Regular emulsion can cause wallpaper to bubble and blister, but not Zinsser. It's formulated to seal the paper and protect it from the paint's moisture.
Once dry, this one-coat solution creates a new surface that's easy to paint. This high-hiding primer not only obliterates wallpaper print, but also acts as a stain blocker. Seeping stains from smoke and damp residue are easily covered, with no worry of them reappearing. Coverage of up to 8m² per litre. Touch-dry in just 2-4 hours. Full cure in just 4 hours. Easy to apply by brush or roller. Can be used under any coloured emulsion. Supplied in a 2.5L tin - total coverage of up to 20m². Any questions, feel free to ask.
