Any Plasterers out there ?

[Slug_killer]

I want to replace a section of my ceiling plaster board.

I went to Wicks today and their boards were marked as 'wall board' or 'baseboard'.

Sooooo whats the difference ?

The assistant was quite useless, didn't even know you could use plaster board on ceilings !

Baseboard is a term unique to wickes they are both the same thing just different size sheets, either would be suitable for replacing a ceiling.
Wickes wallboard = 1800 x 900 x 9.5mm.
Wickes baseboard = 1220 x 900 x 9.5mm.

Found these and they all consistently say that baseboard is for plastering onto and wallboard can be either plastered or decorated.  I'm not a plasterer though!

Knauf Wallboard
Knauf Wallboard is plasterboard with an ivory paper face ideally suited to receive a
plaster finish or for direct decoration.

Knauf Baseboard
Knauf Baseboard is plasterboard with two grey paper faces to be used as a base for
plastering.

8. The three main types of plasterboard are baseboard, lath and wallboard,
each of which is produced in various thicknesses, widths and lengths. Baseboard
and lath are principally used on ceilings nailed to joists and finished with one
or two coats of plaster. Wallboard is used both on walls and on ceilings and may
be plastered (on the grey side) or decorated direct (on the cream side).

One of the reasons for replacing parts of the kitchen ceiling is to change the lighting.

Currently I have 2, 4ft florescent bulbs each is  36w.

I would like something a bit more fashionable, but can't workout how many smaller bulbs I would require.

For normal household bulbs, the 100w has been replaced with the 20w low energy ones, so would that mean I need an equivalent of 36*2*100/20 = 360w  ???

Halogens appear to be the latest fashionable thang, but when I stood near the lighting counter in Wicks, the heat was so intense, I thought I was in a tanning studio   :o

4ft tubes are usually 80w, I haven't seen any 36w.

Halogen lamps should always have a filter in front of them, they tend output a high ultra voilet light (skin cancer) so long periods of exposure could be risky.

If you scroll down to point 2 in this link, it gives a formula for calculating the light needed for different rooms.

I think though that the number and position of the lights is equally as important as the wattage.
