Sanifresh Alpha goes a step further than standard antibacterial paint. It is a premium anti-bacterial and anti-viral semi-elastomeric interior paint with inorganic active agents, tested against organisms including MRSA, E. coli and enteroviruses linked to Hand, Foot and Mouth Disease. C&S Projects supplies and applies it across Colombo and the Western Province for clients needing hygiene performance and crack resistance in one coating.
The mechanism
Sanifresh Alpha is a water-based, reactive-curing acrylic resin emulsion containing an inorganic anti-bacterial agent as its main active element, generating antibacterial action through active oxygen at the coated surface. Documented performance covers strong action against MRSA, Pseudomonas aeruginosa, Escherichia coli, Candida albicans, and Coxsackievirus and Enterovirus strains associated with Hand, Foot and Mouth Disease.
That range matters for childcare centres, clinics and food-contact environments in Sri Lanka, where HFMD outbreaks are a recurring seasonal concern. Its semi-elastomeric property also bridges surface and hairline cracks, which standard antibacterial paints do not address.
To set expectations honestly: a coating supports hygiene, it does not replace it. Cleaning regimes and the wider infection prevention and control measures a facility already runs remain the primary defence. However, wall surfaces are large and constantly touched, so their performance genuinely contributes.
The crack-bridging half is easy to underrate. Buildings in Colombo move with humidity and temperature swings, and a rigid hygienic film simply splits along those movements. Once cracked, a surface is no longer cleanable in the way an audit expects.
HFMD is the clearest local example of why the anti-viral side is specified. Outbreaks move quickly through pre-schools and childcare centres, and transmission is largely by contact with contaminated surfaces. Therefore parents and administrators increasingly ask what the walls themselves are coated with.
Food facilities ask a different question. There the concern is bacterial rather than viral, and the surfaces are washed down aggressively with alkaline detergents. As a result the coating has to survive chemical cleaning without chalking, which is where a reactive-curing acrylic outperforms a conventional emulsion.
Both cases share one requirement: the surface must stay non-porous. A porous wall traps organic soil, and no active agent compensates for a film that has broken down. Because of that, we treat film integrity as the first priority and the active chemistry as the second.

Application can be scheduled in occupied buildings with limited downtime.
Best fit
The specification suits buildings where hygiene is audited and the structure also moves — older clinics, school blocks, kitchens and care facilities. These are exactly the settings where a rigid coating cracks and a flexible one keeps its integrity.
Homes are on the list for a reason too. Households with a newborn, an elderly relative or someone immunocompromised often ask for the same standard used in clinics, particularly for kitchens, bathrooms and children's rooms where surfaces get touched constantly.
Older buildings are the other common case. Many Colombo schools and clinics were built decades ago and have settled since, so the walls carry a history of fine cracking that a rigid coating simply re-opens.
Where a facility needs a general-purpose hygiene coating rather than broader-spectrum performance, our antibacterial paint for hospitals page covers that option and where each one fits.
Explore the range
Sanifresh Alpha sits within our wider paints & textures range — hygiene coatings, low-VOC interiors, exterior systems, enamels and decorative textures, supplied with application by our own teams.
How we work
Because Sanifresh Alpha is low-VOC and low-odour, C&S Projects can schedule application in occupied buildings with limited downtime. Our teams follow the manufacturer's substrate guidance for concrete, calcium silicate board, slate board and plasterboard, and confirm surface soundness before coating.
Film thickness is the detail that decides whether the elastomeric performance is real. Crack-bridging depends on achieving the specified thickness across the full surface, not just in the easy open areas. Therefore we apply to the stated coat count rather than stretching material to cover more square footage.
Existing cracks are assessed before we quote. Live structural movement needs repair, not a flexible topcoat — our surface preparation range covers those repair products, and our painting service covers phased application around a working facility.
Ventilation during application matters even with a low-odour system. In sealed, air-conditioned wards and kitchens we arrange temporary airflow so each coat cures evenly, because a film that dries unevenly will not deliver consistent thickness across the wall.
We also record batch and colour references for every facility we coat. As a result a ward or kitchen needing a localised touch-up two years later can be matched exactly, rather than recoating a whole room to hide a visible patch.
How it compares
Many antibacterial paints claim resistance to common bacteria only, without published anti-viral performance or crack-bridging properties. That is adequate for a stable, modern substrate in a low-risk setting.
Sanifresh Alpha's documented action across a wider range of organisms, combined with elastomeric flexibility, makes it the stronger specification where a facility manages both hygiene compliance and building movement. For interiors without a hygiene requirement, see our low VOC interior paint page.
Local coverage
We supply and apply hygiene coatings across Colombo and the surrounding suburbs — Rajagiriya, Nugegoda, Battaramulla, Nawala, Dehiwala and Kotte — as well as schools, clinics and kitchens in Colombo 05 and 07. Because our stores sit on Buthgamuwa Road in Rajagiriya, sites across Sri Jayawardenepura Kotte are quick to service when a term break or shutdown window is short.
School and childcare work is almost always scheduled into holidays, which compresses the programme. Therefore we agree the sequence and manpower before committing to a handover date, rather than discovering halfway through that a wing cannot be finished in time.
Clinics and food premises work the opposite way, around night shifts and wash-down windows rather than holidays. For example, a commercial kitchen in Colombo 05 may only release its walls between midnight and five, so we size the crew to the window instead of stretching the job across weeks.
Having supplied and applied coatings across the Western Province since 2022, we have learned which older buildings need crack repair first. As a result we survey and say so plainly, instead of coating over movement that will reappear, because a flexible film masks a moving crack for a season at best. See our completed projects for context.
Quick answers
No. It is one layer alongside cleaning protocols and ventilation, and we present it that way. What it does is keep a large, frequently touched surface hygienic and cleanable between the cleaning cycles a facility already runs.
It depends on the building. Where the substrate is stable and risk is low, standard antibacterial paint is adequate. Where a facility faces both hygiene audits and hairline cracking, the elastomeric option avoids paying twice.
Yes, and that is how most childcare and school work is scheduled. We agree sequencing and manpower upfront so the programme fits the break, because a partially finished wing is not a usable handover.
“Our building is older and the walls had hairline cracks everywhere. C&S Projects repaired them first, then coated. Two years on it still cleans up properly and nothing has re-cracked.”
