How to Cover Nicotine Stains on Walls UK: Stain Blocking Primer
Complete Guide to Covering Nicotine Stains on Walls in the UK
Nicotine stains are one of the most challenging and common problems facing UK landlords, property sellers, and homeowners dealing with properties where smoking has occurred. The yellow-brown discolouration, sticky residue, and persistent odour make nicotine staining particularly difficult to cover, with conventional paint failing repeatedly as the stains bleed through within hours. For anyone preparing a rental property for new tenants, selling a house, or simply wanting to refresh a room after years of smoking, understanding how to cover nicotine stains permanently is essential. The wrong approach means wasted money, time, and the frustration of seeing yellow stains reappear through fresh paint.
This comprehensive guide explains everything you need to know about covering nicotine stains on walls, from understanding why they're so difficult to cover and why regular paint fails, to using the best stain blocking primer for permanent results.
