SikaCeram®-503 TG
SikaCeram®-503 TG is 1-component, polymer - latex modified and water resistant cementitious tile grout for joints up to 6 mm. It is particularly used in conjunction with SikaCeram® tile adhesives. Suitable for use in hot and tropical climatic conditions.
- Easy to use, requires only the addition of water
- Long open time (enough time to clean residues from the tiles after application)
- Hardens without cracking or shrinkage
- Water-repellent and impermeable to many liquids
- Good abrasion resistance
- Very good adhesion to unglazed surfaces
- Available in various colours
- Mould and fungicide inhibiting
- UV resistant

Consumption
The consumption of SikaCeram®-503 TG is dependent upon the depth and width of the tile joint being grouted. In general one 20 kg bag will yield 14.4 litres of fresh mortar.
MIXING
- Pour the recommended amount of water into a suitable, clean mixing container. Stir slowly, whilst slowly adding the SikaCeram®-503 TG powder to the water and then mix thoroughly using a low speed (<500 rpm.) drill mixer until the material is fully homogeneous and lump free.
- After mixing, leave the product to stand and 'mature' for a few minutes, then briefly stir again prior to application. The finished mix has very creamy consistency, is uniformly coloured and it is easy to apply and spread.
- For areas requiring only small quantities, these can be mixed by hand, however please measure the water: powder ratio carefully, as even small differences in the mix ratio between batches can result in colour shade variations.
- Premature exposure to water or excess water in the mix can result in white efflorescence on the grout surface.
- In case of high-performances demanding applications, such as heavy-traffic floors, replacement of mixing water with SikaLatex® or SikaBond® DV is suggestible. Please contact Sika Technical Department for more information.
- Important notes: Do not add or allow any additional water to be added into the SikaCeram®-503 TG during or after mixing. Also prevent water contact with the freshly applied material during cleaning operations, or from excess atmospheric humidity and condensation or residual moisture in the substrate etc.. It is equally important to avoid wide temperature fluctuations during application and curing, as well as excessive draughts or forced ventilation. This is because excess water, temperature variations and excess ventilation, plus application on very porous tiles or substrates leading to rapid water absorption etc. can all result in colour shade differences.
APPLICATION
- SikaCeram®-503 TG is applied using a rubber blade or trowel using cross-hatch techniques, taking care to ensure the joints are filled uniformly across the whole width and along their full length.
- Using the same blade/trowel in a vertical position, remove the excess from the surface of the tiles.
- When the material starts to set, it is possible to begin the initial cleaning step, using a damp sponge. The remaining grout traces on the tile surfaces can easily be removed the next day by wiping with a clean, soft dry cloth. When SikaLatex® or SikaBond® DV has been used instead of water in the mix, this additional step should be done immediately after the initial cleaning with a damp sponge.
- Avoid application in direct sunlight and/or in excessive draughts or strong winds.
CLEANING OF EQUIPMENT
Clean all tools and application equipment with clean water immediately after use. Hardened/cured material can only be mechanically removed.
