I have used this on old floorboards, followed by Little Greene Floor oil based undercoat and finished off with Little Greene Floorpaint. This was done three and a half years ago and it still looks brand new. **Q: Is this the shelac 4 base version** A: Not sure. It doesn't have a shiny finish, it's a Matt finish. Maybe you could describe it as very slightly 'egg shell'. It's a very good product and covered sky blue plaster board in one coat with ease. It's also much thinner than normal paint (surprisingly) so, if you buy it and intend to apply it with a roller brush, be prepared for some spatter. **Q: Is this good for sealing nictotine smells?** A: I have a rented property which had a very stained ceiling in the lounge. I sugar soap washed and then painted, it is very thick so you use more than you think. After 6 months there is no sign of the stain or smell. Very happy with the product **Q: Can zinnser cover stain be painted over linseed oil putty window caulk? can cover stain then be painted over with water-based paint?** A: Yes ## Customer Reviews ### ⭐⭐⭐⭐⭐ Excellent product *by on Reviewed in the United Kingdom 1 March 2026* Excellent product. A name I know and trust. Great quality. Does the job. Covered stains and dries well. Would recommend. ### ⭐⭐⭐⭐⭐ One of the best primers *by on Reviewed in the United Kingdom 7 July 2026* Very effective ### ⭐⭐⭐⭐ Does the job *by on Reviewed in the United Kingdom 23 September 2020* Certainly covers up various stains. Used it on a water stain on the kitchen ceiling. Couple of coats just on the stain did the job & I didn't have to do the whole ceiling. Also used it to cover some knots in a wardrobe, which it also did well.Main point of purchase was as an undercoat for a garage door. Pretty thick so takes some good elbow grease to cover a large area. However, the subsequent coat of standard gloss then goes on easily.One note of caution. It stinks for ages! If using it inside, best do so when you can leave loads of windows open for a whole day (or more).Overall, good stuff though. ## Frequently Bought Together - Zinsser Cover Stain 1 Litre - Harris Essentials Walls & Ceilings Paint Brush Set | Pack of 5 | 0.5", 1", 1.5", 2", Grey - Harris Seriously Good Walls & Ceilings Twin Medium Pile Paint Roller Set with Tray & Frame | 9" --- ## 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.us/products/48192215-zinsser-cover-stain-1-litre-premium-exterior-wood-sealer-high](https://www.desertcart.us/products/48192215-zinsser-cover-stain-1-litre-premium-exterior-wood-sealer-high) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-08-26*
