can I use wall repair tape to fix hairline crack?

[daxu]

Hi,
My house is from 1930s and I am thinking of selling it.

As it is a quite old house, there are some hairline cracks on the wall. I asked around and apparently for old houses like this, it is normal to have some movements and as a result, hairline crack will show up.

I found this Wall Repair Tape from screwfix (http://www.screwfix.com/p/wall-repair-tape-white-50mm-x-25m/78232). This seems to be a really easy way to patch the hairlines (as the hairlines are not getting larger).

Am wondering can I just put the tape there and then paint, or I need to apply some adhesive compound and then paint?

many thanks

You can't just paint straight over that and expect it to look 'invisible'. You would need to feather the edges out with some filler to get it to a decent standard. Even then, if you paint over it with any finish that has a slight sheen to it you will still see where you've put it.
Personally I would fill the cracks, sand smooth and hang lining paper to affected walls.

Hi Deccy,

How about this product?

I generally just dig out the crack, apply with filler (leading a bit proud), then sand flush once fully dry. Once the wall is painted, it should be invisible.
