Tile Adhesive SG-400 (Gray)
Cementitious ceramic tile adhesive with extended open time and reduced slip.
Fields of Application
— Floor and wall bonding of all types of ceramic tiles, mosaic and decorative bricks on cementitious renders, cementitious screeds and concrete.
— The substrates must be notched or primed with SIMENTEK BETONEX before bonding of tiles on existing ceramic tiles.
— High adhesion strength.
— Allows installation of tiles from top towards the bottom.
— Extended open time.
— Easily trowellable.
— Substrates must be sound, free from oil, grease, and sufﬁciently dry. Cementitious substrates must be cured.
— Use SIMENTEK SGP500 in case of uneven substrates to get a sound and ﬂat surface.
— Wipe the back side of tiles with water if dusty.
— Pour 25 kg of SG-400 into 6.5-8 liters of clean water slowly and mix to obtain a homogeneous paste free from lumps.
A low speed mixer is recommended to mix. Do not add any additive which is not mentioned in the instructions for the application
— Allow to stand for 5-10 minutes to mature. After 1-2 minutes remixing, the paste is ready for application.
— Spread the mortar onto the substrate with notched trowel of which notch size is appropriate to the tile dimension. To obtain a good adhesion ﬁrst apply a thin coat of SG-400 with the ﬂat side of trowel, then notch with the toothed side of trowel.
— Open time is 30 minutes. Install the tiles within this period with pressure. Unfavorable climatic conditions (high temperature, low humidity, wind, etc) can reduce this time to just a few minutes. If this period exceeds, scratch and discard the mortar.
— Dispose mortars of which pot life is expired. Clean tools and hands with water, surfaces with a damp cloth.
— Tiles installed with SG-400 must not be subject to water for at least 24 hours.
— Since contains cement, irritating to eyes, respiratory system and skin.
— Indicated consumption is a general information. It may change depending on the application conditions and surface properties.
— Store in dry medium. Do not stack more than 10 bags on top of each other.
— 25 kg multi-ply paper bags.
