Usage

Sikagard®-1812 is used to provide a heavy duty protective, waterresistant and flexible coating. Widely used in the sewerage and waste water industry as well as other aggressive immersion conditions on cementitious and metal substrates. Uses include the lining of tanks, pipes and ducting, coating of concrete, asbestos cement, pipes and nonferrous metals. 
Sikagard®-1812 is particularly suitable for use in sewerage work applications and in offshore or marine environments. Sikagard®-1812 may only be used by experienced professionals.

Application steps

SUBSTRATE PREPARATION

Surfaces must be clean and dry.  Use suitable methods to remove dirt, dust, oil and all other forms of contamination that could interfere with the adhesion of the coating. 

 

Concrete

Concrete should be sound and sufficiently dry to accept Sikagard®-1812. Mechanically surface profiling is the method of surface preparation. Mechanically profile the surface to CSP3 as described by the International Concrete Repair Institute. Voids and pinholes must be repaired. 

APPLICATION

Sikagard®-1812 may be applied by airless spray, brush or roller.  Please refer to our latest Method Statement for detailed application instructions. 

CLEANING OF EQUIPMENT

Use a suitable thinner (Xylene / MEK / Acetone) in case of spillage, absorb and dispose of in accordance with local applicable regulations.
