5 The substrate must be sound, free from loose sections, dust and oils. Brittle or dusting surfaces must be primed first with the micromolar stabilizer AQUAFIX or the SOLVENT BASED PRIMER of DUROSTICK. Surfaces, already coated with paints and/or adhesives (such as ceilings), must first be stripped from their coating(s) and they have to be thoroughly cleaned in order to ‘receive’ smoothly dB Block. Steel surfaces are properly prepared by applying the appropriate primer. Apply the ready-to-use product as is, with a 4-6mm notched trowel to achieve a coat thickness between 2-3mm. Continue by smoothing the surface with the straight edge of the notched trowel to yield a satisfactory smooth surface. The product can also be applied with a finishing/spackling trowel, depending on the coating thickness and the application. In hard to reach areas and corners, apply the product in 1-2 coats of equal thickness, with a wide brush or an emulsion brush. Please allow for 5-7 hours to pass between coats, always depending on the ambient conditions (temperature, humidity). For better workability, dilute it up to 5% with water, depending on the application. Surface preparation Use Apply it on interior and exterior, horizontal or vertical building surfaces, such as plaster, concrete, plaster board and lightweight construction surfaces, wood surfaces, wood constructs form OSB, marine grade plywood, etc., metal surfaces and steel construction surfaces, aluminum panels, sheet metal, polyester, plastic surfaces, PVC piping and a variety of other materials. dB Block is ideal for application in new, under construction or existing buildings, plus for hotel and store renovations, catering hall renovations, etc. Applications
