If you want to create flexible seals to hold out water, this is the stuff you need. Using it to seal 10mil poly to an old tile floor before we put new flooring over-top! Also used for waterproofing exterior door openings! 👍 ### ⭐⭐⭐⭐⭐ Just what I needed *by K***S on August 5, 2024* Very happy with my purchase, the shipping was quick and got what I ordered. ### ⭐⭐⭐⭐⭐ It doesn't get hard and brittle *by U***N on September 10, 2020* I've used Sikaflex before to seal along different areas (house brick to driveway, expansion joints in patio cement) and it works well. As with any product that is coming out of a tube, it can be messy. I laid down duct tape as a guide and this made for a pretty good looking job. One final suggestion is to thoroughly clean (wire brush) the areas that the product is going to contact. ## Frequently Bought Together - Sikaflex 1A Polyurethane Premium Grade High Performance Elastomeric Sealant, 10.3 fl oz Capacity, Black, 12 Tubes - Sikaflex 1A Polyurethane Premium Grade High Performance Elastomeric Sealant, 10.3 fl oz Capacity, Aluminum Gray, 12 Tubes - SIKAFLEX 1A WHITE --- ## 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.ph/products/44754595-1a-polyurethane-premium-grade-high-performance-elastomeric-sealant-10-3](https://www.desertcart.ph/products/44754595-1a-polyurethane-premium-grade-high-performance-elastomeric-sealant-10-3) --- *Product available on Desertcart Philippines* *Store origin: PH* *Last updated: 2026-05-31*
