How to apply MB 2K+


Make sure the substrate is clean, dry, and flat (remove any projecting seams and mortar). 


Stir the liquid component of MB 2K with a suitable mixing tool. Next, loosen the powder component and add all of it to the liquid component. Mix for approximately one minute and then stop to allow any air to escape the mixture. Remove any powder that’s adhered to the side of the bucket, before mixing for a further two  minutes. We recommend keeping the mixing tool near the bottom of the bucket while mixing.


How you apply MB 2K+ depends on your application and the desired results. Download the DataSheet for more application details covering vertical and horizontal waterproofing.
