Consumption of Concrete Effect Plaster
The average consumption is approx. 1 kg per m² for one layer. Consumption depends on the prepared substrate and the thickness of the applied concrete effect plaster (one layer approx. 1 mm).
From a single 20 kg bucket, you can prepare approximately 10 m² in two layers. The measured values are provided under standard conditions — for uneven surfaces, it is recommended to order more material.
How to Prepare and Apply Concrete Effect Plaster
Although concrete trowel finish is primarily a design and functional element suitable for almost any interior, its application is really easy and can be managed by anyone — all you need is a Venetian trowel and a paintbrush.
Surface Preparation and Primer Application
The concrete effect plaster can be applied to any absorbent surface (old plaster, drywall, stucco, lost formwork, old concrete, etc.). Concrete effect plaster should not be applied on frozen, wet, highly sunlit surfaces, or in fog or rain. The surrounding temperature should be between 5–20°C.
Clean the prepared surface from grease and dirt. Fill larger cracks or irregularities with mortar or adhesive. Minor irregularities will be covered during the application of the concrete trowel finish. Included in the package is a primer for the concrete effect plaster, enhancing the adhesion of the concrete effect plaster and increasing its mechanical resistance.
Mix the primer and apply it to the prepared and cleaned surface with a paintbrush and let it dry for about 2 hours.
Mixing Concrete Effect Plaster
Concrete effect plaster must be thoroughly mixed before application, either manually or with a low-speed mixer (~400 rpm) to achieve a uniform consistency. If the trowel finish is thick, it can be diluted with a little water - 1-2 dcl of water.
Applying the First, Base Layer
Two layers of concrete effect plaster should be applied to the finished and prepared surface.
Apply the first layer with a maximum thickness of 1–2 mm using a Venetian trowel. The concrete effect plaster should be all over the wall covering the whole area of the wall. The first layer should dry for about 3–6 hours.
Application of the Second Textured Layer
Apply the second layer again using a Venetian trowel. The second layer should be done with short, irregular movements - circular, vertical, or horizontal. In this step, there are no limits to imagination, and it always depends on preferences for how you want the trowel finish to look.
To achieve a shading/marbling effect, it is necessary to vigorously rub selected areas while holding the trowel flat with minimal inclination to the surface. If the trowel finish surface is wet and pliable during application, you will achieve a uniform and smooth surface.
If you are working with a fresh surface, you can achieve various effects, for example, by imprinting screws, wooden boards, and similar techniques.
The second layer should dry for approximately 6–12 hours.
Application of the Final Lacquer
The final lacquer increases the longevity and durability of the concrete trowel finish. Mix the dense lacquer and apply it using a paintbrush. Lacquer consumption is approximately 0.1 kg per 1 m² of concrete trowel finish — in a typical environment, apply 1 to 2 layers of this lacquer.
If you are interested in enhancing the shine of the concrete trowel finish, mix the standard lacquer with glossy lacquer.
Application of Lacquer in Bathrooms and Shower Corners
In the case of using concrete trowel finish in areas with increased humidity or water contact, we recommend applying a hydrophobic/water-resistant lacquer to ensure enhanced protection against water. This water-resistant lacquer is suitable for bathrooms or shower corners. You should apply this water-resistant lacquer as the 3rd layer of lacquer (under this lacquer, always apply 2 layers of standard lacquer).
For more information, you can refer to our article Application of Concrete Trowel Finish.
The lacquer consumption is approximately 0.1 kg per 1 m² of concrete trowel finish — in a typical environment, apply 1 to 2 layers of this lacquer, and for shower corners, apply the 3rd layer of the hydrophobic lacquer.
We supply the concrete trowel finish including primer (2.5 kg), and final clear lacquer (1,5 kg).

FAQ
Hermann's design concrete plaster is a surface material for both indoor and outdoor areas. It offers an industrial concrete look and can be applied to walls, bathrooms, shower cabins, stairs, kitchen counters, and other surfaces.
The concrete plaster is mechanically resistant, easy to apply, temperature- and abrasion-resistant, and can be used on various substrates such as old plaster, drywall, or concrete. It offers a luxurious appearance and is colorfast.
Der durchschnittliche Verbrauch beträgt etwa 1 kg pro m² für eine Schicht. Mit einem 20-kg-Eimer können Sie ca. 10 m² in zwei Schichten vorbereiten.
For application, a Venetian trowel and a paintbrush are sufficient. Before application, the surface must be cleaned of grease and dirt, cracks filled, and a primer applied.
First, apply the primer. Then mix the plaster. Apply a first layer, let it dry, and then apply a second textured layer. Finally, apply the final varnish.
Yes, concrete plaster is suitable for bathrooms and kitchens due to its resistance to water and grease. For bathrooms, it is recommended to use a waterproof varnish for better protection.
The plaster contains resin, auxiliaries, pigment, cement, quartz sand, and water. It complies with the technical specification PN-EN 15824:2017 and is resistant to water vapor and water absorption.
A paintbrush is suitable for applying the primer and final varnish. For the concrete plaster itself, it is recommended to use a Venetian trowel. Both products can be found in our accessories category.
After applying the varnish, the plaster is resistant to moisture and dirt. For use in shower cabins, we additionally recommend applying a waterproof varnish to ensure resistance to running water.
The concrete plasters can be mixed as desired. To enhance the effect, you can use a different color for the first layer than for the second layer.
Thanks to our primer, the concrete plaster adheres to almost all surfaces. It can be applied to cardboard panels, concrete, foam concrete, gypsum, cement-lime plasters, and other surfaces, as well as surfaces made of bricks and other materials.
If you want to have a glossy surface, choose the option with a glossy varnish that you can use on its own or mix with a matte one to achieve a “satin” effect.
