Years of smoke leave a resin residue on ceilings and walls that ordinary emulsion simply cannot cover. Paint over it directly and the yellow-brown tinge reappears within days, along with a lingering smell that a coat of white paint alone does nothing to address.
No — it typically bleeds straight back through even several coats of standard emulsion without a dedicated stain-blocking sealer first.
Yes, it removes surface residue that would otherwise sit under the sealer, though it does not replace the sealer itself.
Sealing helps significantly, but very heavily affected properties may need additional cleaning and ventilation for the best result.
The staining is a chemical residue, not just a colour on the surface, and water-based paint reactivates and pulls it upward as it dries. This is one of the more predictable coating failures in decorating, and it catches out anyone hoping a couple of extra coats will solve it.
A sugar soap wash removes the worst of the surface residue and loose particulate, which helps the sealer bond properly, but washing alone does not stop the chemical bleed-through on its own. Both steps matter, in the right order.
A stain-blocking sealer also helps trap residual odour that has worked its way into porous surfaces, though very heavily affected properties sometimes benefit from ventilation and further cleaning alongside the redecoration for the best result.
Tell us how affected the property is and we will confirm the washing and sealing sequence needed.
Nicotine staining needs washing down and a dedicated sealer, since ordinary emulsion alone lets it bleed straight back through.
