Primers in Rohini, Delhi

Almost always. On new plaster, after wall putty, or over old painted surfaces with stains — a good primer extends paint life, improves shade fidelity, and prevents the topcoat from being absorbed unevenly.

SmartCare Damp Sheath Interior Primer is the most-asked-for product for damp-affected interior walls. Sparc Interior Primer is a budget alternative. Either way, fix the moisture source first — primer is not a substitute for waterproofing.

No. Wall primer is alkali-resistant and tuned for cement plaster surfaces. Wood primer seals porous timber and locks resin. Always match the primer to the substrate or the topcoat will fail prematurely.

For new plaster, two coats of primer is standard practice. For repainting over a sound existing finish, one coat is usually enough. Adjust based on surface absorbency.

For best results, match systems — water-based primer with water-based emulsion, oil-based primer with enamel. Cross-compatible products exist but always check the technical datasheet first.
