I have a Degraded Polyethylene Terephthalate (DPET) to mix with the bitumen, therefore I want to use this mixture for concrete coating for waterproofing. Could anybody have the easy method to have a high quality of coating and homogenous?
Clean the surface of the top layer and sand blasting it mildly to remove the weak top layer. Then blow the cleaned surface with air and apply the bitumen to it in two perpendicular directions to ensure penetration of the bitumen.
Dear
The proper coating method is highly dependent on the viscosity of your bitumen-polyethylene coating material, i strongly agree with Prof. Altaan on the procedure described, but the viscosity of the coating material should be reduced by solvent (mainly kerosene, white sprite or naphtha) so that you can control the homogeneity of the coat if you apply it either manually or by blowing under pressure.

Thanks a lot Professor Saad Altaan
So many thanks Professor Saad Sarsam
Could you tell me if there is an advice or technique to have a homogeneous coating layer (thickness)?
I have to make a comparison of coating with various% of DIET.
BEST REGARDS
Dear
If the proposed application technique of your coating material is manual or by blowing or spraying, you can fix a specified weight of the material per square meter of the area to be coated. This may be conducted by trial application with variable weight of the coating material on fixed area and check the suitability of the thickness obtained for damp proofing or for prevention of deleterious materials form reaching the concrete. A laboratory testing of such application will be useful before a decision is taken for field application.
