It is very easy to use and does the job Review: Good quality and price - This was the second order for the felt seal in order to complete the sealing on my shed roof. Whilst the quality and finish of the product was good there was a difference in the size of the tins (even though they both stated 500 ml). In addition the sealant in one tin was considerably a darker colour than the other when applied, so even though the job is completed I may have to order yet another tin so that both sides of the shed roof are the same shade. As a result I have deducted a star for the potential cost and extra work to have both sides of the roof looking the same. ## Features - Flammable liquid and vapour. - May cause drowsiness or dizziness. - May cause respiratory irritation. - Toxic to aquatic life with long lasting effects. - Waterproof Seal: This felt sealant is your solution for leaks or cracks.

It is very easy to use and does the job ### ⭐⭐⭐⭐ Good quality and price *by A***R on 28 April 2026* This was the second order for the felt seal in order to complete the sealing on my shed roof. Whilst the quality and finish of the product was good there was a difference in the size of the tins (even though they both stated 500 ml). In addition the sealant in one tin was considerably a darker colour than the other when applied, so even though the job is completed I may have to order yet another tin so that both sides of the shed roof are the same shade. As a result I have deducted a star for the potential cost and extra work to have both sides of the roof looking the same. ### ⭐⭐⭐⭐⭐ Quick and easy felt sealer *by K***Y on 5 January 2025* I had developed a leak along the join in my shed roof where the clout nails hold the edge at the overlap. Rather than redoing the whole roof again as it had only been done six months prior I decided to try a sealer. It has been applied now for about six months and we have had some pretty horrendous wind and rain during this time but there is absolutely no sign of any leakage in the area of the joint anymore. Simple to apply with just a brush straight into the felt and job done. Definitely does what it says on the tin. First class product imo. --- ## 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.tn/products/216094877-polar-felt-seal-waterproof-roof-sealant-500ml-grey](https://www.desertcart.tn/products/216094877-polar-felt-seal-waterproof-roof-sealant-500ml-grey) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-08-18*
