MD LIQUID BLOCK  is a versatile universal sealant that can be used in various areas such as roofs, walls and wet rooms. In the automotive sector, it serves as a supplement to underbody protection and as a paintable seam sealant. It provides waterproofing for skylights, skylight domes, roof eaves, pipe joints, wall and chimney connections and external ventilation. It can also be used to seal balconies and terraces under tiles and coverings and to seal cracks and fractures in brickwork.

Processing:

The surfaces must be firm, sound and free of contaminant matter (dust, oil, dirt etc.). Remove all residues of previous coatings thoroughly.
MD LIQIUD BLOCK has excellent adhesion to many construction materials such as concrete, glass, plaster, ceramics, tiles, wood, and various metals such as aluminium, steel, zinc and copper. Does not discolour metals, even those that are not painted. Bitumen can cause discolouration. Please always carry out preliminary tests!
MD LIQIUD BLOCK can also be used without primer on damp surfaces, however, not in standing water.
MD LIQIUD BLOCK can be used directly from the container, only stirring is required prior to application. It can be applied with a roller or brush/wide paint brush to a thickness of 2 coats of 1 mm. After drying, a layer thickness of about 2 mm should have been achieved. Apply the second layer after the first layer if completely dry (about 3 hours at 23 ° C and 50% relative humidity). After 12 hours (at 23 ° C and 50% relative humidity) the treated area is completely dry and downstream activities can be resumed. Temperature variations and / or changes in humidity can cause delayed curing. Use approx. 1.4 to 2.0 kg/m2. 

Notes:

• Connection and expansion joints must be properly prepared in order to achieve optimal results. Professionals backfill material is unavoidable here (for example, for extrusion foamed polyethylene).
• For optimum elasticity of the sealant over the joints go to 2: 1 or max. 1: 1 width / depth ratio of the joint (minimum joint width 6 mm, maximum 20 mm).
