is a waterproof, flexible, protective coating used under ceramic coverings in showers and bathrooms. This one component, solvent-free synthetic resin is perfect solution to for light complex waterproofing in your wetroom. Recommended usage on substrates sensitive to moisture and the absorbent mineral surfaces. Dedicated for applying indoors - for e.g. bathroom or kitchen walls and floors.
PCI Lastogum, compared to competitive products, characterized with very fast drying and incredible leak tightness. Second layer can be applied just after one hour, tilling possible after a further 2 hours. Product is avaiable in two colours: grey and white, for easier visual control of the layer thickness. Dry layer thickness is approx. 0.7mm, which works perfect in places where we want to avoid increasing the height.
PCI Lastogum 4kg Grey is a perfect choice in case sealing only connections and gaps between floor/wall and wetroom. 4kg container will cover approx. 3.5 m² (Consumption: approx. 1.1 to 1.2 kg/m²).

Application of undiluted PCI Lastogum to the substrate by roller, brush or trowel.
The substrate must be structurally sound, dry (cement screed 4%, anhydrite flowable screed 0.5%, measured with CM meter), clean and free from oil, grease and other residues which should be removed by sand-blasting, brushing or shotblasting (Blastrac) if necessary. The practically smooth surface must be free from honeycombs, gaping cracks or ridges. Prime gypsum-based substrates and plasterboards beforehand with undiluted PCI Gisogrund. Prime absorbent mineral substrates with PCI Gisogrund, diluted 1 : 1 with water. Prime dry, tightened particle boards with PCI Wadian. The primers must have cured before applying PCI Lastogum.
