But if you scour the surface first, you might be lucky. **Q: I have painted skirting boards were knots havent been sealed will this work to stop bleeding from knots coming back through** A: Not super impressed with this when trying to stop “greasy” leaking from decorator’s caulking. If it was me, I’d use original knotting compound which always works. **Q: Do you have to do it over the entire wall or can it just be the patches? I was to repaint the whole wall in grey.** A: As long as the stain is dry. You can indeed touch up the affected areas. No need to do the whole wall. **Q: How good is this over black mould in a bathroom? Tried several things and nothing works.** A: Use a brand called HG …. Mould spray works wonders, black mould literally disappeared after 30 minutes ## Frequently Bought Together - Rustins Stain Blocker & Multi-Surface Primer 250ml - Pro Grade, Paint Brushes, 5-Piece, Paint Brush Set: Flat & Angle Brushes for Latex and Oil Paints, Stains, Interior & Exterior Home Improvement --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.za/products/48112305-rustins-stain-blocker-and-multi-surface-primer-250ml-versatile-all](https://www.desertcart.co.za/products/48112305-rustins-stain-blocker-and-multi-surface-primer-250ml-versatile-all) --- *Product available on Desertcart South Africa* *Store origin: ZA* *Last updated: 2026-11-09*
