Do I need to apply more putty to the wall?

  I wonder do I still have to apply one more layer onto the putty or I can simply sand it and paint on it.

Hello @Hayaimi 

Welcome to the Bunnings Workshop community. It's sensational to have you join us, and thanks for sharing your question about your wall repair project.

You're doing very well, but I suggest adding more putty to the area that has a small depression in it. My best advice is to add only enough filler so that it is level with the wall. In this manner you won't have to sand off too much filler. Make sure to give the filler enough time to dry off and cure before you start sanding. 

If you need further assistance, please let me know.

Thanks for your advice! 
I’ve actually covered it with primer coat. Does it matter to level it with the wall. Does it matter once I gently sand it off? (I have copied your advice using primer instead of putty)

Hi @Hayaimi 

Now that you have applied the filler, just wait for it to dry off and cure. Once it is hard, I suggest using Rocket Sanding Sponge Kit to level the filler on the wall. Make sure to wipe off all the sanding dust before you start painting the wall.

If you need further assistance, please let us know.

Thank you so much for the information. 
Also, the featured filler is comple  dried out can I restore it for use?

Hello @Hayaimi 

I'm sorry but once the filler is dry it can't be recovered. The filler must not be left open for long periods of time as it will dry up and become hard. If you look closely at the print at front it says "Rapid 30" which means that the filler will dry up and become hard in 30 minutes once it is used.

Perhaps the bottom is still usable, but you'll need to remove the top portion to see if the bottom is still soft.

If you need further assistance, please let us know.

 I would like to know how can I quickly ease the slightly swollen parts in this picture, I tried 120 grits sand paper and it didn’t work. 
also I can’t sand too much as it will make the metal drywall patch visible.

Hi @Hayaimi,

The plaster needs to be applied over a larger area to create a less abrupt mound on your wall. 

At this point, I would suggest using a hand sander and sanding your work right back to almost the metal patch. You can then start adding thin skim coats of plaster. Take a wider-bladed plasterer trowel and start applying the plaster over a 30cm x 30cm section. Do long strokes horizontally and then vertically, ensuring even distribution. Once dry, you can then sand the area to a flat surface.

Here's a helpful guide: How to fix a hole in the wall.

Please let me know if you have any questions.

Hello @Hayaimi how quickly depends on what tools you already have... an orbital or random sander will make short work of levelling plaster filler BUT it will make a substantial dusty mess, drywall sanders will work even faster and generally are paired with powerful extraction systems/vacuums. 

I use a combination of hand sander like this

Along with an ancient 1/2 sheet sander like this

Recessing patches provides room to fill up to an even surface, when not possible filling over a wider area helps mask the repair, remember with plaster the old adage applies, use less - sand less 👍
