June 22, 2021 | w.gigliOur sandblasting company Hänni AG specializes in the cleaning and treatment of a wide variety of surfaces. You have the surface, we have the solution!
We can draw on 30 years of experience in the field of sandblasting.
Sandblasting, our all-rounder!
With the sandblasting method, we are able to process all substrates. With the right choice of blasting material, nozzle and air pressure, everything from heavy abrasion in the metal sector to the finest blasting work on listed buildings is possible. With our wide range of different blasting media, we always have the right material to hand. We use melting chamber slag, broken glass in various grain sizes, nutshell granulate (walnut), maize meal and garnet sand.
In our company, sandblasting is very frequently used on wooden surfaces. We remove all coatings from facades and interiors. We also very often treat untreated woodwork to remove the traces of time. Wood blasting is extremely demanding. Thanks to our extensive experience, the treatment of wood is one of our specialties.
In the area of corrosion protection, the surfaces of various structures are perfectly prepared for the application of rust-protective coatings using sandblasting. The SA 2.5 degree of purity is easily achieved with sandblasting. Definition SA 2.5: The surface is defined as being free of any oil, grease, dirt, scale, rust/corrosion, oxides, paint and other foreign bodies.Woodwork:Facade areas, roof trusses, wooden structures, interior wooden cladding, sliding floors, ceilings, stairs, fire restoration, furniture, window shutters, etc.
Metal surface:
Iron construction, bridges, preparatory work for tank overhauls, canopies, railings, grilles, body parts, rims, motorcycle, moped and bicycle frames, radiators, etc.
Concrete:
All concrete surfaces
(slurry blasting also possible)
Slurry blasting
Slurry blasting is a combination of compressed air, blasting material and water. The added water binds the dust and makes this blasting method virtually dust-free.
We use slurry blasting to roughen concrete surfaces. The finishing of concrete is becoming increasingly popular.
We use slurry blasting to remove plastic-bound coatings that are harmful to the substance from mineral plaster. This work step is essential as preparatory work in order to achieve a mineral structure.
We remove stubborn graffiti that cannot be removed with water jets using the slurry blasting method.Roughening of smooth surfaces
such as concrete, stairs, landings, etc.
Removal of graffiti that cannot be removed with water jets
Removal of harmful plastic-bonded coatings on mineral plaster
Removal of all coatings and soiling on masonry, concrete and artificial stone
Water blasting
Water jetting is a very clean way of cleaning. Our modern jetting machine can be supplemented with various devices. The skater is used for cleaning large areas of outdoor floors. The Skater is a machine equipped with flat nozzles. The sprayed-on water is extracted with a vacuum nozzle and transported away via a hose.
For façade surfaces, we use the Skater's little brother, the Twister. This device works with the same technology and is easy to carry thanks to its low weight.We also use lances for all surfaces. These can be equipped with flat nozzles and dirt cutters. We use the latter to remove the buoyancy from the concrete (without aesthetic requirements).

Removal of graffiti
Concrete floors
Industrial floors
Exterior surfaces (interlocking paving stones)
Sports fields
Parking lots, parking garages, roofs
Dry ice blasting
This method is our most modern way of blasting. The area of application of the dry ice blasting method is very limited due to low abrasion.
The surface is only slightly altered during dry ice blasting. This method is therefore used more for cleaning purposes.
Dry ice blasting is very suitable for removing protective coatings (Tektil) from the underbody of vehicles. Dry ice blasting is also the ideal method for cleaning delicate parts, such as engines, where no blasting material is allowed to get inside. In the facade area, we remove stubborn ivy roots from plaster and woodwork with dry ice. Weathered glazes can also be removed with dry ice.
Graffiti removal on historic buildings
Removal of heavily weathered glazes
Cleaning of natural stone
Removal of ivy roots on plaster
Removal of oil and dirt from engines

Sandblasting cabin
We process surfaces of various materials in the sandblasting cabin. Our blasting cabin is suitable for all objects up to 5m in length.
The processing of furniture is very popular.
Renewing old furniture
Garden furniture made of wood and metal
Windows & doors
Radiators
Rims made from steel and aluminum
Car, motorcycle and moped parts
