securing kitchen floor cupboards

[shezzar]

hi guys,
i am in the process of fitting a new kitchen, and have found out that the walls have been plastered using a dot and dab technique.
I am now trying to secure the cupboards to the wall, but as the walls have been dotted and dabbed for the plastering, the (normal) screws dont stick to it.
Has any one got any ideas of how i would be able to secure the cupboards?

If these cupboards are floor cupboards, as your title suggests, you don't really need to fix them. If your also fitting up wall cupboards, these can be set on a 2"x1" bearer piece. Fixed to the wall at the cupboards intended height, the fixings should go in wherever there is a dab behind the plasterboard. These bearer pieces can either be painted out with the colour of the wall (or close) or if they become hidden generally (under and to the back of the cupboards) and a light pelmet fitted, they are invisible. The cupboards are now bearing on the pieces and can be fixed in similar fashion at the top. In both cases the cupboards can be screwed through from into the the bearing pieces...pinenot

Fix as usual but drill 20mm deeper and push plugs all the way home then use screws 20mm longer.

For the wall cabinets, when you get to them, I strongly recommend hanging rail. It has lots of screw holes so you can fix at convenient points, not necessarily in the same place as the cabinet hanging brackets, and you can move the cabs along the rail if you want.

yyy to drilling through the plasterboard and void into the wall behind, using long screws and plugs.

thanks guys,
Just to make sure that i am getting the right end of the stick, so to speak.
Basically, i just need to put some bigger screws through, What colour wall plugs would you suggest, the brown or red ones?
