Wet blasting/sandblasting

Wet blasting developed out of sandblasting, but it has one obvious advantage in that it does not create dust. The method is very effective in removing old surface finishing on masonry and steel.

The KTV Group also uses vacuum blasting methods so we can recover any sand that we use. This makes it theoretically possible to sandblast indoors or in areas where dust or water could cause problems.

We offer:
– Removal of surface treatment on steel/masonry
– Processing substrates before coating
– Removal of mould lubricant on recently poured walls.
– Rust blasting.

Sand washing

This method is a combination of high pressure/water jetting and sandblasting. We use machines at 400-500 bar with special nozzles that make sand injection possible

– Removal of surface treatments
– Removal of mould lubricant
– Processing surfaces for adhesion

Soda/chalk washing

Here we use high-pressure washers at 300-500 bar with special nozzles for injecting soda. This method is used for cleaning special surfaces like mineralite stucco, copper and other surfaces that are sensitive to chemicals, or where sand washing/blasting would be too abrasive.

This method is used especially on older masonry facades where caution must be exercised.

Used to:
– Clean facades.
– Clean sculptures/ornaments


We work closely with the market’s most trusted paint manufacturers, so we can always offer our customers the best solutions.

Our property division has years of experience in the rehabilitation of apartment buildings, facades, townhouses, stairwells etc. In recent years we have completed major works at several housing cooperatives and joint ownership associations in Bergen. We are happy to assist our housing cooperative or joint ownership association customers with advice, and information for their residents.

The KTV Group also offers 10 to 20-year maintenance agreements for exterior facade care.
