Water proofing bathroom/terrace/sump

[sk1976]

I need to start waterproofing of bathroom/terrace/sump. I read from this forum that for bathroom, Fosroc Brushbond+Nitobond BB can be used and for sump Brushbond RFX + Nitoband BBX need to be applied. For terrace, do we need to apply these chemicals separately(like in bathroom/sump) or is it enough if we provide proper sloping by adding the waterproof liquid in the cement+12mm jally+sand slurry on RCC slab.

Also do the masons apply the water proofing chemicals themselves or are there experts who do this job?.

Could you please share the process.

In my opinion these mason/mestris are unfit for this. In my case atleast
the mestri said for water proofing just mix some chemical and paint it.

For the bathroom I wanted to go for FOSROC based solution, unfortunately
I could not locate any applicator. So I finally called the Dr.Fixit helpline
and could get somebody to apply Pidifin 2K to the bathrooms.

Now for the sump I am again looking for FOSROC solution.

Yes.. Mestri are not aware of technicality of this. I and my father did it for 600sqftt.
I used Dr Fixit New coat and a recommended primer, cement colour and painted entire roof and it sticks well.

Since I have done few months back, i am not sure how effective it would be.

Hello,
I am getting water proofing done in few days.
Wanted to know how are these chemical (FOSROC Brushbond RFX + Nitoband BBX) used while executing (water proofing for sump)
Is it fixed with plastering ie cement-sand mix ?
Is it painted after doing plastering ?
