wall brush.
Alternatively, a scratch coat made of INTRASIT® RZ1 55HSP can be applied after a drying time of approx. 45 minutes (with a 70 % cover). |
| 5. | After about 1 hour, INTRASIT® RZ2 55HSP climate plaster can be applied as thickly as required. |
| 6. | Clean tools with water immediately after use. |
IMPORTANT NOTES- Observe a working temperature of at least +5 °C.
- Protect the fresh plaster/rendering from drying out too quickly and from unfavorable weather. Avoid draft.
- Strong temperature and/or humidity fluctuations during the full hardening/drying of the render system can lead to shrinkage cracks.
- Low temperatures will slow down and high temperatures will accelerate the setting process.
SAFETY PROVISIONS/RECOMMENDATIONSContains cement and will cause alkaline reactions when it comes into contact with moisture or water.
Please see the safety data sheet for more information regarding transport safety, storage and handling.
DISPOSALThe local waste removal regulations must be observed.
