Sika Primer 210 Tin 250 ml Pretreatment

I found this to be quite useful. It's like a varnish in its appearance so the user needs to be careful not to spread it past the working area to prevent clean-up problems. The amount of fluid in the bottle goes a long way, so I've found that there's a lot left over, but it doesn't store too well and goes off over time, so, it's something to bear in mind when planning how to best use it. I've bought it again and would recommend it.
