Remmers MB 2K (Multi Tight 2K)

3014

Remmers MB 2K (formerly Multi-Tight 2K) is a flexible, polymer thick coating which combines the properties of flexible and crack-bridging mineral waterproofing grouts (MWG) and bitumen-thick coatings (PMBC).

  • For rapid waterproofing of building elements as well as containers, tanks and reservoirs, both indoors and outdoors
  • WTA-compliant retroactive waterproofing
  • Approved for connecting to water impermeable concrete structures
  • Repair of flat roof waterproofing on roofs of structures which are not habitations
  • Horizontal waterproofing in and underneath walls
  • Tested on crack formation of greater than 3 mm (according to DIN EN 14891)

The 3 x 3 of Perfect Building Waterproofing


Safety

 

Versatility

 

Grout, Filling and Spraying

Remmers MB 2K is a multi-functional wonder when it comes to processing too.

When applying by hand, the user can opt to work with the material as a grout, or apply it using a trowel or even a roller.

On transition areas that are difficult to reach and on small surface areas, such as wall positioning areas and plinths, applying as a slurry has proven effective.

On larger surfaces, Remmers recommend applying with a trowel. Low wastage and high stability of the material ensure high surface coverage.

It is especially effective to apply Remmers MB 2K by spraying. When using machine technology suitable for the construction site, spray application is an efficient alternative to manual methods for surfaces starting from just 40 to 50m².

Thanks to the new 1 : 1 pre-packaging of Remmers MB 2K, significant amounts of time can be saved on site – which means major efficiency gains too.

Preparation


Substrate requirements

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.

 

Substrate preparation

Remove projecting seams and mortar remains.

Break off or slope corners and edges.

In coves, embed Tape VF (Art. 5071) into the material and smooth to < 20 mm.

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

Close indentations > 5 mm with a suitable filler or with MB 2K mixed with Selectmix RMS (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 mineral substrates with Kiesol MB. Kiesol MB ist not suitable for non-absorbent substrates (e.g. watertight concrete).

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.



Production of the Mixture


Combi-container

Stir the liquid component with a suitable mixing tool.

Loosen the powder component and add it in full to 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 2 minutes.

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



Directions


Conditions for use

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

Low temperatures increase, while high temperatures decrease the working and setting time.

 

Working time (+20 °C)

30-60 minutes

 

Vertical surface waterproofing

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

Horizontal surface waterproofing

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

Connection details/building element joints

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

Apply MB 2K and work in the Tape VF so that it is crease-free.

Pipes passing through walls

Seal passing-through pipes by using the product to form a cove around them.

When an adhesive flange or loose/fixed flange is used for pipes passing through walls, they should be bedded into the waterproofing.

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 covers

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.



Tips on Use


Do not use under direct sunlight.

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.

Unless a further load-distributing layer is added, the product is not suitable for waterproofing under raised floor supports.

Ensure sufficient ventilation when applying the product in closed areas (wear respiratory protection if necessary).

Please contact us before applying with machine processing.
