I've finally taken the plunge to redecorate the downstairs loo and utility space beside it, as the wall paper was going mouldy from the time the washing machine leaked and the bits of trim the last owners had glued on 3 walls in random shapes were driving me mad. So I rip off wall paper and trim to find lining paper stuck around the trim onto (unsealed) plasterboard underneath, a variety of hardened glues and gloss paint from where the trim had been painted prior to applying the textured wall paper. In the past I've steamed off wallpaper, but I think if I try that here I could lose the plasterboard surface, as it does seem to be a bit delicate.
If I remove all the paper, sand down the hard bits of paint, plaster and glue, fill in any holes and then seal what is left with this 3 in 1 basecoat/sealer or similar what are my chances of then having a surface which will be flat enough to paint, and not need to repaper it? As the utility area doesn't have any bits of twig trim stuck on the walls, I've decided to seal the wallpaper with the basecoat and then paint over that, for easy maintenance.
I'm finding it hard to remove the layers of paper, and at one stage was considering just peeling off the top layer of texture and then sealing over the top of that, but have discovered that just a bit of water sprayed over it and rubbing with fingertips helps a lot. Does anyone have any advice on how to make this job any quicker and easier?
