MD LIQIUD BLOCK is a universal seal for the most diverse areas, such. as roofs, walls, wet cells. For vehicles as a complement to underbody protection and as a spreadable seam sealant. The manufacture of waterproofing for roof lights, skylights, gutters, pipe junctions, wall connections, chimney connections, outdoor ventilation etc. waterproofing balconies and terraces under tiles and coverings is easily possible. Waterproofing of cracks and fractures in masonry. MD LIQIUD BLOCK suitable for substrates such as Styrofoam, plastics, concrete, wood, stone, metal, sanded roofing felts. MD LIQIUD BLOCK provides a crack-bridge of at least 10 mm, it is UV resistant and not sensitive to rain and spray water (even during curing).

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. 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).
