Interior Wall Putty | Smooth Finish Wall Leveling Compound for Surface Preparation & Decoration

 NZ-100 features high bonding strength to eliminate hollow peeling risks on concrete, plaster and gypsum substrates. Its rigid cured layer blocks tiny substrate cracks, while reliable 96h water resistance stops alkali blooming and wall discoloration in humid indoor spaces. Superfine powder delivers silky troweling, easy sanding into mirror-smooth base that maximizes the flatness of latex paint, wallpaper and decorative wall coverings.

Non-toxic, odorless zero-formula meets strict indoor environmental standards for homes, offices and hotels. High water retention delivers extended working window, avoiding premature drying during large-area construction. Follow thin multi-coat application principle to prevent inner-dry surface cracks; standardized 3:1 water mixing ratio ensures consistent texture without random glue or cement adulteration.

ProtectionComplete construction workflow: clear loose residue → apply interface agent → lay anti-crack mesh → two+ thin putty coats → full 24–48h curing → sand smooth → seal alkali-resistant primer. Substrate must be cured ≥14 days for new plaster walls, with moisture below 10% and pH＜10 before application. Low later maintenance cost; one-time qualified putty base keeps wall decoration intact for years without blistering or fading.
