Dependent on the particular substrate the following preparation measures are to be carried out: Cement-based surfaces: • Abrasion Steel surfaces: • Bright metal (Sa 21/2) Design requirements: The design requirements for joint construction must be as given in accordance with DIN 18540 as well as the IVD data sheet No.1 (Industrial Sealants Association) and verified on site. In particular the joint width must be calculated so that the total joint movement is not greater than that suitable for the joint sealant. Product preparation: INDUFLEX-MS is delivered ready-for-use in 600 ml sausages and is to be used with a suitable gun. Strike off the sealant with a suitable smoothing tool and press onto the joint edges and backfilling profile or stable backfilling material. Within the product working time smooth the joint surface if required by lightly smoothing over with a spatula or soft brush with the aid of a smoothing solution. Method of application / consumption: 1. Prepare the joint void by blocking with a suitable closed cell backing strip. In the process, ensure that the backing strip does not become damaged. 2. Prime the joint edges. Pre-treat highly absorbent mineral-based joint edges with INDU-Primer-S, nonabsorbent joint edges with INDU-Primer-N. 3. Before applying sealants, protect joint flanks from contamination with a self adhesive strip. 4. Apply the joint sealant: INDUFLEX-MS is installed with a suitable caulking gun.
The consumption of INDUFLEX-MS is calculated using the formula: joint width (mm) x filling depth of the sealant (mm) = ml/m joint. Example: Joint dimension: Joint width 20 mm and fill depth 17 mm = 1.75 m per 600 ml sausage. During the curing time exclude early stresses (e.g. very high temperature differences; vehicular traffic with direct contact). Important advice: • Higher temperatures reduce the working time. Lower temperatures lengthen the working time and setting time. • The bond between the individual materials can be heavily impeded through the influence of dampness or contamination between the two layers. • Applications that are not clearly mentioned in this technical data sheet may only be carried out after consultation and written confirmation from the Technical Services Department of SCHOMBURG. Please observe a current EU health and safety data sheet. Chemical resistance (extract): Freshwater, seawater, fertilizer, household effluent, industrial effluent, organic acids such as e.g. acetic acid.
