Ready to Paint House:
Houses that are ready to paint have had their wall plasters completed (especially the bands between the plates of BA13). The qualifier "ready to paint" implies that all you have to do is get your rollers out and go ... make no mistake! There is so much to be done!
The plasterwork isn't done yet. You'll need to brush all of the excess plaster off of your substrate. You also run the risk of running out of plaster. As a result, you'll have to make a final pass. You'll have to sand, then reload, then sand, then reload each time ... It can seem endless to a non-professional ... We still use too much filler and have to sand 90% of it.
This is usually the type of work that necessitates prior experience as well as a "helping hand." As an electrician (I hope no electrician reads this), I find it much easier to improvise than as a plaster. You've been warned!
House that is Ready to be Decorated:
This is the standard of finish Lion Hdb suggest if you can afford it. The first undercoat of paint has been applied, and the coating has been completed. Just a few plaster touch-ups are left to be done at this stage. Even for a novice, it's not too bad.
If you have to move into your home quickly for whatever reason, it will be clean and livable. The consequence of only one undercoat, of course, is especially dreadful. The underlay's sole aim is to prepare the support and is not intended to be decorative.
