Procedure for Laying Acid Resistant Flooring
The concrete floor needs to be free from any surface cracks, and the Ievelling needs to  
be plain.
STAGE 1st: In the stage 1st of work is clean in g of the platform, to remove any loose  
particles and to give it a rough fi n is h, for application of acid proof primer.
STAGE 2nd: After the concrete surface is inspected and found to be free from cracks and  
defects of any kind, Primers are applied as indicated above, either with b rush or with  
spray. The primed surface is then allowed to dry until tack free, which under norm and  
conditions, will take approximately 6 to 8 hours depending upon the temperature at the  
site of application.
STAGE 3rd: Acid proof bitumen mastic, being a solid mass shouId be broken into fairly  
small pieces. It should be put into a tar boiler and heated upto a temperature of 1 25° C -  
1 50° C. The molten mass is then applied by pouring and smoothening ea layer by  
trowelling on the horizontal surfaces. However, for vertica, I concrete or MS surface,  
application is carried out by a square trowel. It is applied in 2 or 3 different coats, each  
coat approximately 4 mm thick.
Stage 4th: Acid Proof Mortar is prepared by mixing one part by weight of the acid proof  
solution with three parts by weight of acid proof powder. It is then applied by buttering  
the edges of acid proof bricks/tiles and by placing them in a position, under squeezing  
action maintaining a g a p of 3 -5 mm between bricks/tiles. Acid proof mortar should be  
laid in a manner that it forms a bed of 6 mm between the bricks and the mastic bed.
STAGE 5th: The last stage is filling gaps between bricks/tiles by appointing/ grouting  
material. F or better resistivity to the acid being stored, the g aps in between must be  
filled with CNSL, Furan, or Epoxy.
