Tadelakt (lime) or microcement? Choose your bathroom wall covering
Tadelakt or microcement: which one will best enhance your bathroom?
The idea of renovating your bathroom with lime keeps coming back to you. It's an exciting project that would modernise this central space in the home, while adding a personal, eco-friendly touch. Among the many materials available, two options stand out for their aesthetics and performance: lime and microcement. Yes, the latter has also caught your eye — so maybe your heart is still hesitating a little…
Tadelakt and microcement aren't the only options: compare all the bathroom wall coverings before deciding.
These two finishes offer must-have solutions to transform your bathroom.
Lime, with its natural, textured look, is appreciated for its ability to create a warm, rustic atmosphere. Beyond its authentic appearance, it has breathable properties — ideal for humid spaces like the bathroom. On the other hand, microcement, known for its modern, refined, smooth finish, stands out for its durability and ease of maintenance, making it a preferred choice for minimalist renovation projects.
In this comparison, we're going to explore the features and benefits of these two materials to help you make an informed decision. Whether you're looking for a traditional or contemporary style, lime and microcement each offer unique possibilities to enhance your bathroom.
If in the end you go for microcement, the microcement kit for bathroom lets you apply it yourself over walls, shower and sink, without removing the tiles.
1. Tadelakt: the lime plaster for bathrooms
When people look to cover their bathroom with lime, they're almost always thinking of tadelakt: the lime plaster of Moroccan origin, polished and burnished with black soap, which waterproofs the surface and leaves that undulating finish so characteristic of hammams. Its Italian cousin is venetian plaster, with its marble effect. It's a noble, natural, breathable covering, and everything that follows about lime applies to it.
Advantages of lime for the bathroom
- Breathable properties and moisture resistance
Lime is especially suited to humid environments like bathrooms. Thanks to its breathable properties, it allows walls to “breathe”, which prevents condensation and limits the appearance of mould. This ability to regulate moisture makes lime ideal for spaces where water vapour is very present, ensuring a healthy, long-lasting environment.
- Natural, textured aesthetics
For those looking to create a warm, rustic, or Mediterranean atmosphere, lime offers a unique look. Its soft texture and natural nuances add a touch of authenticity to any space. Whether in neutral shades or tinted, lime can be customised to suit your tastes while maintaining its artisanal, living character.
- Eco-friendly, non-toxic solution
Made from natural raw materials, lime is an environmentally friendly choice. It contains no harmful chemicals, making it an ideal alternative for those concerned about indoor air quality and ecological impact. In addition, it is biodegradable and can be recycled, reducing its environmental footprint.
- DIY-friendly application
Lime, while requiring a bit of technique, is relatively easy to apply for those who enjoy handling their renovation projects themselves. With proper surface preparation and a good application method, it's possible to transform the bathroom into a personalised space without resorting to complex or costly work.
- Adaptability to different substrates
Lime can be applied over various types of surfaces, whether plaster, brick, or concrete walls. This versatility makes it usable in almost any bathroom, even those with irregularities or defects to correct. Its ability to adhere to different substrates makes it a very flexible material for your renovation projects.
Drawbacks of lime for the bathroom
- Regular maintenance required
Although lime is moisture resistant, it requires more frequent maintenance than other materials such as microcement. The surface can degrade over time, especially in very humid areas, and may need touch-ups to keep its original appearance. In addition, extra protection may be necessary in areas directly exposed to water, such as showers.
- Less resistant to impacts and scratches
Compared to finishes such as microcement, lime is more fragile when it comes to impacts and scratches. This can be an issue in spaces where walls or surfaces are frequently exposed to knocks, such as narrow areas or homes with children. This fragility can lead to visible marks and require occasional repairs.
- Requires technical application
Although lime is suitable for DIY enthusiasts, it does require some skill to apply correctly. Poor surface preparation or clumsy application can cause cracks or an uneven finish. For this reason, it's recommended to have a good grasp of the technique or to hire a professional to ensure the best possible result.
- Longer drying time
Unlike more modern materials, lime has a relatively long drying time, especially in humid environments like bathrooms. This can slow down the renovation project and make the room unusable for several days, particularly if multiple coats are needed.
- Less suited to contemporary styles
While lime is ideal for natural or rustic atmospheres, it fits less well with renovation projects aiming for a more modern or minimalist style. Its textured, matte look may not suit those looking for a smooth, clean finish — often associated with contemporary styles and microcement.
2. Microcement for the bathroom: modernity and practicality
Advantages of microcement for the bathroom
- Exceptional resistance to water and moisture
Microcement is especially suited to humid environments like bathrooms. Thanks to its continuous, grout-free structure, a microcement bathroom prevents water and mould buildup, making it an ideal option for showers and floors. Its natural water resistance helps maintain a clean, healthy space.
- Smooth, modern finish
For those looking for a minimalist, contemporary style, microcement offers a smooth, seamless finish that creates a sense of spaciousness and elegance. It fits perfectly with modern designs and also creates visual continuity between walls and floors. In addition, it's available in a wide range of shades and finishes (matte or satin), allowing you to customise the look to your preferences.
- High durability and impact resistance
Microcement is an extremely durable material, resistant to impacts, scratches, and wear. It withstands frequent traffic and knocks very well, making it a particularly smart choice for heavily used bathrooms. Once applied and protected with a varnish or wax, it keeps its appearance intact for many years without needing frequent touch-ups.
- Easy maintenance
The maintenance of microcement is simple and undemanding. Regular cleaning with a gentle product is enough to keep its shine. In addition, the absence of grout lines makes cleaning much easier and prevents dirt buildup. This makes it a practical, hygienic material, especially suited to environments like bathrooms.
- Direct application over most surfaces
One of the great advantages of microcement is that it can be applied over existing surfaces (tiles, with Smart Jointer and Smart Primer PLUS; plaster, concrete). This reduces both cost and project duration, since there's no need to remove the original coverings. This adaptability makes it an excellent option for those who want to modernise their bathroom quickly and effectively.

- Eco-friendly formulation
Our microcement, with its “water-based” formulation, is part of an environmentally friendly approach. Unlike other coatings that use solvents or harmful chemicals, Smartcret minimises ecological impact while still offering a high-quality solution. This microcement, free from toxic substances, preserves indoor air quality and is therefore perfectly suited to eco-responsible renovation projects. Choosing Smartcret means being environmentally conscious without compromising on aesthetics or performance.
Drawbacks of microcement for the bathroom
- Technical application
Microcement can be difficult to apply correctly, especially due to the risk of cracking. However, Smartcret kits, with their detailed step-by-step guide, are designed for beginners, minimising these risks and ensuring a long-lasting result.
- Perceived cost
Although microcement is often more expensive, this extra cost is usually due to professional installation. Smartcret's Do It Yourself kits make this material more accessible for DIYers and significantly reduce the investment.
- Application time
Applying microcement takes time because of drying times. However, Smartcret kits make it possible to plan each stage effectively, ensuring a controlled process and a high-quality result. In addition, this mineral coating avoids having to remove the old covering, which more than makes up for it by reducing the overall duration of a clean renovation project.
- Flexibility for touch-ups
Touch-ups require a specific process, but microcement needs fewer interventions than materials such as paint or lime, thanks to its durability and resistance to wear.

3. Lime vs. microcement comparison by different criteria
Aesthetics and style
Lime offers a natural, textured finish — ideal for creating a warm, authentic atmosphere. It is especially suited to rustic, Mediterranean, or bohemian-style bathrooms, where an artisanal look is desired.
By contrast, microcement seduces with its smooth, modern look — perfect for minimalist and contemporary bathrooms. Its lack of grout lines creates visual continuity that makes the space feel larger, while offering a clean, sophisticated look. You may also be drawn to the variety of microcement colours.
Durability and maintenance
Lime, although durable, requires more regular maintenance to preserve its appearance, especially in humid environments. It can degrade more easily and sometimes needs touch-ups.
Microcement, on the other hand, is extremely resistant to impacts, scratches, and wear. It requires little maintenance and offers long-term durability, while also being easy to clean thanks to the absence of grout lines.
Installation
Applying lime is relatively simple and accessible for DIYers, although it does require some technique to achieve the desired finish.
Microcement, for its part, is more technical to apply. However, Smartcret kits with their step-by-step guide greatly simplify the task for beginners. In addition, microcement can be applied directly over the old covering, avoiding demolition and removal work.
Environmental impact
Lime is a completely natural, eco-friendly material with no harmful chemicals, making it an excellent option for those looking to minimise their environmental impact.
Smartcret microcement, with its water-based formula, also offers an environmentally friendly alternative without toxic solvents. Therefore, both materials are suitable for eco-responsible renovation projects.
One more criterion, decisive in practice: who applies it. Tadelakt is an artisanal craft: it demands a specialist applicator, carbonation times and polishing soap, and its price depends entirely on that labour. Smartcret's ready-to-use microcement is designed for you to apply yourself, with bathroom kits at a fixed price and with all the material included.
4. Application: key steps for installing lime and microcement
Lime:
- Surface preparation: clean the wall well, fill cracks and irregularities to obtain a sound base.
- Primer coat: apply a specific primer to ensure better adhesion of the lime.
- Applying coats: apply two thin coats of lime, smoothing or texturing depending on the desired effect. Wait for full drying between each coat.
- Drying: let it dry completely before exposing the surface to moisture.
Microcement:
- Substrate preparation: make sure the surface is clean and flat, then apply an adhesion primer to promote bonding.
- Applying coats: spread two coats of microcement with a trowel, smoothing well with each pass. Lightly sand between coats for a perfect finish.
- Finish: apply a varnish or wax to protect the microcement from water and scratches, especially in wet areas such as showers.

Frequently asked questions: tadelakt or microcement
Does tadelakt work for the shower?
Yes, that's its historic use in hammams. Properly applied and with its maintenance soap it's waterproof. But it demands an expert applicator and periodic maintenance with black soap; microcement achieves the seamless shower with less craft skill and a varnish seal that's simpler to maintain.
Which is easier to maintain?
Microcement: water and neutral soap, and renew the varnish when it's due. Tadelakt calls for periodic re-soaping and more care with cleaning products. You have the guidelines in the cleaning and maintenance guide.
Which is cheaper?
Applied by a professional, both depend on labour rates in your area, and tadelakt usually ends up higher because of the hours of craftsmanship involved. The real difference is in DIY: ready-to-use microcement you can apply yourself with a fixed-price kit; tadelakt is not a first-timer's material.
In summary
Choosing between lime and microcement to renovate your bathroom depends above all on the style you want to create and your priorities in terms of durability and maintenance. Lime, with its natural, textured look, is perfect for those seeking a warm, authentic atmosphere while prioritising an eco-friendly material. By contrast, microcement appeals thanks to its modern aesthetics, durability, and ease of maintenance — especially in humid environments like bathrooms.
With Smartcret microcement kits, applying this mineral coating becomes accessible to everyone — even beginners — offering an affordable, practical solution. Whether you choose lime or microcement, both materials will bring real character to your bathroom while meeting your expectations for aesthetics and performance.
