fixing hardibacker 250 to a highly glossed floor

[doug boardley]

I was thinking more along the lines of primer soaking into t and g, :shy:

It states on the HB site that the adhesive is just to take up voids in the substrate,,

yes thats right adh is mainly to fill hollows (cuped floorboards ect) it sticks to backer board and screws do the holding thats why screws are better than nails

I actually forgot to screw one to the floor but used sbr with the addy and it stuck, I was advised from a shop to nail and adhesive under the hardie then remove nails:yikes:

wow with advice like that you don't need enemies fingers crossed for you

its a bit like plaster boarding a ceiling years back they said just use stab (adh) and nails to be removed when dry
after many failures they now recommend screwing as well

just to add you nail through a small scrap piece of plasterboard into new ceiling when dry remove if you understand/////
