Review: Yellow or Blue. Both Are Good Picks. - I wasn't sure this generic yellow sill seal from TVM Building Products would be what I wanted, but after ordering a roll to compare against the usual DOW Blue sill seal, I am pleasantly surprised that I actually prefer it and the best part is that it is about half the price of the blue here on desertcart. I haven't compared to locally source building supply outlet prices, but at roughly $8.50 per roll at the time of this review I feel its a good price. The fluted bottom side design of the foam seal helps it to lay flat while conforming to variances in the concrete. I think it does a great job at that. If your slab has greater than 1/8' dips and sags neither product will fill that void. You may want to add a caulking product to supplement. 2 or 3 (3/8") thick lines laid down under the sill seal can fill those. When placing the seal over anchor bolts I found that a small x-slit allows it to slide down over the bolt. You can follow up with a circular round cut if you want. On windy days it may want to blow around out of alignment. A little caulking under it can help with that too. The blue and yellow seem to be made of exactly the same material. It stretches and compresses the same. I will say that the one down side to the fluted design is that it can tear easier at the thinner fluted parts. You just have to treat it a little more carefully. You can butt or miter the corners. I overlap them then cut thru both at the same time to get an exact miter. I do add caulking sealant at the joints. I come back and caulk seal the interior and exterior edges of the bottom plate to the slab later to keep insects out. Whether you go with this foam seal or a fluid applied sealant, it is a great way to transition from concrete to wood. Its alway fun to get out of the foundation stage and on to framing. Hope your project goes well. ** Update - I did find the blue stuff available at a blue big box store for $7.50 per roll and the 3.5" for $6.50 per roll. That makes it a same or slightly better value. Just wanted to update and mention this fact.

Plenty of sizable ribs ... *by D***S on June 21, 2016* No problems with this one. Plenty of sizable ribs to do the intended water seal on a typical semi-flat concrete base. --- ## 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.uk/products/148328969-5-1-2inx50ft-sill-seal-75055](https://www.desertcart.co.uk/products/148328969-5-1-2inx50ft-sill-seal-75055) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-05-24*
