PCI Seccoral 1K Sealant

PCI Seccoral 1K Flexible Sealant for Sealing Under Ceramic Coverings on Balconies, Terraces, and in Shower Areas

Product Properties

• Single component PCI Seccoral 1K is mixed on site with water
• Crack-bridging high safety for subsequent substrate cracks
• Crack-free curing; the coating does not peel or break out
• Excellent adhesion; no special primer or adhesion bridge required
• Plastic, flexible, easy to process by brushing or trowel application
• Frost-resistant, transportable
• Vapor-permeable
• Sprayable, pumpable, suitable for application with a spatula

Application Area

• For interior and exterior use
• For wall and floor applications
• Approved by building authorities for the production of bonded waterproofing in heavily water-exposed areas according to the exposure classes A and B as per the building regulations list
• For flexible sealing under tiles on balconies, terraces, and in shower areas
• For coating solid drinking water tanks or swimming pools with water depths up to 8 m
• For applications in moisture exposure classes A 0 and B 0 according to the current ZDB leaflet on bonded waterproofing and the ZDB leaflet on ceramic coverings in swimming pool construction
• Mechanically durable up to exposure class III according to the ZDB leaflet on high-stress coverings

Substrate Preparation

The substrate must be firm, largely even, and finely porous on the surface. It must be free of nests, open cracks, ridges, dust, water-repellent coatings, paint layers, or other adhesion-inhibiting layers. Pits and gravel nests on the wall should be filled with concrete filler PCI Polycret 5 or repair mortar PCI Polycret 20. Housings and concrete hollow blocks must be plastered with a plaster from mortar group CS III according to DIN 9981 before coating. Edges should be broken, with chamfers or fillets with a minimum radius of 4 cm, and rounded internal corners should be formed with construction mortar or repair mortar PCI Repafix. Cement-bound substrates must be thoroughly pre-wetted; at the time of application, they should be matt, moist, but free of water films or puddles. Gussasphalt screeds indoors and ground Anhydrite or gypsum screeds with unvibrated PCI Gisogrund or PCI Gisogrund Rapid should be primed. Allow the primer to dry. Anhydrite or gypsum screeds indoors should not have more than 0.5% residual moisture content, measured with a CM device.

Processing of PCI Seccoral 1K

For processing PCI Seccoral 1K, at least two coats are necessary depending on the application process, each to be applied fully covering. The finished coating must have the required minimum layer thickness at every point.

Mix the powder with the appropriate amount of water in a sufficiently large mixing container and stir with suitable stirring or mixing equipment attached to a drill until a lump-free mortar is obtained. Let PCI Seccoral 1K mature for about 3 minutes, then stir briefly again.

The first application, in a more fluid consistency, with a water amount of 290 ml/kg PCI Seccoral 1K powder, is applied thoroughly and evenly by brush, roller, or spatula. Carefully cover corners and broken edges. Allow the primer coat to dry.

Pipe penetrations and floor drains are sealed with PCI Pecitape 10 / 10 or PCI Pecitape 425 / 425. Seal corner joints and wall-floor connections where no internal angles have been formed with PCI Pecitape 120. Lay PCI Pecitape into the first coat and cover with the second coat.

After the first coat has dried, subsequent coats can be applied either again with a spatula or with a roller to achieve the required layer thickness.

Laying Ceramic Coverings

On the walkable PCI Seccoral 1K sealant, ceramic coverings can be laid after approximately 24 to 48 hours using PCI Nanoflott, PCI Rapidflott, PCI Nanolight, PCI Flexmörtel, or PCI Flexmörtel Schnell. In exterior areas, the coverings must be installed without cavities.
