GROUT KNAUF FUGENBUNT BERMUDA BLUE 2 KG

Knauf Fugenbunt is a cement-based, ready-to-mix joint filler for indoor and outdoor use. It is suitable for filling joints 2–8 mm wide in all types of wall and floor tiles (including natural stone and concrete tiles). The unfilled joint must be at least 2 mm wide. If the substrate is unstable or subject to temperature fluctuations, it is recommended to add the Knauf Fugen-Elast plasticizer. Color: Bermuda blue. Instructions for use: Pour the Knauf Fugenbunt dry mix into a mixing bowl with clean water, mix into a paste, and let stand for 2–3 minutes, then mix thoroughly again. Stir again before use, apply to the joints with a rubber trowel, and let set for 10–15 minutes (the surface will become matte). Then smooth the joints with a damp sponge wrung out well and remove any excess mixture from the tiles. Rinse the sponge occasionally. Wipe the surface carefully so as not to wash the grout out of the joints (the grout should extend to the edges of the tiles). To ensure the grout sets properly, it’s a good idea to spray the setting grout with water several times during the first 2–3 hours after finishing the job, especially in warm and dry rooms. Once the joints have dried, clean the tile surface with a soft cloth. Note: If the joints need to be flexible (e.g., for underfloor heating), add Knauf Fugen-Elast plasticizer to the grout (1 liter per 5 kg of mixture).
