Sika SikaCeram-50 Tilofix
Polymer-modified cementitious adhesive (C1T / IS 15477 Type-1 ‘T’) for fixing ceramic and vitrified tiles up to 30×30 cm on interior floors and walls.
What is it?
A grey, cement-based powder adhesive modified with polymers, mixed on site with water to bond ceramic and vitrified tiles. It is classified C1T under EN 12004-2 and Type-1 ‘T’ under IS 15477-2019.
Where is it used?
Indoor floors and walls in residential settings such as kitchens, bathrooms, balconies and terraces, over cured cementitious plaster, screed and concrete substrates.
Why use it?
It gives a far stronger, more consistent bond than site-batched cement-sand mortar, is self-curing, and needs only clean water added, which removes the guesswork of thick-bed spot fixing.
How is it applied?
Mix with water using a slow-speed drill, let it mature 2-3 minutes, comb onto the prepared surface with a notched trowel at 3 mm minimum bed, and press each tile firmly for full contact before it skins over.
About Sika SikaCeram-50 Tilofix
SikaCeram-50 Tilofix is Sika India’s entry-grade thin-bed tile adhesive, engineered for the everyday tiling that makes up the bulk of Indian residential work. It is a normal-setting, self-curing blend of Portland cement, redispersible polymers and graded aggregates that arrives as a grey powder in 20 kg and 40 kg bags. On site you add only clean water, mix to a creamy consistency, and comb it onto the substrate. The result is a controlled 3 mm bed that bonds absorbent ceramic, earthenware and vitrified tiles far more reliably than the traditional cement-sand dab-and-fill method most contractors grew up with.
The product is built specifically for absorbent tiles on absorbent, cementitious backgrounds indoors. It carries a C1T classification under EN 12004-2:2017 and meets IS 15477-2019 as a Type-1 ‘T’ adhesive, with a tested tensile adhesion strength of at least 1 N/mm2 against a 0.5 N/mm2 requirement, and slip of no more than 0.3 mm. That headroom over the minimum standard is what keeps tiles from creeping on walls and gives the installed floor its durability. For Space Arc’s engineer and contractor customers, it is the practical default when the spec calls for a certified, standard-set adhesive rather than a premium flexible or highly-deformable grade.
The technical insight
The performance gain over conventional mortar comes from the polymer fraction. When the powder is gauged with water, the redispersible polymer particles film-form as the cement hydrates, leaving a flexible polymer network threaded through the rigid cement matrix. That network wets the tile back and the substrate, closing the microscopic gaps a stiff cement-sand mix leaves behind, so a far greater share of the bed is in true contact. Because coverage on the tile back should reach 100 percent, there are no hollow voids to crack or debond under load. The self-curing chemistry means the polymer retains enough mix water for the cement to hydrate on its own, so you get consistent strength development without ponding or hessian curing. The thin 3 mm bed also matters mechanically: less material means less shrinkage stress and a more predictable, uniform bond line than a thick, variable spot-fixed bed. This is why the observed tensile adhesion sits at roughly double the code minimum.
Where it is used
- Fixing ceramic and earthenware wall tiles in interior kitchens and bathrooms
- Laying vitrified floor tiles up to 4 square feet in residential rooms
- Tiling interior balconies and covered terraces over cured cement screed
- Bonding tiles to cement plaster, concrete and other absorbent cementitious backgrounds
- Standard-format ceramic floor tiling in bedrooms, living areas and passages
- Pre-filling minor surface defects and level variations up to 5 mm ahead of tiling
- Renovation tiling where a certified thin-bed adhesive replaces sand-cement mortar
- General residential tile-setting where a C1T standard-set grade meets the specification
Key advantages
- Certified to both IS 15477-2019 Type-1 ‘T’ and EN 12004-2:2017 C1T for specification confidence
- Tested tensile adhesion of at least 1 N/mm2, roughly double the 0.5 N/mm2 code minimum
- Only clean water is added on site, removing sand-quality and mix-ratio variability
- Self-curing chemistry avoids separate water curing of the bond line
- Thin 3 mm bed uses far less material per square metre than thick-bed mortar
- Long pot life of about 110 minutes gives generous working time in a single mix
- Creamy, smooth consistency combs cleanly and holds trowel ridges for full contact
- Economical 20 kg and 40 kg bag options suit both small jobs and larger residential floors
Limitations & considerations
- Indoor use only; it is not intended for exterior facades or fully exposed areas
- Rated for tiles up to 900 cm2 (30×30 cm); larger tiles need the double-buttering technique
- Being a rigid C1 standard-set grade, it lacks the flexibility of C2S1/S2 adhesives for deflecting or heated substrates
- Not suitable for application over metal or timber surfaces
- Not the correct choice for large-format vitrified, natural stone or continuously wet/submerged zones
- Cementitious substrates must be fully cured and dried for 2-6 weeks before tiling, which the programme must allow for
Selection & best practice
Start with a sound, clean, dry background free of dust, laitance, oil and efflorescence, and rough up any smooth or dense surfaces. On absorbent backgrounds or in hot weather, pre-dampen the surface but leave no standing water and let it become touch-dry before combing on adhesive. Gauge the powder into clean cold water at 0.23-0.25 by weight (about 4.6-5.0 litres per 20 kg bag), mix with a slow-speed drill under 500 rpm until lump-free, let it mature for 2-3 minutes, then remix briefly. Comb out only as much as can be tiled within the open time of over 15 minutes, choosing the notch size to suit the tile: a 6 mm trowel for small tiles, 8 mm for medium and 10 mm for large, at a minimum 3 mm bed. Bed each tile with firm sliding pressure to collapse the ridges and achieve full contact; if a skin has formed, scrape that adhesive off and re-comb fresh. Final adjustments should be made within about 8 minutes. Wait 24-36 hours before grouting floors and 4-6 hours for walls, and keep the finished work protected from rain, freezing or extreme heat for the first 12-24 hours, allowing roughly 14 days before full traffic.

How we position Sika SikaCeram-50 Tilofix
SikaCeram-50 Tilofix is the certified standard-set (C1T) rung of the SikaCeram tile-setting system, best suited to everyday indoor ceramic and small vitrified work. When a project moves beyond its envelope, the natural upgrades within the same Sika family are the flexible SikaCeram-288 Flex S1 for large-format tiles, low-absorption porcelain and areas subject to movement or direct water, and the SikaCeram range of cementitious and epoxy tile grouts to finish the joints, with SikaCeram floor levellers to true up the substrate first. Where a substrate needs waterproofing before tiling, pair it with a cement-based or acrylic Sika waterproofing system, and seal any structural cracks with a Sikadur epoxy. On the wider shelf Space Arc carries, a specifier who has standardised on Fosroc will find the equivalent standard-set counterpart in the Fosroc Nitotile GP / C1-grade family, with Roff and other brands offering comparable C1 adhesives; the honest guidance is that all of these are interchangeable at the C1 tier, so the choice usually comes down to approved-vendor lists, availability and price rather than performance. Our team can size the correct grade against the tile type, format and exposure so you are neither under-specifying a wet area nor paying for flexibility a dry residential floor does not need.
