Recommendation: Green chipboard

[martifee]

Hi Folks,
This is my first thread, bar my introduction. I've a job in a new build house where the floors are green chipboard. I've tiled onto this before using hardie backer and that's what I plan to do again. Just wondering what you guys beleive is the best stuff to use to prime the chipboard. Last time I used PCI primer G but it beads up a bit on green chipboard.
What do you guys do? Your thoughts are appreciated.
Cheers Martin

Just wipe over with a damp sponge to remove surface dust and then over board with hardi... you will find acrylic primer just beads as you say but if you think a primer is required then use SBR..
