PRODUCT USE BASF The purpose of this work is the moisture treatment of facades supported on thin plastering mortar and precast concrete panel flashing and sealing cover. Surface preparation in grooved precast concrete panels Manufacturing defects are repaired: voids and bumps on site with repair mortar Emaco R-205, once repaired apply 2 coats of Masterseal 326. Consumption approx 350 kg of Masterseal 326. Surface preparation mortar facade: Masterseal hand 317 50% diluted in water, due to the porosity of the support and the diluted product is applied to ensure adhesion of subsequent layers of Masterseal 317, in this case 3 coats were applied prior profiling perimeter seal applies a flashing mode. Consumption approx. 1,300 kg of Masterseal 317 Other applications: Are also supplied 300 kg of Masterflow 952 for anchoring machinery. Also Emaco S-88 is supplied as structural repair mortar. Masterflex 474 48 sausages 600 ml is spent. Installation company: IMPERMITEC, SL established in Ponferrada (León)
