PCI Gisogrund Primer 20 liters

PCI Gisogrund Primer and Sealing Primer for Walls and Floors

Product features

• Solvent-free according to TRGS 610 Giscode D 1
• Very low emissions GEVEMICODE EC 1
• EU 200442IIAg5030
• Improves the strength and load-bearing capacity of substrates and increases the adhesion of tiles, plasters, and wallpapers
• Secure adhesion PCI Tile adhesive adheres reliably to the primed surfaces
• Protects cement screeds or leveling compounds or smoothing compounds from rapid water withdrawal on absorbent substrates, extending the open time of the adhesive, improving adhesion, and preventing the formation of shrinkage cracks
• Prevents blistering and rapid water withdrawal during substrate leveling, e.g., with PCI Periplan or PCI Periplan Fein
• Control color blue allows good surface control
• Protects calcium sulfate anhydrite screeds from ettringite formation
• Facilitates later removal of wallpapers during renovation work
• Complies with the guidelines of the Federal Association of Gypsum Board and Gypsum Industry
• EMICODE EC 1

Colors: blue

Application areas

• For interior and exterior use
• For walls and floors
• Priming before applying liquid screeds, e.g., base leveling compounds such as PCI Periplan or PCI Periplan Extra, as well as stable base leveling compounds and other hydraulically setting mortars and anhydrite screeds
• Priming porous concrete and brickwork walls before applying gypsum and lime gypsum plasters
• Priming absorbent substrates to prevent rapid water withdrawal of subsequent materials
• Priming anhydrite screeds and construction panels
• Priming cast asphalt screeds before applying PCI tile adhesives
• Consolidating powdery absorbent screed surfaces and plasters indoors before laying tiles and mosaics
• Moisture-retardant consolidation and priming of gypsum plasters, gypsum boards, fiber gypsum boards, porous concrete, concrete, asphalt, plasters, and masonry as a pre-treatment before tiling and wallpapering

Substrate preparation

The substrate must be solid, clean, and load-bearing. Remove surfaces that reduce adhesion, such as waterproof adhesive residues, cement slurry layers, and contaminants, thoroughly. Freshly installed cement screeds must not exceed 4% residual moisture content, measured with a CM device. Sanded anhydrite or gypsum screeds must not exceed 0.5% residual moisture.

Application

Priming and consolidating gypsum substrates, anhydrite, cast asphalt, and stone wood screeds, as well as old adhesive residues, are not suitable for water-soluble adhesives, e.g., sulfate leaching adhesives.

Shake PCI Gisogrund thoroughly before use, especially in stand-up pouches. Apply evenly and thoroughly to the substrate using a roller, brush, broom, or spatula without diluting. Avoid formation of puddles. Check consolidation and drying by a scratch test. Only after drying, apply tile adhesive, wallpaper, paint, plaster, or leveling compounds such as PCI Periplan or PCI Periplan Fein.

For priming and consolidating porous mineral substrates, e.g., concrete, cement screeds, lime-cement plasters, porous concrete, lime sand bricks, etc., shake PCI Gisogrund thoroughly and dilute with water in a ratio of 1:1. Mix thoroughly. Apply evenly and thoroughly with a roller, brush, broom, or spatula. For highly absorbent substrates, a second application with PCI Gisogrund diluted 1:1 with water is recommended to achieve better consolidation and prevent blistering during leveling. Apply the second coat only after the first has dried.

After drying, check adhesion by a scratch test. Proceed with tiling, wallpapering, painting, plastering, or applying PCI Periplan or PCI Periplan Fein for leveling.
