- Based on the construction site, the quantities listed here can increase by 1 - 1.5 kg/m² (due to the uneven ground or the application of the material). Equalization and scratch coats must be considered separately.
1) At +20 °C and 60% relative atmospheric humidity.
PREPARATION OF THE SURFACEThe substrates must be firm, capable of bearing load, free of adhesion-inhibiting ingredients.
Apply IMBERAL
® Aquarol 10D as a primer on absorbent mineral substrates. Once cleaned, old and adherent bitumen coatings can be covered without further priming.
For example, the following substrates are suitable for the application of sealant:
Masonry as per DIN 1053, for example, made of:
- bricks
- hollow blocks and solid bricks/blocks made of
Lightweight concrete and concrete, granulated slag bricks
- lime-sand bricks, aerated concrete blocks
- concrete shuttering blocks, mixed brickwork
- concrete/reinforced concrete as per EN 206-1 in conjunction with DIN 1045-2
- plaster (DIN V 18550) mortar group P III, CS III, CS IV acc. to DIN EN 998-1
Existing bituminous paints and coatings on a mineral substrate, as well as on existing, old mineral sealing compounds.
- cement screed
- old fixed tiled coverings
Other substrates not listed above must be checked to ensure their suitability for each area of application. The masonry must cover the entire surface. Holes are filled with INTRASIT
® RZ1 55HSP. Coves are also formed using INTRASIT
® RZ1 55HSP.
In the case of masonry, DIN 1053 stipulates that butt joints exceeding 5 mm in width, for example for bricks not laid with the butt ends facing each other, must be sealed on the outside with mortar when the bricks are laid. Open recesses greater than 5 mm, such as mortar pockets or holes, must be filled in advance with INTRASIT
® SM 54Z/ INTRASIT
® RZ1 55HSP. Coves are likewise formed using INTRASIT
® SM 55Z/ INTRASIT
® RZ1 55HSP. Open butt joints measuring up to 5 mm and surface profiles or unevenness of blocks (for example, plaster grooves for bricks or heaving concrete blocks) must also be evened.
PREPARATION OF THE SURFACEFor masonry consisting of porous aggregate lightweight or concrete bricks, special measures are required to seal the pores (e.g. scratch coating with IMBERAL
® RSB 55Z). The scratch coat must be allowed to dry/harden for approximately 2 hours before the next work phase commences. Concrete must also be checked. Imperfections and ridges that may have been caused by the form work when the concrete was poured must be eliminated in the same way as for masonry. Separating substances such as mould oil or curing agents must be removed. When exposed to solar radiation, pores that are open or covered can lead to the formation of blisters in the freshly applied coating. To reduce the risk of blister formation, a scratch coat should be applied. The scratch coat must be allowed to dry/harden before the next work phase commences. Layers of cement paste or firmly adhering dirt must be removed mechanically (e.g. rotating discs/milling machines). The edge of the concrete floor slab must be beveled. Before applying the sealant, the prepared concrete floor slab (floor slab protrusion) must be thoroughly cleaned. Hollow plastering around the cavities must be removed and replaced accordingly. Sandy plaster must be firmed up or removed and replaced where necessary. Existing waterproofing is only suitable as a substrate for IMBERAL
® RSB 55Z if the material compatibility can be ensured. In case of doubt, material compatibility must be verified by applying a test coat/bond. Furthermore, the existing waterproofing must be checked to ensure adequate adhesion to the substrate. Loose parts must be removed. Following the application of a scratch coat, the product can be applied directly to the old substrate. Priming is not required. In general, tar coatings and tar sheets are not suitable substrates for sealants.
A coating thickness > 2 mm is required as a sealing layer for balconies and terraced areas that are subsequently covered with floor tiles resting on tile supports or with a combination of natural stone and spatula-applied coverings. We recommend embedding fabric wadding (IMBERAL
® VE 89V) into the first layer.
A minimum thickness of 2 mm is required as a sealing layer around brick contact areas.
APPLICATIONThe “Guideline for Planning and Executing Waterproofing using Flexible Waterproofing Grouts“ must be adhered to.
| 1. | Pour the IMBERAL® RSB 55Z liquid components and add the powder while mixing. Using a low-speed mixing tool (400-600 rpm), mix the components homogenously. The mixing duration is at least 2 minutes. |
| 2. | IMBERAL® RSB 55Z can be applied by brush, trowel, or by spraying. Make sure that the sealing compound is applied evenly. The viscosity of the material can be adjusted with up to 0.5 l of water. This is especially suitable for slurry coatings with a thickness of 2 - 3 mm. |
| 3. | The maximum coat thickness per work phase is 8 mm. |
| 4. | Depending on the particular application, the material application must be applied in one or two work phases. In areas subjected to particularly high stresses, a reinforcing core must also be integrated. See the “Quantity required“ section. |
| 5. | Allow a drying time of at least 2 hours between coats depending on the weathering conditions. The first layer must not be damaged by the application of the second layer. |
| 6. | Wash all processing equipment with clean water immediately after use. |
IMPORTANT NOTES- Observe the working temperature of +5 °C to +25 °C.
- If the product is applied in direct sunlight, at elevated temperatures and windy weather, early skin formation must be expected.
- Only use on dry or mat moist substrates.
- Rough trowel marks in the surface are to be avoided.
- The instructions in DIN 18533 apply in this case.
- If using HADALAN® MST 89M as a decorative lining on substrates where there is a risk of crack formation, HADALAN® DS61 13P must be used as waterproofing.
- For level sleepers, doors and window elements with increased crack width changes> RÜ3-E, we recommend the use of IMBERAL® DAB 30P.
- If there is a risk of moisture on the back, carry out back moisture protection from INTRASIT® RZ1 55HSP or INTRASIT® DS1 54Z
SAFETY PROVISIONS/RECOMMENDATIONSThe powder component produces an alkaline reaction when it comes into contact with water. For detailed information regarding safety during transport, storage and handling, refer to the updated safety data sheet.
DISPOSALThe local waste removal regulations must be observed.
