Consumption

Tile adhesive

Consumption is dependent on the substrate, surface profile, roughness, size of the tiles, the joints between them and application technique. (single spreading/floating method or double spreading/buttering method).

As a guide for a single adhesive layer:

Size of tiles	Notched trowel size	Consumption
Small	6 mm	~2 kg/m²
Medium	8 mm	~2.5 kg/m²
Large	10 mm	~3 kg/m²

These figures are theoretical and do not allow for any additional material due to surface porosity, surface profile, variations in level or wastage etc.

Tile grout

The consumption is dependent on the size of the tiles, joint width and depth.

As a guide, consumption is indicated in following table and is expressed in g/m²

Tile Size	Joint width
Centimetres	1 mm	5 mm	10 mm	15 mm
Glass mosaic	519
5 × 5 × 0.4	264	1180	2078	2 776
10 × 10 × 0.6	201	948	1770	2 487
15 × 15 × 0.9	202	971	1853	2 655
20 × 20 × 0.9	152	737	1422	2 060
30 × 30 × 1	113	553	1079	1 580
30 × 60 × 1	85	417	818	1 204
50 × 50 × 1	68	335	660	976
60 × 120 × 1.1	47	231	459	681

These figures are theoretical and do not allow for any additional material due to surface porosity, surface profile, variations in level or wastage etc.

Consumption can also be calculated using the following formula:

S × [ (a+b+l)/(a+l)(b+l) ] × l × h × d × 10 000

S = Whole surface (m²)

a, b = Tile size (cm)

l = Joint size (cm)

h = Tile thickness (cm)

d = Fresh mortar density (kg/l)

Application steps

EQUIPMENT

Mixing

Electric single paddle mixer (< 500 rpm) with spiral paddle

Application

Notched trowel
Trowel
Rubber blade
Sponge
Soft cloth
Grout finishing tool

MIXING

SikaCeram® StarGrout is a reactive product. It sets from a chemical reaction between the 2 parts, A and B. It is therefore essential these parts are thoroughly mixed at the correct mixing ratio.

Prior to mixing all parts, mix Part A (resin) briefly using an electric single paddle mixer with a spiral paddle. Mix liquid and all the coloured pigment until a uniform colour has been achieved.

Add part B (hardener) to part A and mix parts A+B continuously until a uniformly coloured smooth consistency mix has been achieved. Mix full units only.

For a glitter effect finish to the tile grout, add the glitter particles to the fully mixed paste and mix until completely dispersed.

APPLICATION

Tile Adhesive

SikaCeram® StarGrout is applied using a suitable notched trowel.

Apply sufficient adhesive to the prepared fixing surface with the appropriate trowel / comb to the required bed thickness. Apply sufficient product to ensure adequate ‘wetting’ of the backs of the tiles.

Tiling must to be carried out on freshly applied adhesive, exerting adequate pressure to ensure 100% complete and uniform contact with the adhesive to achieve optimum adhesion.

If a skin forms on the surface of the adhesive, immediately remove the adhesive layer with the trowel, discard material and apply a fresh layer of SikaCeram® StarGrout adhesive.

Adjust tiles if required.

Clean off surplus adhesive from tile face and between tile joints before the adhesive has dried.

After the required waiting time apply the appropriate grout into the tile joints.

SikaCeram® StarGrout is suitable for laying absorbent and non-absorbent tiles indoors without any size or support limits.

On cementitious substrates, SikaCeram® StarGrout can be used for laying non-absorbent tiles outdoors up to 10 000 cm² (e.g. 60 × 120 cm). On non-heated floors and indoor applications up to 7000 cm² (e.g. 80 × 80 cm). For facade application, mechanical clamps are recommended.

For tiles > 900 cm² (e.g. 30 x 30 cm), the double-spreading (buttering) technique is always recommended.

Tile Grout

Check adhesive has fully set before grouting.

SikaCeram® StarGrout is applied using an appropriate rubber blade.

Completely fill and compact the joints uniformly.

Using the same spreader/ float, remove excess grout from the tile surfaces moving the tool diagonally across the joints.

After grouting, use a damp sponge or sponge float to clean the tile surfaces. Clean sponge regularly with clean water. For tiles with a textured surface, use a soft wet cloth to emulsify the grout while cleaning.

For final cleaning use a new sponge with clean water.

General information

Protect from adverse weather conditions, such as extremely high or low (freezing) temperatures, rain, direct exposure to sun, for at least 12–24 hours from application.
