I am doing a lot of DIY at the minute. I have lost my DIY mate ( parent ...... yes, I have had another bereavement since last year, just before Christmas, please don't go there) , so I am on my own. OH hates DIY as well as gardening.
So, I have paper and I have stripped walls in dining room ( this is because now my walls are not suffering condensation there I can try and get it sorted) . I have cleaned them down and even put a coat of fungicide on the affected bits in there.
I have some old ( about three or four years) wallpaper paste. Its unopened. Completely sealed packets. Is it usable? I cant see a use by date on it. Doing that job this weekend. Thanks.
