Cement-based putty for joints with a width of 4 to 20 mm (0.787 in)

SikaCeram® LargeGrout is a one-component, cement-based grout for filling joints with a width of 4 to 20 mm (0.787 in) in ceramic tiles. The additive content gives active protection against mold, bacteria or fungi that could stain or damage the putty. The new pigmentation system gives vivid shades, stable over time. SikaCeram® LargeGrout can be used for grouting porcelain tiles, vitrified tiles or marble, obtaining water-resistant joints, which offers the possibility of using the product in applications such as tanks, swimming pools, etc.

Consumption

The consumption depends on the dimensions of the tiles and the width of the joints between them.

An indicative consumption guide, expressed in g/m2, considering the thickness of the plates of 10 mm (0.394 in).

Consumption can also be calculated with the formula: S x [ ( a + b + l )/( a + l )( b + l ) ] x l x h x d x 8300

S = Total surface (m2) a, b = Board dimensions (cm) l = Joint width (cm)h = Plate thickness (cm) d = Density of fresh mortar (Kg/l)
shuffle
  • Pour the recommended amount of water into the pre-cleaned cooking pot. Gradually add the powder to the water, mixing simultaneously with a mixer at low speed (< 500 rpm), until a homogeneous paste, free of lumps, is obtained.
  • Allow the paste to mature for a few minutes and re-mix briefly before application. The paste thus obtained has a creamy consistency, is evenly pigmented and is easy to apply.
  • If a small amount of putty is required, it can be prepared by hand. Pay attention to weighing the amount of water, small differences in the amount of preparation water between two applications can cause variations in the color of the putty.
  • In the case of applications with special performance requirements or subject to intense demands, such as public floors, facades, swimming pools, or for additional flexibility, the preparation water will be replaced with SikaCeram® LatexGrout, the tiles used in these cases being especially non-porous tiles.
  • Premature exposure to water or humidity or the use of excess preparation water leads to the appearance of efflorescence on the putty surface.

Notes: Do not add additional water during or after homogenizing SikaCeram® LargeGrout. Avoid contact of the freshly applied paste with water, except when washing the putty. Also avoid exposure to high atmospheric humidity, condensation or residual moisture of the substrate. Avoid exposure to significant temperature variations during application and during the setting time of the putty, very dry environment or forced ventilation. Excess water, temperature variations and excess ventilation, application on very porous tiles or on highly absorbent substrates can lead to variations in the color of the putty.

APPLICATION
  • SikaCeram® LargeGrout is applied with a spatula or rubber trowel, diagonally to the direction of the joints, until they are completely filled.
  • Using the same spatula/trowel held in a vertical position, remove the excess grout from the surface of the tiles.
  • After starting the material, the washing process can be started, using a moistened sponge. The putty traces left on the ceramic tiles can be easily removed the next day with a soft, dry cloth. If SikaCeram® LatexGrout was used to prepare the grout, wipe the tiles immediately after washing with the sponge.
  • Avoid commissioning in a very dry environment, in strong sun or wind.
CLEANING OF TOOLS

Tools and surfaces soiled with unhardened adhesive should be cleaned with water, preferably immediately after application. Hardened material can only be removed mechanically.
