Remove old blue tac.

cosmowillie53

I'm painting a wall that has old blue tac remains on it. (that sticky stuff)
It has been painted over a few times over the years I'd say but I can see it in the background.
Is there a way I can smooth it out now before I start painting . I don't want to just paint over what's already there. There must be 30 or 40 bits of it here and there.
Thanks.

Fine sand paper and filler..

No use to you now as its been painted over already but a tip:

Best thing to remove bluetac from a surface before painting is......... a bit of bluetac. Just make a ball of it and rub it across the sticky bits on the surface and voila

I'd scrape it off first, especially if the area is going to be filled either way. I'd use a sharp filling knife rather than a scraper though.

Thanks for the help so far folks.
I think this is going to be a tough job to get right.

Scrape off what you can and use a citrus based stain remover and sugar soap as recommended:

How do I remove faint stains from the walls?
Citrus based stain remover is the best. If the walls have been painted sometime ago, they can become porous which will suck the oil out of Blu Tack. In this instance, you will need to clean with Sugar Soap and generally repaint the surface.

Why does Blu Tack pull paint off the wall?
Care should be taken on painted plaster as Blu Tack's adhesive qualities may cause paint to come away from wall. When walls haven't been properly prepared prior to painting or there is insufficient paint on the plasterboard. Blu Tack will stick to the paint surface and over time the Blu Tack coupled with the weight of the item its attaching, will eventually fall off, taking paint with it because the paint hasn't sufficiently stuck to the plasterboard. Blu Tack becomes more adhesive as time goes on, so when removing it after a while, it’s a good idea to soften the edges with a citrus stain remover. Remember when removing Blu Tack, roll it off carefully never pull it off the walls.

As Dodzy says - using blue tac to remove blue tac is the best way.

Thanks for reply.
If it was new tac it would be handy but its old stuff.
