The maximum wet layer thickness must not exceed 4 mm!
The stated values represent typical product characteristics and are not to be construed as binding product specifications.
Field of application
- Waterproofing in new buildings
- Can be applied > 3 m in the ground
- Connection to water-impermeable concrete structures
- Cross-sectional waterproofing in and under walls
- Wall base and render waterproofing
- Subsequent exterior waterproofing in existing buildings
- Bonding layer on old bitumen coatings
- Can be applied directly from the container without mixing
- Fast, crosslinker-assisted complete drying
- Can be activated extremely quickly if required for a rainproof surface in seconds
- Rapid bond adhesion, even on non-mineral substrates
- Very low emissions (GEV-EMICODE EC 1Plus)
- Radon-tight (verified through testing)
- Highly flexible, elastic and crack-bridging
- Water pressure tight
- Can be plastered and painted over
- Can be applied as a slurry, with a brush or trowel, or by spraying
The substrate must be clean, dry, flat and capable of bearing a load, and free of dust, oil, grease and release agents.
Roughen non-mineral substrates.
Remove projecting seams and mortar remains.
Break off or chamfer corners and edges.
Produce the sealing cove with a suitable mortar.
Seal off indentations > 5 mm using a suitable filling knife.
Roughen the surface of plastic pipes with sandpaper; clean and, if necessary, sand metal pipes.
If necessary, provide damp proofing.
Prime absorbent mineral substrates with Kiesol MB.
Create a scratch coat using the product as a contact layer and in order to prevent blisters.
Vertical/horizontal surface waterproofing, and waterproofing in and under walls:
Apply the product in two layers on the previously prepared substrate.
Pipes passing through walls
W1-E: seal passing-through pipes by using the product to form a cove around them.
If render is to be subsequently applied, an additional layer of grout should be spread on to the last layer of waterproofing. SP Prep can then be thrown over the entire surface of the fresh layer of grout.
Composite and reinforcing mortar can be applied over the top without an additional slurry layer/preparatory mortar.
Direct coating with binder-rich dispersion coats.
Always set up a trial area/trial areas first.
During application, the surface temperature of the substrate must be > 3 kelvin above the dew point temperature of the surrounding air.
In the case of liquid-applied waterproofing materials, direct sunlight and/or wind exposure can cause accelerated skin formation and accompanying blistering.
Do not use in direct sunlight.
The scratch layer does not as a rule count as a waterproofing layer.
Protect the fresh waterproofing layer from rain, direct sunlight, frost and condensation water.
Once dry, protect from mechanical damage.
If there is a risk of rain, spray MB 1K ADD rapid onto the waterproofing.
Add a further load-distributing layer if using the product for waterproofing under raised floor supports.
Ensure sufficient ventilation when applying the product in closed areas (wear respiratory protection if necessary).
Please contact Remmers Technical Service (phone +49 5432 83900) before applying with machine processing.
Working tools / cleaning
Scoop, smoothing trowel, layer thickness trowel, slurry brush, flat brush, roller
Clean tools with water while the material is still fresh.
Any material that has already begun to dry can only be removed mechanically.
Storage / shelf life
If stored unopened in its original container in a cool, dry place and protected against frost, the product will keep for at least 9 months.
Min. 1.3 kg/m²/mm dry layer thickness
Layer thickness and application rate when using as crack-bridging MWS for interiors and exteriors: see application rate table under Application Examples
Apply to a large enough trial area to determine the precise amount required.

This accounts for application-related fluctuations dv as well as the additional material needed to level out the substrate du. If the substrate is levelled separately (e.g. with a scratch coat), du is eliminated from the calculation.du = scratch coat, application rate approx. 0.5 kg/m² (depending on the substrate)dv = not required with layer thickness trowel/without layer thickness trowel: application rate approx. 0.4 kg/m² (dmin = 3 mm)The maximum wet layer thickness must not exceed 4 mm, otherwise there is a risk of cracking!
The characteristic data of the product were calculated under laboratory conditions at 20°C and 65% relative humidity.
The material is UV-resistant on vertical surfaces in the wall base area and can also be used without a coat of paint/plaster applied in areas without ground contact.
A change in colour is possible, but has no impact on the waterproofing function.
Deviations from applicable regulations must be agreed separately.
The guideline “Planning and Execution of Waterproofing Building Elements with Ground Contact using Flexible Waterproofing Slurries”, published by Deutsche Bauchemie, 1st edition as per July 2020, should be observed.
The relevant test certificates must be observed when planning and carrying out work.
The special agreements as well as test certificates can be downloaded online at www.remmers.com.
Always set up a trial area/trial areas first.
Larger quantities of leftover product should be disposed of in the original containers in accordance with the applicable regulations. Completely empty, clean containers should be recycled. Do not dispose of together with household waste. Do not allow to enter the sewage system. Do not empty into drains.
