Product description indicates it may be used externally (with limitations: over-paint with oil based paint and do not use on surfaces 'regularly under water!). I have not personably tried using it outside. Think I would use a product specifically designed for outside.

Tetrion

Q: Hi, is this product used for skimming entire walls/Ceilings?

The outer bag contains a number of smaller bags for small mixes. This is a jointing compound for applying and covering jointing tape particularly on dry lining joints, although I have successfully repaired ceiling cracks using this and jointing tape. I’m only a home DIYer and nowhere near professional, but I’d guess if it covers joints it can cover a smooth ceiling, but you’re going to be opening quite a few bags to do a ceiling.

Q: How big is this in kg's

All I can tell you from the information on the packet its 500 g

Q: What colour is this product. Thank you

Very pale grey, or perhaps more an off-white.
