To achieve the effect of a concrete worktop we have two solutions - make a concrete kitchen worktop cast in architectural concrete or a worktop covered with a thin layer of microcement. A microcement kitchen worktop, although achieving a similar visual effect to a concrete worktop, offers additional benefits such as easier application, lighter weight and the ability to cover a variety of surfaces, including OSB.
Concrete worktop or microcement-covered worktop?
MICROCRETE WORKTOP
A concrete worktop is quite heavy and requires the use of high-grade concrete (we discourage the use of market mixes). In addition, a concrete kitchen countertop should be reinforced with steel mesh and additionally with dispersed fibre (glass or polypropylene). First, the form for the worktop is built, poured with concrete, trowelled and then waits a minimum of 24-48 hours. The formwork is then removed and sanded to the desired effect. The final step is impregnation, which will make the surface smooth, protect it from dirt and reduce the absorbency of the concrete. You can use our ready-mixed architectural concrete, ARCHIFEST, to make a concrete worktop.
If you want a quicker result, you can cover the worktop - whether it's wooden, chipboard, OSB or MDF - with microcement. First, the surface should be primed and then two thin layers of microcement should be applied with a trowel at intervals of about 3 hours. Once dry, one layer of microcement as well as the other is sanded. If you want a uniform surface, you should do it very gently. On the other hand, if you want to achieve an effect as close as possible to natural concrete, you use abrasions and burnishes. Finally, as with the fair-faced concrete worktop, the microcement worktop must be varnished.
By the way, we must warn against the idea that sometimes comes to customers' minds when it comes to concrete countertops. Some people try to combine both techniques and instead of microcement use ordinary concrete to cover the countertop. We say straight away that such concrete will not adhere to the surface, and if it even adheres to it to some extent, it will crumble and fall off at the slightest impact. Microcement is a special mixture containing polymers that provide excellent adhesion, flexibility and water resistance and in this case cannot be replaced by sand with cement.
The most important advantages of a microcement worktop are:
LIGHTWEIGHT CONSTRUCTION
Microcement is only a thin decorative layer that is applied to the existing surface, which makes it much lighter than a countertop cast in concrete. The lightness of the element we cover with it is particularly important if, for example, we want to make tables with a concrete top in a restaurant or café that will be frequently rearranged).
ANTIBACTERIAL PROPERTIES
A microcement table top, coated with a varnish containing NANO SILVER PLUS, which contains silver ions, will provide additional protection against bacteria and other microorganisms. Thanks to its silver ion content, NANO SILVER PLUS has antibacterial properties that create a hygienic protective coating on the surface.
MOISTURE RESISTANCE
Our HYDROFEST microcement is water-resistant, making it ideal for use in wet areas such as bathrooms and kitchens, including kitchen worktops.
UNIFORM SURFACE
Microcement is a material that allows you to create a uniform surface on your worktop, without joints. This not only affects the aesthetics of the finish, but also eliminates the problem of particle and dust accumulation.

MICROCEMENT KITCHEN WORKTOP
Microcement for the kitchen worktop is a solution that not only gives the interior an unconventional look, but is also durable and easy to maintain. It is a material that can be used on a variety of surfaces, from OSB to ceramic tiles, giving a uniform concrete look. What's more, the microcement system is resistant to moisture, making it an ideal choice for kitchens. Additionally, by protecting the microcement kitchen worktop with a varnish containing silver nanoparticles, you can provide protection against bacterial growth and keep the surface of the kitchen worktop hygienic, which is important in a place where meals are prepared daily.
How to make a kitchen worktop from OSB, MDF or chipboard
Creating a microcement-covered board kitchen worktop is a process that requires careful preparation and the correct application of materials. Here are the steps that need to be taken:
1. Preparing the OSB, MDF or particle board that will be the base of the kitchen worktop.
2. Priming the surface of the board
3. Application of microcement on the board (2 layers, sanded when dry)
4. Protection of the worktop with a sealer with a special additive with antimicrobial properties.
How do I care for my microcement worktop?
Proper care and following the manufacturer's recommendations have a significant impact on the functionality and durability of the finishing elements, therefore it is worth learning and applying practical tips, which will help to maintain the attractive appearance and appropriate durability of the surface.
In the case of a microcement worktop, it is important to:
Using cutting boards: do not cut directly on the countertop with a knife, as indentations may appear on the surface.
Using pads under hot pots and dishes.
For the kitchen worktop: spilled vinegar, lemon juice, oils and similar liquids should be wiped up as soon as possible, as they can damage the paintwork.
For bathroom worktops: the microcement surface should not come into contact with substances such as nail polish remover, hydrochloric acid or ammonia, as these can also damage the lacquer.
For care and cleaning, use a mild detergent such as washing-up liquid or dedicated microcement care products such as FESTCLEANER or POWER-FEST.
