MB 2K

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.

In coves, embed Tape VF series into the material and smooth to < 20 mm.

Optionally, use a suitable mortar to produce a sealing cove.

Close indentations > 5 mm with a suitable filler or with MB 2K mixed with suitable quartz sand (MR of between 1:1 and 1:3).

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.

Apply a scratch coat (approx. 500 g of MB 2K/m²) with the product itself as a contact layer and in order to prevent blisters.

Mix the liquid component (component A) with a suitable mixing tool.

Pour the loosened powder component (component B) completely onto the liquid component.

Mix for approx. 1 minute before suspending the mixing process to allow the air that has been stirred in to escape.

Remove the powder adhering to the side.

Mix again for approx. 2 minutes.

Keep the mixing tool near the bottom of the bucket while mixing.

Temperature of the material, air and substrate: from min. +5 °C to max. +30 °C.

Vertical surface waterproofing

Apply the product in two layers on the previously prepared substrate.

Horizontal surface waterproofing

Apply the product in two layers on the previously prepared substrate.

After the waterproofing has dried thoroughly, place two layers of PE sheet over the waterproofing before the screed is laid.

At the edges, the waterproofing layer is applied up to the upper edge of the floor or up to the horizontal barrier.

Horizontal waterproofing in and underneath walls

Apply the product in two layers on the previously prepared substrate.

Connection details/building element joints

Use the joint tape system to bridge corner and connecting joints, as well as connections to rising components (e.g. full-length windows, doors).

Apply the product, apply Tape VF over the entire surface and embed so that it is crease-free.

Pipes passing through walls

W1-E: seal passing-through pipes by using the product to form a cove around them.

W2.1-E: use a suitable loose/fixed flange to integrate pipe lead-throughs in the waterproofing material. Alternative: use Remmers pipe flange.

Use Remmers Pipe Flange in cases where the water load is "pressing water".

Plinth render

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.

Work can be continued with compound mortar and reinforcement mortar after approx. 4 hours without an additional layer of grout/preparatory mortar.

Follow-up work and coverings

After 4 hours, work can be continued with adhesive mortar, filling
mortar or reinforcement mortar.

Coating

Direct coating with binder-rich dispersion coats.

Always set up a trial area/trial areas first.

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.

Do not use on untreated aluminium.

The scratch layer does not as a rule count as a waterproofing layer.

The maximum total wet coat thickness must not exceed 5 mm.

Moving the material (e.g. by stirring) in the mixing bucket can prevent premature skin formation.

Mortar that has already set cannot be made workable again by adding
water or fresh mortar.

Protect the fresh waterproofing layer from rain, direct sunlight, frost and condensation water.

Once dry, protect from mechanical damage.

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.

Mixer, ladle, smoothing trowel, layer thickness trowel, wide brush, surface 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.

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.

At least 1.1 kg/m²/mm of dry coat thickness

Coat thicknesses and application rate when used as a crack-bridging MWG in interior and exterior areas: see application rate table under application examples.

Apply to a large enough trial area to determine the precise amount required.

The characteristic data of the product were calculated under laboratory conditions at 20°C and 65% relative humidity.

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.
