Anyone know the difference between TigerBrand's 'Grey Skim Coat' Vs. 'Loft Wall' (think the latter is newer)? Are they for outside/ exterior walls as well as inside?? Thanks.

I recognise the grey skim as one of the basic powdered skim coats used to create smooth fine finish on rendered walls.

Loft Wall must be some kind of two pack poly mix used to create a fashionable finish they have named loft style.
