Hi and welcome

No more ply say that you can fix 6mm boards on existing surfaces with there adhesive

Thanks for that - I'll acquire some of their adhesive but they also suggest that some mechanical fixing - i.e. plugs/screws- may also be necessary but don't elaborate any further. I'd like to do a belt and braces job so wish to use mechanical fixings as well as adhesive - can you recommend a screw/plug size and centres for fixing?
