Q. Use of primers in joint sealant?

Most of the joint sealants applied in concrete joints are adhesive and recommended joint width/depth of joint sealant is from 2:1 to 1:1 as given by BS6213 and Guide to Selection of Constructional Sealants. When joint sealant is applied on top of joint filler in concrete joints, extra primers are sometimes essential since: 

(i)  Primers help to seal surface to stop chemical reaction with water;

(ii) It gives a suitable surface for adhesion of joint sealant.
