hi guys,

gyproc(plasterboard)good f
lat surface to work on,easy to work with but ruined when it gets wet,so hence tanking is recommended in wet areas.

plywood...easy to work with,used mainly on floors..swells if excessive amounts of water is ingressed due to burst pipe etc.

there you go thats a couple for starters.

There are loads of substrates used

The ones I deal with most are

Concrete - powerfloated, brush finished, trowel finished, float finished
Sand Cement Screed (including modified screeds) - Usually trowel finished, occasionally brush or wood or steel float finished
Flowing screed - either cement based or calcium sulphate based (anhydrite or alpha hemi hydrate)
Thin Screed - e.g. levelling compounds which can be cement based or gypsum based usually - normally need to be flexible for tiling
Asphalt toppings

Two coat plaster, float and set, limited to 20kg
Render work, 40kg m2 good but depending on the quality of sand and plasterer
