Suitable substrates are concrete to EN 206-1 (minimum strength class C 20/25), plaster/render minimum strength class CS III to EN 998-1), masonry produced of brick or sandlime brick with joints completely filled with cement mortar. Prior to being coated, foamed slag bricks and hollow concrete blocks are to be plastered/rendered in accordance with mortar group CS III to DIN 998-1. The substrate must be structurally sound, mainly even and fine-pored in the surface. It must be free from honeycombs, gaping cracks and ridges, dust, water repellents, forming oil or other residues which could impair adhesion. Fill voids and honeycombs on walls with PCI Polycret 5 concrete filler or PCI Pericret repair mortar. Break edges and round grooves flush with a minimum radius of 4 cm. Form covings with site-mixed mortar or the repair mortar PCI Repafix. Prewet the cementitious substrate; it must be damp at the time of application, but not overwatered. Prime mastic asphalt screeds indoors and rough-ground anhydrite screeds and/or gypsum-based flowable screeds with undiluted PCI Gisogrund. Allow primer to dry. Anhydrite screeds and/or gypsum based screeds indoors must not have a residual moisture content exceeding 0.5% (measured with CM meter). Lime cement renders are to be primed with PCI Gisogrund diluted 1 : 1 with water if necessary.
It is required to apply two coats of PCI Seccoral 2K Rapid fully covering the substrate. The finished coat must have the required minimum thickness over its entire area for the expected water load (see "Technical Data/Application").
Prewet the prepared cementitious substrate. The substrate must still be damp, but not overwatered, when applying the waterproof coating PCI Seccoral 2K Rapid. No pre-wetting is required on primed mastic asphalt screed, anhydrite screed and/or gypsum-based flowable screed.
Apply the first coat using e.g. a flat bristle brush or roller until the entire surface is saturated. Make sure that corners and rounded edges are thoroughly covered.
Do not backfill the excavation pit until the coating has thoroughly cured (after approx. 3 days*), protect excavation pit by taking appropriate measures in accordance with DIN 18195. Protect coating from damages which may be caused by subsequent works, e.g. by a gypsum-free trowel plaster, protective screed, foam or mineral fibre boards, foils or other surface coatings.
