• For wet areas with non-pressurized water, such as bathrooms, showers in residential buildings, hotels, nursing homes, and hospitals
• For balconies and terraces
• For swimming pools
• For sealing under ceramic coverings with chemical exposure, such as in breweries, dairies, soft drink industries, slaughterhouses, cold storage rooms, paper factories, laboratories, hospitals, etc.
• On moisture-sensitive absorbent substrates, e.g., gypsum plasters, gypsum boards, fiber gypsum boards, plasterboard, wood chipboards, anhydrite screeds in humid and wet rooms with household use
• On mineral absorbent substrates, e.g., concrete, screed, cement plaster, porous concrete, cementitious wall spackling compounds such as PCI Pericret, PCI Nanocret FCR2, R3, R4, and self-leveling leveling compounds like PCI Periplan
• With general building authority approvals
• For steam cabins
• As waterproofing under parquet coverings in private bathrooms, moisture exposure class A0

Substrate Preparation

The substrate must be solid, dry, and free of dust, grease, and other residues. If necessary, remove these residues completely by sandblasting, shot blasting, or bead blasting (Blastrac). The surface should be as even as possible; if necessary, level using PCI Periplan, PCI Pericret, or PCI Nanocret FCR2, R3, R4. The surface must not contain nests, open cracks, or burrs.

Gypsum-containing substrates and gypsum boards must be primed with PCI Gisogrund undiluted. Absorbent mineral substrates, e.g., concrete, screed, cement plaster, porous concrete, cementitious wall spackling compounds such as PCI Pericret, PCI Nanocret FCR2, R3, R4, and self-leveling compounds like PCI Periplan, should be primed with PCI Gisogrund diluted 1:1 with water. Dry, firmly screwed wooden chipboards should be primed with PCI Wadian. Primers must be fully dried before applying PCI Pecilastic W.

Application

Lay out PCI Pecilastic W and cut to size with a utility knife or scissors. Apply PCI Flexmörtel or PCI Flexmörtel Schnell, PCI Nanolight, or PCI Nanoflott light, according to the technical guidelines, with a 4 mm or 6 mm notched trowel onto the prepared substrate. Within the open time of approximately 30 minutes for PCI Flexmörtel, PCI Nanolight, and PCI Nanoflott light, or about 20 minutes for PCI Flexmörtel Schnell, lay the PCI Pecilastic W membranes and press them in. Overlap the membranes by approximately 5 to 10 cm. Seal overlaps with PCI Seccoral 1K2K Rapid waterproof adhesive. Apply PCI Seccoral 1K2K Rapid in the overlap area without gaps onto the PCI Pecilastic W membrane and press the second membrane into the overlap within the open time.

Seal corner joints and floor-wall connections with PCI Pecitape 120. Attach PCI Pecitape with PCI Seccoral 1K2K Rapid onto PCI Pecilastic W and wall connections, then press in. For moderate moisture exposure, e.g., residential areas, bonding overlaps and sealing strips can also be done with PCI Lastogum or PCI Pecitape Bond.

After the curing of the thin-bed mortar (PCI Flexmörtel S1 or PCI Nanoflott light after approx. 12 hours, PCI Nanolight after approx. 5 hours, PCI Flexmörtel S1 Rapid after approx. 3 hours), the top layer can be installed.

Elastic Grouting

Movement and joint gaps in ceramic coverings are elastically sealed with PCI Silcoferm S, and in natural stone coverings with PCI Carraferm elastically.

Application of PCI Pecilastic W for Waterproofing under Parquet Coverings in Private Bathrooms with Moisture Exposure Class A0

First, seal the floor-wall joint

Apply SMP parquet adhesive PCI PAR 365 with a suitable notched trowel, e.g., A1 according to TKB, to the floor and the lower wall area (about 6 cm wide or high). Press pre-formed special inner corners PCI Pecitape 90° I or special outside corners PCI Pecitape 90° A into the fresh adhesive in the floor-wall corners. Then, press in the special sealing tape PCI Pecitape 120 into the floor-wall transition and fold it over. Subsequently, attach the flexible waterproofing membranes PCI Pecilastic W, cut to size with a utility knife or scissors, fully covering the area and overlapping the membrane edges by approximately 5 to 10 cm with PCI PAR 365 on the prepared substrate. Use an appropriate trowel notch, e.g., A1 according to TKB. Marking strips printed on the membranes serve as a guide for overlaps. After embedding the membranes into the fresh adhesive bed, press them fully with a cork board. Once the adhesive has cured sufficiently (about 1 day), a parquet approved by the manufacturer for installation in bathrooms can be glued onto the sealed surface with PCI PAR 365.
