Hi, I am from Goa. One of our building having Expansion joint of 30mm width. Is this suitable ?

[@juliafun82]

But can u tell me something, we manufacture and assemble Precast RCC buildings. So 2 questions: 1. This treatment has to be done on both sides of the panel joint? 2. What special putty/primer/paint is to be used for finishing over the joint so that joint is not visible?

[@swathytradingcorporation3679]

Dear Ashish, Yes both sides filling required, Primer required if possible to spray

Hi, I'm working with WBSEDCL in the capacity of assistant engineer. I'm looking for a working method for applying flexible sealant into vertical expansion joints of our generation unit housing building. If you could kindly help me with the same I'll be grateful.

Sir, what is the purpose of Primer on the joint

[@aquatechat1586]

too much of sealant wastage on the masking tape, which will add extra cost to the contractor, how do we consider the wastage in % ?.

[@genecarden780]

Don’t over shoot the joint. There should be very little to no sealant on the tape. They are not very skilled. But their methods are right except you should use a rounded putty knife for a concave surface and should NEVER USE SOAPY WATER.
