Extremely hard water, constantly high humidity and fine dust can quickly make a bathroom look dirty.

Stubborn limescale stains, mould that eats into the grouting, toothpaste marks in the sink and sticky fine dust can be enough to drive you to despair. Cleaning is an immense task, and the mould can even pose a health risk.

All this can be avoided with seals from KAIKA TECH.

Sealing bathtubs, showers, washbasins and toilet ceramics primarily serves to optimise hygiene, cleaning efficiency and value retention. As sanitary ceramics are the most heavily used surfaces in the home, our sealant provides a crucial protective shield against daily exposure to germs, mould, limescale, soap residues and dirt particles. 

Here are the main reasons for sealing your bathroom:

1. Hygiene and bacteria protection

• Pore sealing: Micro-irregularities and pores in the ceramic surface are sealed by the sealant.

• Protection against germs: As dirt and moisture can no longer penetrate deeply, bacteria and mould are deprived of their livelihood. This is a massive hygiene advantage, especially in the toilet and on the damp edges of washbasins. 

2. Massive time savings when cleaning (‘easy to clean’)

• Lotus effect: Water, limescale and soap residues simply roll off.

• Effective cleaning: Dirt only sticks to the surface and can usually be removed with clear water and a soft cloth. 

3. Protection against limescale and discolouration

• Limescale resistance: In regions with hard water, limescale stains do not burn in as deeply, which keeps the ceramic permanently shiny.

• Protection against aggressive substances: The sealant protects the ceramic from discolouration caused by cosmetics, hair dye or aggressive cleaning agents. 

4. Value retention and aesthetics

• Lasting shine: Dull ceramic is visually refreshed by the smoothing layer and given a brilliant deep shine.

• Durability: While simple nano sealants last around 6–12 months, professional ceramic sealants (two-component systems) can last up to 5 years or longer, depending on care. 

5. Environmental and material protection

• Fewer chemicals: As dirt hardly sticks to the surface, there is no need for harsh, environmentally harmful abrasives or acids.

• Surface protection: By avoiding abrasive cleaners, the glaze on the ceramic is not mechanically worn away.

Conclusion: Our sealing in the bathroom will be particularly worthwhile for households that value quick cleaning and maximum hygiene while maintaining a high-quality appearance.

Sticky hobs, sticky and greasy extractor hoods, scratched work surfaces, calcified sinks and taps are a source of annoyance in almost every kitchen.

After our sealing treatment, you can relax in the kitchen and let off steam. Cleaning is then a piece of cake.

A nano or ceramic sealant in the kitchen offers similar advantages to those in the bathroom, but is specifically designed to meet the challenges of this area: hygiene, stain resistance, heat resistance and significant time savings when cleaning. 

Why sealing is a good idea in the kitchen:

1. Maximum hygiene and antibacterial effect

Kitchen surfaces are constantly in contact with food, germs and liquids.

• Germ reduction: Sealants (especially ceramic) create an extremely dense, non-porous surface on which bacteria and mould cannot adhere or multiply.

• Safe handling of food: High-quality ceramic coatings, such as those used in cookware, are safe for contact with food and do not contain any harmful chemicals (such as PFAS). 

2. Protection against stains, acids and chemicals

• There are many substances in the kitchen that can cause stains or damage surfaces (e.g. coffee, red wine, turmeric, citric acid, vinegar, harsh cleaners).

• Stain protection: The hydrophobic (water-repellent) and oil-repellent layer prevents liquids and dyes from penetrating porous surfaces (such as natural stone or certain tiles).

• Chemical resistance: Ceramic sealants in particular are highly resistant to acids and alkalis used in cooking or cleaning. 

3. Easier cleaning (‘easy-to-clean’ effect) and time savings

• The smooth, dirt-repellent surfaces make kitchen maintenance much easier.

• No scrubbing: dirt, grease and splashes only stick loosely and can usually be easily wiped away with a damp cloth.

• Fewer water spots: water rolls off stainless steel or ceramic sinks, minimising unsightly limescale and water spots.

• Reduced cleaning agent consumption: you need fewer aggressive and expensive cleaning agents. 

4. Heat resistance and scratch protection

• Ceramic sealants in particular are characterised by high heat resistance, which is a great advantage in the kitchen.

• Heat protection: Sealed worktops (e.g. made of natural stone or ceramic) are more resistant to heat from hot pots.

• Scratch resistance: The additional hardness layer reduces micro-scratches caused by cutlery, crockery or chopping boards. 

Our ceramic sealant is suitable for a wide range of kitchen surfaces:

• Worktops: Whether granite, ceramic, stainless steel, wood or certain plastics.

• Sinks: Stainless steel sinks remain streak-free and more hygienic.

• Hobs: Gas, ceramic or induction hobs are easier to clean of burnt-on food.

• Tiles and tile joints: Splash guards on the wall remain cleaner and germ-free.

• Household appliances: The surfaces of refrigerators or ovens (especially stainless steel) become fingerprint-resistant and shiny. 

The choice between nano and ceramic sealing depends on the desired durability: nano lasts for a shorter period and needs to be refreshed, while ceramic is a long-lasting, almost permanent solution that is applied professionally. We offer both, but recommend the higher-quality ceramic sealing. 

Both nano and ceramic sealants offer significant advantages over untreated surfaces in outdoor areas (terraces, balconies, facades).

However, the choice of method is crucial, as outdoor areas are exposed to extreme weather conditions. 

Why use nano or ceramic sealing for outdoor areas?

The general advantages are similar in both cases:

• Protection from the weather: Both provide effective protection against moisture, frost, UV radiation, acid rain and temperature fluctuations.

• No algae/moss growth: The smooth surface prevents algae, moss and fungi from adhering.

• Easier cleaning: Dirt, bird droppings and deposits simply roll off (lotus effect or beading effect), which minimises the cleaning effort.

• Value retention: The materials (plaster, concrete, wood, tiles) remain beautiful and intact for longer. 

Ceramic vs. nano sealing in outdoor areas, the decisive difference: 

In outdoor areas, where surfaces are permanently exposed to UV radiation, rain, sea air, snow and mechanical stress (terrace floors), durability plays the most important role. This is where our ceramic sealing has clear advantages.

Arguments in favour of our ceramic sealing (recommended for outdoor areas):

Due to the harsh outdoor conditions, our ceramic sealing is the better choice:

• Permanent protection: The permanent bond with the substrate (e.g. concrete, stone, plaster) offers significantly longer-lasting protection against weathering and abrasion.

• Extremely resistant: It forms a ‘sacrificial layer’ that is harder than the original material and more resistant to mechanical impact (walking on the terrace), road salt and aggressive environmental influences.

• Constant UV protection: The high UV stability ensures that our ceramic sealant does not degrade as quickly.

Arguments in favour of our nano sealant

• Our nano sealing is a good, more cost-effective alternative for users who are willing to refresh the treatment regularly (annually). It is ideal for mineral surfaces where simple, diffusion-open impregnation is desired.

Conclusion:

Due to mechanical stress and weather influences, our durable ceramic sealing is worthwhile for terraces and balconies. For façades, depending on your budget and desired maintenance interval, both our high-quality nano impregnation and our ceramic sealing may be suitable, with the latter minimising maintenance for years to come. However, after our ceramic sealing, a new coat of paint is out of the question for the next 5–10 years, as the paint will no longer adhere to the base.

Both ceramic and nano sealants are excellent methods for protecting windows, conservatories, pavilions, carports and newly installed PV systems more effectively against environmental influences, simplifying cleaning and increasing the longevity of these components.

The main reason for applying our technologies to these specific surfaces is their susceptibility to heavy soiling and weather damage.

Common advantages of our nano and ceramic sealants in these areas:

• Extreme ‘easy-to-clean’ effect: The biggest advantage – dirt, dust, bird droppings, tree resin and insect remains hardly stick to the surface and can often be removed simply with clear water or a cloth, without having to scrub.

• Reduced water and limescale stains: This is particularly important for large glass surfaces such as conservatories, windows and solar panels. The water rolls off, leaving fewer limescale stains and ensuring a clearer appearance.

• Protection against environmental pollution: Our sealant protects surfaces from UV radiation, acid rain and oxidation, which prevents fading or tarnishing of frame materials (e.g. aluminium, painted wood, plastic).

• Less cleaning effort: Large, hard-to-reach surfaces (such as conservatory roofs, high windows or PV systems) need to be cleaned less often and more easily.

The special case: photovoltaic systems

Sealing is particularly beneficial for PV systems as it directly influences energy efficiency:

• Maximum solar radiation: a clean surface absorbs more sunlight. Sealing keeps the glass of the modules clean for longer and maximises light transmission. Studies show that sealed modules achieve efficiency increases of more than 10%.

• No ‘hot spotting’ due to dirt: Dirt edges or bird droppings can lead to uneven heating (hot spots), which reduces performance and can damage the modules in the long term. Sealing prevents stubborn deposits.

• Less professional cleaning required: Expensive, professional cleaning of solar systems is required less frequently.

The choice between nano and ceramic sealing

For these areas of application, which primarily involve glass, painted metals, plastics and wood, both methods offer advantages. The decision depends largely on the desired durability and budget.

Recommendation:

For windows that are cleaned regularly, our nano sealing can be a good and simple DIY solution if you are prepared to refresh it annually. However, this will be more expensive in the long run than our ceramic sealing, as it does not need to be refreshed for years.

Our ceramic sealant is the superior choice for conservatories, pavilions, carports and, in particular, PV systems. Its high resistance to UV radiation and extreme durability minimise maintenance requirements over many years and ensure the long-term efficiency of solar systems.
