painted over?
You can with oil based paints, but not water based.

Never use silicone to fix cracks - use decorators caulk. Same idea, but
acrylic, and takes all paints well.


Thanks Natural philosopher do you have a link to where I could buy it,
so I know what Im getting??


Good heavens..Any decent builders merchants and PROBABLY B&Q..

You need a sealant gun thing as well.

Welly it in and use a wet sponge or finger to smooth it out.

You can put emulsion on it after half an hour or so..it takes a day or
two to set completely.

It is a LOT smoother than plaster so it is a shade noticeable..but if
dobbed with a sponge it might pick up a nice texture..


As far a I can tell its simply arcylic primer 'done thick'.

Somewhat akin to very sticky emulsion paint, haha.

There's probably a bit of plasticiser in it as well to make it
flexible..it can take a LITTLE movement without cracking.

Acrylic Frame Sealant is a similar beast, but more expensive and
probably has more plasticiser in.

Unlike the silicones, which are truly great till you need to paint em (I
don't believe ANY paint sticks to silicone) acrylics are paintable even
when still soft..with water based paints anyway: Oil I have never tried.

My standard decorating algorithm is first clear up the loose stuff, then
make good major gashes with filler, then sand everything down, then use
caulk to fill cracks between walls and ceilings and woodwork and
plaster, then paint away..wit Farrow and Ball, cots they have ten times
the pigment anyone else does.

End results are good.





Thanks
