The 3 x 3 of perfect building waterproofing
MB 2K is the genius among multi-functional building waterproofing from Remmers. Over the last few years, the familiar properties of this all-rounder have been constantly improved and refined. In addition to offering unbeatable crack bridging at ultra-low coating thicknesses and extremely fast drying times, MB 2K can also be applied using all common methods.
 | Layer thickness only 3 mm up to 3 m immersion depth without reinforcement: No matter what the application, 3 mm is enough. Even when waterproofing components in contact with the ground to protect them against pressing water, an application of MB 2K with a dry layer thickness of 3 mm is sufficient – without the need for fabric reinforcement. |
 | Tested crack bridging of more than 3 mm without reinforcement: In practical terms, crack-bridging capability means safety. With crack bridging of more than 3 mm, MB 2K is more flexible than conventional waterproofing systems, meaning that even areas subjected to high stresses can be permanently and securely sealed off. |
 | Can be filled after 9 hours¹, always set after 18 hours² With MB 2K, you save time as well as material. Thanks to its unique special formulation, MB 2K dries and cross-links incredibly quickly. In a standard climate, it can be filled after just 9 hours. |

Spraying, spreading and brushing
Remmers MB 2K is a multi-functional wonder when it comes to application too. When applying the material by hand, users can opt for spreading, brushing, or even rolling.
On difficult-to-reach transitional areas and small surfaces, such as those found at wall bases and along the ground course, application by brush as a slurry is the established method. On larger surfaces, we recommend applying with a trowel. The low dripping losses and high stability of the material mean highly efficient surface coverage.

A plus in efficiency
for all areas of application
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 50 m². Thanks to the 1 : 1 pre-packaging of Remmers MB 2K, significant amounts of time can be saved on site – which
means major efficiency gains too. For smaller projects, the 3 : 3 packs are the perfect solution. For plinth waterproofing, for use in conjunction with joint tape or similar applications, this pack size prevents you from wasting valuable material.
