Morning all,

I stripped our old glypta (sp?) wallpaper off week before last and completed the whole sand, fill, sand, wipe down, undercoat, top coats etc, however on one wall I have multiple of these 'drips' as below.

The wall clearly used to have picture rails up before being taken down when original owner put the heavy set paper on the walls, however I have since put the picture rails up with rawl plugs and screws only, no 'no more nails' etc so it's not my drips.

No matter how many layers or how thick the paint goes on the wall, it just 'shines' through in this drip form, so firstly, what is it? (Possibly some glue used on pic rails a long time ago/glue from the paper?!)

And secondly, what can I do about it? Can I seal it with something that will then allow me to emulsion over it?

Any help much appreciated :cool:

can't tell from the picture what the stains are , but i would give them a bit of a sand down and then treat with something like this http://www.zinsseruk.com/product/bulls-eye-1-2-3/
however if you have some solvent based undercoat then you could try that first

Thanks NIck. I don't have a clue what they are either?!

Fortunately there's a stockist of the Zinsser just over the road from me. In the meantime, I'll try some solvent based undercoat. Would a standard wood/metal primer/undercoat suit or not in this instance?

as long as it's solvent based , not water based
