I read in another post that sikaflex would be good for sealing step rubbers.
I just welded/painted new steps and have new rubbers to fit.
Which would be the best sikaflex to use? I see there are several. 512, 521, 221 amongst others.

Sika EBT is fantastic for this application and you can get it over the counter from builders merchants and possibly screw fix.
